argile kaolin calcine is not only versatile, but also incredibly mild which makes it especially beneficial for those with sensitive or dry skin types. It is a super effective face cleanser and gently scrubs away dead skin whilst absorbing impurities from pores. This not only detoxes skin, but makes pores appear smaller and leaves the skin feeling incredibly soft.

Kaolin enhances paints' and coatings' appearance, offering increased gloss and sheen control and enamel holdout. Kaolin is also ideal for enhanced whiteness and brightness. For specific paints and coatings, kaolin is also excellent for giving products additional properties like improved corrosion and scrub resistance.

Calcined kaolin has an important use in ceramic glazes. Al 2 O 3 is essential to the chemistry of the vast majority of glazes and its most readily-meltable natural supplier is feldspars, however they most often oversupply KNaO in providing the needed Al 2 O 3. Raw kaolin is an ideal second or even primary source of Al 2 O 3.
