when will u make video about turning bismuth slag to normal bismuth?
just asking ;)
Not sure unfortunately atm. I will need to get my lab set up but that can't happen until some major renovation happen.
@@TrollFaceTheMan ok i ll wait :)
@@TrollFaceTheMan Also waiting for this! I've been experimenting, would love to compare notes, really looking forward to your video on recovering slag!
I've been making bismuth crystals as a past time for a while now and I have a few tips.
First is that your crystals are coming out miscoloured because they are cooling to quickly once removed. They are coming out that mudy purple-blue. Once exposed to air the crystals have to be put into an environment where they cool slowly and if so they come out bright and with the full spectrum of colors. Do this by heating a oven to 450°-475° and immediately put the crystals in there to cool for an hour or so. Then you will get the intended bright colors.
Second, your crystals just need to be cooling slower overall. If they are cooling to fast you get the more cubic and pillar-like crystals that you are pulling out. If they cool slow you get more defined fan and pyramid-like crystal you see online. I tried half a dozen different cooling methods but in the end a oven between 400-500° degrees is easiest and works the best by far. Hope you can use some of this advise to crank out some high quality crystals!
Thanks for the input, good to know!
Hello, What exactly do you mean by put the crystals in an oven? Like you mean once they are out heat them again in a mircowave?
@@adhip0574 In a conventional oven you would use for baking, not a microwave haha.
@@d.barrett578 Haha apologies for the confusion, however my mind still has a few doubts, when taking the bismuth crystal and cuting it the color already forms, so does it mean that we need to place the entire pot into the oven or the short time of oxygen is still fine?
Also once its in the oven do we need to keep the oven running or just let in cool in the oven itself?
Finally how do the colors change? I know the color depends on the thickness of the oxide which depends on the cooling but is it the temperate of the environment or the temperature of the bismuth when exposed to oxygen?
Sorry for asking too many questions just wanna understand the chemistry behind it.
@@adhip0574 I can't say I know the exact mechanisms behind it. But for some reason the color on the outer oxide layer of crystals is completely dependent on how quickly they cool after being exposed from the liquid metal. Left at room temperature when exposed 9/10 times they will become a muddy dark purple with very little sheen to it. Sometimes they will end up 2 tone (usually blue/yellow. The only times I get the full spectrum of colors on crystals is if they are put into a 350ish degree oven until the oxide layer has completely set.
In my experience as long as the oven is 100-150 degrees cooler than the melting point of bismuth and they are put in the second after your pour out the remaining liquid you will get great color.
Again this is all after you do the main cooling process to form the crystals by letting the liquid metal cool slowly. Then when you believe you have had crystals that have formed you pour out the remaining liquid and do the aforementioned crystal cooling in the oven.
Did he just pronounce bismuth like bis mewth
Yeah, like the famous Pokémon XD
I’m 43 yrs old no just discovering bismuth like this! I’ve known it was in Pepto but never knew what it looked like in crystal form. This may be my new favorite metal just because of how rad it looks when it comes out like these!
The most informative bismuth video I've seen. I appreciate your thoroughness and willingness to explain stuff that people often say about bismuth and the crystal growing process but isn't often explained.
Glad you found it useful, and thank you for the comment :]
Thank you! This was the video I was waiting for. The trick with the sand to cool the bismuth slowly is great!
Glad it helped.
Thank you for the kikass vid! I tried to find the follow up video for repurposing the "slag" to no avail. I can't wait to try this myself! Stay safe & humble. Ciao 4 Now
I haven't made it yet sadly. I have been very busy, but plan to. Thank you I am glad you liked it and left a comment!
Super detailed and *follow-alongable*!! Thanks, brother!
Glad the video was useful :]
Excellent video, very informative and great humor. Thank you for sharing.
Thanks, glad you like it :)
Thanks a lot! I bought 3 pounds on ebay and was worried when everyone was saying that I need 5+ lbs. Learned a lot from this, so thanks!
Welcome, good luck :]
6:51 If you turn on the captions here, it says "the hot pissed mute" 😂
Hawt piz moot!!!!
