It might be interesting to try rubbing your hand on some brass for awhile and then swabbing your hand, to see if you can detect any getting transferred
Good info. It is interesting that the tests did not confirm general bias about whose pens would and wouldn’t contain lead. 👍🏼
Yeah it was interesting the tests gave results that were the other way around.
Yes indeed. I heard on several forums that leaded brass was banned in germany and US. And yet here we are. 🤷🏻♂️ thanks for taking up my request DB!
I have quite a few brass pocket pens from Chinese companies like Delike..
When I commented to one of the Instagram posts by Ben Walsh of Gravitas that “I mostly use these Affordable Chinese brass pens when I travel”, he had made a sarcastic comment about lead contents in them which made me worried to be honest..
But your test results on actual Lead content in one such pen is a pleasant surprise for me for sure !!
I think it isn't lead you should be concerned about in brass things, it's copper in the brass alloy (Cu 66%, Zn 34%).
Looks like it time to give the brass Gravitas pens a test!
Man, you do the most amazing things. How have you not won a Nobel yet?
I don't think swabbing pens would get a Nobel prize, or even a noble prize 😉
Fun fact that you'll probably know:
The element symbol for lead is Pb from plumbum (Latin). They used to make pipes for drinking water out of lead. That's where the name plummer came from.
Nice vid. Pretty much aligned with my knowledge and understanding of handling lead and getting ill with saturnism. I don't know about North America, but here in Europe fishing weights are pretty much pure lead, people handle them without gloves for decades, I don't think anyone even thinks about it. Just enjoy your pens.
Our fishing weights are also usually lead in USA, there are some tin and steel ones on the market too
Yes I grew up in America with lead fishing weights, we would even bite on the edge of the split shot to open them up, and bite on them again to close them down over the line. Target shooting involves lead in the ammo too, and when you clean the bores of the guns you pull out patches covered in lead fouling.
This is a very informative video, but you can actually get lead poisoning from prolonged contact with surfaces that contain lead. Your skin is porous and can absorb small traces of lead through different processes. However this will be a non-concern if your pens are properly coated, and even then a 3% lead containing alloy will need a long time to become even slightly toxic. Just, if you use your pen multiple hours a day (for some reason) don't get a naked brass pen
Its really tough to tell how much exposure is required for skin contact. These are only hovering around 3% lead (for raw pens) and then you have to take into account the surface area of the contact to your skin. The lead absorption through that amount of contact is as minimal as you can get. Absorption through skin is no problem for Organic Lead (tetraethyl lead and tetramethyl lead are the most common), but for inorganic lead the risk is very low and you need significant skin contact with very high lead concentration.
Deeply appreciate this video, I Know some majohn a1 owners like myself have had the paint entirely strip off and reveal the brass underneath and there was some chatter on the internet about it potentially having lead. This is a sfar as I know, the only definitive answer to that question :)
Nice work. As always, taking the fountain pen review in completely new, fascinating directions. Definitely the most innovative fountain pen review channel out there. Keep it up. Your efforts and content are appreciated.
It's all about exposure rate. If you ingest lead all day it will get ya, like those in Flint thay couldn't help it because it was in the water, but external exposure can be mitigated by just washing hands. These pens are safe and I'm glad you did this video to help explain that!
Yup, the risk on lead exposure is pretty much zero. Just make sure folks dont let their kids use them as soothers
I find it interesting that peopl e are so concerned with lead in something they don't eat, but then willingly poison themself with alcohol and cigaretts
Mhmmm paint chips
Very interesting thanks for sharing, I would have added that when sanding anything metallic (or anything else for that matter) wearing at least a mask is really important regardless whether there is lead or not.
Yup face mask is good. Mentioned that if you feel like sanding a brass pen, use some type of raspatory protection and gloss are a good idea.
Great video! There is definitely a lot of food for thought in this week's exciting episode. I'm not going to worry about any of my current pens but it's always good to know what's going on with the objects you handle. Well done and thanks!
Nice topic to explore. Never thought about it before but good to gain some insight.
Thanks for sharing! It seems a lot of people are worried about lead in materials, but I haven't heard about anyone getting lead poisoning in years. I am curious about a few other pens, but I won't bug you too much about it.
Amazing video DB. Everyone assumes that Chinese fountain pens, the Majohn A1 for example, is just a soup of lead source.
Very nice and informative video. Thanks DB.
Very interesting testing, DB!
Glad no pen was harmed in the making of this video, neither physically nor reputationally!
Nice work!
i found you recently, and a few days into watching you, reminded me of AvE. the mention of shop, focus you..., hand comparison, voice, work mat and western canada references like skookum
I grew up in the same region he lives in and we said Skookum to everything LOL. AvE actually has a shop, I have a POS 1 car garage in my townhouse where I have one fold up bench to work on LOL. But yes, both of our cameras have a mission to focus on everything EXCEPT what I'm trying to show you. I just happen to edit out my "Fu**ing focus you fu**ing POS!!!!!" I would have no problem creating an R rated reel of stuff I edit out 😆
Valid and (frankly) wonderful direction to take QA testing for Pens (among other things). While we don't hear so much about lead poisoning anymore (other than "It's bad" of course) there comes a certain false sense of safety about hazardous materials in modern components and products. Whether you're a parent with children that might even be tempted to gnaw on pens, or you're a tinker who likes to shape, decorate, grind, polish or otherwise fiddle with metal parts and systems, it pays dividends to know what may or may not have lead involved. Even that it's generally just sloppy and foolish to go grinding on metal without a mask, there are those who insist (and will insist) that just doing the work outdoors is good enough.
Lead can still be found everywhere if you look hard enough. There are ancient pipes underground all over the U.S. infrastructure, and lead gets involved to "tolerable levels" in things from solder to welding rods and even tubing and plumbing fittings... It's DEFINITELY worth putting out there, even with the follow-up that with reasonable precautions, it's not so serious a hazard. ;o)
Thanks for your re-assurance regarding the safety of the Majohn A1 as I bought one after viewing your videos comparing them with the Pilot original. Pity you don't get a choice of nib size.
Not unless you fit Pilot internals.
This brings to mind when I learned about indentured servants in early USA, when I was in 7th grade. According to Mrs. Smitherman such were registered by taking dental prints by making them bite on a thin sheet of lead. Sounded interesting so I got some lead and pounded it thinnish and bit it. Couldn't get a readable print, but did get aan interesting headache, quite similar to the one I got 3 years later by wearing some glasses I found for a copule hours.
Interesting tests Doodlebud, thanks for sharing.
Great information to know, stuff that hadn't crossed my mind before. Thanks! Curious about ink, whether there are any components we should be concerned about?
My doctors once thought I had lead poisoning, like severe. Nope did the bone scrape test, which really sucks, and just have osteopetrosis. Really really dense bones. High enough exposure has it bond to your bones and shows up on x-ray.
Interesting video 😀 Thanks 👍
I am glad you mentioned a number of times that one has to ingest lead for it to be poisonous to your body. Even if fountain pen ink has lead you would have to ingest the ink, not simply touch it. Licking your inky fingers to wipe them clean may not be advisable.
Good demonstration.
Might make pen chewers think twice!
@@archivist17 I wonder about the wooden pencils that growing up many have chewed on. I wonder if there was any lead in the coating or is the lead had any lead, if you know what I mean.
The vintage Esterbrook felt tip markers ultimately were discontinued when the government stopped the selling of the ink for them. Wicked high level of lead. Only "fountain pen adjacent" ink I know of that had lead.
Frankly, I'd have worried more about the "51" and Superchrome inks Parker had for the 51. Until it came out that they even ate the early sterling silver breather tubes out of the pens, and melted the latex pump for the Vacumatic and everything for other brands of pens except for the gold nibs. I think they self pulled them off the market. After the outcry.
Sorting type while watching this surprised at how few people here know about setting type.
Hi DB!: INTERESTING video! I wonder, if you swab your gold nibs with the testers will they turn red? I know pure gold is not toxic, but 14 and 18 karat gold is an alloy. Since gold is near to lead chemically it would be interesting to see if anything happens! You really shouldn't suck on your nibs either!
More important than with fountain pens, fountain pen ink is more of a concern. Many pigments have lead content, as far as I know, none of the ink companies are vetting with an authority to test for lead. Further, the fountain pen community prides itself with inky fingers, which can lead to contamination during mealtime. Further analysis is needed, no?
With all due respect to Chinese products, and they certainly aren’t the only ones that fall into this category, this is one of the reasons I really struggle with the idea of saving a few bucks by buying ink from them.
