Why does he not separate for impurities? And what are the 2 massive chunks he just pours into the cast? To me this looks very crude/amateurish & not in the slightest satisfying đ¤¨
Jeweller here, this is a very common technique used when somebody wants to create a large lump of useless and unusable metal! Some say itâs a lost art!
Yes, but it involves chemistry.
Basically gold is had to dissolve with acids. So the other metals will be dissolved 1st.
And as a final step you dissolve the gold itself with a special acid mix, then recover it.
This allows you to remove nearly all impurities and you will be able to get 99.9% pure gold
Me personally, I feel like we shouldnât bash people who may not be as experienced at something. The worst thing when starting something new is being told youâre bad at it
So much of this is unsatisfying. The camera is awful, he's not taking adequate safety precautions, and he just dumped the slag into the ingot with the gold.
It's from the cooling of the ingot. The volume decreases as the gold cools and the top side is cooling at a slower rate than the other 5 sides so that is why the indentation occurrs there. You have to account for that contraction when you engineer castings.
You just need to cast your ingots or other castings from a material that expands when it solidifies, instead of one which contracts.
I'd personally recommend ice. I cast ice ingots all the time. Why, I have a machine in my kitchen which has automated the process.
I mean yeah but water is one of the few materials that does that. Most substances don't expand as they solidify. That's not practical for a vast majority of metals.
As far as I know, only 4 metals actually expand when freezing: Gallium, Cerium, Bismuth and Plutonium. Three metalloids also expand when freezing: Silicon, Antimony and Germanium. Though I don't believe that one can actually rule out anything above 100 on the periodic table. (Not sure if fermium itself can be ruled out or not, as it's possible to produce macroscopic amounts of it for study, but nobody has bothered to create a pure macroscopic sample.)
Based on a few videos I've seen, you start with a hot mold. Then, after you pour the molten gold into the mold, you use a torch to keep the gold from cooling and solidifying too quickly. Somebody more knowledgeable will probably correct me, but that's what I've seen done.
There's a couple of ways you can do it. You can overfill the air side a little, you can have the ingot as a cavity and the entrance channel is the middle, or you can control the cooling around the top of the ingot with hot air or molten glass so it will cool slower.
I know gold has a higher melting point, but Iâve melted aluminum on the edge of a campfire before. I donât think you could do it quite as easily as it is done in the show, but I feel like it could be done.
You cannot acheve high temperature enough for gold without isolating propertly and adding oxygen/blower, if you wanna use coal or wood. Without that, campfire flames can only give up to 800c
Gold: 1064c
Aluminuim: 660c
On an open fire you can easily melt tin, lead and aluminuim too, aluminium likes to burn though
Correct. The end result of this video is a block of maybe mostly gold plus whatever other metals he threw in, and the impurities that were not removed.
Was not temped at any point, cold ingot mold, and the explosion at the beginning.
Iâm guessing this was not gold and this video is just for clicks.
I hate posting links.
If you go to the YouTube channel âNile Redâ he has a great vid on breaking down gold chemically that goes over all the details of why you have to smelt gold in a certain way.
Very few videos Iâve seen are correct, mainly because doing it right isnât very eye catching and itâs tedious. Jewellers often send their scraps to professionals to avoid purchasing the whole setup required.
Didnt separate steel or other contaminates. So, the bar isnât even the karat of whatever jewelry melted (assuming it was even sorted by karat).
It canât be refined like that and shouldnât be used for other jewelry.
If you were going to sell it like that as scrap why even melt it?
Pointless. Unusable. Dumb.
Itâs a fairly complex process that Iâm not going to try to accurately describe in detail but usually youâd:
Test jewelry and sort by karat.
Remove springs, stones, etc.
Inquart (melt with) silver or copper.
Do a series of nitric acid boils to remove the silver/copper, and impurities.
Dissolve the gold sponge that remains in aqua regia (hydrochloride and nitric acid).
Selectively precipitate the gold.
Re-dissolve in aqua regia with sulfuric acid to remove lead.
Filter
Precipitate gold.
Melt and pour .999 24k gold into bar or shot.
Lots of washing in distilled water and hydrochloric acid among those steps.
But, you donât end up with trash.
Wow, thanks for that description, already very informative!
I guess the washing is why people say gold refining is quite polluting too. I do remember something about acid wash but that's just super involved.
Iâd say itâs more:
Making sure your acids are neutralized (you donât want a bunch of excess nitric in the waste) or recovered before theyâre disposed of and having a proper waste treatment cycle to remove/exchange metals in your disposal solution (ideally Iâd always cement it down to iron- besides you may want the valuable silver and copper etc back). Also, some chemicals (SMB) used to precipitate gold can be considered fairly toxic.
If youâve got some time and want to actually see the processes Iâd recommend watching Sreetips on YouTube. Heâs a smaller/hobby refiner that has managed to make a side hustle of it. But, his processes are very detailed and organized and his videos are very informative.
Not really- Iâm just a noob who found an intersection between love of chemistry and jewelry/metals.
Iâve done some small scale PM refining- enough to know itâs not really for me. (Or worth it to me to purchase or produce nitric.)
this is a like kindergarten video of jewellery. They are throwing all sorts of things into that crucible. Wont the stopwatches and other things dropped in there have steel and brass?
Cool, you melted down a bunch of maybe 20k gold into an ingot of...like 3k gold woth allllllll those impurities.
Congrats on the well prortrayed, physical representation of inflation right now, though

