Bentonite is a very reactive clay that shrinks or swells markedly in response to the removal or addition of water. Bentonite consists mainly of smectite minerals (swelling or expandable clay), commonly formed by the decomposition of volcanic ash or sometimes from other igneous or sedimentary rocks.
