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. The weight of the gold alloy sample is usually about 250/1000. Although this is the most ancient method to determine the purity of an alloy, assaying by means of cupellation gives greater precision than more modern methods (fluorescent or x-ray spectrophotometry) and is considerably less expensive.
NOTE: The standard assay laboratory can carry out approx. 40 assays per day. It is possible to increase this number by using a mutliple assay hood (for example model CS/D) in place of the CS/D unit and by purchasing a larger cupellation furnace (for example, model FCOPP/B)
