Bentonite Powder
Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.
Bentonite is a highly colloidal clay mineral decomposition of volcanic ash, having the ability to absorb large quantities of water and to expand to several times its normal volume
