Bentonite consists chiefly of crystalline clay minerals belonging to the smectite group, which are hydrous aluminum silicates containing iron and magnesium as well as either sodium or calcium. Two types of bentonite are recognized, and the uses of each depend on specific physical properties.
Foundry sands typically use between 2% to 10% bentonite by weight of sand as the binder. Add the bentonite to the wet sand and mix throughly.
