Gold itself does not corrode, but its primary ~s of silver or copper do so - forming very dark chemical compounds - under moist or wet conditions. When a person perspires, fats and fatty acids released can cause corrosion of 14-karat gold, especially when exposed to warmth and air.

The measure for the fineness of gold and gold ~, expressed as a number, Out of 24 parts by weight, of parts of gold in the ~, e.g. '24 carat' means pure gold, '14 carat' means 14/24ths gold in the ~.
