Ceramic Clay Fire Assay Crucible For Lab Gold Melting and Precious Metal Analysis

Metals recovered in fire assaying crucible are the metals that emerge from the fusion of the material in a assay furnace, for gold, usually at temperatures of about 2,000 Degrees F. The Fire Assay Method is centuries old, but it is still one of the most reliable methods for performing assays (to determine the metal content of a ore) of ores that contain precious (noble) metals - Gold, Silver and Platinum.
