Hey! We found what “forced my lute” meant! Back in ye olde chemistry days, lute was a substance used to make seals between your various chemistry apparatus. So, Clayton was probably saying the 330 year old equivalent of “blew the seals” (or indeed, the pressure was sufficient to break the glass!). Oh, and somehow I missed pointing out when the Aladdin lamp was first produced. The trademark was obtained in 1908 and the first lamps went on sale in 1909. Also of note, one source claims lamps made after 1935 were technically side-draft designs, meaning air doesn’t actually travel through the center of the wick. So “central draft burner” as used in my script here might be considered a misnomer.
Yeah, the problem with that is when the counter does not return to zero by the end of the video it is visible to all. The way it is now, he has some plausible deniability to say "oops, I forget about xxx" in the comments or another video.
Lute, In Chemistry: it is a liquid clay or cement used to seal a joint, coat a crucible, or protect a graft. As for "protect a graft", again, in chemistry, it is referring to something like a long, thin, glass tube inserted through a hole made in the side of large glass beaker; the graft being that 'connection'. Whereas, again in chemistry, a "joint" is specifically where two ends are 'joined' together. Thus, the phrase, "...forced my lute", means that it broke through material that sealed and connected the 2-piece glass made item together.
ISTR it wasn't always easy to remove a soot spot, it could take a while fiddling with the wick to burn it off because too low and there wasn't enough heat to get it glowing, but turn it up a fraction too high and you'd see the yellow flame licking up the outside of the mantle. I still have an Aladdin of the type we used in the 1970s, but haven't yet had a use for it, Kerosene OTOH is a useful degreaser, I usually have some handy.
@@grumpus27 have you tried Coleman $1 socks retrofitted to the Aladdin? I went to order new mantles last year and was just shocked ($38 for one). Went to the hardware store, bought a pack of two Coleman aftermarket soft mantles for 2.25. Tied one to the harp base and ring. Sprayed it with my wife's AquaNet till it was stiff and the right shape. Works fine.
@@MrBilld75 Come to think of it, it looked similar to the disintegration effects I've seen recently catching up on the Marvel shows. Or rather, Marvel have captured that disintegration effect wonderfully in their CGI.
“It forced my lute.” When devices were made that had pipes or other attachments added to them which need to be made air tight or pressure resistant, a paste of some sort was prepare and applied to the joint. This paste was referred to as “luting.” Moonshiners used a paste of barley or rye flour mixed with water.
Sounds plausible. This means that 'forcing the lute' and 'breaking my glasses' might imply that pressure was building up in the destillation apparatus. The pressurized/quickly expanding gas either forced the joints to leak or simply bust the glass equipment.
As a young boy in rural Philippines, I enjoyed watching my father light our Petromax lantern that had a mantle. I still remember my elation whenever the mantle would suddenly burst into brightness as it got heated and immediately flooded our dark living room with an intense light. Yes, whenever the mantle needed replacing, he would buy one from the town hardware and the new mantle would seem to me like a sock that he would fit over the lamp's burner. I did not quite understand how it worked then and I was just fascinated by it. I brings me happiness, now as old man, to remember these things.

My 92-year-old mother who grew up without electricity knows all about these lamps. Matter of fact there was one left in The Farmhouse and when we had a power failure amazed how much light it puts out
Hard to believe we've gone from burning fuel for light to color-changing wi-fi enabled LED smart bulbs in a single person's lifetime. What's even crazier is that we already take our modern lighting for granted.
@@methos1999 ....well technically fuel is still burnt to generate electricity to power led bulbs & other appliances. Today World industry is just trying to cut off the fuel usage by turning everything to electrification.
@@methos1999 The gap in technology is I assume exaggerated by their rural upbringing. Some notable events of 1931 include the completion of the Empire State Building, the first non-stop flight across the Pacific Ocean, and the invention of the particle accelerator.
I'm a landlord in the UK and occasionally I come across the lead pipes used to feed gas matles from well over 100 years ago still buried in the walls of the houses.
People still use the Alladin lamps on remote ranches and mining claims especially at high altitude because it gets too cold for propane to work, and they don't have or can't start a generator. An alcohol or kerosene stove or heater will also still work at very low temperatures.
"lute" means something like putty or cement... So I would interpret "forced my lute" as "It broke the seals on my still" (so pressure was building, becuase a gas originates from the heated coal and this gas could not be condensed, as the guy wrote before)... And it "broke my glass", so after he enforced the seals, the glass broke, because it couldn't hold the pressure...

It is very easy to get a filament extremely hot for a couple of seconds. It's very hard to get it extremely hot for much longer. An electrical arc (especially one of the temperature needed to produce good light) will absolutely vaporize its electrodes over time as well, but it takes much longer for it to do so than it takes for a carbon filament to burn itself out in atmosphere. Even a tungsten filament will rapidly oxidize under the same conditions. The fact that filaments need to be quite thin in order to produce good light (due to light only being able to escape at the filament's surface) certainly didn't do them any favors either.
Gravedigging a 2 year old comment, but a lot of breakthroughs in history were discoveries of material science. Once you get something with a property you haven't had before, suddenly a lot of applications become possible. There's actually a theory that the tea culture in China held them back this way because it prevented them from discovering glass as they used porcelain pots and those were fine.
@@dojelnotmyrealname4018 the version I have heard for the China theory, from an anthropological perspective, is more due to the fact that East Asia has a lot of clay that is really good for making high-quality porcelain, part of the reason that to this day many English speaking countries call high quality porcelain products "fine China" - the clay needed very little refining before it could be fired into a quite well made porcelain.
I'll never forget the first time I went camping in the 90s, and my dad lit up a Coleman lantern. Damn near blinded me, and he said the trick is to set it up in a direction you don't need to look. We'd toss a rope over a sturdy tree branch, hoist the lantern up to about 8 feet off the ground, and tie off the line. It was like having a shop light in the woods!
@@no_peace quite frankly a light that bright would likely scare away anyone or anything because a human would probably come to the conclusion that if there is a light of such intensity the human that created it is probably still awake and an animal would see such a light and go I have no idea what's going on I don't want to know because I'll probably die if I find out I'm going to go the other way.
Even the term "Strumpflampe" "Stocking Lantern" was quite common. My Grandmother used it often to distinguish between gas mantle lanterns and (standard) "Petroleumlampe" (flat-wick kerosene lamp). And the "Petromax", which burns pressurized (with a hand pump) kerosene within the gas mantle is legendary ...
Please heed the safety instructions! The lamps must be monitored during use. DO NOT light and walk away, as the flame increases as the lamp heats. I did this once, lit, turned flame very low, got distracted, smoke alarms went off and red flame was roaring out the top of the chimney. The lamps are still used in rural areas, by the Amish, they tell me, and mantles, wicks and burner parts are sold in one local hardware. I collect them, they're fun to tinker with, a pain to trim the wicks, but fun to just turn off the lights and watch the lamp run.
I was raised with aladdin lamps, only 65 years old, we built home made diesel lamps for using while milking cows. My neighbour still doesnt have electric, his mother in her hundreds has moved to a house with electric but she was carrying coal buckets at 99, she couldnt start the generator so had to wait till her son got home, the generator would only run for a while at night. ( We installed electric in several farms when i was young). (In Scotland).
Norma,I am wondering if the old style Aladdin lamp idea with an incandescent mantle could be adapted to a mantle lamp that uses Bio Ethanol for fuel rather than Kerosene/Paraffin. Ethanol burns much hotter than Methanol and carries far less toxicity issues with its use. As far as wicks for burning Bio Ethanol are concerned I already use homemade wire filament wicks in small bottle type burners. I think there may be some worthwhile experiments in adding an incandescent mantle.
@@windyfarmer.6095 I never had them as a kid but when I started going to rural areas in the 70's all the types were very common, flat, Dietz and Alladin and the Coleman types.

"Lute" can be defined as "a clay or cement used for sealing a joint or coating a crucible." So, I imagine, in this case, "forced my lute" might mean the gas cracked the cement he used to attempt to seal the gas inside a container? Maybe indicating that the gas was under a lot of pressure somehow? Just a guess...
That's most likely what he meant. The distillation of coal has to be done in an air tight vessel, such as when they made town gas or coke or when burning wood to make charcoal.
The author was quite likely precisely describing what physically happened, but we are so used to these old-timey mechanical phrases being used for dramatic flair it is hard to hear it that way. Imagine an electrician working on a circuit and saying he blew his fuse; he would probably be talking about the actual fuse in his system.
This was my guess also. If you look at the retort, there is a hole in top to fit a stopper or additional fixtures. "Forced my lute or broke my glasses" sounds like, "popped my cork or shattered my retort."
The Coleman fabric mits reminds me of my childhood. Going camping using the propane lamp. I can still remember the hissing sound and bright light. The moths and other insects buzzing. The smell of the campfire.
“Forced my lute” means the gas pressure broke the connection to glass collection vessel meant to condense the gas vapor distilling from the retort. Typically, the gas would condense into a liquid, but the temperature would not have been low enough to condense the gas from the coal, so the pressure built up and forced the connections apart.

