"Cupellation" Pronounce,Meaning And Examples

"Cupellation" Meaning

Cupellation is a metallurgical process in which a metal, usually silver, is refined by melting it in a cupel, a porous earthenware or ceramic container, with the presence of air and a flux, typically silica or borax. The impurities in the metal, such as lead, copper, and gold, are oxidized and removed as fumes, leaving behind a refined and pure silver. The process has been used for centuries to produce high-quality silver products, including coins, ornaments, and other decorative items.
