  • Kaolin | Imerys

    Kaolin is formed when the anhydrous aluminum silies found in feldspathic rocks, like granite, are altered by weathering or hydrothermal processes. The process which converted the hard granite into the soft matrix found in kaolin pits is known as 'kaolinization'. The quartz and mica of the granite remain relatively unchanged whilst the feldspar is transformed into kaolinite. .
