Bentonite is a geological extract found freely in its natural state. Bentonite is formed out of volcanic ash. It is a form of clay that consists of a primary mineral called montmorillonite that gives it its properties. Montmorillonite is a dual-layered, dual-dimensional mineral that has aluminum and silicate. These minerals give bentonite a layer of cards that look like crystalline packets and are called platelets. Bentonite is identified and used in this form. Mined from the earth's sedimentary layers, it is highly concentrated in the Midwest and Canada. In fact, it is estimated that Wyoming's geology houses more than two thirds of the world's bentonite. Bentonite can be calcium-based; potassium-based or sodium-based. Its properties in each of these states are varied and unique.
Physical Properties
As a form of sedimentary clay that is formed out of volcanic ash, Bentonite has a highly viscous, gel-like structure. This makes it ideal for use in many industries. It is primarily used in its physical state in the wine industry. Because of its physical properties, it is a useful binder in wine. When hydrated, it can change its molecular and electrical properties. This makes it porous, and useful as a binding agent.
Chemical Properties
Bentonite is a source of many useful chemicals. As a mineral, it is primarily composed of silica, which makes up almost two thirds of its substance. It also has smaller proportions of other minerals in varying ratios: aluminum, 18.1 percent; calcium, 0.04 percent; iron, 3.5 percent; magnesium, 1.7 percent; moisture, 7.8 percent; potential hydrogen, 8.3 to 9.1 percent; potassium, 0.01 percent; sodium, 2.3 percent and titanium, 0.02 percent. These minerals can be extracted from bentonite and used in various applications.
Healing Properties
Bentonite is used as a base in laxatives and many other medications. Since it is found deep in the earth's layers, bentonite is used for clay baths designed to purify the body of toxins. Since it is absorbent, it is also used to soak poisons from the body. Bentonite as a poultice on wounds has been in existence for a long time as a therapy. When used in this form, it is very useful in treating bug bites.
