Kaolinite is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay ). It is produced by the chemical 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. Lighter concentrations yield white, yellow or light orange colors.

· The kaolinite had a specific gravity of 2.64, whereas the 5% and 10% siloxane clay had a value of 1.82 and 1.51, respectively. The reason for the decrease in the specific gravity can be because the siloxane makes the clay particles water repellent, thus making them more buoyant.
