KAOLIN: Kaolin is a soft, lightweight, often chalk-like clay that has an earthy odor, and in Florida is generally light in color and associated with large amounts of quartz sand. The state reserve of kaolin occurs in large deposits in the east-central part of the state from southern Clay County to northern Highlands County.

اقرأ أكثرKaolin is a form of clay. Clays are formed by the weathering of rocks. Weathering of rocks can be classified as physical or chemical process. In case of kaolin, the chemical reaction between water, carbon dioxide and feldspar (rock) gives rise to kaolin clay deposits. Feldspar (Rock) + Water + Carbon Dioxide (Gas) -> Kaolin (Clay)
