Cupellation. Cupellation is the technique that forms the first part of the fire assay process, in which lead is added to the unrefined gold material. The mixture is heated in air to between 1,830°F and 2,010°F (1,000°C and 1,100°C), at which point the gold-containing metal dissolves in the lead.

Gold panning is a simple and rudimentary form of this process. Physical sifting and separation, at best, are just initial steps. To attain a high level of purity, there are only two options: using heat or chemicals.
