Does anyone have a recipe for making Soft Stone for carving?

Question

A couple of year ago I attended a Stone carving workshop. We made a mixture that consisted of plaster paris, cement and other ingrediants. This mixture was poured into a box and allowed to set. The end result was a soft stone that we then used for carving and making a small sculpture. I've lost the recipe and wondered if anyone could give me one.