@@BurkenProductions Erm, what? ......... My content was supposed to say, that the length of the video just flew by, because those were some entertaining 30 minutes.
When I was a kid we used to use those Coleman lanterns all the time on hunting and camping trips. If I remember correctly, you never wanted to touch the mantle itself; if you did, it would just disintegrate into a fine powder when you touched it.
Same, apparently it was "petroleum naphtha" liquid fuel that had to be pressurized by hand for the first few minutes of operation. Then a generator of some kind used heat to keep the feed going. I was always getting in trouble for being too rough with it. Tying on new mantles took a bit of finesse.
@@frederf3227 Yup. You used to be able to buy "white gas" fuel (I've been told it was simply unleaded gasoline) at service stations. When I was a kid, every family camping trip started with a trip to the gas station to buy a gallon of lantern fuel. I remember my dad pumping up the fuel tank of the old Coleman lantern when the light started to dim. I prefer propane.
@@dstone1701 When I was a kid, my parents joined this cult up in the woods. We used a lot Coleman lanterns. I could never figure out the how and why of mantles. I think somebody gave me a really bad (and very wrong) explanation, but watching this video has clarified the science behind it.
@@dstone1701 This is the stuff. en.wikipedia.org/wiki/Naphtha It's the only thing we used in our Coleman lamps and stoves back in the 70's and 80's before the little propane cannisters became a thing. Before reading the Wiki page I had no idea it was the same thing as the 'lighter fluid' my dad used in his Zippo.
@@dstone1701 the white gas evaporates completely from your fingers and gear and doesn't leave a residue or smell. I prefer the white gas to propane as it's more energy dense, has lighter containers on account of not needing to be stored at high pressure, easier to see how much you have left and better for cold weather, but white gas is certainly fiddly with the pumping. On a nice summer daycamping trip, propane would be so much less trouble.
I was born in 1947 in the USA. I am familiar with gas lights that were in my Grandmother's Victorian home. They were converted to electricity before I was born. I also remember outdoor kerosene lanterns that were used outdoors by road construction crews and railroads. I started collecting various bicycle, flat wick farm, railroad, and camping lanterns decades ago. Also have a few hollow wick lanterns and heater brass fuel reservoirs. My BSA Troop used Coleman white gasoline lanterns and camp cook stoves that had to be pumped up the be pressurized. The lamps were so bright that you could not look directly at them. Thank you for this walk back in time.
5:20 There are "gasometers" in my train simulator. For years I could not figure out what these were or how to use them. After all these years, I finally know what one is.
Many interurban railroads were founded by coal gas companies in order to normalize a product of gasification of coal: electricity. If you could ride an electric interurban from Elgin to Chicago, you could safely put electricity into your house.
We have quite a few still in the UK - no longer operational but the structures are still there. They're all slowly being taken down & redeveloped which is for the best, but it is a shame to see the structures go
@@markwilliams2620 And now a good part of the former Elgin route is the Robert McClory and Skokie Valley bike trails. It was a lighter grade of rail than what Metra uses which is shared with freight.
@@roseroserose588 the redevelopment may be premature... if we are serious about moving to renewable gas they would be very useful. The modern gas holder has a membrane inside an outer dome. The outer dome is inflated by air (like a bouncy castle) and always looks the same. The gas bag inside inflates and deflates with the gas level. If there's a gas leak, you can detect it in the "overflow" air of the outer dome.
So I did a ton of undergrad research into lanthanides like the yttrium used in that mantle and I can say there is no catalytic reaction going on. What is happening is just that the correct fuel to air ratio is occurring and a non dirty flame is happening. That dirty kerosene smell that comes from the Dietz lamps is due to the candle not being able to burn hot enough with enough air to actually burn all the fuel. The aladdin lamp is providing both enough airflow and draft that the flame can get hot enough to burn cleanly.
They are very, very, very slightly radioactive. Not at all dangerous, just enough radioactivity that you can demonstrate with an alcohol vapor chamber in a high school science class (they emit alpha particles which leave behind big, fat clouds of alcohol vapor).
There are still a lot (about 1750, I think) of gas lamps in London. They're scattered around Westminster and the city. Others that look alike have been fitted with electric lamps. A team of six people maintains them, which includes winding up the clockwork timer that opens and closes the valve. The mantles come from Germany.
@@Biggles732 No. Acetylene burning in air gives a very yellow, VERY sooty flame. Which is quite nice - we used to use them for caving, under the nickname of "stinkies". (The calcium carbide used to generate the acetylene often had traces of calcium phosphide, which produced phosphine gas and a very distinctive smell.) You are probably thinking of burning a mixture of acetylene gas pre-mixed with oxygen before being fed into the burner. Two gas bottles (or a generator and an air pump) feeding two hoses in one burner. Which *does* produce a bright blue flame.
I was blown away 20-30 years ago, taking the family camping, I picked up a Coleman propane lantern and had to figure out how to tie those little mesh bags onto the pipes. I could not believe how bright that thing lit up and never understood it. It was so amazing, it's stuck in my memory to this day. Finally, today watching your video I get it. Kind of. Thanks!
ain't yet watched entire video... Those mantles represent the first commercial use of rare earth elements/lanthanides . A number of the rare earth elements glow brightly at reasonably achieved temperature. Cerium and thorium especially I remember. Thorium was the best performer and no longer used today . A fresh mantle is a cloth impregnated with nitrates of the rare earths and a silicon based chemical perhaps ammonium silicate. After commissioning by burning the installed mantle in situ, the ammonium and nitrate components and cloth cellulose are volatiled away leaving the rare earth oxides within a newly formed silicate solid structure that has formed in the matrix of the previous cloth fabric with some 40% shrinkage .

It is real similar to "burning out the carbon". This was a technique used in the 1940s thru 1970s to improve automobile performance and mileage. Slow driving results in low engine temps, which led to carbon build-up on valves and seats, thereby causing incomplete sealing and poor performance. Occasionally , we would take the car out to a straight stretch of road and drive as hard and fast as possible. This would burn the carbon build up off the valves, and the car would run better. The proof was all the black smoke that would roll out the tail pipes during the first run. And for all the smart alecks, who are going to say THAT was oil leaking around the valve seals? You're just wrong, and obviously too young to have "been there". And too sure of your own, obviously inadequate knowledge. I was there, being now 72yo, and I also have a Masters in Mechanical Engineering.
Here’s another interesting connection. When electric lighting was first being installed in buildings, they already had a route to run the wires: the gas pipes. The electric fixtures went up right where the gas fixtures had been, and the wires were pulled through the pipes that were already there. This way, electric conduit was “invented”.
Source? If you've pulled wires through actual conduit you know how hard even that is. Pulling wires through gas pipe seems almost impossible; the elbows are too sharp and the pipe has most likely not been reamed at the ends. I call BS
@@pasad335 Thanks for the reply. I don’t recall the source; sorry. You make a good point. I bet that the insulation could get stripped as the wire went a joint where the pipe ends were not reamed. But still, it could have been how the practice got started. Then, subsequently, people figured that they needed to have tubing that is more suitable for wire; curvy bends and free of sharp edges.
@@davidkantor7978 Yeah, interesting. I'm guessing some of the early gas piping was probably bent brass tubing. That could certainly work as electrical conduit.
IN the 1960s, there were power strikes in the UK for three hours at a time. I was staying with my aunt in London at the time, in an old house which still had working gas fittings in some rooms, although they'd not been used since the 1930s, when electricity had been installed. With some difficulty, I found a shop still selling gas mantles and fitting them enabled us to continue with gas lighting during the power cuts. It was a pity that the TV wasn't a gas one, too, but we did have a battery-operated radio!
1972, not the 1960s. I remember coming home from school, unlocking the front door and lighting the candle sitting on the table behind the door. It destroyed the Heath government and the next two general elections brought in a Labour administration until 1979. And I was a volunteer election worker in all those elections. The power workers weren't on strike - it was the coal miners. Now only a couple of percent - often less - of the country's electricity comes from burning coal. Because Thatcher (hawk, spit!) hated the miners.
@@HadleyCanine it’s kind of neat though not sure if it’s dedicated video worthy. As memory serves though later called “Vaseline glass” it used to be called uranium glass. I’m sure you can guess why. Indeed uranium glass was a thing, and yes it had uranium in it. Technically the process turned it into more of a ceramic glass. The uranium allows you to temper it at a higher temperature and gives it that opaqueness. On second thought, it could be viable for a dedicated video. There actually is a lot to that process now that I sit and think about it.
I’m fascinated by anything which burns kerosene for energy, I have fridges, irons, stoves, heaters, but my favourite collection is over 200 Aladdin lamps from model 1 which was a brass body lamp through to the current glass models. Here in Australia Aladdin revolutionised kerosene lighting with their mantle lamps for all the reasons you’ve mentioned and Aladdin lamps are still used in some Outback locations today. Electricity is sometimes impractical to supply to extremely remote locations, so kerosene is still popular, it’s cheap, can be easily bulk stored, more easily than propane, and it doesn’t need wind or sun to run, plus the non pressurised Aladdins are silent. Aladdins are expensive though, even today, particularly some of the rarer models collectors are interested in. My mother told me when she was a young girl growing up on the farm with no electricity and only kerosene wick lamps and candles for lighting, only rich folk could afford an Aladdin lamp! Love the show. PS I’ve spent hours trying to get Aladdin burners to burn more evenly, it’s almost impossible, particularly model 23’s. I like your theory about wick thickness inconsistency, never looked at that closely. Steve from Aus.
@@Conservator. Some folk certainly use battery power and solar in the outback and particularly in urbane areas, but some parts of the outback are extremely isolated, therefore kerosene is a more versatile option as it can be used by devices other than lighting.
I was born in a farm cottage that was lit with “Aladdin” lamps (mid-1950s)…if I remember correctly my dad converted a couple into electric table lamps (these were ones with metal fuel tanks, so he drilled holes in them to run cables). They even had lampshades because the original light from the mantle was so white and harsh.
Farm cottage , Yorkshire 1950s, great comfort in light & heat , also for carrying around the lambing fields ! The mantles were very fragile , like ash , and the light significantly brighter & more useful than a simple flame, The heat emitted was significant, but heated the room , and I think that some were adapted to heating a small cooking pan. Also I read that Thermo-couples were fitted to make electricity , long ago !
I was expecting to hear "carbon needs to be hotter to glow, as we see here as the soot is collected by the mantle".. as that was one of my first questions, why not use carbon mesh. It shows it so nicely, one of them glows, the other doesn't. You probably can't make carbon mesh to glow that brightly without using hydrogen and oxygen, or acetylen+oxygen.
Yeah, the 2nd word always has to be a greek one (meter), and if not, then at least a french one (reservoir)... Or else, everybody will know, that you don´t take your business seriously...
I am familiar with hurricane lanterns and Coleman lanterns, but I never heard of the Alladin variant. I've always wondered about how mantles actually work and what they are made of despite my using them numerous times. Thanks for your thorough and interesting video.

Alladin, Coleman, Tilley, Primus, Optimus - they're just trade marks. Effectively doing the same job, but with *non-interchangeable* parts (jets, prickers, pump washers, seals ...) for "vendor lock-in" - which has been around since the Victorians. The only reason the mantles are interchangeable is because the few *mantle* manufacturers don't want to sell 4 different product lines, and just make a one size fits all".
Gasometers were a part of my childhood (and deserve an episode of their own). They were everywhere in those days (50s and 60s) and you could while away hours and hours 'watching' them rise and fall (much like clocks, you knew they were doing it, but could never actually see them move!). The sections were sealed with water (or rather the lower sections were stored in a circular trench of water), so when they were full, the top section looked OK, but the lower sections got progressively more rusty. We had an old disused one outside our flat until quite recently (early 2000s), and I've not seen any others locally since it was dismantled, so it must have been one of the very last ones still standing. Although they were, of course, used for storing gas, their main use was to maintain a steady pressure in the gas main. A very simple answer to a very tricky problem.
Interesting... so in a way they did "measure" something. Not just the amount of gas currently inside, but also the relationship between the generation and usage rates.

