Cupellation Furnace by elman
Cupellation furnaces series  are used in the assay process of precious metals alloys. Cupellation is a procedure with the purpose to remove all non noble metal from the alloy to test. Top cast cupellation furnaces are provided with a built-in electromagnetic induction generator for the heating of the muffle. This leads to ultra fast work cycles and high energy efficiency.
Cupellation is conducted in a muffle furnace.The fire is lighted, a little bone-ash is sprinkled on the floor of the muffle to prevent its corrosion by litharge in case of the upsetting of a cupellation, and the cupels introduced as soon as a bright red heat is attained. The cupels are cleaned by gentle rubbing or blowing before being charged-in, and are again cleaned with bellows before the lead is charged-in. They are placed in the furnace one by one, or, better, charged-in together on a tray