Oh my...
nice tip with the sand ! just ordered 3kg of busmith ! can't wait !
Good luck! :)
Thank you I am a high school science teacher this video was very helpful .
Glad to hear :]
They are beautiful. Thank you for sharing!
Glad you like them, and thanks for your comment :]
Those are so pretty...I Love all the purples and blues
Thanks, glad you liked the video :)
Superb, love it!
Thank you :]
love all the information!!!
Glad you do :)
Interesting awesome information, thank you 😊
Welcome!
Really cool man!
Thank you
This is awesome! Side note: totally pronouncing it Bismewth from here on out. Bismuth is such an ugly sounding trash word.
But BisMewth... now THAT is a powerful sounding Pokemon name, and I am here for it.
XD
Thanks.
Great video!
I wonder, since bismuth has such low thermal conductivity, could one use a temperature controlled sand-bath to keep the bottom and sides close to the melting point so that heat loss happens though top surface mostly? The idea being to slow down crystal formation from sides and bottom allowing more room for the crystals to grow from the top?
Interesting, I am not sure. Keep in mind even with a low thermal conductivity the liquid may naturally convect a bit moving heat better. And also the deeper the pool is the quicker it can transfer even with lower conductivity because of the crossectional area.
Fun Fact: Bismuth is actually pronounced like Bismyth!! Even years later I still manage to impress everyone with gross pronunciation oversites!!
Oh well... "We'll get them next time..."
TrollFaceTheMan Honestly in science there’s no real wrong pronunciation IMO. But thanks for addressing this mewth.
Sasha Soule yeah nah. There actually is a correct pronunciation for everything.
Oversights
I wonder what they say about handling precious metals, like Gold & Silver, are they hazardous, if not thwn i wonder if they might be Beneficial in small quantities as A medicine for certain problems, Very informative 💪
Have you made a video of bismuth slag/dross recovery yet, very interested in this, seems such a waste to just throw it out. And thank you for your very informative video. Keep the awesome work your are doing.
I'm also waiting for this video on what he does with the "slag" turning it into a usable metal
I have unfortunately not yet. This last two years have been a lot including going deaf and finding out it was a brain tumor, getting it removed and in recovery. I apologize. I hope to get to it soon.
@@TrollFaceTheMan Thank you
@@tedjones1545 welcome.
@TrollFaceTheMan some good information in this video. I have grown bismuth crystals, after experimenting with growing them I figured out that they needed a slow cooling time but didn't think of using sand that is a good tip.
My largest crystals are about 2x2x1 inches If you are interested I have a few videos on my channel.
I don't want to come off as one of the guys just trying to correct you but I make this comment so hopefully both of is can learn. at @6:00 From what i understand is bismuth is denser in the liquid phase than the solid. One of only a few things that expands with solidification that also includes: germanium, silicon, gallium and water. Bismuth expands 3.32% on solidification.
With that in mind if it is not expanding what pushes that little glob of liquid to the top? Do you think it could be the surface tension and the weight of the solid metal floating on the surface? That must also be why the crystals float since they are less dense.
I forgot to mention I am excited for the bismuth slag video, I always save mine and have wonder how to purify(reduce?) it but just have not taken the time to look into it.
Interesting I did not know that and that is a good thing to know. However even though it is more dense in liquid form that doesn't mean nessicerally that the non melted metal doesn't expand slightly while heated.
Perhaps enough that when there is a small molten pocket inside that the solid metal gaining volume before melting might compress it and force it to the surface. However this is only a theory.
That aside I did also think of your point of the solid metal pushing down on the liquid and forcing it up but the issue with that is one the container shape being slightly inward should not let it fall downard.
And two because the molten bismuth is more dense the solid bismuth should never sink low enough in it to go below the 'Water Line'.
Coupled with surface tension then maybe but I am unsure the mechanics in that case.
I am sure that you are right and one of the reasons the crystals float so well is the lower density but in personal testing with things like salt an such it is still common for crystals to float on less dense substances while forming until they have overcome surface tension and sink.
