I also use bismuth, made own bone ash cupels, but was disaster a bit... 🙂 Under cupel I use terracota dish with magnesium oxide to avoid sticking. You did everything right, just not much gold and silver there...
Thanks, I still don't know where the dark liquid stuff came from when my first cupel with gold cracked and leaked because I only added bismuth and no flux.
@@MetalScrapLabHmmm... probably oxides, that were created in the ceramic dish, as liquid bismuth leaked, was oxidised in the dish, but liquid oxides had no way to be absorbed, so stayed as they were, as black liquid... For that case I have magnesium oxide powder under cupel, if things go south, MgO catches whatever...
To all beginners (not this guy, he's smart and knows already) start with 2-3 grams of 10k gold scrap. Then you can see the process and get enough gold back to know you didn't fail. Most guys get 0.1 gold at the end orless because they do to little ewaste, and they dont see the 0.1gram and assume they failed when they really didnt. If you do enough to see the process start to end, youll learn a lot! This dude knew there wouldnt be much gold to see, he did it right (not my way though) and knew it was to little to expect much gold.
@@MetalScrapLab yes. Apparently it's the spattering of the bismuth that spreads the bead all over the cupel. Lead didn't splatter as much. Maybe lowering the temperature would help also. Lead Oxide needs 1800F or so to drive, where bismuth is around 15-1600F

Interesting. Thanks.
@@frantiseklaluch6605 nice idea
The cost of electricity to do this must outweigh the value of the end product.
No it doesnt
+ the time and Bismuth
Well done for giving it a go. Obviously not the most profitable endeavour but I commend your attempt
From what I understand, you should turn your furnace down to like 1000’ with bismuth. It splatters your PM everywhere when you get it too hot
It would take buckets of that just to get enough to weigh. It is the fools Gold of E-waste.
Theres actually alot of gold in those

what a cool Grinder😍
Witam witam i pozdrawiam serdecznie z Polski 🇵🇱👍👍👍
Humm, its gone a take time before we retire with this gold !
Bismuth is not as good as lead for cupelling. MBMM Jason found losses with bismuth compared to lead in the same process for both.
Interesting. I picked up bismuth as lead replacement from Jason at MBMM.

Where do you find one of those grinders?
No black or dark nuggets? Maybe the plastics is on the gold( thought it was borax. You need a substantial amount of material to get a gram
Good video, check the splatters in the oven
I don't know if that was even worth the trouble.
If he did it in a different way its definately worth it
@MetalScrapLab out got another follower nice experiment, looks like it worked well🤗
So, after expenses and paying taxes, how much do you make an hour? I'll bet it's not enough to pay the bills.

this is a very poor gold material and in fact much more of it is needed to get any result
Not true
