» Characteristics of Gold
This system breaks down the purity into thouhs in order to label the "fineness" (purity) of the gold sample. For example, a specimen that contains 90% gold and 10% impurities would be labeled .900 fine; 88% gold content would be labeled .880 fine; 75% gold content would be indicated as .750 fine, and so on.

ANC's head in the sand over our future
The Chinese make about 90% of the silicon wafers that, placed between transparent panels, will generate a charge if light is focused on it. You have to heat it to around 2,000°C. The oxygen in the "rust" then reacts with the carbon in the coke you're heating to make a residue that is then distilled to a fabulous degree of purity.