I live in a part of California that loses power a lot so my family used to have a lot of lanterns in the cabin. I always loved when there would be a blackout because then our cabin would look like something from the 1800's, especially since my dad loves antiques. My favorite was always my little railway lantern, but when dad wanted to do some wood carving or something in the living room, he would light up one of those aladdin lamps and boy howdy did they glow bright! Thank you so much for this entire lantern series! It has been a blast to learn more about the history of these marvelous illuminators!
I have no idea what “forced my lute” means, but “broke my glasses” sounds as if the gas pressure built up inside his apparatus until it broke his glassware
Lute was a material used for sealing alchemical apparatus back in the day. So combined with the next phrase, I'm pretty sure he's talking about it actually breaking his equipment.
What wonderful memories this brought back to me! My maternal grandparents lived in a stone cottage in rural North Wales and, in the 1950s, had no electricity. It was so restful sitting in the "living room" in the winter, with the coal range and an Aladdin lamp on the table producing enough light to read by even if not at the table. Even though the fire was usually kept low to save coal, unless you were boiling a kettle or baking in the small oven built into the range, the room was indeed kept warm by the heat from the Aladdin lamp. At bedtime, you used an old-fashioned candle holder to walk down the narrow passageway to the bedroom, where it was much colder, and the candle was put out as soon as you were in bed, leaving you in total darkness. I would not be upset if I was forced to live like that again, especially in such a beautiful part of Wales.
Same here, in NW Scotland, we only got connected to the grid in 1979 I believe. Great memories of the gentle hiss of a Tilly Lantern, and the incredible ,soft light that they produced. I am seriously considering going off grid again now, it’s funny how everything comes around…. I can still remember the smells of paraffin and methylated spirit- I was fascinated by the beautiful purple colour as a kid! 👌
My Grandparents had a cottage on an island from the 80's up to the early 2000's. Up until about '95, the whole place was powered with propane. Lights, stove, even the fridge, all propane powered. The water was pumped from the lake with a gasoline powered pump to a small water tower. After the electric upgrade (which would be wildly expensive today), the stove remained propane, and one light, in a little corner with a comfy chair, and a perfect view of the lake, the perfect spot to curl up with a book, was left alone, it still works.
Asbestos is still in very wide use today in the US. It is just not used in residential settings, only certain industrial uses. And it is no more of an issue than gasoline is. Asbestos is perfectly fine as long as you don't create dust. Gasoline is perfectly fine as long as you don't let it create vapor.
When I grew up the gasometers in the local town were quite visible and they had scales up the side so you could tell how much gas was in them so they were in affect measuring devices.
When the centre is high the container is full as the contents is used the container falls, the weight of the container pushing against the gas inside giving gas pressure in the pipes.
For anyone in Aus born before 1970 gasometers should not be a mystery. Given that , even without measurements on the side, it's possible to gauge the amount of gas held at any time, "gasometer" is the most appropriate name for them.
Two massive units were astride the 405 Freeway in Long Beach, California -- for years. They eventually became buffers for the adjacent refinery -- IIRC. This was the same refinery that Cody Jarrett blew up in "White Heat." He was atop spherical propane-butane tanks... a bad place to smoke. They must be gone by now -- so old -- and sitting atop valuable land.
Occasionally a gasometer would blow up. I remember one did so in Copenhagen in the seventies causing great damage as domestic housing was built much too close.
This was the first experiment I taught to my Introductory Physical Science classes. Wood splints were heated in a test tube retort and it was observed that a new solid (charcoal), a flammable liquid (wood alcohol) and a flammable gas was produced. The wood could be decomposed into new substances, but not put back together. A great experiment raising many questions.
In my encounter with that as a student, the teacher used a cigarette instead of a wood splint. The stuff that came out of that served to make me a lifelong non-smoker.
Interesting and informative video. I remember many years ago having a Coleman lamp with the bag shaped mantles like at 17 minutes. When new, you had to burn off some material that was blue if my memory serves me right. After that, they worked well, putting out a lot of light. The fuel it used was naptha.
I remember the Thorium nets. We had a lamp with one when I was a kid and used it on all our camping trips. My father, then a physics teacher, had access to a Geiger counter and just for giggles he brought it home and pointed it at the lamp. The noise that followed was quite scary. We didn’t stop using it though. Different times. 😳

