Our white kaolin clay is from deposits in Texas, USA and is heat treated to remove some portion of its hydroxyl (OH) composition. Calcined kaolin is produced by heating ultrafine natural kaolinite to high temperatures in a kiln. The calcination process increases whiteness and hardness and alters the size and shape of the kaolin particles.
