A relative newcomer, this amazing material is the hardest, densest gypsum cement and requires only 22 parts water to every 100 parts Drystone. Mechanical mixing is an absolute must with this material. The name is derived from the fact that it is essentially dry when it is de-molded and requires no oven drying. Parts can be decorated and shipped on the same day as the castings are made. Surface may be polished with wax to give a stone like appearance. May also serve as a good substitute for USG's discontinued Tufstone!
