Fire Assaying is the oldest and most reliable method of determining gold and silver in rock or concentrate samples. This method is still the industry standard. It is called ''fire'' assay because it involves smelting the sample which has been mixed with lead oxide. Until electric furnaces were available, samples were smelted literally in a fire.
It is a destructive process where the gold is melted with the process of cupellation removing all the impurities and the process of parting separates the silver from gold.
