Bentonite - A processed clay material composed principally of the mineral montmorillonite. It has a great affinity for fresh water and when hydrated will increase its volume more than seven times. Water/bentoninte suspensions are essentially impermeable.
A very fine clay, expansible when moist, commonly used to provide a tight seal around a monitoring well. Also used in slurry walls.

A naturally occurring clay containing appreciable amounts of the clay mineral montmorillonite. Mined extensively in Wyoming, the Dakotas, Mississippi, Texas, and California.
A colloidal clay (montmorillonite) derived from volcanic ash and used as a binder in compounded sands for the foundry for increasing both green and hot strength.

A type of clay used as a clarifying or fining agent for the protein stabilization of wine. It is mined mainly in Wyoming in the USA and if it is used correctly, it has no effect on the bouquet and flavour of the wine.
Very fine clay used to heat stabilize and clarify a wine. To use it, boil a small amount of water, add the bentonite and stir until dissolved. Then allow to cool slightly. Lastly, add the mixture to the wine and allow to set for several day. The bentonite will cling to particles and help clear the wine.

A soft, plastic, porous, light-colored rock composed essentially of clay minerals of the montmorillonite (smectite) group plus colloidal silica, and produced by devitrification and accompanying chemical alteration of a glassy igneous material, usually a tuff or volcanic ash.
Colloidal clay, naturally occurring hydrated aluminum silicate. Bentonite is used to thicken latex, and as compounding material for natural rubber.
An inorganic fining or clarifying agent made from diatomaceous earth. Learn how to prepare bentonite for addition to your wine by reading Tom's article above.
material composed mostly of the clay mineral montmorillonite. This rock has great ability to absorb water and swell.
A natural clay that is an effective skin clarifier. Takes its name from Fort Benton where bentonite deposits are found. Used in facial masks.
Substance produced from Montmorilonite clay and can be used as a fining agent to clarify must and wine
mineral-derived Obtained from volcanic ash, bentonite clay is highly absorptive. It is in our Clay Mask to help draw impurities from the skin by absorbing excess dirt and oil. It also is a natural thickener for the product.
An aluminum-silicate clay originally found around Fort Benton, Wyoming, Bentonite is commonly used to fine white wines and, to a lesser degree, red wines. The negative charge associated with Bentonite attracts a variety of suspended solids in wine causing them to precipitate which typically results in a more clear and stable wine with reduced off odors and flavors. Prior to addition, Bentonite should be hydrated with a small amount of warm water. The wine should be racked off the finings within two weeks of addition.
A colloidal clay, expansible when moist, commonly used to provide a tight seal around a well casing.
A naturally occurring impermeable clay that expands when wet. Used as part of the lining system at landfill sites.
rock comprised of altered volcanic ash and composed essentially of montmorillonite clay; capable of absorbing 7-10 times its own weight in water.
Type of clay derived from weathered volcanic ash that expands when wet; commonly used as well drilling mud and annular seal.
(3) a clay mineral formed from the decomposition of volcanic ash. Commonly bentonite can readily absorb or adsorb water.
A highly plastic clay originating in the decomposition of volcanic ash. Up to 2% can be added to all bodies to improve plasticity. Up to 3% can be added to glazes and engobes to help keep them in suspension. It is best to add the bentonite to the water and mix thoroughly before adding it to the batch.
A clay with great ability to absorb water and which swells accordingly.
A material composed of mineral clays, the most significant of which being Montmorillonite
soft clay, formed by the weathering of volcanic ash, with the unique characteristic of swelling to several times its original volume when in contact with water.
a rock layer that results from volcanic ash falls useful in time correlations
a purified natural clay that is used in fining white wines for the purpose of correcting heat instability. When stirred into a white wine, the Bentonite particles quickly glom onto the larger molecules of protein in the wine, collecting them as the Bentonite settles to the bottom of the wine tank. Later, the act of removing the Bentonite from the tank by racking or filtration removes the excessive protein from the wine. It was these larger proteins in the wine that had caused heat instability, so Bentonite treatment corrects the original heat instability of the wine. Bentonite is never used for red wines because the red pigments of wine tend to stick to the Bentonite also. Heavy Bentonite use in red wine would effectively destroy the red color of the wine. richardgrantwine.com
Clay formed from volcanic ash which can absorb large amounts of water and expands to many times its normal volume. Used to retain the sides of excavations in wet, unstable soil.
This white clay found in the Midwestern United States and in Canada draws oils, toxins and impurities from deep within the skin.
The mineral montmorillonite, a magnesium-aluminum silicate. Used as a treating agent, also, as a component of drilling mud, and in greases.
This white, moisture-absorbing clay is skin-softening and will help exfoliate and draw out oils and impurities from the skin. Used in blemish masks, bentonite is reported to draw toxins out of the skin.

A type of clay derived from volcanic ash and used as a paint pigment.
A clay that is used as an absorbent in cosmetics.
a type of clay often added to drilling fluid because of its swelling properties when added to water.

clay mined in the United States primarily used for clarifying (fining) of wine.
A type of clay used in wine clarification.
A porous clay that expands to many times its dry volume as it absorbs water. Bentonite is commonly found in many cosmetic foundations and may clog pores and suffocate the skin. Bentonite is used by fire fighters to suffocate forest fires by eliminating the oxygen available.
Special "clay" which acts as a "fining" agent for the wine, in order to avoid the formation of a sediment in the bottle.
(also known as Kaolin): Also known as "china clay". Generally, these clays are used in facial masks to absorb excess facial oil. Although, it can dry-out the skin if used too often, and in some cases it may even clog the pores.

Used in clay packs and masks for facials. Volcanic ash
A clay composed of montmorillonite, hectorite, smectite or impurities. After purification it is suitable for use as a thickener in lubricating greases.
Bentonite is an absorbent aluminium phyllosilicate generally impure clay consisting mostly of montmorillonite, (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2·(H2O)n. Two types exist: swelling bentonite which is also called sodium bentonite and non-swelling bentonite or calcium bentonite. It forms from weathering of volcanic ash, most often in the presence of water.
