 A non-swelling Calcium bentonite and our lightest colored Bentonite. Excellent for use in clay bodies, especially in conjunction with Macaloid in porcelains.
Product Details
Note: Sold in 5 lb. increments; Sold in 50 lb. increments for orders 50 lbs. or more.
Al 2O 3.4SiO 2.H 2O
Priced by the pound. A very fine-grained plastic clay of volcanic origin containing colloidal matter. Used in small amounts as an additive to clays to aid in plasticity and in glazes as a suspending and binding agent.

Bentonite can be added to most glazes in amounts up to 1%. Excessive amounts can cause a glaze to become gel like. When used as a plasticizer in clay body, 1-3% is generally used. Bentonite can cause warping and cracking in clays if used in large amounts.
Bentonite should always be added to dry compositions, never to wet. Magnesium bentonites tend to swell, holding large amounts of water. Calcium bentonites are of the non-swelling variety.
**Note: For large or heavy orders that weigh 150 lbs. we will advise you of the approximate freight cost. You will not be charged until we verify shipping costs with you.**
