I think there were a couple dollars of gold at most there. He would have tried to recover it otherwise (like, he didn't actually use the anvil after the very beginning, he could have done it on an enamel tile to avoid any losses if there was a significant amount), so while I dunno how cheap the anvil is, it's probably more than the gold.
I even did not realize I can question Cody having a pill naker until read your comment! anyone other than Cody - i'd instantly though about clandestinely making mdma or smth)
Platinum is really interesting. The first people for sure to knowingly work it were Incas using a powder based process quite similar to this one. If you do end up processing platinum into a solid piece using this technique, it will hearken back to the first platinum ever purposefully worked by human hands! Neat piece of history.
You should polish that anvil face Cody, or at least a small working surface in the center. That way you can work metals without them taking a texture from the machining marks on the anvil. It also allows you to clean the anvil face much faster and more thoroughly. And it keeps the anvil from holding onto dusts from one material and contaminating another with it.
Bob Saget my dad has a generations old anvil. It's made from hardened steel throughout the entire body and traditional forged back in the 1940's, that thing withstands a disk grinder with a diamond cutting wheel with a scratch
Do you mean he shouldn't have gotten a power fist anvil? Those things are about as hard as a good Parmesan or romano. A thick piece of nice hard steel bolted to a splitting log would be much better and still pretty janky. Just my two cents
Nice work! Warm-hammered ("beaten" gold/silver) techniques like these were used in ancient times to make gold leaf only a few micrometers thick, for covering statues and temple relics. It was done in sections, making bigger sheets and cutting out specific shapes or smooth areas from the best part of each sheet to build up the gilding. This is particularly effective for images of "Spirit creatures" covered in geometrically similar scales or feathers. This is referenced in the Old Testament and traces farther back to ancient Sumerian, Chinese, and Hindu smiths and artworks thousands of years earlier. The only more efficient use of material mass was DC electroplating done with early acid batteries, but that technology was rare and then lost for ages. If you want to test the limits of your foil-making for maximum smooth area, try using a ball-peen hammer or (even better) a spherical polished hammer-stone, on a heated anvil surface to maintain an ideal temperature balance. If you are gentle & patient and can tolerate a hot workroom, you could get square-feet of foil per ounce of material.
Where's that list of things he wears gloves for? I'm forgetting a few. Math Nitroglycerin handling powdered gold EDIT: Ah yes, thank you! Uranium, making mouthwash, turkey eggs, gold balls, drinking hydric acid, making Clerci's Solution, and of course handling the notorious butter.
Nothing to do with keeping anything clean or pure, although that obviously also helps. When dealing with soft metals using polished tools will transfer the same shiny texture to the softer metal, hence removing the need to polish the ball or whatever else you're working on. If you ever get a chance to look inside a goldsmith, take a look at his tools, they're almost mirrors.
I agree, my ocd is crying, i dont care if he thinks the oils from his nasty anvil will burn away next time he heats it up' other people prolly gonna use it someday and i dont think they want nasty stuff like that in it. Gold is all about recycling lol.
I actually think Waterjet channel cut one of those things in half maybe (or some channel showed one that had been dropped). It isn't solid metal. It has plaster and cavities.
After folding it over again and again you should rip or cut it on the bias and look at it under a microscope. I would be interested in seeing the layers of cold welded gold
Cody'sLab it does indeed have some interesting properties. It is just a shame the"value" is artificially kept very high. Same as Mercury, now that it is demonised and been taken out, it got incredibly expensive, even though it's still the same old Mercury.
This is true - but I have seen him refine plenty of it from almost nothing. I have some silver bars - but would never melt them down and mix them with other elements because I could never refine them back to being pure* again like he does with seemingly little effort..
gold's value isn't artificially kept high. In fact, the value of gold has historically been very very consistent. For a set amount of gold you can typically get the same amount of goods now as a century ago, where the variance is in the value of the currency or the goods and not the metal's value. The majority of gold's value is this property. People buy gold because it has so very many useful properties and it keeps it's value. it's expensive because it is a limited quantity and has such a huge number of uses, not because some artifical intent to manipulate perceived value. There literally is no single industry or field of study in which gold is not of considerable use.