I actually always welcome corrections or input when down in a constructive and/or genuinely respectful way. Thank you.
@@TrollFaceTheMan Thanks for the reply, yeah it's quite hard to tell what is going on. I see your point at first I thought more was melted when the blob pushed out but now i see it's a whole separate video shot then the frame before. Interesting to think about why that happened, you might be right that it's the solid metal expanding with heating squeezing out the liquid. I wonder if it's bismuth's crazy crystal structure that makes it expand on solidification or something else.
I would like to know how to recover the slag into re-usable metal. Still planning on making that video?
In the future yes :)
With a couple exceptions, bismuth slag is pretty much just bismuth oxide. So it should be reasonably simple to break it back into oxygen and bismuth metal
Hmm. I wonder, with a few seed crystals in the apparatus, what kind of crystals you could grow from bismuth vapor. Get it boiling, collect the vapor in some kind of tube that has seed crystals inside of it. Place it far enough away that the vapor will condense in the tube. Wait for a while, remove and cut in half. I really wonder what the results would be.
Great content! I would have two questions, I would ask younfor your experience or oppinion. (1) Do you have experiments with providing a cooling finger as nucleation point? (E.g. a mounted screw driver). (2) Does this also work with Pb-Bi alloy. The eutectic is at about 125 °C and I think trying this.
I have not done that yet, nor do I know if it will work with that alloy. I apologize I can't be more help.
Very nice...
Thanks.
What material do you recommend the container used to melt the bismuth be made of? I've heard stainless steel as the common answer, and maybe you said it in the video and I just didn't hear it, lol.
Steel is good. But I believe iron could be fine too.
Can it be heated ‘too’ long? No times were mentioned and I worry my neurosis will effect the results.
Heating too long would mainly just be an issue of forming slag on the top and slowly wasting your good metal.
Yo bro I need some advice. My bismuth crystals are fading in colour... what’s happening and how do I restore its colour?
I am not sure, I haven't had that issue. The color should come from micro oxide layers on the surface. Maybe something is reacting and removing them?
If so maybe sealing the crystal with clear coat may stop it.
"BIZMEWTH"
Just like the Pokemon ;]
Nice work, the music reminds me of How It's Made!
Thanks :)
the contact hazard ratings for Cu/Ni are purely due to potential allergic reactions in some individuals
I actually have a bismuth mine on my property .. there are two claims on my property one is bismuth tellurium gold the other is gold and sulfur. The Bismuth maybe non-toxic relatively but the tellurium I've been told is toxic and they're both slightly radioactive the Bismuth not so much though
It's possible that the ores could be toxic. Or that there is metal salts that are toxic there.
So for example copper is normally relatively safe to handle, even eat in small quantities.
While copper sulfate is extremely toxic becuase the copper is much more bioavaliable.
i find this hilarious because i tried bismuth making last week and i poured a crapload of water straight into the molten metal and it exploded all over my kitchen. hes not lying molten metal doesnt feel good on the face. shoulda watched this video beforehand
Hopefully you didn't get hurt too badly?
@@TrollFaceTheMan just a couple minor burns lol
@@Fueled_Rage that is good at least.
Hello, What would happen if you add a small piece of metal when the bismuth is growing for the crystal to cool on, would it mean the crytals can form earlier or is it a stupid idea.
Might work
@@jupiter_ios Epic! Now i need to get some bismuth and a life
@@adhip0574 Some people already tried
@@jupiter_ios How did it go for them?
@@adhip0574 When they put something like a metal rod in the molten bismuth, and take it out 10 secs later, it may be covered in a film of bismuth and some crystals may grow.
Nontoxic bullets! How considerate 😁
For things like hunting so Lead doesn't end up in waterways and such.
@@TrollFaceTheMan Yeah, I get it. It just made me chuckle to hear it is all. 👍
How much Bismuth in gram this you use in the vid. (google transl. i'm dutch )
I am not sure, I apologize it was a long time ago.
Hey, how much Bismuth did you use in this video?
I am not sure, it was a long time ago.
hi. Can you make money with it? i mean, what can i make with the Crystals?
