Bentonite
Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.

All you need to know about Bentonite in Cement Slurries
Compare to dry-blended, when mixed with mix water (bentonite will hydrate totally in 30 min) properties of bentonite are boosted because it absorbs an important volume of water. But, when it is dry-blended with cement and then added to mix water, it does not hydrate completely (Hydration inhibited by Ca2+ ions in the slurry).

Bentonite
The reason for this warning is that when bentonite gets wet, it swells and gels, sticking together and forming clumps that make it tricky to incorporate into the rest of the glaze. If you were to weigh out some bentonite, dump it into a wet glaze and start mixing, the bentonite would clump together, making the glaze lumpy. ... I now add dry to ...