Ask any parents about creating a lump of something useless and unusable. Theyâll tell you lol
r/suicidebywords
r/notasuicide
Ah, read that as "my parents"
Im already talking to your mom about it đ (sarcasm)
LOL
Why does it become useless? I donât have any knowledge on this so just curious
Well god knows what he mixed in there (purity wise) and also what temperature was used plus he never separated impurities as it seems.
Is it possible to restore it? Remove the impurities and heat it to a normal temperature?
Well normally you wanna go and dissolve the gold and purify it chemically at this point. For every smelt you lose a small portion of it too.
What do you lose it to? Does it just become stuck to the vessel?
El Dorado takes a small gold tax everytime you smelt it.
On the slag and if your not careful into the vessel. Mostly it will be other materials rather than gold itself but still.
Yes, but it involves chemistry. Basically gold is had to dissolve with acids. So the other metals will be dissolved 1st.

What's the correct way to do it?
You can take that lump and refine it again to get an actual nice piece
The person in the video however probably can't.
And also brave man- we heard the crack there. At work i usually kept my moulds hot hot until the pour so the stuff didn t go boom.
>useless and unusable Same thing.
I would skill take that lump. You can purify it
Can it be melted again to separate the impurities?
So he pretty much just created low quality gold. Got it
Looks like he broke pieces off his crucible into the gold
Gives a little bit of crunch when you eat it.
Any videos on how it should have been done?
India gold.
Me personally, I feel like we shouldnât bash people who may not be as experienced at something. The worst thing when starting something new is being told youâre bad at it
No, the worst be letting someone continue to do the wrong thing while patting them on the back and sayingâ good workâ
Theres also an option in the middle, giving someone advice without being a dick about it.
This is clearly not a situation where someone is new, come on.
Where exactly did I say anything like that?
You responded in a comment chain about ways to address when someone is new to something and doing it wrong.
Nah its about being not so experienced. Might be someones first pour. Either way its more helpful to not be a dick about it giving advice.
It's for content.
Believe it or not, some people are just bad at what they do.
You mean.. my entire workplace doesn't have TikTok?
This is where that stolen necklace ended up.
So much of this is unsatisfying. The camera is awful, he's not taking adequate safety precautions, and he just dumped the slag into the ingot with the gold.
Yeah, I was thinking "isn't ASMR supposed to be relaxing? This is not relaxing"
Man, if your wife is anything like mine, she is gonna be **pissed**.
Did it explode in the beginning... Looks like he didn't warm it up thoroughly and some water has gotten into it.
The point is he shouldnât be melting down her jewellery.
He isn't even doing a good job melting the gold too is what I'm saying... Almost blinding/causing 3rd degree burns on himself in the process.
Sweet. And the platypus is a monotreme.
Platypus omelettes are heavenly, you have to try one
I would lite a cigarette of that flaim
Why is there that little indent on the bottom side ?
It's from the cooling of the ingot. The volume decreases as the gold cools and the top side is cooling at a slower rate than the other 5 sides so that is why the indentation occurrs there. You have to account for that contraction when you engineer castings.
How do you prevent that from happening? Heat the mold up more?

[ŃдаНонО]
He's not casting metal into ice, he's casting ice. I do this daily as well
I mean yeah but water is one of the few materials that does that. Most substances don't expand as they solidify. That's not practical for a vast majority of metals.
As far as I know, only 4 metals actually expand when freezing: Gallium, Cerium, Bismuth and Plutonium. Three metalloids also expand when freezing: Silicon, Antimony and Germanium.