Yep! My dad would sometimes bring us to his cabin near his little hobby apiary. There was no running water or electricity, so we'd use this kind of lamp with a propane bottle. I was very fascinated by the glowing fabric and he'd always tell me to not touch the mantle, said that it'll give me cancer. That was 15 years ago.
My dad was a doctor. We lived in the south and the mosquitoes were fierce. Back then, mosquito repellents weren't very effective. He made a mosquito repellent that worked perfectly. Just apply it liberally all over your body and you never got a single bite. It was kerosene and sevin mixed together. Amazingly, I'm still alive and in good health. He was quite aware of the risks but insisted that it was still healthier than getting 100s of bites every day.
Thorium goes through alpha decay, so it's not that dangerous as long as it's outside of your body. It becomes dangerous when you accidentally inhale or swallow the radioactive dust particles, which is a real possibility with a mantle.
It's notTHAT dangerous for the user, as long as you don't let the pieces of the mantle get into you (harder than it sounds, as it's basically ash, but not that hard...) It's the manufacturing (especially back when nobody knew anything about radioactivity, and dumped thorium waste like it's nothing) that's the real trouble. Some of the old gas mantle plant sites are still being decontaminated.
Back in the day (the 1970s), we went camping with a Coleman lantern that had two of what we always called 'booties', and I remember they were considered to be VERY fragile and at the time I remembered them to be radioactive in some way.
When I was younger, the Coleman lantern was the choice for camp lighting. I recall a 21 year old intoxicated me grabbing a Coleman that "brewed up" in a friend's camp and setting it on a rock ledge outside where it could burn itself out safely. It was a fun stay. Later that night we watched FB-111'S flying in and out of Plattsburgh AFB 20 miles away. The next morning, we were all recovering from the night before... eating eggs and rabbit hash out on the ledge when an A-10 flew up the valley. We were looking down at the pilot, who saw us waving and waggled his wings. Good times.
2:18 Fun fact, that letter would have been written while there were still indepedent Maya city-states. The last one to fall to Spanish campaigns only did so in 1697, 6 years later. I wish I could provide an additional tangent that ties Mesoamerican civilizations into the topic of the video, but sadly there is no extremely clever pre-European adaption of fossil fuels for lighting in Mesoamerica, though if we're talking about things like sanitation/hygine practices and processes, medical, botanical, and agricultural science, etc, I can think of a number of examples. If you ever cover toilets, dyes recycled from human waste, gardening, aquaculture, herbal remedies, Nixtamalization, cements, surgical rods for setting bones, etc, I'll have a lot to talk about!
@@noalear I have, sort of: I don't have any on my channel, but I've acted as a consultant for a few other channels, like Invicta History's Aztec rank video, Cartoon Universe's video on Onyx Equinox's Mesoamerican influences, and Ancient America's video on Teotihuacan. I also do long essay content on other websites, and retweet and reply to a lot of historical stuff on twiter (I'm @Majora__Z there)
There are also the legends of El Dorado or similar, where IIRC, explorers broke into chambers and/or tunnels and observed lighting that they assumed must have been burning for several centuries (since they were the first ones to have been in there in a while).
My dad took me gigging with a tilley back in the day. Then I took it up with my friends using a gas lamp. Then a halogen H4 and a car battery. Now you could probably just use a key chain LED.
"someone asked for a simulated hurricane, I can't do that but" -proceedes to do that Lol I love this series, it's just the right amount of comical built into a very informative package to me.
I use a Coleman "white gas" lamp while camping. I grew up around these lamps. I remember my dad taking the lamp and pumping it to pressurize the tank. My dad used to pull out the mantle after the old one would get a hole.
I like the word gazomètre because the height of the cover actually gives a visible measure of how much gaz is in stock. And also because I'm french and this word looks far more french to me than gazofeet or gazoyard
We had a gasometer near us. The cylinder floats in water to make a seal. The more gas you have the higher the cylinder. This maintained a level pressure so I would say it could be classed as a Meter as it gave you a visual indication of how much gas you had left.
I used to work in gas utilities. The gasholder / gasometer is dual function (although we referred to the locations as holder stations), town gas was produced around the clock and natural gas is transported likewise. So local storage during low demand was needed as they function at relatively low pressure. Also release gas to the system during high demand, regulating pressure. They have become largely obsolete as the supergrid network can be over pressured for storage and exhausted gas fields can be re stocked. Yes putting gas back underground is a thing.
Cool video. When I was in the Canadian Forces from 1980 -1997and I was posted to Comox BC in 1991, one of my secondary duties was as a member of the Nuclear Emergency Response Team (NERT). When training with the equipment to used to detect and locate radioactive material, we used live Radioactive material and of course a much safer training material. That training material was the new (unburnt) Coleman mantels for the lantern which worked well as a training aid.
I bought my Aladdin lamp at a local hardware store about 15 years ago. I had been using propane fired gas lights in an older camping trailer and wanted the option of using a kerosene source. My brother had used an Aladdin lamp in his home 40 years ago which had a fixture which would allow him to hold a pan for cooking above the lamp. That provided an increase in efficiency, light and cooking, and enough heat to take the chill off the cabin on cool, but not too cold, nights. We had used Coleman lanterns fueled by white gas back in the 1950's, so we have used all 3 types of incandescent mantle lamps over the years. Although I still have all these lanterns, the great improvement in efficiency of LED lights and rechargeable batteries may mean that they will just be relics on the shelf as curiosities. This presentation provided some interesting history and details I had not been aware of.
"forced my lute" lute was for sealing and fireproofing different components in chemistry. He may be saying it caused enough overpressure to break the seal been the retort and... Something else
I run an isotope handling course at a university, one of my props (among many) to demonstrate the response of the contamination monitor is a thoriated gas mantle. They certainly send the Geiger tubes crackling.
I used to opposite a set of large gasometers in the UK and they were really useful to know what the weather was going to be like. If they were full, you knew cold weather was on the way because they were building reserves for the local gas heating I guess in that way they were good for measuring things
As a technician, I was drawn here by the title and I found the content very informative and interesting. What fascinated me most is your use of and skill in English language. Not too common for a person covering this type of a topic. A master orator.
What fascinates me is seeing a comment like yours. I find his style of presentation so grating that I quit the clip two minutes in, even though the topic's quite interesting. I have a severe aversion to the cheap gimmick of pretending that ideas are taking the speaker by surprise when it's obvious that they aren't; e.g., his way of mentioning that _retort_ doesn't mean another sense of the word, etc. It reminds me of a typical script from _Friends,_ i.e., makes me want to puke. Okay, it just makes me shudder, but either way, I don't watch anything presented in that style... and SpewTube is infested with it. Anyway, he's the very opposite of a master orator.
@@bsperoz well the song was written under the same assumption, it's about living a life on stage, as a celebrity or other public figure who would be in the literal limelight
or maybe telling someone to stop trying to force my lute. "you may not like what i have to say but trying to force my lute isn't going to change my mind." their confusion over what you just said should buy you enough time to make a quick egress.
If the guy talking about a lute being a clay seal on a crucible, then us taking this phrase on as an expression for frustration will make for some wonderful reading on an encyclopaedia one day. Let's do it.
Extremely interesting. Really appreciate bridging the gaps leading up to electric light. Your research and presentation ability, attention to detail and admission of imperfection in knowledge in some rare but understandable cases make your videos a true pleasure to watch. It amazes me how curious you are about such a wide range of topics.
Some of my fondest memories from childhood are watching my dad change the mantles on our Coleman lantern before heading out to 'the land' for a hunting weekend. And then the gurgling hiss of the lantern lighting up our entire campsite from pitch black. Good times.
The steel mill that I work harvests the various byproducts from the coke ovens, including coal gas. They actually use the coal gas as fuel for the coke ovens themselves, as well as various other things like boilers.
Gas lights is where we get the phrase “TURN the light on”. As you said, there were valves; not switches. Thus, you really don’t “turn” on an electric light, but the term had been established and just stuck.
@@erinfinn2273 No - electric switches and gas valves are wildly different. The designers wanted to maintain familiarity however. Wiring was however run through the old gas pipes - which is why American electrical conduit still uses pressure tight threads. The other power source in most cities was water - the hydraulic power systems continued in service until the 1960’s running lifts. The hydraulic power pipes in London were repurposed in the 1980’s for fibre optic cable runs.
@@allangibson2408 I guess what I meant was that the interface was just repurposed. I do know the mechanical differences between gas and electric switches. You just said what I wanted to say clearer. Edit: I made that post when I was very tired. I mean no disrespect to anyone's intellect. Also, didn't know about the municipal hydraulics system. That's cool.
You've done it again! This is the second video of TC that I've watched and like the first, it is so entertaining and educational, both at the same time. You're such a natural explainer of complicated things.
I do appreciate more and more the cleverclogs concept of the mantle, and the entertainment factor of alarming people with a roaring geiger counter never gets old, I still forever associate them with the seared-in memory of being utterly blinded by that hissing nightmare on camping trips. "Enjoying all those stars? Here lets light up the GODDAMN SUN right at eye level"
indeed. In boy scouts, they had them on long poles attached to propane tanks like you'd find in a gas grill. And they had 5 of them for the main area, obliterating your night vision so you'd find every ankle-busting root on the way back to your tent....
That's interesting. I had a house in Scotland that still had some old lead gas pipes in the walls for lighting but they were only about 1/4" inside diameter.
@@Phiyedough Yes... our house in Los Angeles was built in 1914 and had gas light fittings in every room. Electrical wiring was installed later, obviously. As a young kid, I wondered why the gas outlets were so high. Of course, they were for gas lamps. The house is still there and probably still has the hidden gas pipes running through every room (of course, empty).
I have a lamp which was originally a gas lamp. It was converted to electric and the wiring runs through the remaining gas fitting on the base of the lamp. Had my brother (owns hundreds of kerosene lamps) not told me, I would never had known it wasn't originally electric.
I like seeing how things are invented and created. And it just shows people new how to do it from way before they just never pressed on to actually master it and obtain utility. That is why I believe we are more advanced than we think, and we need to discover less and tie more ends to get what we want.
Speaking of town gas, I'm just old enough to remember the giant gasometers in St. Louis. They were these huge tanks that looked like cylindrical cages with a large balloon that filled up and down according to supply and demand. I always thought they were super cool!
I mean, that isn't too far off. It was more of a "blew off my rubber hosing" thing, but the implied pressire of the flammable gas in question is pretty applicable.
I just posted a comment on this, I think he might be using a lost euphemism for sneezing. (something strummed him and he put forth sound). Like the classic cartoon honk sneeze, along those lines. People where I *think more clever with language and writing in earlier times. Qualifier: I'm no expert
Fascinating stuff. As an old man now (b. 1954), I have seen some of this technology in use, and heard more about it from my father. When on holiday in caravans, we would use gas lighting with mantles. They tended to burn brighter the longer they burned, so you had to reduce the gas flow after a while. Eventually, the fragile ash mantle would fail, either due to the carbonisation you mention or because vibration in the caravan would fracture it. My father was raised in a house where the only source of lighting came from 'fish tail' gas lights. He took a candle with him when he went to bed.
Your video was so much fun. I'm 66 and originally from the UK. When I was 5 my parents were really poor and we lived for a few years in an uncle's holiday cottage that didn't have electricity, so it was illuminated with gas mantles everywhere. This was before the advent of Methane/Natural Gas. One of the fun things you forgot to mention is that coal gas is heavier than air. So in the winter and if your house was sealed really well it could asphyxiate you and if you woke up and lit a candle it would blow the house and you to smithereens (lovely word). It had a distinctive smell much like essence of old engine oil, My parents reinforced the rule in both my sister and me that if we smelt it we were to yell and run outside. The only problem was that we always could smell it. I can't wait for your next video and I'm assuming you have a Tilley lamp in the video. I have two for our power failure kit because they are staggeringly bright and only a bit explosive. They can run on all the kerosene derivatives (Jet A1 works particularly well) although red diesel seems to gunk up the tubes after a while. You would have to be mad to run a pressure vapour lamp on gasoline so I bought one of Coleman lamps but it definitely make me itch when it's running. The Tilley lamp is hilarious because you usually set fire to a small bath under the mantle of methylated spirits to pre-heat the lamp to get it up to temperature. Once it gets going though it's so bright you can illuminate a whole campsite.
In Vienna there where some big "gasometer"'s that are now repurposed, but when they where holding has you could tell by how high or low the containers held by the structure where how full they where
@@alexe8375 well, the frames were moved to the other side of the canal and fancy apartments were built inside them. The material that actually held the gas was far too toxic to reuse.
There existed in my city, a gasometer, until about 10years ago. It was a 'listed' building. It was not actually in use. Then they decided to use the land for a supermarket. The telescopic dome floated on water which acted as a seal, and it expanded as gas was added.
I've used an Aladdin lamp for Years! On the northern California coast the closest electricity was miles away it gave off the equivalent light to a 90 Watt bulb plus it gives odd some heat that helped heat A slightly drafty cabin. Bonus: you can toast Smores three feet above the chimney!
Regarding the statement “these sorts of lamps can’t be used outdoors”, I lived in Houston TX in the early 2000’s and most homes in the neighborhood had filament style gas lanterns outside in the front yard lighting the path to the door. They were on 24 hours a day which I thought was terribly wasteful of gas. I accidentally severed the gas supply line with the lawnmower and the light went out. For the next 4 years I left the gas supply turned off, only re-lighting it when it was time to sell the home.
I was especially excited for this episode. My parents used to take us camping when we were young and we had one of those propane-bottle & wick lamps. It was always this mystical beast, being a combination of very powerful but also quite fragile. I was very excited to finally learn how it all worked.
Where I live we have naphtha lanterns for camping, I remember asking "what happens if we touch the wick while it's on?" The answer I got was "not only will you disintegrate the wick, but you'll also severely burn your finger."
I remember camping as a child in the 80s, and our propane lamps had a single wick in the middle, and a portable propane cylinder underneath. Larger than the one in the video, but smaller than a BBQ gas bottle.
I have both propane and gas lanterns. I mainly use the propane lantern though. I just bought a tree to put on my 20lb tank that the lantern can sit on top. Much cheaper to refill the 20lb tank than keep buying the little 1lb canisters plus the tree lets me connect my propane stove to it too. I also have an old 3 burner gas stove that has the propane conversion kit, which is just a pipe with a threaded end for the propane to connect to. Nothing else had to be changed other than to remove the gas tank.
@@jasonantes9500 So confusing reading the word gas in this context. My use of it was as a synonym for propane/butane, aka liquefied petroleum gas, LPG for short. We (Australia) understand the abbreviation gas for gasoline, in context with American cars, but our cars that run on gas use LPG or autogas. So my BBQ gas bottle referred to above was an 8.5kg LPG cylinder.
@@jemsterr Yeah, different parts of the world different vernacular. Yes, my use of gas is short for gasoline. I could have said dual fuel too I suppose. Anyway, cheers!
Thank you...I now understand what this gas mantle "thing" is. I encountered it as a concept for the first time today, and once I saw what new ones, ready to be used, look like, I was very confused as to how a fabric net bag became a helpful and desirable item once subjected to flame. GOT IT NOW. Much thanks, no more confusion. Very clever invention to improve the usability of the then-available technology. Can you imagine people being smart and careful enough to use this in their homes now? Drivers have trouble nowadays simply remembering to turn the headlights on for their cars at night...
This is the first time I've ever heard or read the name "Auer von Welsbach" from anyone outside of Austria. He did a crazy amount of different stuff, I can only recommend everyone to give it a read. I happened to go to school with one of his descendents (not into chemistry himself of course, but kind of cool). Oh, and he used a Bunsen burner for his lamp because he was literally a student of the man it's named after. He's also the original founder of Osram.
I know right, he was clearly pretty creative and contributed to many different fields like literally discovering a new element (Lutetium). Though, like you said, almost nobody seems to remember him now and somehow he almost vanished for good.
Echt interessant, hab mich grad etwas über ihn erkundigt und es ist tatsächlich sehr seltsam dass ich wie die meisten noch nie was von ihm gehört habe. Vielleicht war das aber auch seine Intention? Oder er wurde einfach vergessen :P Wobei ich den Begriff "Auermetall" schon häufiger gehört hab, wusste aber gar nicht dass es nach ihm benannt wurde. Hahaha und der Wikipedia Artikel über ihn beinhaltet: "Selbst war Auer die Personifizierung eines Forschers und Gelehrten, - ein systematischer und disziplinierter Arbeiter, der sparsam mit Worten und schriftlichen Aussagen war." Da scheint ihn ja jemand sehr zu mögen :D
The story that I have read is that Auer von Welsbach invented the gas mantle partly by accident. He was trying to separate and identify the different rare-earth metals and was boiling a solution of rare-earth salts in a flask that was standing on an asbestos mat over a Bunsen burner. Some of the solution boiled over and spilled onto the red-hot asbestos mat, and when it dried out it glowed brilliantly. Welsbach developed the gas mantle from this accidental discovery.
"In just the last video, we took a look at these hurricane lanterns, their history and how they work. This video will be covering the crazy path that brings us through the RCA company and how these defined how the CED video format was engineered." - Alec Watson (AKA James Burke Jr.)
I grew up using those Coleman propane lanterns while camping. Fascinating to learn about the technology because it made no sense to me as a kid. I just couldn't wrap my head around how putting a tiny sock in the lantern made it so much brighter.
I hope this series continues onto safety lanterns used in mining for some years. I believe they have a 'flame arrester' to prevent them from causing explosions.
they basically had a fine mesh that when the methane entered through it into the lamp it would safely burn without spreading the flame outside of the lamp. I'm not so sure on the physics of why that occurs but it does.
@@A.Martin It was demonstrated at the Royal Institute by Humphry David who invented the lamp. The way it works is that the screen is small enough to let combustion gasses through but not the flame front. The original filter was a bundle of tiny tubes that formed the screen which cooled the flame front to below combustion temperature so no flame could progress to other side of the filter. Think of a bundle of drinking straws but shrunk down by 80% and made out of brass. It was eventually refined by using a stack of woven brass screens with fine brass wire and each screen was spaced about a quarter of an inch apart. If you look at a miners lamp there's a large collar that looks like a hood above the light glass. The filter is housed in that hood.

Hey! We found what “forced my lute” meant! Back in ye olde chemistry days, lute was a substance used to make seals between your various chemistry apparatus. So, Clayton was probably saying the 330 year old equivalent of “blew the seals” (or indeed, the pressure was sufficient to break the glass!).
Oh, and somehow I missed pointing out when the Aladdin lamp was first produced. The trademark was obtained in 1908 and the first lamps went on sale in 1909. Also of note, one source claims lamps made after 1935 were technically side-draft designs, meaning air doesn’t actually travel through the center of the wick. So “central draft burner” as used in my script here might be considered a misnomer.