Well, Put water in dirt, put some grape seeds in there, give it a few years, and then squirt out the water out of the grapes and ferment it. Tadaa, wine.
Coal rolling is where you have a diesel truck spew out "unreasonable" (for lack of a better word) amounts of sooty exhaust. Rick rolling is where you have someone spew out "unreasonable" (for lack of a better word) amounts of profanities from listening to Never Gonna Give You Up by Rick Astley. Gold rolling... Just watch the vid. (And I can't continue the use of the word "unreasonable", anyway.)
Hi Cody. I have read some info about gold and it melting point. The thing is that all depends on particle size, The tinest the particles are the lower melting point they have. So you can even melt gold in a room temperature. So when you have made this pill during the process you just create a net of melted nanoparticles that hold together those bigger size together unmelted. Next by apply the heat to around 800oC those bigger size particles melted together still way below solid gold chunk melting point.
I'd think the bubbles are from moisture in the gold powder, cooking off under the flame. wouldn't think trapped air would expand that much, compared to the potential of moisture going to gas.
There might be moisture, but as any student in jewelry making will tell you, air alone can do worst than this. You can actually get similar result by just laminating an ingot with a wrong technique. Tiny cracks form at an extremity, then spread to the center and, when you heat it up, it makes bubbles, even if said ingot is still a few millimeters thick, regardless of being exposed to water or not.
A thought occurs; Could the bubbles be caused by trapped moisture in the gold powder, and not air..? I don't think air would expand that much... Did you try heating the powder to drive off any moisture before cold-welding it? As usual, Awesome vid.
That explanation of work hardening is amazing. You are a really good teacher. That's something I've never understood but that explanation just made it all make sense.
Nice I love the longer videos I could seriously watch two or more hours of Cody doing anything he could be taking a fat crap the whole time and I'd be like you go brotha almost there lol😅
I've produced similar 'bubbles'. They look like the kind of defects one gets when rolling a piece of metal in more than one directions. It's the surface shearing off from the core material because of the stress the rollers put on it. When rolling a sheet metal, make sure you always roll it in one direction.
Work hardening is an essential part of making bronze blades and tools. Having a home made foundry/forge myself I learned this when I tried to use a non work hardened bronze axe. Aluminium bronze is much more prone to work hardening than normal bronze and in fact can become close to as hard as some weaker steels.
Cody I know I am one of the many people commenting on your video however seeing how it is becoming more like summer in Utah I for one would love to see the gardening serious make a comeback as it was always great watching those sorts of videos and learning how to possibly do it in my own home.
DustedAsh3 That's not a scientist... at least not in the strict sense of the word. A scientist will say "I think this will do that, let's see if I'm right"
I think a better way to explain work hardening is that the crystal like structure compresses when it's smashed together. Since it wants to release this pressure it causes cracks to form when external force is applied. It shares similarity with a spring top. However unlike a spring top an external force is required to fix the stress. When heated the gold actually expands slightly. This relieves the internal pressure and allows the 'Crystals' to spring back to their proper shape but retains and strengthens the bond to the other gold atoms. Also if you put the foil into the roller slightly then heat it to about 900 then roll it. It should prevent the bubbles.
I don't know if this has already been said but Material Science Engineer (in training) here and this process is called sintering. When the loose 'snowflake crystals' are packed together to form a rough shape then the material is heated without liquifying it, the crystals undergo growth and densification happens, as voids in the material shrink and the individual crystals form grain boundaries between each other. I don't think that the material is work hardening because there isn't a microstructure before the pellet is formed but Still a great video!!
hey cody! if you sprinkle some flux like boric acid on the gold when you anneal it and kept it hot for a minute, that’ll draw out the air bubbles. that’s how it is when i work gold chain. when it’s a bar and we didn’t pour it right we just go back over and do that. hope it helps you brother
Can you cold weld the gold dust or other metal dusts in a vacuum chamber? If that works, couldn't you do a mold of sorts, where you just have to anneal it? Just googled it and there are no mentions of what would happen.
