Most commonly, fine gold is 999. This is the gold most commonly referred to as 24 karat gold, although technically 24 karat gold is pure. However, as this is difficult to achieve outside of a lab environment, 999 gold is generally considered close enough. Gold manufacturers are legally allowed a halfkarat tolerance in making gold products.

The extraction of gold by mercury is described by Biringuccio in his treatise (which was published in Italian in 1540), and had apparently been a secret art for some time previously. Among other ancient methods of amalgamating ores, the tina and cazo systems may be mentioned. In Norway and Chili, however, the working was not continuous.
