Cupellation and the Birth of Precious Metal Refining
The cupellation process is one of the best ways to extract these precious metals. It starts with the construction of a cupel, a small bowl that will contain the alloyed metals throughout the process. The cupel must be made of porous, calcified material so it can absorb lead without causing a reaction. The alloy is placed in the cupel and heated.
