This was the basis behind using it on a dirt track. It works great on dirt IF it is completely saturated as calcium chloride hexahydrate. If not, it will draw moisture out of the clay and into the lattice. Then the clay gets dry and hard. The other problem is that CaCl2 mixed with water is an exothermic reaction. The heat will drive off some of the water.
I don't see how it's illegal since they use it during the winter on roads to prevent icing. Maybe it's illegal for anyone but the gov't to use

I think it does the same thing to the mozzarella cheese that we package. It draws the moisture out of the cheese to make it stronger or harder in body and therefore makes it easier to shred and package than a softer type cheese. Whatever it does it sure melts nice and makes one helluva nice topping on a pizza.
