Most of the fullers earth I've read about is a type of smectite clay.
Smectites in general have a fairly high cation exchange capacity and some
(like bentonite used for clumping cat litter) have a well developed
tendency to swell when they adsorb water, which the do very well.
Profile would probably be a calcined clay product. It wouldn't have all
the properties of the original clay, but it would tend to stay together
underwater, which the original clay might not.<<
That would explain I guess why it seems very light in the water and retains
O2, giving off bubbles for weeks after putting it in the tank...??
