Cupelling or Cupellation.
Alchemy!? Well no. I have not yet been able to turn lead into gold. Although the Cupel process sure looks like it. This video series is all about melting, smelting, cupelling, roasting, and fire assays. Equipment, chemicals, processes and flux will all be covered. I will be learning right from the basics so this series should be a good way for the armature gold prospector to learn. I will be using the KK8 and Kwik Kiln 2 smelting and cupelling furnaces provided to me from "911 Metallurgist" and "Gold Processing Kilns" Both links below.
In this video we explore the cupellation process. Cupelling is taking the lead prill made during smelting, and heating it in a pressed bone ash cupel. This cupel will absorb the lead (or at least lead oxide) but will not absorb the precious metals. So in the end you will be left with a bead of gold, silver and platinum sitting in the cupel which is now full of lead.
