The clay test determines the amount of active clay, indicating the base exchange capability of bentonite. Procedure - The amount of exchangeable ions present is determined by replacing these ions with dye. Significance - Clay that still has the ability to exchange ions will contribute to green, dry and hot properties of molding sand mixes.

After advancing the boring, setting the screen/riser and sand pack, the vertical driller usually pours dry bentonite chips or pellets into the annular space between the vertical well and formation. The vertical driller then adds water to hydrate the bentonite, creating a very effective seal as the bentonite swells (or "yields").

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.