Eternia Kerbal In theory, other metals (gold is not very reactive) form an oxidative layer on the outside that prevents cold welding. If he puts them in a vaccuum, works them over (gold is particularly maleable, so this will be difficult) so that the oxidated layer is no longer covering the outside, then he can cold weld other metals, too.
The way I understand it, no. Basically the atoms of any metal in a complete vacuum with no oxidation or other film of non "like" atoms don't have a way of knowing that two pieces of the same metal are separate so they should combine when pressed together as if they were the same piece of metal. This would mean that each powder particulate can't recognize other particulates as being separate when crushed together and therefore a lab wouldn't be able to distinguish them either. I would think that the only way a lab could distinguish a pressed vs melted difference would be if there were impurities that were not uniform throughout the metal sheet. I would imagine something like taking two snowballs, dying one, and pressing them together. One side of the snowball would be dyed and the other would not. If you melted the two together and re froze them, the dye color would be uniform throughout. I am certainly not that caliber of scientist to know for sure but that's my best guess.
If you really go science you can probably detect the cold welding with a polarising microscope which shows you the grain size and orientation within the material
flexing a soda can tab back and forth about 3-5 times will harden the mount for it and will snap off eventually from getting too brittle because, like cody said, it work hardened
Signs Cody’s got that RUclips money now: he keeps hammering the gold he knows is brittle and in his head he’s like “I can refine an ounce of gold from my feces and fermented urine with a little bit of hydric acid plus I don’t show RUclips my Ferrari I just show them the library”.
You need a miniature pizza docker - the kitchen tool that is used to poke holes in pizza dough prior to baking that prevents bubbles from forming due to the trapped gasses. ------------ Haha!! I googled 'poky roller tool' and found a Wartenberg wheel! You can use it with your vibrator in the vacuum chamber! ...lmao - I think you'll understand why I'm laughing after you check the pricing from several different sources. It's made of stainless steel and I think it will resolve your bubble issue if you roll it back and forth a few times over sheets of gold. I love your channel! Thanks for the entertaining education.
The gold "crystal grains" are relatively small so they probably have small slip panes, making them more likely to crack at first. You got the right idea
Congratularions Cody, Now that you have encountered Cracking, Work Hardening and Heat Normalizing in metals, while hitting them with a hammer on an anvil you have become a blacksmith!
Cody the only person who's anvil gets more expensive after he buys it
Josh D Looks like it’s a Harbor Freight ASO (anvil shaped object) so the residual gold powder likely is worth more than the anvil was to begin with.
Ralph Smith yep it it a harbor freight anvil
Ralph Smith is it just a terrible anvil, hence it being called an "aso"?
i have the same one. it sucks.
I think there were a couple dollars of gold at most there. He would have tried to recover it otherwise (like, he didn't actually use the anvil after the very beginning, he could have done it on an enamel tile to avoid any losses if there was a significant amount), so while I dunno how cheap the anvil is, it's probably more than the gold.

Have you already doubled the value of your anvil by depositing gold on the (very rough) surface?
A thought occurs;
Could the bubbles be caused by trapped moisture in the gold powder, and not air..? I don't think air would expand that much...
Did you try heating the powder to drive off any moisture before cold-welding it?
As usual, Awesome vid.
allanjohnbreum, I thought the same thing, I didn't see your comment till after I posted mine. 😂
Its all good dude, if we had the same idea, it might not be total crap. :D
The gas in those blow torches has quite a lot of water vapor.
Sure, but that shouldn't get into the metal, and the temps should drive off any residual combustion products off of the metal...
That might be worth testing, the powder would be more inclined to contain contaminates in general.
This is one of the best explanations work hardening ive ever heard
Have you measured the density of the gold ball yet? I'd be interested to know just how much empty space there is in there with that rattle and all.

The explanation in the video is wrong, you haven't learned anything more insightful than "it gets hard"
When will Cody's mine be making a return?
