SMELTING SILVER

explaining how to refine silver for silversmithing. This is the consequence of a rather subtle fact, namely that refining silver is identical to the cupellation of silver for assay, which in turn is identical to the parting of silver and lead in the lead reduction smelting process. The only difference between these three things is one of scale.
