Bentonite clay is also rich in minerals like silica, calcium, magnesium, sodium, iron, and potassium. A good quality bentonite clay is grey or cream in color — steer clear of white "bentonite clay" (since it's likely not actually bentonite clay). It is very fine, has a velvet feel, is odorless and non-staining.

Bentonite clay is formed from ancient volcanic ash that was once exposed to seawater, at which point it absorbed a whole lot of minerals. It's often sourced from ancient seabeds (that are now dry land), and its name comes from Fort Benton, Montana—the location of the largest known deposit of bentonite clay. It's also called …
