[TowerTalk] Bentonite ?

I have seen several references lately to the use of the Mineral Clay
"Bentonite" used in tower and antenna work. I have a couple bags of it, and
have used it as a suspension agent in Ceramic glazes, and as a
Viscosity and shrinkage control in clay bodies. I have seen it used as
drilling "Mud" in oilwell drilling, as liner conditioner in ponds, and as a
sealer to correct leaking basements.
Almost all these applications derive from the simple fact that , like most
clay, it swells when wet; it's particular feature is that it is EXCELLENT
at doing it. (ie, it swells a LOT)
None of what I have experienced or read tells me of anything else inherent
in its properties that applies to Antennas, and I am very curious.
Does anyone have any references they can pass on?