I am a time traveler from 2020. It doesn't. The mine ends in 2020 for legal reasons.
Some of those grungy edges, bubbles and textures are pretty artsy. You could punch a hole in one end and call it a necklace.
Would a lab be able to distinguish that this was made by pressing instead of melting? Is there any difference in the structure of atoms at all?
The way I understand it, no. Basically the atoms of any metal in a complete vacuum with no oxidation or other film of non "like" atoms don't have a way of knowing that two pieces of the same metal are separate so they should combine when pressed together as if they were the same piece of metal. This would mean that each powder particulate can't recognize other particulates as being separate when crushed together and therefore a lab wouldn't be able to distinguish them either. I would think that the only way a lab could distinguish a pressed vs melted difference would be if there were impurities that were not uniform throughout the metal sheet. I would imagine something like taking two snowballs, dying one, and pressing them together. One side of the snowball would be dyed and the other would not. If you melted the two together and re froze them, the dye color would be uniform throughout. I am certainly not that caliber of scientist to know for sure but that's my best guess.
If you really go science you can probably detect the cold welding with a polarising microscope which shows you the grain size and orientation within the material
flexing a soda can tab back and forth about 3-5 times will harden the mount for it and will snap off eventually from getting too brittle because, like cody said, it work hardened
Signs Cody’s got that RUclips money now: he keeps hammering the gold he knows is brittle and in his head he’s like “I can refine an ounce of gold from my feces and fermented urine with a little bit of hydric acid plus I don’t show RUclips my Ferrari I just show them the library”.
I can confirm that the rolling process does work harden the material. Great video Cody!!
100% powdered gold wrapped in 100% gold foil...... joint???? 😂🤣😂🤣👍👍👍
You need a miniature pizza docker - the kitchen tool that is used to poke holes in pizza dough prior to baking that prevents bubbles from forming due to the trapped gasses.
------------ Haha!! I googled 'poky roller tool' and found a Wartenberg wheel! You can use it with your vibrator in the vacuum chamber! ...lmao - I think you'll understand why I'm laughing after you check the pricing from several different sources. It's made of stainless steel and I think it will resolve your bubble issue if you roll it back and forth a few times over sheets of gold.
I love your channel! Thanks for the entertaining education.
...cut a nice line of that gold, roll up a $1000 bill and snort it.
Get gold powder, get gold foil, roll gold foil, snort gold powder using rolled foil, eat gold foil.
Ashton Minden way better. Good plan
The gold "crystal grains" are relatively small so they probably have small slip panes, making them more likely to crack at first. You got the right idea
just wondering.... why do you have a pill maker?
Treavor Miller it could prove quite useful
I actually got it for compressing precious metal powders...
Cody'sLab that’s what they all say...
Why don’t you have one
Amazing that you can do that with powder, you and Nile red should have a Discovery show together, brilliant!
Cody rolling a gold blunt 12 days too late
Congratularions Cody,
Now that you have encountered Cracking, Work Hardening and Heat Normalizing in metals, while hitting them with a hammer on an anvil you have become a blacksmith!
cody makes fresh pasta?
Cody, you should try vacuum welding gold dust! Remove oxidation from air somehow, then put it in a vacuum until it fuses together.
I can't wait for the gardening series
If you get it to work with platinum, then you should try welding them to each other - make a precious metals analog of Damascus steel.
How legal is it to export gold powder? Certain finnish channel has proper tools for pressing it together, or even trying to extrude gold wire :p
artej11 Gold is not very dangerous, so there is no reasons to deal with it.
That's a very good illustration of workhardening, thank you
Anneal and repeat...
Rip Sumrall I think your first comment got the point across.
Cody has sneezed more gold off his anvil than I've ever owned.
Cody as a constant viewer of your videos I love your channel but please get a new blow torch it sounds like a dying old woman
but why do you know what that sounds like?
the police are on their way
Awesome, thank you for all the cool videos. I’m looking forward to seeing you prepare and work platinum.
