Kaolin. Kaolin is a soft, white plastic clay consisting mainly of the mineral kaolinite which is a hydrated aluminum silicate Al Si O (OH) 2 2 5 4. It is formed by the alteration of feldspar and muscovite. Kaolin deposits are classified as either primary or secondary. Primary kaolins result from residual weathering or hydrothermal alteration
