Complete Fire Assay Laboratory by Cupellation « Gold

Introduction to Assaying The assaying process is a necessary step to determine the quantity of precious metals present in an alloy. Cupellation is one operation of the assay process in which a sample of gold, wrapped in lead foil, is melted in a special crucible known as a cupel: this cupel has the capacity of absorbing the non-precious metals contained in the gold alloy.

Technical Note

Too large a volume in the fire assay crucible will result in boil over and subsequent loss of sample, as well as damage to the furnace floor. THE FIRE ASSAY CHARGE WEIGHT All fire assay texts quote an “assay ton” (approximately 30 grams) as the charge weight to be used for a fire assay determination on a simple sample matrix.