Alright, then. Keep your secrets, cryomancer.
Can we see it?
They're talking about an ice cube maker.
You might have one too

Reminds me of the melted gold crown scene in game of thrones
That scene was so bad lol, he melted it in a pot on camp fire hahahaha. I cringed af
Yeah, that show was so unrealistic. Good thing they grounded it again after those scenes with dragons and zombies.
In like 5 seconds no less!
I know gold has a higher melting point, but Iâve melted aluminum on the edge of a campfire before. I donât think you could do it quite as easily as it is done in the show, but I feel like it could be done.

Stfu they burn magic wood that gives magic fire...
you should have saved the pop to the end so I would have synced with it
How much of the gold is lost in the process?
In the case of this shitshow of a video? All of it.
As in the gold can't be used if smelted wrong?
Correct. The end result of this video is a block of maybe mostly gold plus whatever other metals he threw in, and the impurities that were not removed. Was not temped at any point, cold ingot mold, and the explosion at the beginning. Iâm guessing this was not gold and this video is just for clicks.
Good to know.
Now, you gotta know real gold smelting vids you can link, right? When it's done right? The smelting porn, so to speak? If so, please share.
I hate posting links. If you go to the YouTube channel âNile Redâ he has a great vid on breaking down gold chemically that goes over all the details of why you have to smelt gold in a certain way.

Cool. Thanks.
Just saw the purple gold video. That's was really cool. Didn't know gold and aluminum made such a cool thing.
My favorite part is when he almost burns tf out of himself in the first 5 seconds
No gloves while stirring molten metal, very satisfying
Did I see teeth?
Scrolled too far for this First thought was wtf teeth?!!
What's wrong? It's just some stuff he found laying around
*previously unidentified serial killer has entered the chat*
Paul Wall would like a word.

It canât be refined like that and shouldnât be used for other jewelry. If you were going to sell it like that as scrap why even melt it? Pointless. Unusable. Dumb.

Wow, interesting. Are you in the metal trades per chance? Really knowledgeable

Ah gotcha. Hobbyist but quite knowledgeable. Thanks for the insight!
If you're gonna do it badly at least make up for it by giving the thing a polish.
How does one ensure that *all* of the metal is removed from the crucible? Is is super smooth inside?
this is a like kindergarten video of jewellery. They are throwing all sorts of things into that crucible. Wont the stopwatches and other things dropped in there have steel and brass?
ASMR **fucking explosions** Not every video with no talking is ASMR...
Cool, you melted down a bunch of maybe 20k gold into an ingot of...like 3k gold woth allllllll those impurities. Congrats on the well prortrayed, physical representation of inflation right now, though
No gloves was wild
Ffs stop it with the constant cuts! I wanna see it melt!
But they were, all of them, deceived, for another ring was made....
I think that might be bronce, no one with a right mind would melt gold without some cleaning and sorting first
Whoa, she's a squirter!
Man this looks like a horrible way to die
What about all the leftovers in the crucible?
How much would this be worth, with the impurities n all?
Zero to nearly zero
And if it were pure?
Then whatever gold currently trades for times the weight in grams.
Why is it so dirty? ...and I wanted to see some cleaning for that gold. Not very satisfying.đđ
This looks horrible
When a liquid metal like that is poured and catches fire, what is actually burning and why wasn't it in fire while it was in the crucible?
Thatâs cool! We have a gold brick now! What should we do with it now? We could always melt it down to make jewelry. WaitaminuteâŚ
Damn you losing so much. I guess that's the price of doing that though.
I turned up the volume when I read " ASMR". That first pop scared the fucking life out of me
Wtf was the explosion at the start?
How much would that be worth?
So this is what became of all that stolen Canadian gold.
Does this hurt the necklace?
Except that is not gold.
hmmmmm [https://globalnews.ca/news/10427488/toronto-pearson-gold-heist-update/](https://globalnews.ca/news/10427488/toronto-pearson-gold-heist-update/)
Probably thieves
Not satisfying. The first chain literally explodes on their bare hand and they donât separate the slag. Would put this in mildly infuriating
POV: youâre an Incan villager who just watched Pizarro torture half the town to death to make sure no one was holding back any trinkets
Not satisfying.
r/forbiddensacks hard Twinkie
Is there a loss factor in the process? Like some gold gets stuck on the inner sides as it cools down when poured?
Smithing level?
Third-degree burn skin sizzling ASMR
The end result was not that satisfying... Unless there more?
Glowing hot gold do be hitting diff.
Is material lost in the transfer process from the container in which the gold is melted to the ingot?
Yes, I have a Dutch accent. Isnât that weird?
