You can buy it in 50,60, and 100 pound sacks, singly or by the pallet load,
and in bulk by the truck or car(train) load. Anybody who deals in bulk
portland cement will typically have it. Why, the Vice President of the
United States used to have a job loading 100 lb sacks on railroad cars,
although I suspect calling him for supply suggestions might not be
appropriate. ( I ran across a quote on whitehouse.gov when I was googling
Be aware that there are a lot of grades of bentonite around, depending on
the application. If you're using it for grout or as an admixture for soil
or concrete, you can get by with a different kind than if you're using it
to clarify wine or make biological weapons.
