Kaolin is made up of individual crystals that form units termed "booklets" of stacked sheets. It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the stone weathering of aluminium silicate minerals like feldspar.In many parts of the world, it is colored pink-orange-red by iron oxide, giving it a distinct rust hue.

Kaolin is termed as hydrous when the kaolin has the bound water molecule. The presence of water imparts specific properties that are useful for certain industrial applications. They are generally used as fillers in the paper, paint, glass and stone industries.
Kaolinite, Calcined - Natural Pigments
Kaolin clay is also used in grounds, such as for painting and for gilding. The kaolin clay can be used in recipes calling for "pipe clay" and mixed with starch or stone to make a thick cream and applied to stone panel or canvas supports for painting. The ground dries quickly and several very thin layers applied one after another to form a ground typical of 19th century paintings.

Journal Ceramics-Silikáty
The strength of cement-burnt kaolin sand specimens depend slightly on the hydration products formed during hydration process of cement. The capability of pure metakaolin in burnt kaolin sand to combine with the most part of Ca(OH)₂ was confirmed by the X-ray diffraction analysis. The Ca(OH)₂ content is reduced due to pozzolanic reaction.
Sand casting - Wikipedia
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.
