U should try coconut shells to burn to increase the temperature
Maybe try bamboo for the pipe
For the wood you can chop down a norway maple tree, Norway maples are invasive trees so you can save money and help the ecosystem at the same time
140 bucks for wood sounds steep. try craigslist for free local sources.
Will you do a canon
Hi. I'm a retired ceramic engineer. Use charcoal instead of wood. Form a thick layer of silica sand in the front center of the furnace. Make a depression in the center of the sand to form a bowl. Put your premixed ingredients in the depression. The pure silica sandmelts at a much higher temperature so you will end up with a pool of melt that is more fluid in the middle and will fork its own solid bowl. Draw from the fluid portion. Build the charcoal fire to each side of the pool. Good luck. I enjoy your efforts and they show just how much practice is needed to get things right.
So nice to hear reference of the King of Random's Grant, he will be missed
I think you ment "King" instead of "Kind."
@@benkayvfalsifier3817 Edited, cheers!
@@Hughsie28 back when king of random was good, rest in piece grant
@@bigbird4481 Callie and Nate were fine IMO, the new people they added are corny asr it turned into more of a kid channel
What happened to him
Andy falling into the water and andy lighting his backyard on fire gets me every time 😂
It hurt more than expected to see Grant again. I really hope his family is doing ok ❤
Damn his kids are going to grow up without their father. They were so young, I bet it was hard to explain.
I'm out of the loop on this, what happened?
@@leakingamps2050 paragliding accident like 2 years ago now
@@Falcodrin Damn, it was that long ago?
Forever may he rest in peace the man was a legend I also hope his family is able to carry on in a healthy manner
Still miss Grant :(
Me too
yep
RIP he will not be forgotten.
Ye
TKOR is not the same since he passed away 😔
I can’t wait till you get to the point where you build your first metal lathe and mill. Then eventually you will have to design and develop machinery to make your own vacuum tubes and then transistors. By the end you will be able to make anything and everything.
He will need to stop half assing things first.
@@ImCannibalOfficial Yup, but he's not yet at the point where half assing is all that bad :)
@@ImCannibalOfficial true, he takes about a month for most videos but I think the biggest problem is that people got bored with his lack of progress made like when it takes a month for a video and he just makes a burger... yay can’t believe I waited a month for that... and because it’s boring he loses views making less money and he can’t do this full time
@@Hi_Brien I mean if he were actually trying to do anything with the things he’s made long term as people would have had to at the time it would have been a bad thing. It’s just a fun proof of concept though so it’s fine.
Even if it the series isn’t strictly trying to stick to its rules in a way that makes sense it still feels like this channel ought to get more views for how much time, work, and money they put into it even if they do produce low quality crafts in the end.
Part of the problem with the quality of his items is that he previously hasn't been consulting craftsmen for each specialty, and in the few instances he has consulted experts, their input is largely ignored. (Or in the case where a "bow" was made, in idiot was consulted.) At the current level of tech, he should already have hardened files and carbon crucible steel for making tools to make the correct tools for all this work. Skipping steps in the tech is why all his work looks like a 6 year old made it with their feet.
I'm glad to see Andy's old nemesis is back - glass!
Man seeing grant made me shed a tear. I remember watching him in elementary school. RIP
He really didn't need to remind us. completely unnecessary to open old wounds
If I am not mistaken, can't you reach higher temperatures more easily and with a cleaner heat using charcoal instead of wood?
think so too
that was one of the reasons why they chopped down the forest that existed before the black forest (it got its name from the excessiv use of needle woods for its reforestation since its fast growing wood, which could be used relativly soon), they made ALOT of charcoal for smelting iron from ore.
indeed you can, primitive tech channel has videos on him making charcoal kilns
This is correct. In fact, it went wood > bituminous coal > anthracitic coal > charcoal >= coal coke, in general.
try woodgas
@@firebladeentertainment5739 the Black Forest actually got its name from it being a rather dangerous place to be, the darker spruce trees came after the name
People don’t realize how much effort it takes to make glass.
Yes indeed
You now have Cullet, a key ingredient in glass making. It will reduce the amount of energy needed as already made glass is easier to melt than new glass.
They might be able to reach higher heat with better fuel, like charcoal
Exactly my thought. Would limit the smoke and soot as well
Or hard coal.
@@The_Mess85 I'm pretty sure you would want to still turn coal into coke to avoid introducing sulfur to the process (and to drive away volatiles)
Also more oxygen. If there is soot, it means he isn't burning all his fuel.
At first I thought it was Andy working with the clay, and that he picked a fun color of nail polish!
Man you haven't made any bling yet. Jewelery was huge amongst our even earliest ancestors.
hmm, good point :)
Good point, Andy could make a ring of each metal to prove mastery of it
Aliens are invading this video, they must love pottery work.