Stack memory, in assembly language
Lute, In Chemistry: it is a liquid clay or cement used to seal a joint, coat a crucible, or protect a graft. As for "protect a graft", again, in chemistry, it is referring to something like a long, thin, glass tube inserted through a hole made in the side of large glass beaker; the graft being that 'connection'. Whereas, again in chemistry, a "joint" is specifically where two ends are 'joined' together. Thus, the phrase, "...forced my lute", means that it broke through material that sealed and connected the 2-piece glass made item together.
THANK YOU!!!
Goat
who up forcing they lute
I assumed about the same. I wasnt familiar with the terminology, but I figured it meant one of th glass containers exploded or broke.
I thought the person meant "Force My Loot" as in "forcing treasure or valuables down through something".
22:45 I really appreciate you fully showing the carbon buildup disappearing. that was very satisfying
ISTR it wasn't always easy to remove a soot spot, it could take a while fiddling with the wick to burn it off because too low and there wasn't enough heat to get it glowing, but turn it up a fraction too high and you'd see the yellow flame licking up the outside of the mantle. I still have an Aladdin of the type we used in the 1970s, but haven't yet had a use for it, Kerosene OTOH is a useful degreaser, I usually have some handy.
Yeah it was, it was like a movie special effect and very cool.
Yes.
@@grumpus27 have you tried Coleman $1 socks retrofitted to the Aladdin?
I went to order new mantles last year and was just shocked ($38 for one). Went to the hardware store, bought a pack of two Coleman aftermarket soft mantles for 2.25. Tied one to the harp base and ring. Sprayed it with my wife's AquaNet till it was stiff and the right shape. Works fine.
@@MrBilld75 Come to think of it, it looked similar to the disintegration effects I've seen recently catching up on the Marvel shows.
Or rather, Marvel have captured that disintegration effect wonderfully in their CGI.
“It forced my lute.”
When devices were made that had pipes or other attachments added to them which need to be made air tight or pressure resistant, a paste of some sort was prepare and applied to the joint. This paste was referred to as “luting.”
Moonshiners used a paste of barley or rye flour mixed with water.
Like Fuji 9 luting cement!
@@FrancisCWolfe It allows you to do your own dentistry, too!
Sounds plausible. This means that 'forcing the lute' and 'breaking my glasses' might imply that pressure was building up in the destillation apparatus. The pressurized/quickly expanding gas either forced the joints to leak or simply bust the glass equipment.

As a young boy in rural Philippines, I enjoyed watching my father light our Petromax lantern that had a mantle. I still remember my elation whenever the mantle would suddenly burst into brightness as it got heated and immediately flooded our dark living room with an intense light. Yes, whenever the mantle needed replacing, he would buy one from the town hardware and the new mantle would seem to me like a sock that he would fit over the lamp's burner. I did not quite understand how it worked then and I was just fascinated by it. I brings me happiness, now as old man, to remember these things.

People still use the Alladin lamps on remote ranches and mining claims especially at high altitude because it gets too cold for propane to work, and they don't have or can't start a generator. An alcohol or kerosene stove or heater will also still work at very low temperatures.
"lute" means something like putty or cement... So I would interpret "forced my lute" as "It broke the seals on my still" (so pressure was building, becuase a gas originates from the heated coal and this gas could not be condensed, as the guy wrote before)... And it "broke my glass", so after he enforced the seals, the glass broke, because it couldn't hold the pressure...

I’m always stunned by the fact that arc lights, literal LIGHTNING in a tube, was invented before bulbs that just needs to get a filament hot
Arcing electricity is easy. But Finding a filament that wouldn’t burn was far more difficult
.
everything is easy in retrospect. @@electrictroy2010
It is very easy to get a filament extremely hot for a couple of seconds. It's very hard to get it extremely hot for much longer. An electrical arc (especially one of the temperature needed to produce good light) will absolutely vaporize its electrodes over time as well, but it takes much longer for it to do so than it takes for a carbon filament to burn itself out in atmosphere. Even a tungsten filament will rapidly oxidize under the same conditions. The fact that filaments need to be quite thin in order to produce good light (due to light only being able to escape at the filament's surface) certainly didn't do them any favors either.
Gravedigging a 2 year old comment, but a lot of breakthroughs in history were discoveries of material science. Once you get something with a property you haven't had before, suddenly a lot of applications become possible. There's actually a theory that the tea culture in China held them back this way because it prevented them from discovering glass as they used porcelain pots and those were fine.
@@dojelnotmyrealname4018 the version I have heard for the China theory, from an anthropological perspective, is more due to the fact that East Asia has a lot of clay that is really good for making high-quality porcelain, part of the reason that to this day many English speaking countries call high quality porcelain products "fine China" - the clay needed very little refining before it could be fired into a quite well made porcelain.
I'll never forget the first time I went camping in the 90s, and my dad lit up a Coleman lantern.
Damn near blinded me, and he said the trick is to set it up in a direction you don't need to look.
We'd toss a rope over a sturdy tree branch, hoist the lantern up to about 8 feet off the ground, and tie off the line.
It was like having a shop light in the woods!
The propane stuff will never beat the old multi-fuels

I always liked the German term for gas mantles. "Glühstrumpf" which literally translates as "glow stocking".
Technically not even wrong 😂
Even the term "Strumpflampe" "Stocking Lantern" was quite common. My Grandmother used it often to distinguish between gas mantle lanterns and (standard) "Petroleumlampe" (flat-wick kerosene lamp).
And the "Petromax", which burns pressurized (with a hand pump) kerosene within the gas mantle is legendary ...
In Portuguese it is called "camisinha", little shirt, which later became a slang for "condom".
It's called 'gloeikous' in Dutch, which means the same thing.
German is the most literal language I think drax is german
as guy from africa I remember mantels we used to use them were I lived, thank you for the storie and knowledge my friend and I whish you a nice friday
Please heed the safety instructions! The lamps must be monitored during use. DO NOT light and walk away, as the flame increases as the lamp heats. I did this once, lit, turned flame very low, got distracted, smoke alarms went off and red flame was roaring out the top of the chimney.
The lamps are still used in rural areas, by the Amish, they tell me, and mantles, wicks and burner parts are sold in one local hardware. I collect them, they're fun to tinker with, a pain to trim the wicks, but fun to just turn off the lights and watch the lamp run.
I was raised with aladdin lamps, only 65 years old, we built home made diesel lamps for using while milking cows. My neighbour still doesnt have electric, his mother in her hundreds has moved to a house with electric but she was carrying coal buckets at 99, she couldnt start the generator so had to wait till her son got home, the generator would only run for a while at night. ( We installed electric in several farms when i was young). (In Scotland).
Lehmans in Kidron OH?
Norma,I am wondering if the old style Aladdin lamp idea with an incandescent mantle could be adapted to a mantle lamp that uses Bio Ethanol for fuel rather than Kerosene/Paraffin.
Ethanol burns much hotter than Methanol and carries far less toxicity issues with its use.
As far as wicks for burning Bio Ethanol are concerned I already use homemade wire filament wicks in small bottle type burners.
I think there may be some worthwhile experiments in adding an incandescent mantle.
@@windyfarmer.6095 I never had them as a kid but when I started going to rural areas in the 70's all the types were very common, flat, Dietz and Alladin and the Coleman types.

Well, obviously he was startled by the lighting phenomenon he just discovered.
"Lute" can be defined as "a clay or cement used for sealing a joint or coating a crucible." So, I imagine, in this case, "forced my lute" might mean the gas cracked the cement he used to attempt to seal the gas inside a container? Maybe indicating that the gas was under a lot of pressure somehow? Just a guess...
You’re pretty much correct, though exactly what he was using to seal the joints is unclear.
That's most likely what he meant. The distillation of coal has to be done in an air tight vessel, such as when they made town gas or coke or when burning wood to make charcoal.
Could he have meant to say he "came undone"?
The author was quite likely precisely describing what physically happened, but we are so used to these old-timey mechanical phrases being used for dramatic flair it is hard to hear it that way. Imagine an electrician working on a circuit and saying he blew his fuse; he would probably be talking about the actual fuse in his system.
This was my guess also. If you look at the retort, there is a hole in top to fit a stopper or additional fixtures. "Forced my lute or broke my glasses" sounds like, "popped my cork or shattered my retort."
"But here's a leaf blower" is going to be my consolation response from now on.

"I can't get you a kitten. But here's a leaf blower." I'm not sure it works in every situation, but results would be amusing nonetheless.

The Coleman fabric mits reminds me of my childhood. Going camping using the propane lamp. I can still remember the hissing sound and bright light. The moths and other insects buzzing. The smell of the campfire.
“Forced my lute” means the gas pressure broke the connection to glass collection vessel meant to condense the gas vapor distilling from the retort. Typically, the gas would condense into a liquid, but the temperature would not have been low enough to condense the gas from the coal, so the pressure built up and forced the connections apart.

When I was a kid we used to use those Coleman lanterns all the time on hunting and camping trips. If I remember correctly, you never wanted to touch the mantle itself; if you did, it would just disintegrate into a fine powder when you touched it.
Same, apparently it was "petroleum naphtha" liquid fuel that had to be pressurized by hand for the first few minutes of operation. Then a generator of some kind used heat to keep the feed going. I was always getting in trouble for being too rough with it. Tying on new mantles took a bit of finesse.
@@frederf3227 Yup. You used to be able to buy "white gas" fuel (I've been told it was simply unleaded gasoline) at service stations.

