A common type is Bentonite and most have a plastic state when in contact with water.
Minerals associated with them are aluminium phyllosilicates and the four divisions of them are Illite, Kaolinite, smectite, and Chlorite. A common type is Bentonite and most have a plastic state when in contact with water. The neoformation of them occurs through the chemical weathering of rocks and soil. On the Wentworth scale, they have a grain size less than 4 micrometers, which makes them smaller than silt and all others on the chart. For ten points identify this type of material which can be turned to ceramics in a kiln.
