Inquartation and Parting. The technique mirrors part of the Fire Assay process used in the analysis (assay) of gold. Inquartation involves initially diluting the gold in the refinable material to about 25 (literally quartering the gold) by melting with the appropriate addition of copper or silver granulating the melt so as to generate a high surface area and then treating with nitric acid.