UFO at 5:39
I know right and not many seemed to of noticed I seen it and went straight to the comments to make sure I wasn’t seeing things
Yeah, aliens love pot.
I thought I was tripping when I saw that!
2:02 mentions Grant and King of Random but doesn't mention Cody and Cody'sLab. 😢
Still wish Grant was with us though.
Seeing an Alec Steele anvil makes me happy
Yes I was wondering if anyone else noticed it
This really shows how important cooperation was back in the day.
Indeed. Specially Bronze which required tin and copper, both being quite rare and heavily localized metals. Thats why civilizations have evolved differently and its just plain wrong to assume that any location in the world could have developed advanced societies.
Cooperation is still insanely important today
When Grant was brought up, I almost started shedding tears
im actually suprised that dude was able to turn that piece of metal into a somewhat smooth pipe
Man's made another failed glass video, I mean imma still watch lol
another testament to the fact that even though these technologies are black swans, they individually took lifetimes to master.
Ayyyyy it’s an Alec Steele anvil!!
I haven't watched anything yet, but I'm guessing the intro will be "We've tried to make glass multiple times. It is the holy grail of our channel! Let's see what goes wrong today!"
Lol
R.I.P grant
Fr I used to watch him all the time
@@tempt4tions412 Me to🖐️😢
Every episode with Adri instantly becomes twice as good
facts
It’s still so sad that grant died😢
Who was that
Who was that
@@TheDaken73 the original host/creator of king of random. He died from a paragliding accident.
Aww man, I still get a pang of bittersweet sadness whenever I see videos with Grant.
He truly was one of the TH-cam pioneers and such a kind, humble person. 😔❤️
Try using mullite crucibles. They're intended for this use case, and are a ceramic product, so they fit with your tech tree. They work great for both metal and glass casting.
I’m literally a Jack of all trades when it comes to crafts. I actually want to learn htm everything, too!
5:27 the walk of unmatched swagger
Frequent guest and probably my favorite guest, Adri!
Also I have no idea what's happening at 5:26 - 5:30 but I love it :D
To be completely honest, I also have no recollection of doing this.
@@TheElfsmith
Adri MVP again! I had no idea making a metal pipe like that was even possible. I would’ve thought you’d need a rod or something in the middle of that to set the forge welds without collapsing the entire pipe.
@@gavinli1368 I did, actually, it just didn't make it into the little short mashup as it wasn't very interesting.
Rest In Peace Grant
I've been waiting for this class, I'm excited to learn!!!!!
6:53 Never pour liquid accelerant onto a pile of loose brush.
A tip for candling . If you start with hot coals and place them evenly across the bottom you can control the heat much easier. Then add fuel generally in the form of either a hardwood or or more Charcoal. When using softwoods the excess of gas some sometimes reduces the heat due to the fact that the draft is greatly higher than needed. Remember for every cubic foot of air that goes into the Kiln extra over what is needed, needs to be heated up and evacuated. Try to use hard woods such as oak and Maple as they will allow for higher BTU put per cubic foot of material.
That blacksmithing was pretty good. Hitting it hard enough to fuse but not collapse, very well done.
This is really interesting seeing you think through this whole reset
Glad you've got Bright Cellars sponsoring you so you don't have to drink any more of that homebrew wine of yours.
You did it, Andy! A great achievement for you and the team. As always great video and awesome production quality. Keep up the good work!
There’s a kiln design called “the philosophers kiln” that is very efficient when it comes to firing with wood. I don’t believe the romans used that design but it will certainly get up to 2300 degrees with proper air flow and minimal insulation, also loving the glass/ ceramic section of this series!
loved the music, editing, and structure of this video. much easier to follow than the previous ones!
frankly, seeing you getting so much better at making things just in craft is almost as good as you showing how much better we as species have become with tech. youre so much more precise and detail oriented compared to a few years ago and it really shows in your products. What youre making is really good!
RIP king of random 🙏🏽
RIP 🪦 GRANT! Fly high
Put a little Bentonite clay (kitty litter) and add it to the runny borax, and it will thicken up. It doesn’t take very much either. It’s really easy to control the viscosity to your perfect consistency. Thank you for all your awesome content! Keep it coming!
Nice Steele envil!!
3:50 hell yeah a steele anvil!
5:39 lol caught me off guard
Rip Grant you taught me so.much in high-school you will be missed TK❤R
Rest in peace, Grant
Pretty cool to see a Steele anvil!
When she was throwing the clay, reminded me of ghost.
I don't know if Andy and the team will see this, but I thought I should write in anyway. A friend of mine in the viking reenactment community told me once that they would add ground up broken crucibles to the fresh clay when making new ones, so they would be stronger and withstand more heat. It might be worth trying out, since you seem to have a lot of spent crucibles.
this is incredible! fascinating process. thanks.