@@CIRCLEDARK Your comment seems in pretty poor taste considering the cheapest, knockoff quality pens from China in this video were the only ones to not contain any detectable lead lmao. On top of that, I don't think I've even heard of any Chinese fountain pen inks outside of those pre-bundled with certain pens. Most inks are made in Europe, the US and Japan, none of which require ingredient lists for proprietary ink mixes that aren't used for food labels or tattoos. Chinese products made as legitimate exports have to meet the same safety standards our own local products do to be sold, so if you're buying from a proper vendor you have just as much chance to be poisoned by a US, Japanese or European product.
This was interesting. I had never considered it before.
Would the oxidation layer on a patinaed brass or bronze pen be enough of a barrier?
Well on the kaweco clip it had a good length of time having a patina and it showed up as containing lead, so not sure on that one.
Hi dood! would you mind testing the Delike Hunyuan brass as well? I have the same pen and I would like to know if there's lead in it. Thanks a lot.
Dont have that pen but this test is easy enough for anyone to do at home and test all the pens (and anything else) they want.
I have never given that a thought...
Please review FiGo 24 Carat liquid fountain pen, it's a cheap copy of LAMY safari, and also compare it with LAMY safari. Thank you.
is Sodium Rhodizonate dangerous?
Hey doodlebud, would that kaweco sport clone happen to be a delike pen? I've been wondering for a while if their brass pens actually contained lead, but I've never found tests on them until now.
I think it is the Delike but its tough to say. This same pen pops up under so many names. Its the exact same place making it but comes under different brands. Its sort of like Amazon where you see the exact same earbuds but just have different brands names put on them.
@@Doodlebud That's good to know. Been wanting to pick up a delike element and a moonman m1 and knowing they are likely lead free makes it an easier decision lol. Thanks!
Wash your hands once in awhile, folks. Especially before you go to lunch. If you solder using 60/40, don't also suck your thumb. Well really, don't suck your thumb anyway, but you get the point.
Does having a cut on your hands make any difference in absorption? Just curious.
Can't say for sure but I would say most likely. But again would only apply to raw brass pens that use brass (or other materials) that contain lead. And again its a very small content ~3%. Also have to consider the surface area of the open cut and what the absorption would be. I would just really say make sure your little kidos don't a pen as a soother.
... are you worried about the mercury in your old teeth dental fillings?
Nope... don;t have any 😜
Another good one doodlebud!
Lead is in fact absorbed through the skin. One may say it's not enough to cause lead poisoning, but current science is that actually there is no level of lead exposure which does not have harmful effects.
I am curious about Homo Sapiens Bronze Age 🤨
These swabs corrosive to the brass?
What's 60 seconds?
@@Doodlebud my bad
corrosive?
👍No not corrosive. You can wipe the pen off afterwards as well to remove any residue. It didn't impact the paint on the pens either (at least the ones I tested).
@@Doodlebud good. thanks for this btw. While you and I and other pen lovers won't stick out tongue into pen barrels. kids may. or pets.
@@paulchiu yup, figured it was worth doing the test so folks know.
Plenty of people chew on their cheap Bic ball point pens. It may transfer to adulthood when they can use nicer pens.
Ooh interesting
👍
imagine he dips it in the water and it turns pink lol
Truly fascinating. I'm really curious to see what the subreddit would have to say about all of this. I honestly expected the cheaper pens to have lead, and not the more expensive big-name brands.
For the record, I will happily live and die by plain old 60/40 lead solder. I could never make a solid joint with the lead free crap. And I say anyone who does hobby circuitry can afford the hit to their smarts that it causes 🤓
You need to set the temperature on your soldering iron a bit higher!
There goes another battle between the logical and the emotional brain. It's safe but there is still that visceral feeling of wanting to stay away from it. Logic will win, I think. I'm sure. Yes, it will. I hope. Good video :)
Logic rarely seems to be the winner in discussions 😒
Don’t eat pens
You did not test the knockoffs the same way you did the German and Japanese pens. Really? Just the outside of the crap and the on the higher end ones you go digging inside to find exposed metal that a user would in all likelihood never come in contact with. Now you have shown yourself to be an alarmist for no useful reason. Either remove this video or redo it with the same type of vigor on all the pens shown.
They sanded the coating off to expose the brass fully, and used the section and the clicker, both of which are the parts you touch the most lmao. Low effort troll.
The same vigor? I had to sand parts of the Chinese pens to reveal the brass. FYI the brass on the inside diameter is the same brass on the outside diameter. And I also dug inside the cap of the WingSung 630 to show lead on the brass screw. The bronze clip on the kaweco was in plain sight and tested that too. Apparently you didn't pay attention at. And no, I won't be removing this video
