A process used to purify metals like silver and gold by heating them in the presence of air, which helps to remove unwanted materials.
The ancient method of cupellation was essential for extracting pure gold from ore.
Cupellation is derived from the word 'cupella' (from Latin, meaning a small cup or crucible) and the suffix '-ation' (indicating a process or action). The term refers to the process of refining precious metals, particularly in a small cup-like vessel.
Think of a 'small cup' ('cupella') used in a process ('-ation') to refine metals — that's what cupellation means.
