Clay - Wikipedia

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...

Kaolin. During the weathering of intrusive rocks a process known as "kaolinization" occurs wherein the sodium feldspar breaks down into kaolin group minerals – kaolinite and halloysite. Both are hydrated aluminosilicate minerals. Kaolinite (Al 2 Si 2 O 5 (OH) 4 ) occurs as plate-like sheets that commonly appear as "stacked books".