I remember my dad pumping up the fuel tank of the old Coleman lantern when the light started to dim. I prefer propane.
@@dstone1701 When I was a kid, my parents joined this cult up in the woods. We used a lot Coleman lanterns. I could never figure out the how and why of mantles. I think somebody gave me a really bad (and very wrong) explanation, but watching this video has clarified the science behind it.
@@dstone1701 This is the stuff. en.wikipedia.org/wiki/Naphtha
It's the only thing we used in our Coleman lamps and stoves back in the 70's and 80's before the little propane cannisters became a thing. Before reading the Wiki page I had no idea it was the same thing as the 'lighter fluid' my dad used in his Zippo.
@@dstone1701 the white gas evaporates completely from your fingers and gear and doesn't leave a residue or smell. I prefer the white gas to propane as it's more energy dense, has lighter containers on account of not needing to be stored at high pressure, easier to see how much you have left and better for cold weather, but white gas is certainly fiddly with the pumping. On a nice summer daycamping trip, propane would be so much less trouble.
I was born in 1947 in the USA. I am familiar with gas lights that were in my Grandmother's Victorian home. They were converted to electricity before I was born. I also remember outdoor kerosene lanterns that were used outdoors by road construction crews and railroads. I started collecting various bicycle, flat wick farm, railroad, and camping lanterns decades ago. Also have a few hollow wick lanterns and heater brass fuel reservoirs. My BSA Troop used Coleman white gasoline lanterns and camp cook stoves that had to be pumped up the be pressurized. The lamps were so bright that you could not look directly at them. Thank you for this walk back in time.
5:20 There are "gasometers" in my train simulator. For years I could not figure out what these were or how to use them. After all these years, I finally know what one is.
Many interurban railroads were founded by coal gas companies in order to normalize a product of gasification of coal: electricity. If you could ride an electric interurban from Elgin to Chicago, you could safely put electricity into your house.
We have quite a few still in the UK - no longer operational but the structures are still there. They're all slowly being taken down & redeveloped which is for the best, but it is a shame to see the structures go
Which simulator do you use?
@@markwilliams2620 And now a good part of the former Elgin route is the Robert McClory and Skokie Valley bike trails. It was a lighter grade of rail than what Metra uses which is shared with freight.
@@roseroserose588 the redevelopment may be premature... if we are serious about moving to renewable gas they would be very useful.
The modern gas holder has a membrane inside an outer dome. The outer dome is inflated by air (like a bouncy castle) and always looks the same. The gas bag inside inflates and deflates with the gas level. If there's a gas leak, you can detect it in the "overflow" air of the outer dome.
So I did a ton of undergrad research into lanthanides like the yttrium used in that mantle and I can say there is no catalytic reaction going on. What is happening is just that the correct fuel to air ratio is occurring and a non dirty flame is happening. That dirty kerosene smell that comes from the Dietz lamps is due to the candle not being able to burn hot enough with enough air to actually burn all the fuel. The aladdin lamp is providing both enough airflow and draft that the flame can get hot enough to burn cleanly.
Check out the brain on Kelsey!

@@Biggles732 No. Acetylene burning in air gives a very yellow, VERY sooty flame. Which is quite nice - we used to use them for caving, under the nickname of "stinkies". (The calcium carbide used to generate the acetylene often had traces of calcium phosphide, which produced phosphine gas and a very distinctive smell.)
You are probably thinking of burning a mixture of acetylene gas pre-mixed with oxygen before being fed into the burner. Two gas bottles (or a generator and an air pump) feeding two hoses in one burner. Which *does* produce a bright blue flame.
I was blown away 20-30 years ago, taking the family camping, I picked up a Coleman propane lantern and had to figure out how to tie those little mesh bags onto the pipes.

ain't yet watched entire video... Those mantles represent the first commercial use of rare earth elements/lanthanides . A number of the rare earth elements glow brightly at reasonably achieved temperature. Cerium and thorium especially I remember. Thorium was the best performer and no longer used today . A fresh mantle is a cloth impregnated with nitrates of the rare earths and a silicon based chemical perhaps ammonium silicate. After commissioning by burning the installed mantle in situ, the ammonium and nitrate components and cloth cellulose are volatiled away leaving the rare earth oxides within a newly formed silicate solid structure that has formed in the matrix of the previous cloth fabric with some 40% shrinkage .

22:15 the part where it shows how the carbon gets "cleaned" by burning it away was really cool.
Yeah, that part was fascinating and beautiful at the same time. Quite pleasing to see up close.
It is real similar to "burning out the carbon". This was a technique used in the 1940s thru 1970s to improve automobile performance and mileage. Slow driving results in low engine temps, which led to carbon build-up on valves and seats, thereby causing incomplete sealing and poor performance. Occasionally , we would take the car out to a straight stretch of road and drive as hard and fast as possible. This would burn the carbon build up off the valves, and the car would run better. The proof was all the black smoke that would roll out the tail pipes during the first run. And for all the smart alecks, who are going to say THAT was oil leaking around the valve seals? You're just wrong, and obviously too young to have "been there". And too sure of your own, obviously inadequate knowledge. I was there, being now 72yo, and I also have a Masters in Mechanical Engineering.
Here’s another interesting connection. When electric lighting was first being installed in buildings, they already had a route to run the wires: the gas pipes. The electric fixtures went up right where the gas fixtures had been, and the wires were pulled through the pipes that were already there. This way, electric conduit was “invented”.
ah! I didnt know that!
Source? If you've pulled wires through actual conduit you know how hard even that is. Pulling wires through gas pipe seems almost impossible; the elbows are too sharp and the pipe has most likely not been reamed at the ends. I call BS
@@pasad335 Thanks for the reply. I don’t recall the source; sorry.
You make a good point. I bet that the insulation could get stripped as the wire went a joint where the pipe ends were not reamed.
But still, it could have been how the practice got started. Then, subsequently, people figured that they needed to have tubing that is more suitable for wire; curvy bends and free of sharp edges.
One source: the Wikipedia article on electric conduit.
@@davidkantor7978 Yeah, interesting. I'm guessing some of the early gas piping was probably bent brass tubing. That could certainly work as electrical conduit.
IN the 1960s, there were power strikes in the UK for three hours at a time. I was staying with my aunt in London at the time, in an old house which still had working gas fittings in some rooms, although they'd not been used since the 1930s, when electricity had been installed. With some difficulty, I found a shop still selling gas mantles and fitting them enabled us to continue with gas lighting during the power cuts. It was a pity that the TV wasn't a gas one, too, but we did have a battery-operated radio!
1972, not the 1960s. I remember coming home from school, unlocking the front door and lighting the candle sitting on the table behind the door. It destroyed the Heath government and the next two general elections brought in a Labour administration until 1979. And I was a volunteer election worker in all those elections.
The power workers weren't on strike - it was the coal miners.
Now only a couple of percent - often less - of the country's electricity comes from burning coal. Because Thatcher (hawk, spit!) hated the miners.

I’m fascinated by anything which burns kerosene for energy, I have fridges, irons, stoves, heaters, but my favourite collection is over 200 Aladdin lamps from model 1 which was a brass body lamp through to the current glass models.
Here in Australia Aladdin revolutionised kerosene lighting with their mantle lamps for all the reasons you’ve mentioned and Aladdin lamps are still used in some Outback locations today. Electricity is sometimes impractical to supply to extremely remote locations, so kerosene is still popular, it’s cheap, can be easily bulk stored, more easily than propane, and it doesn’t need wind or sun to run, plus the non pressurised Aladdins are silent. Aladdins are expensive though, even today, particularly some of the rarer models collectors are interested in. My mother told me when she was a young girl growing up on the farm with no electricity and only kerosene wick lamps and candles for lighting, only rich folk could afford an Aladdin lamp!
Love the show.
PS I’ve spent hours trying to get Aladdin burners to burn more evenly, it’s almost impossible, particularly model 23’s. I like your theory about wick thickness inconsistency, never looked at that closely.

I was born in a farm cottage that was lit with “Aladdin” lamps (mid-1950s)…if I remember correctly my dad converted a couple into electric table lamps (these were ones with metal fuel tanks, so he drilled holes in them to run cables). They even had lampshades because the original light from the mantle was so white and harsh.
Farm cottage , Yorkshire 1950s, great comfort in light & heat , also for carrying around the lambing fields ! The mantles were very fragile , like ash , and the light significantly brighter & more useful than a simple flame, The heat emitted was significant, but heated the room , and I think that some were adapted to heating a small cooking pan.

If we are being pedantic a Gasometer was actually capable of measuring the volume of gas by virtue of measuring its radius and its height.

Gasometers were a part of my childhood (and deserve an episode of their own). They were everywhere in those days (50s and 60s) and you could while away hours and hours 'watching' them rise and fall (much like clocks, you knew they were doing it, but could never actually see them move!). The sections were sealed with water (or rather the lower sections were stored in a circular trench of water), so when they were full, the top section looked OK, but the lower sections got progressively more rusty. We had an old disused one outside our flat until quite recently (early 2000s), and I've not seen any others locally since it was dismantled, so it must have been one of the very last ones still standing. Although they were, of course, used for storing gas, their main use was to maintain a steady pressure in the gas main. A very simple answer to a very tricky problem.
Interesting... so in a way they did "measure" something. Not just the amount of gas currently inside, but also the relationship between the generation and usage rates.