Sure you can, but that is all up to finding people to buy it.
Trollfaceman I am hoping you can answer me , I can't find this specific info on the internet , after getting 6 pounds of 99.99% metal I ruined the metal(it never changes from silver color and on previous attempts it went through all the colors) by apparently leaving it molten for an hour and apparently having oxygen introduced through the entire metal , unfortunately I can't get 99.99% purity anymore but can get 99% , will I be able to get proper crystals with 99% ? (seller cannot tell me what the other 1% is)
You are getting crystals to form though?
@@TrollFaceTheMan yes from my original metal I am still getting square crystal formations , but the colour of the metal never shifts from silver
@@TrollFaceTheMan first attempt was with supposedly 99.99% bismuth , first melt had all the colours , after that 4 melts and all of them stayed silver , Reddit told me I have introduced oxygen to the entire metal mass, no matter what I do my metal stays silver colour, I was hoping If you know can I get some colorful crystals with 99% bismuth instead of 99.99% because I can only get 99% now
@@martin518441 I am not sure sorry, I never had that issue before. Hopefully you can figure it out. Have you been skimming off the slag that forms?
@@TrollFaceTheMan yes I've been skimming it several times during my attempts, on the last try barely any slag was gathering on my fork after skimming
Do you sell the crystals? I am thinking of starting to sell bismuth jewelry or crystals but I don’t know if that would be worth the effort or if I would even make significant profit. Any advice? Thanks. 😊
Just try
I do not sell them. So I have not advice. Sorry
How do you break the large bismuth bar?
Mine you could cover with a towel and tap with a hammer a few times on a hard surface.
@@TrollFaceTheMan No luck. You mind uploading a video?
@@ThePeterDislikeShow how big are we talking? Is your bismuth somewhat crumbly/flakey?
@@TrollFaceTheMan Only somewhat flaky and I was able to melt a 1-pound or so piece off it. I bought 50 pounds from Hallmark Metals and got 4 pieces.

Hi, can you add resin over the finished piece or will it melt it?
No should be fine.
Did you go to Hong kong recently or do you just collect foreign coins?
Well the Canadian ones I have are from living in Michigan which is close to the Canadian border. They end up in our circulation a lot.

I would love to do this in a nitrogen chamber so the oxide risk is zero
That would definitely be an interesting thing. Though the color comes from the high temperature oxidization so it might look silver till exposed to air then immediately go a dull grey.
@@TrollFaceTheMan well there is always a way to fight it, like maybe nitrogen gas blowers
@@VSDalSheron, I am not sure what you mean? I am saying the metal crystals will likely be silver up until moved out of the nitrogen atmosphere and into air where it will then likely turn dull grey instead of having the brilliant colors they normally do.
“Bizmyuooth” 😅

Almost sure he said Bismewth because he was such a fan of Pokémon ;]

Bis what??!🤣
Bis Mewth. Much like the Pokémon :]
...only an American could pronounce it: bis-MEWTH!!!
'Merica!
But seriously it was a big oversight by me.
I had to stop watching as your corrupt pronunciation of "Bismuth" was intolerable... sorry I tried.
Same.
Years later and I am still able to bother people with my mispronunciation of things. I feel as even though my channel has changed I am holding true to my roots!
bro...just say the word right...thats all I ask.
Nah bro.
That's the most embarrassing pronunciation of bismuth I've ever heard. Great video otherwise.
Sorry and thanks.
That's all wrong.
What is?
If you want BIG crystal you need a bigger pot, much better heat capacity tho.
Like a crucible, also encased in sand.
Then, you want A better heatsink to spur crystal growth.
Consider using a small winch to lower a piece of copper wire to just 1 to 2 centimeters into the melt.
Crystal will seed off the cooler wire and the wire strength gives ability to lift large crystals. I've found making a phase diagram helps.
It’s pronounced biz • myth NOT biz •Mewth SAY IT RIGHT 🤬🤬🤬🤬🤬🤬🤬🤬😡😡😡😡😡
he knows check his comment
Yep, silly mistake on my part.
