- Assay / Assayed - Assaying is the testing of a metal, most commonly silver and gold to determine its ingredients and quality. In Britain, once an item of silver or gold has been assayed, a mark is stamped on it, certifying its purity. Known as hallmark, it derives its name from the Guild Hall of the Goldsmiths' Company, who recieved its Charter in 1327 giving it the power to assay and mark articles of gold and silver.
