Item details

Bentonite 325 Mesh 1 lb.

Bentonite is a special type of clay. In ceramics it's used as a suspending agent, viscosity increasing agent, binder, plasticizer and emulsion stabilizer. It's useful in both clay bodies and in glazes. There are several different types of it which exhibit slightly different properties.
It can be used in water (or oil) based paints for rheology modification and also in liquid polymers.
The fact that it's relatively inexpensive makes it attractive alternative for many applications.
Concrete modification is another area that's been researched. It's used as a tool in concrete construction where it can be a flowable hydraulic material used for in balancing forms into which concrete is poured.
It has many other uses, and many revolve around its abiltiy to swell greatly when it comes in contact with water. I'll have first hand experience with this: if you have a pond that's leaking and you can spot the general area where it's leaking, buy 4 or 5 bags of bentonite. Wade or boat out to where its leaking (inside the pond), throw your bags of bentonite in the area of the leak, perhaps ripping open the bags when they're in place, or just stomp on them (this requires some underwater labor, of course), and if you're lucky, by the next day you'll see the leak slowing. You many have to repeat. It worked for me.
You can probably also infer that bentonite absorbs water very well. If you have cats, the presence of bentonite in the cat litter you buy is why it's so heavy (it may just say "clay" or something similar in the ingredients list). It's also used a lot in the oil well drilling business.
The Wiki article on bentonite is good and into much more detail on the different types of bentonite:
https://en.wikipedia.org/wiki/Bentonite
"Sodium bentonite expands when wet, absorbing as much as several times its dry mass in water. Because of its excellent colloidal properties, it is often used in drilling mud for oil and gas wells and boreholes for geotechnical and environmental investigations. The property of swelling also makes sodium bentonite useful as a sealant, since it provides a self-sealing, low permeability barrier. It is used to line the base of landfills, for example....Bentonite is used in drilling fluids to lubricate and cool the cutting tools, to remove cuttings, and to help prevent blowouts. Much of bentonite's usefulness in the drilling and geotechnical engineering industry comes from its unique rheological properties. Relatively small quantities of bentonite suspended in water form a viscous, shear-thinning material. Most often, bentonite suspensions are also thixotropic...Bentonite has been widely used as a foundry-sand bond in iron and steel foundries. Sodium bentonite is most commonly used for large castings that use dry molds, while calcium bentonite is more commonly used for smaller castings that use "green" or wet molds. Bentonite is also used as a binding agent in the manufacture of iron ore (taconite) pellets as used in the steelmaking industry. Bentonite, in small percentages, is used as an ingredient in commercially designed clay bodies and ceramic glazes. Bentonite clay is also used in pyrotechnics to make end plugs and rocket engine nozzles...Bentonites are used for decolorizing various mineral, vegetable, and animal oils. They are also used for clarifying wine, liquor, cider, beer, and vinegar. Bentonite has the property of adsorbing relatively large amounts of protein molecules from aqueous solutions. Consequently, bentonite is uniquely useful in the process of winemaking, where it is used to remove excessive amounts of protein from white wines...Bentonite is used in a variety of pet care items such as cat litter to absorb the odor and surround the feces. It is also used to absorb oils and grease."-
