Can you elaborate on where you got that info, with some links?


I could say Soylent Green is people, but I wouldn't expect readers to take me at my word. :-)

Actually the original poster is 100% correct.  All natural clays contain aluminum.  Bentonite is a aluminum phyllosilicate.

Zeolites, which can be formed from the reaction of alkalis on bentonite, are also aluminum silicates.