What wonderful memories this brought back to me! My maternal grandparents lived in a stone cottage in rural North Wales and, in the 1950s, had no electricity. It was so restful sitting in the "living room" in the winter, with the coal range and an Aladdin lamp on the table producing enough light to read by even if not at the table. Even though the fire was usually kept low to save coal, unless you were boiling a kettle or baking in the small oven built into the range, the room was indeed kept warm by the heat from the Aladdin lamp.
At bedtime, you used an old-fashioned candle holder to walk down the narrow passageway to the bedroom, where it was much colder, and the candle was put out as soon as you were in bed, leaving you in total darkness.
I would not be upset if I was forced to live like that again, especially in such a beautiful part of Wales.
Same here, in NW Scotland, we only got connected to the grid in 1979 I believe. Great memories of the gentle hiss of a Tilly Lantern, and the incredible ,soft light that they produced. I am seriously considering going off grid again now, it’s funny how everything comes around…. I can still remember the smells of paraffin and methylated spirit- I was fascinated by the beautiful purple colour as a kid! 👌
@@supertramp6011 You couldn't afford the paraffin for the Tilly lamp. Near £12 for a 4 litre container locally in Ayrshire.
@@ianfraser8347 dang, that’s crazy! £3 a litre? What’s up with that?🤔
My Grandparents had a cottage on an island from the 80's up to the early 2000's. Up until about '95, the whole place was powered with propane. Lights, stove, even the fridge, all propane powered. The water was pumped from the lake with a gasoline powered pump to a small water tower.
After the electric upgrade (which would be wildly expensive today), the stove remained propane, and one light, in a little corner with a comfy chair, and a perfect view of the lake, the perfect spot to curl up with a book, was left alone, it still works.
I notice that the "ties" that attach the mantles are now wire. They used to be asbestos string.
Mmh, cancer spahetti - tasty
Well if your mantle is going to contain a radioactive isotope you might as well add asbestos, because the customer is getting cancer anyway.
You can get them with string or wire. I still use string.
Thorium and asbestos. The past was a dangerous time
Asbestos is still in very wide use today in the US. It is just not used in residential settings, only certain industrial uses. And it is no more of an issue than gasoline is. Asbestos is perfectly fine as long as you don't create dust. Gasoline is perfectly fine as long as you don't let it create vapor.
When I grew up the gasometers in the local town were quite visible and they had scales up the side so you could tell how much gas was in them so they were in affect measuring devices.
When the centre is high the container is full as the contents is used the container falls, the weight of the container pushing against the gas inside giving gas pressure in the pipes.
For anyone in Aus born before 1970 gasometers should not be a mystery.
Given that , even without measurements on the side, it's possible to gauge the amount of gas held at any time, "gasometer" is the most appropriate name for them.
Two massive units were astride the 405 Freeway in Long Beach, California -- for years.
They eventually became buffers for the adjacent refinery -- IIRC.
This was the same refinery that Cody Jarrett blew up in "White Heat."
He was atop spherical propane-butane tanks... a bad place to smoke.
They must be gone by now -- so old -- and sitting atop valuable land.
Occasionally a gasometer would blow up. I remember one did so in Copenhagen in the seventies causing great damage as domestic housing was built much too close.
This was the first experiment I taught to my Introductory Physical Science classes. Wood splints were heated in a test tube retort and it was observed that a new solid (charcoal), a flammable liquid (wood alcohol) and a flammable gas was produced. The wood could be decomposed into new substances, but not put back together. A great experiment raising many questions.
In my encounter with that as a student, the teacher used a cigarette instead of a wood splint. The stuff that came out of that served to make me a lifelong non-smoker.
Interesting and informative video. I remember many years ago having a Coleman lamp with the bag shaped mantles like at 17 minutes. When new, you had to burn off some material that was blue if my memory serves me right. After that, they worked well, putting out a lot of light. The fuel it used was naptha.
You beat me to it by a day - 1 year after the video came out...!
I still have a couple my parents used when camping, when I was a kid. They still work but I always start them outdoors.
I have two of those old Colman lanterns. My dad bought them back in the 60's.
They are pressurised lamps
Some mantles (Coleman) are thoriated, meaning they are treated with thorium and are radioactive. The thorium increases the brightness.
The "Dietz nutz" joke from the previous episode still kills me
i still get a chuckle
@@technopoptart every time he says "Deitz" I start laughing.
I was trapped in a Las Vegas jail cell in Quarantine isolation with the Deez Nuts guy from Vine for 72 hours.
Now I don’t ever want to get famous
I remember the Thorium nets. We had a lamp with one when I was a kid and used it on all our camping trips. My father, then a physics teacher, had access to a Geiger counter and just for giggles he brought it home and pointed it at the lamp. The noise that followed was quite scary. We didn’t stop using it though. Different times. 😳
Yep! My dad would sometimes bring us to his cabin near his little hobby apiary. There was no running water or electricity, so we'd use this kind of lamp with a propane bottle. I was very fascinated by the glowing fabric and he'd always tell me to not touch the mantle, said that it'll give me cancer. That was 15 years ago.
My dad was a doctor. We lived in the south and the mosquitoes were fierce. Back then, mosquito repellents weren't very effective. He made a mosquito repellent that worked perfectly. Just apply it liberally all over your body and you never got a single bite. It was kerosene and sevin mixed together. Amazingly, I'm still alive and in good health. He was quite aware of the risks but insisted that it was still healthier than getting 100s of bites every day.
Thorium goes through alpha decay, so it's not that dangerous as long as it's outside of your body. It becomes dangerous when you accidentally inhale or swallow the radioactive dust particles, which is a real possibility with a mantle.
It's notTHAT dangerous for the user, as long as you don't let the pieces of the mantle get into you (harder than it sounds, as it's basically ash, but not that hard...)
It's the manufacturing (especially back when nobody knew anything about radioactivity, and dumped thorium waste like it's nothing) that's the real trouble. Some of the old gas mantle plant sites are still being decontaminated.
Back in the day (the 1970s), we went camping with a Coleman lantern that had two of what we always called 'booties', and I remember they were considered to be VERY fragile and at the time I remembered them to be radioactive in some way.
When I was younger, the Coleman lantern was the choice for camp lighting. I recall a 21 year old intoxicated me grabbing a Coleman that "brewed up" in a friend's camp and setting it on a rock ledge outside where it could burn itself out safely.
It was a fun stay. Later that night we watched FB-111'S flying in and out of Plattsburgh AFB 20 miles away. The next morning, we were all recovering from the night before... eating eggs and rabbit hash out on the ledge when an A-10 flew up the valley. We were looking down at the pilot, who saw us waving and waggled his wings. Good times.
These lantern videos really brighten my days
2:18 Fun fact, that letter would have been written while there were still indepedent Maya city-states. The last one to fall to Spanish campaigns only did so in 1697, 6 years later. I wish I could provide an additional tangent that ties Mesoamerican civilizations into the topic of the video, but sadly there is no extremely clever pre-European adaption of fossil fuels for lighting in Mesoamerica, though if we're talking about things like sanitation/hygine practices and processes, medical, botanical, and agricultural science, etc, I can think of a number of examples. If you ever cover toilets, dyes recycled from human waste, gardening, aquaculture, herbal remedies, Nixtamalization, cements, surgical rods for setting bones, etc, I'll have a lot to talk about!
there is some evidence China in the Spring and Autumn period (771-476 BCE) used natural gas for lighting and heating, though, with bamboo pipes!
Make some videos. I'd love to hear all about it.
@@noalear I have, sort of: I don't have any on my channel, but I've acted as a consultant for a few other channels, like Invicta History's Aztec rank video, Cartoon Universe's video on Onyx Equinox's Mesoamerican influences, and Ancient America's video on Teotihuacan. I also do long essay content on other websites, and retweet and reply to a lot of historical stuff on twiter (I'm @Majora__Z there)
There are also the legends of El Dorado or similar, where IIRC, explorers broke into chambers and/or tunnels and observed lighting that they assumed must have been burning for several centuries (since they were the first ones to have been in there in a while).
“and we'll cover that in the next video”
Damn cliffhanger endings
As a collector and restorer of old Coleman lamps it was a sad cliffhanger indeed.
@@Juggernath I stil have my familys old pump lantern.
My dad took me gigging with a tilley back in the day. Then I took it up with my friends using a gas lamp. Then a halogen H4 and a car battery. Now you could probably just use a key chain LED.
Next up Tilley lamps...
I've watched too many Morrowind memes and thought that said cliffracer
"someone asked for a simulated hurricane, I can't do that but"

Lol I love this series, it's just the right amount of comical built into a very informative package to me.
I was expecting (hoping?) the lantern would slide out of frame. No no nonono.
I was hoping to see the leaf blower used on the Aladdin lamp.
I use a Coleman "white gas" lamp while camping. I grew up around these lamps. I remember my dad taking the lamp and pumping it to pressurize the tank. My dad used to pull out the mantle after the old one would get a hole.
"He called it a gasometer."
That name annoys me.
"This name annoyed scientists."
I'm a scientist, confirmed.
I like the word gazomètre because the height of the cover actually gives a visible measure of how much gaz is in stock. And also because I'm french and this word looks far more french to me than gazofeet or gazoyard
We had a gasometer near us. The cylinder floats in water to make a seal. The more gas you have the higher the cylinder. This maintained a level pressure so I would say it could be classed as a Meter as it gave you a visual indication of how much gas you had left.
Samesies
We are all scientists on this blessed day.
I used to work in gas utilities. The gasholder / gasometer is dual function (although we referred to the locations as holder stations), town gas was produced around the clock and natural gas is transported likewise.
So local storage during low demand was needed as they function at relatively low pressure. Also release gas to the system during high demand, regulating pressure. They have become largely obsolete as the supergrid network can be over pressured for storage and exhausted gas fields can be re stocked. Yes putting gas back underground is a thing.
I love how you lampshade and foreshadow what's coming next.
Cool video. When I was in the Canadian Forces from 1980 -1997and I was posted to Comox BC in 1991, one of my secondary duties was as a member of the Nuclear Emergency Response Team (NERT). When training with the equipment to used to detect and locate radioactive material, we used live Radioactive material and of course a much safer training material. That training material was the new (unburnt) Coleman mantels for the lantern which worked well as a training aid.
I bought my Aladdin lamp at a local hardware store about 15 years ago. I had been using propane fired gas lights in an older camping trailer and wanted the option of using a kerosene source. My brother had used an Aladdin lamp in his home 40 years ago which had a fixture which would allow him to hold a pan for cooking above the lamp. That provided an increase in efficiency, light and cooking, and enough heat to take the chill off the cabin on cool, but not too cold, nights. We had used Coleman lanterns fueled by white gas back in the 1950's, so we have used all 3 types of incandescent mantle lamps over the years. Although I still have all these lanterns, the great improvement in efficiency of LED lights and rechargeable batteries may mean that they will just be relics on the shelf as curiosities. This presentation provided some interesting history and details I had not been aware of.
"forced my lute" lute was for sealing and fireproofing different components in chemistry. He may be saying it caused enough overpressure to break the seal been the retort and... Something else
u might be right. a top-voted comment, meanwhile elevated to the top of this comment-section, gives a similar explanation.
I run an isotope handling course at a university, one of my props (among many) to demonstrate the response of the contamination monitor is a thoriated gas mantle. They certainly send the Geiger tubes crackling.
Thank you for explaining how my dad's old camp light worked. I swear, seeing the tiny mesh light up that brightly was basically sorcery.
I used to opposite a set of large gasometers in the UK and they were really useful to know what the weather was going to be like.
If they were full, you knew cold weather was on the way because they were building reserves for the local gas heating
I guess in that way they were good for measuring things
As a technician, I was drawn here by the title and I found the content very informative and interesting. What fascinated me most is your use of and skill in English language. Not too common for a person covering this type of a topic. A master orator.
Agree he is a great presenter
What fascinates me is seeing a comment like yours. I find his style of presentation so grating that I quit the clip two minutes in, even though the topic's quite interesting. I have a severe aversion to the cheap gimmick of pretending that ideas are taking the speaker by surprise when it's obvious that they aren't; e.g., his way of mentioning that _retort_ doesn't mean another sense of the word, etc. It reminds me of a typical script from _Friends,_ i.e., makes me want to puke. Okay, it just makes me shudder, but either way, I don't watch anything presented in that style... and SpewTube is infested with it. Anyway, he's the very opposite of a master orator.

Extremely interesting. Really appreciate bridging the gaps leading up to electric light. Your research and presentation ability, attention to detail and admission of imperfection in knowledge in some rare but understandable cases make your videos a true pleasure to watch. It amazes me how curious you are about such a wide range of topics.
Some of my fondest memories from childhood are watching my dad change the mantles on our Coleman lantern before heading out to 'the land' for a hunting weekend. And then the gurgling hiss of the lantern lighting up our entire campsite from pitch black. Good times.
The steel mill that I work harvests the various byproducts from the coke ovens, including coal gas. They actually use the coal gas as fuel for the coke ovens themselves, as well as various other things like boilers.
Same with the mill i work at
OK, but why would you bake soda? Personally, I find it better cold.
@@BodyMusicification groan
Unless it's baking soda of course...
Best not to snort baking soda mistaking it for coke, however.
Gas lights is where we get the phrase “TURN the light on”. As you said, there were valves; not switches. Thus, you really don’t “turn” on an electric light, but the term had been established and just stuck.
The early electric light switches were also rotary…
@@allangibson2408 Because they were just repurposed gas valves.
@@erinfinn2273 No - electric switches and gas valves are wildly different. The designers wanted to maintain familiarity however.
Wiring was however run through the old gas pipes - which is why American electrical conduit still uses pressure tight threads.
The other power source in most cities was water - the hydraulic power systems continued in service until the 1960’s running lifts. The hydraulic power pipes in London were repurposed in the 1980’s for fibre optic cable runs.
@@allangibson2408 I guess what I meant was that the interface was just repurposed. I do know the mechanical differences between gas and electric switches. You just said what I wanted to say clearer.
Edit: I made that post when I was very tired. I mean no disrespect to anyone's intellect. Also, didn't know about the municipal hydraulics system. That's cool.

