The details of how to do a fire assay correctly, and the proper fluxes and how they are made, have been written about and published in many books. Fire Assay - Laboratory Design Mishra Introduction Lead metal (Pb) and litharge are used in fire assaying of gold, silver and the platinum group metals (Pt, Pd, Rh, Ru, Ir, Os). Fire assaying has been cited in the literature since the 12th century A.D. Amazingly, it has not changed very much since then either in theory or Size: 1MB. Metals recovered in fire assaying are the metals that emerge from the fusion of the material in a assay furnace, for gold, usually at temperatures of about 2, Degrees F.
