Bentonite is naturally occurring hydrated Aluminum Silicate. It has ability to absorb water several times its weight and give thick tropic fluid. Bentonite is an absorbent aluminum phyllosilicate, essentially impure clay consisting mostly of montmorillonite. There are different types of Bentonite, each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminum (Al). Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. Bentonite is highly plastic, sticky clay used in pottery both in clay bodies and in glazes.
