A material composed of clay minerals, predominantly montmorillonite with minor amounts of other smectite group minerals, commonly used in drilling mud. Bentonite swells considerably when exposed to wa [..]

A clay compound used in the fining process of white wines. The clay binds with solids that might otherwise cause a white wine to become cloudy, removing them from the wine, although some molecules tha [..]

clay-like rock (type of clay); mixed with water, it produces drilling mud.

A natural clay material having thixotropic properties which is used as a basic ingredient for drilling muds and lubricants.

A highly expansive clay. Used in tunnelling technology as a bentonite suspension for slurry-supported methods. Used during tunnelling both as a transport medium for excavated material in the slurry circuit and as a support medium (thixotropic liquid) for the tunnel face.

a clay formed largely by alteration of volcanic ash, which swells in volume when water is added to it—a sodium–calcium–aluminium–magnesium silicate

soil showing very good absorption properties used in the wine making process for binding  of thermo-labile proteins and fostering clarification of wines; it supports sedimentation of dregs 

(n) an absorbent aluminum silicate clay formed from volcanic ash

A colloidal clay, expansible when moist, commonly used to provide a tight seal around a well casing.

A colloidal clay, expansible when moist, commonly used to provide a tight seal around a well casing.

A type of clay used in wine clarification.

A colloidal, hydrated Aluminum Silicate that swells 12 times its dry size when added to Water.

A naturally occurring clay, which is often a major constituent of drilling muds.

A colloidal, hydrated aluminum silicate that swells 12 times its dry size when added to water.

A very fine clay used as a fining or clarifying agent in wine to remove protein, to achieve Heat Stabilization

Called the Clay of a thousand uses. It thickens lotions, stabilizes formulas and purifies skin.

Al2O3×5SiO2×7H2O —Montmorillonitic clay formed from decomposition of airborne volcanic ash. 

A type of clay used in wine clarification.

A very fine clay formed by the alteration of volcanic ash deposits.

Bentonite is an extremely fine clay formed by the disintegration of volcanic ashes, used mainly to increase the plasticity of ceramic clay. It was named by Wilbur Knight in 1898 after the Cretaceous B [..]

A very fine clay, expansible when moist, commonly used to provide a tight seal around a monitoring well. Also used in slurry walls.
