dc.descriptionThe Department highly recommends analysis of samples by the fire assay method to determine precious metal content. Fire assaying, in use for thousands of years, still stands the test of time. The following summary is taken from “Assaying,” by Jim Steinberg in Mining Artifact Collector. The article was written from a historical viewpoint, but the process is the same as the fire assaying of today except for the use of electronic balances, mechanical pulverizers, and so forth.
