What is Bentonite?

The main constituent, which is the determinant factor in the clay''s properties, is the clay mineral montmorillonite. This in turn, derives its name from a deposit at Montmorillon, in Southern France. Bentonite is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite.
