Difference Between Kaolin and Bentonite Clay

Aug 21, 2018Kaolin and bentonite are two forms of clays that are rich with aluminium and silica minerals. The difference between kaolin and bentonite clay is that Kaolin forms as a result of weathering of aluminium silicate minerals such as feldspar whereas Bentonite forms from volcanic ash in the presence of water.