You've done it again! This is the second video of TC that I've watched and like the first, it is so entertaining and educational, both at the same time. You're such a natural explainer of complicated things.
I do appreciate more and more the cleverclogs concept of the mantle, and the entertainment factor of alarming people with a roaring geiger counter never gets old, I still forever associate them with the seared-in memory of being utterly blinded by that hissing nightmare on camping trips. "Enjoying all those stars? Here lets light up the GODDAMN SUN right at eye level"
indeed. In boy scouts, they had them on long poles attached to propane tanks like you'd find in a gas grill. And they had 5 of them for the main area, obliterating your night vision so you'd find every ankle-busting root on the way back to your tent....
The end was disturbing, the rest was lit.
You take my thumbs up and get the heck out of here... good day sir!
Slow clap!!!!
you're not wrong!
In my early 1900's built house, they literally pulled two wires through the gas light pipes when they converted the room lighting to electric.
That's interesting. I had a house in Scotland that still had some old lead gas pipes in the walls for lighting but they were only about 1/4" inside diameter.
This was true of a lot of street lighting, too, at least in London.
@@Phiyedough Yes... our house in Los Angeles was built in 1914 and had gas light fittings in every room. Electrical wiring was installed later, obviously. As a young kid, I wondered why the gas outlets were so high. Of course, they were for gas lamps. The house is still there and probably still has the hidden gas pipes running through every room (of course, empty).
Well, guess that's one way to retrofit knob and tube wiring lmao
I have a lamp which was originally a gas lamp. It was converted to electric and the wiring runs through the remaining gas fitting on the base of the lamp. Had my brother (owns hundreds of kerosene lamps) not told me, I would never had known it wasn't originally electric.
I like seeing how things are invented and created. And it just shows people new how to do it from way before they just never pressed on to actually master it and obtain utility.
That is why I believe we are more advanced than we think, and we need to discover less and tie more ends to get what we want.
Speaking of town gas, I'm just old enough to remember the giant gasometers in St. Louis. They were these huge tanks that looked like cylindrical cages with a large balloon that filled up and down according to supply and demand. I always thought they were super cool!
They removed thorium from lantern mantles?! How's a boy scout supposed to make a breeder reactor now?
the older thorium mantles are brighter and tend to be more durable...that's the controversy.
you laugh, but old gas mantles are also used in radiological event training as samples of radioactive material.
“Forced my Lute” sounds like a good euphemism for “blew my mind”
Yeah I'd like to blow his mind. 🥰
I mean, that isn't too far off. It was more of a "blew off my rubber hosing" thing, but the implied pressire of the flammable gas in question is pretty applicable.
Blew a gasket
I just posted a comment on this, I think he might be using a lost euphemism for sneezing. (something strummed him and he put forth sound). Like the classic cartoon honk sneeze, along those lines. People where I *think more clever with language and writing in earlier times. Qualifier: I'm no expert
Fascinating stuff. As an old man now (b. 1954), I have seen some of this technology in use, and heard more about it from my father. When on holiday in caravans, we would use gas lighting with mantles. They tended to burn brighter the longer they burned, so you had to reduce the gas flow after a while. Eventually, the fragile ash mantle would fail, either due to the carbonisation you mention or because vibration in the caravan would fracture it. My father was raised in a house where the only source of lighting came from 'fish tail' gas lights. He took a candle with him when he went to bed.
Your video was so much fun. I'm 66 and originally from the UK. When I was 5 my parents were really poor and we lived for a few years in an uncle's holiday cottage that didn't have electricity, so it was illuminated with gas mantles everywhere. This was before the advent of Methane/Natural Gas. One of the fun things you forgot to mention is that coal gas is heavier than air. So in the winter and if your house was sealed really well it could asphyxiate you and if you woke up and lit a candle it would blow the house and you to smithereens (lovely word). It had a distinctive smell much like essence of old engine oil, My parents reinforced the rule in both my sister and me that if we smelt it we were to yell and run outside. The only problem was that we always could smell it.
I can't wait for your next video and I'm assuming you have a Tilley lamp in the video. I have two for our power failure kit because they are staggeringly bright and only a bit explosive. They can run on all the kerosene derivatives (Jet A1 works particularly well) although red diesel seems to gunk up the tubes after a while. You would have to be mad to run a pressure vapour lamp on gasoline so I bought one of Coleman lamps but it definitely make me itch when it's running. The Tilley lamp is hilarious because you usually set fire to a small bath under the mantle of methylated spirits to pre-heat the lamp to get it up to temperature. Once it gets going though it's so bright you can illuminate a whole campsite.
In Vienna there where some big "gasometer"'s that are now repurposed, but when they where holding has you could tell by how high or low the containers held by the structure where how full they where
I believe there are some in London that have been converted to fancy apartments
As he said gasometer i instantly thought of the eventhall or what ever it is, called "wiener gasometer" in vienna.
@@alexe8375 well, the frames were moved to the other side of the canal and fancy apartments were built inside them. The material that actually held the gas was far too toxic to reuse.
There existed in my city, a gasometer, until about 10years ago. It was a 'listed' building. It was not actually in use. Then they decided to use the land for a supermarket. The telescopic dome floated on water which acted as a seal, and it expanded as gas was added.
there was one in my city that they tore down in 2013
I've used an Aladdin lamp for Years! On the northern California coast the closest electricity was miles away it gave off the equivalent light to a 90 Watt bulb plus it gives odd some heat that helped heat A slightly drafty cabin.
Bonus: you can toast Smores three feet above the chimney!
Regarding the statement “these sorts of lamps can’t be used outdoors”, I lived in Houston TX in the early 2000’s and most homes in the neighborhood had filament style gas lanterns outside in the front yard lighting the path to the door. They were on 24 hours a day which I thought was terribly wasteful of gas. I accidentally severed the gas supply line with the lawnmower and the light went out. For the next 4 years I left the gas supply turned off, only re-lighting it when it was time to sell the home.
"That's terrifying."
Not as terrifying as when you *_tipped over a kerosene lamp in your home._*

Just buy Russian mantles
I was especially excited for this episode. My parents used to take us camping when we were young and we had one of those propane-bottle & wick lamps. It was always this mystical beast, being a combination of very powerful but also quite fragile. I was very excited to finally learn how it all worked.
Where I live we have naphtha lanterns for camping, I remember asking "what happens if we touch the wick while it's on?" The answer I got was "not only will you disintegrate the wick, but you'll also severely burn your finger."
I remember camping as a child in the 80s, and our propane lamps had a single wick in the middle, and a portable propane cylinder underneath. Larger than the one in the video, but smaller than a BBQ gas bottle.
I have both propane and gas lanterns. I mainly use the propane lantern though. I just bought a tree to put on my 20lb tank that the lantern can sit on top. Much cheaper to refill the 20lb tank than keep buying the little 1lb canisters plus the tree lets me connect my propane stove to it too. I also have an old 3 burner gas stove that has the propane conversion kit, which is just a pipe with a threaded end for the propane to connect to. Nothing else had to be changed other than to remove the gas tank.
@@jasonantes9500 So confusing reading the word gas in this context. My use of it was as a synonym for propane/butane, aka liquefied petroleum gas, LPG for short.
We (Australia) understand the abbreviation gas for gasoline, in context with American cars, but our cars that run on gas use LPG or autogas.
So my BBQ gas bottle referred to above was an 8.5kg LPG cylinder.
@@jemsterr Yeah, different parts of the world different vernacular. Yes, my use of gas is short for gasoline. I could have said dual fuel too I suppose. Anyway, cheers!
Thank you...I now understand what this gas mantle "thing" is. I encountered it as a concept for the first time today, and once I saw what new ones, ready to be used, look like, I was very confused as to how a fabric net bag became a helpful and desirable item once subjected to flame. GOT IT NOW. Much thanks, no more confusion. Very clever invention to improve the usability of the then-available technology.
Can you imagine people being smart and careful enough to use this in their homes now? Drivers have trouble nowadays simply remembering to turn the headlights on for their cars at night...
This is the first time I've ever heard or read the name "Auer von Welsbach" from anyone outside of Austria. He did a crazy amount of different stuff, I can only recommend everyone to give it a read. I happened to go to school with one of his descendents (not into chemistry himself of course, but kind of cool).
Oh, and he used a Bunsen burner for his lamp because he was literally a student of the man it's named after. He's also the original founder of Osram.
I know right, he was clearly pretty creative and contributed to many different fields like literally discovering a new element (Lutetium). Though, like you said, almost nobody seems to remember him now and somehow he almost vanished for good.
@@yeet1337
Regional bias to some degree? Like, US-Americans are crazy about Edison and Ford yet don't care about A. Volta or Carl Benz.
@@Alias_Anybody Yes probably, but even in Austria almost noone ever heard his name today.
Echt interessant, hab mich grad etwas über ihn erkundigt und es ist tatsächlich sehr seltsam dass ich wie die meisten noch nie was von ihm gehört habe. Vielleicht war das aber auch seine Intention? Oder er wurde einfach vergessen :P
Wobei ich den Begriff "Auermetall" schon häufiger gehört hab, wusste aber gar nicht dass es nach ihm benannt wurde.
Hahaha und der Wikipedia Artikel über ihn beinhaltet: "Selbst war Auer die Personifizierung eines Forschers und Gelehrten, - ein systematischer und disziplinierter Arbeiter, der sparsam mit Worten und schriftlichen Aussagen war." Da scheint ihn ja jemand sehr zu mögen :D
The story that I have read is that Auer von Welsbach invented the gas mantle partly by accident. He was trying to separate and identify the different rare-earth metals and was boiling a solution of rare-earth salts in a flask that was standing on an asbestos mat over a Bunsen burner. Some of the solution boiled over and spilled onto the red-hot asbestos mat, and when it dried out it glowed brilliantly. Welsbach developed the gas mantle from this accidental discovery.

"No, that was correct, why did you stop" has to be one of the best outtakes I have ever heard
I grew up using those Coleman propane lanterns while camping. Fascinating to learn about the technology because it made no sense to me as a kid. I just couldn't wrap my head around how putting a tiny sock in the lantern made it so much brighter.
I hope this series continues onto safety lanterns used in mining for some years. I believe they have a 'flame arrester' to prevent them from causing explosions.
Now you're wandering into Davy lamps.
Early carbide fueled miners lamps basically produced and burned acetylene
they basically had a fine mesh that when the methane entered through it into the lamp it would safely burn without spreading the flame outside of the lamp. I'm not so sure on the physics of why that occurs but it does.
@@A.Martin It was demonstrated at the Royal Institute by Humphry David who invented the lamp. The way it works is that the screen is small enough to let combustion gasses through but not the flame front. The original filter was a bundle of tiny tubes that formed the screen which cooled the flame front to below combustion temperature so no flame could progress to other side of the filter. Think of a bundle of drinking straws but shrunk down by 80% and made out of brass. It was eventually refined by using a stack of woven brass screens with fine brass wire and each screen was spaced about a quarter of an inch apart. If you look at a miners lamp there's a large collar that looks like a hood above the light glass. The filter is housed in that hood.
