Mike-
Don't be confused by references to "Fullers Earth"; Bentonite and Fullers
Earth behave VERY differently. Chemical similarity does not make them work
the same way. Bentonite's value is in the behavior with water. Like all
clays, it swells when wet; Bentonite, however, swells a LOT. This is why it
is used to seal ponds and below-grade walls. In water, it forms a
Thixotropic gell.
