Bentonite is different from other clays because of how strong a "pull" it has. If you've ever used different types of clay masks before, you may have noticed how intense the bentonite clay felt versus the others. That intense pull is what makes this soap so effective at deep cleansing pores. It gives skin a little mini-detox of sorts.

The hardness is greater than orthoclase and less than peridot, or about 6 to 6 1/2, and the specific gravity is 3.64 to 3.67. Benitoite crystallizes in the trigonal division of the hexagonal system. The common forms observed are the base c(0001), trigonal prisms m(1010), and n(0110), and the trigonal pyramids p(1011) and π(0111).

Bentonite also increases the hardness of a glaze after it dries. If your glaze is really powdery after it dries, which is often due to a lack of clay, adding bentonite will help to harden and bind the glaze layer. Since bentonite has a very high shrinkage rate and a high iron content, I don't recommend adding much more than 2% to a glaze recipe.
Details
Bentonite is a mixture of clayey minerals, in which smectite is the main mineral and proved to be the most important one for swelling. The structure of smectite like montmorillonite is composed of two structural units, the silica tetrahedron and the alumina octahedron. These units are interconnected and extend to form layers only about 10 Å thick.
