I was at a workshop that included cob. They had had trouble procuring clay. We had bentonite cat litter - fresh- for our use. We had to soak it to dissolve the clay.
In later years, I bought cat litter to use as clay. The stuff I had bought turned out to be particles bigger than sand and finer than gravel… pretty much cat litter granule size.
When I soaked, the clay dissolved and I was left with this other stuff….
Try to buy a sample before buying a large amount!
There is a pathogen associated with cat feces that is a mostly a threat to pregnant women. Toxoplasmosis. Can cause birth defects and miscarriage.
I think it’s a very bad idea to utilize used cat litter anywhere there could be possible future contact with humans.
Many hardware stores and most feed stores / farm supply sell bentonite in 50 pound bags.
Building suppliers selling rock, gravel, sand , roadbase etc often have material for sale by the truckload or yard. I get samples of what’s available and test for clay content…. then order it delivered … for cob and adobe building and soil improvement.
Best luck: satisfaction
Greatest curse, greed
