Bentonite is used in the molding processes of metal casting. When mixed with foundry molding sands, Bentonite forms a pliable bond with the sand. Impressions are formed in the bentonite/sand mixtures, and then molten metal is poured into the impressions. Upon completion, the bentonite/sand mold is broken away from the casting face and reused.
