Bentonite

Volcanic Materials in Commerce and Industry. Jonathan Dehn, Stephen R. McNutt, in The Encyclopedia of Volcanoes (Second Edition), 2015. 5.1 Bentonite. Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange …
