[See Cupel.] The act or process of refining gold or
silver, etc., in a cupel.
&fist; The process consist in exposing the cupel containing
the metal to be assayed or refined to a hot blast, by which the
lead, copper, tin, etc., are oxidized, dissolved, and carried
down into the porous cupel, leaving the unoxidizable precious
metal. If lead is not already present in the alloy it must be
added before cupellation.