Watching this journey is incredible, to think it took 100s of years between every invention you’ve recreated
5:25 so you're really just going to gloss over The Walk huh Andy?
RIP Grant the true king of random
"sandwich" - albert einstein
He probably said something like that
I remember this
Borgir
hell yeah worth the wait
keep on doing what you are doing andy and team
Love the Steele anvil!
Amazing work !
rip grant, I miss his presence on YT :(
Awesome vid andy
This channel is awesome! i have always wondered how they used to make things that we use every day
1) While I'm a little disappointed that Andy isn't the one upping his skills and refining his tools as much, I'm still really happy that he's at least outsourcing the relevant work to professionals of the trade, because seriously, it takes years to master things like blacksmithing, not to mention all the tools and setup it takes to properly get going, so while it isn't *really* in the right format for The Reset in total, it's still a far cry better than before. Besides, when you think about it, it wasn't some master craftsman that did all the blacksmithing, woodcarving, brickmaking, baking, bladeshaping, etc. etc. etc. but various masters of the different crafts, though there was obviously little bits of overlap here and there, so the modern forge aside, this is way better.
2) "Bendable! Poseable! The Alien AKA the "Medium Green Man"! GLOWS in the DARK!" I was obsessed with finding a frame I could read that on, hahahaha. Made me laugh when I finally saw it. Thanks for the little bit of humour.
This dude deserves a lot more subs and views it is such good videos and honest work 👍 Andy 😀
This is a really neat channel. I always love seeing this kind of stuff.
Don’t move on till you have success. We will keep watching, you keep trying.
I see this mistake often on youtube, when people are trying to heat things up like this. People make these dinky, low mass kilns. You need mass to even out the heat, to hold it in, and to buffer (slow down) changes in temperature. The only reason modern, tiny, kilns work is because they have a freaking propane blower on them.
At a minimum, especially with glass, I'd have double layer brick, but I liked how he eventually added some weight. You want mass. Get some straight up KG's in there. Then there's a problem of getting hot enough. This is a challenge with primitive methods. Modern times you just add a leaf blower and stuff it full of wood, viola.
To do this in a primitive fashion, I think you need to make charcoal first. You'd need a mound of it. Then you should use a timed method to reach your temperature. IE: fill the chamber with charcoal, burn half it it, time this, say 10 minutes. Then on the regular top off the firebox. Consistency is key. You'd probably wanna add a blower somewhere in there if you can. Blowers are discussed elsewhere on his channel, but for the love of god man. Make it bigger ;P
Thx for sharing you glass journey:)
Nice Steele anvil Adri's got.
🔥🔨 love it
2:03 R.I.P Grant Thompson
That's a very nice Alec Steele anvil that your eleven blacksmith is working on. LOL
You guys are amazing.
You are an inspiration
Love it!!!
RIP grant. The true legend of TH-cam
The return of the elven smith
Rest in piece to the absolute king of random
I litterally watched grant since about his tenth upload ever when I was a little kis, it was nice seeing him again.
Grants glass video is how i discovered your chanel he will be missed
🥲 Rest in peace, Grant
Maybe with a way to pump Air in the furnace and coal you might be able to get higher temperatures
He had a big electric fan pumping air through it, i can't remember him building it though
Find a bunch of primitive natives and introduce them to Ramen in exchange for pumping allot of oxygen into you furnace its quite simple actually👌
This really puts into perspective the fact that Galileo made a telescope in the 15th century. Well done!
I was wondering what happened to you. Glad you are still committed to making grate videos of science!
try Roman concrete to mortar the bricks to improve heat retention
Look back a few episodes. The bricks are a modern ceramic brick adequate and appropriate for kilns since he did Roman concrete already.
Very nice!
Seeing Grant made me sad. Damn, he was such a good guy.
Maybe you need to add a large bellows to force more air into the combustion?
How to make everything up to modern times. Let me know when the nuclear power plant from scratch series will be. I need a small one for my back yard. Hehe.
I want him to go forward into the future: I urgently need plans for a nice small fusion-reactor for my backyard ;-)
I don’t think he will pull a David Hahn
Easily one of the most interesting channels on youtube.
That was fun to watch. And here I WS thinking “temperd glass” will be hard to make. Just any glass is hard.
Haha, I love this channel. Popped up by TH-cam after I wanted to mint coins (lol, it's out of my head now) and just by reading the channels name, I bookmarked it instantly. Love this stuff. Ok I won't try to make my own glass also... Hahahaha
Enjoyed your video and I gave it a Thumbs Up
Let's give props to the smith who forged a metal pipe for glass blowing. It's quite difficult.
Finally new vid
Well done
Instead of a linear retracing of historical technology development, I think it would be WAYYYY more interesting to see a channel/video series dedicated to thinking outside the box and developing to electromagnetic power technologies from "zero" via alternative methods, even if that means they do not neccessarily look like how we know them as today.
