The product you are referring to is a very finely ground powder as people consume the food grade type (which is what I have). You really can't compare the 2 products.
STS & Oildri goes through a process of drying, shaped, sized, and firing (like pottery but not exactly) so they don't dissolve in water. Bentonite & montmorillonite clay are the same stuff.
The powdered form has more surface area than the baked form.
