MINERALS KAOLIN & OTHER KAOLIN CLAYS Kaolin is a very common mineral. Kaolin is a soft, earthy, usually white mineral, produced by the chemical conditioning of aluminum silicate mineral. Kaolin is used in ceramics, medicine, bricks, coated paper, as a food additive, in toothpaste, as a light diffusing material in white incandescent light bulbs, and in cosmetics and as a filler in many other applications. Kaolin has even been used for spiritual and healing purposes! It is also being formulated as a spray to be applied to fruits and vegetables to prevent insect damage and infestation. The largest and most common use is in the paper industry. It is the main ingredient in creating "glossy" paper. Other materials such as calcium carbonate (which is an alternative material) competes with Kaolin as the most important source/ingredient for creating shiny paper.
MINERALS MICA The principal use of ground mica is in gypsum wallboard joint compound, where it acts as a filler and extender, provides a smoother consistency, improves workability, and prevents cracking. In the paint industry, ground mica is used as a pigment extender that also facilitates suspension due to its light weight and platy morphology. The ground mica also reduces checking and chalking, prevents shrinkage and shearing of the paint film, provides increased resistance to water penetration and weathering, and brightens the tone of colored pigments. Ground mica also is used in the well-drilling industry as an additive to drilling “muds.”
