Kaolinite is a type of clay mineral that is formed through the chemical weathering of aluminum silicate minerals like feldspar. When these minerals are exposed to weathering processes like rain, wind, and heat, they break down and release aluminum and silica ions. These ions then react with other minerals and elements in the surrounding environment to form kaolinite clay.

Kaolinite can also be formed from the inheritance of clayey, sedimentary soil parent materials. In this process, pre-existing kaolinite clay particles are carried by water and deposited in a new location where they are further weathered and altered by the region.

Although white in its purest form, Kaolin Clays are extremely colorful and can come in a rainbow of shades depending on how iron oxide and various other minerals react to it over millions of years of weathering depending on the region.
