I need some help with the process of this video

Hello friends If my English rules are not good, I apologize This clip was uploaded to YouTube by owl Tech
He's in the forum but I don't know what his username is If you see this thread, I have a few questions
1) What is the metal of the plate where the molten step is carried out with lead and silver?
2)How is the heating system designed and built under it?

Watch "Palladium from ceramic capacitors (MLCCs) - recovery and refining" on YouTube

stainless steel sheet, and the design of the forge is pretty much the same: http://www.mooseforge.com/Forges/forges.html

Thank you very much for your attention
What kind of steel do you use? (Steel 304 or 305 or 321 or 401 or ...) I ask this question because the melting temperature of steel should be higher than the boiling temperature of lead and the melting temperature of silver, right?
Doesn't steel react with other materials (borax, carbonate, lead, silver and gold) because of its alloy?
You use coal or ordinary charcoal?

Tnx

Hi.
I'm a bit surprised.
Won't the Lead alloy with the Steel during this process?
I know Silver will not alloy with Steel/Iron to any significant degree, but what stops the Lead?

 

[Owltech]

"While lead is often added to steel alloys, it is actually not an alloying element itself. When added to steel, lead does not join with the carbon, iron, and other elements. Lead is actually not soluble in steel. Rather, lead remains in the steel in the form of inclusions. Lead also has almost no impact on the mechanical properties of the steel, but improves the machinability of the steel because it acts as a lubricant between the cutting tool and the steel. Welding steel with lead additions almost always results in cracks and is not recommended.

Lead is added to steels that will undergo machining but not welding. AISI grades of steel that contain lead typically have an “L” designation. Common alloys include 11L18 and 12L14"

Thanks for the answer.
I did expect lead to behave as Tin more or less ;-)
Should have turned to Google yet again
