How Do You Mix Plaster Of Paris?
Plaster of Paris has been used for centuries as an inexpensive, durable and easy-to-use art and craft material. It can be use to pour sculpture castings and as a mold-making material. Plaster of Paris is a dry white powder, mainly comprised of gypsum, that is added to water to form a thick liquid mixture. The liquid plaster can be poured, brushed or applied with a spatula into a mold or onto sculpture. The water and plaster, after mixing, undergo a chemical reaction that causes the mixture to harden. Following the steps in this article will ensure success in mixing plaster of Paris. Read the directions and safety precautions on the packaging of the plaster material; some manufacturers of hobby materials include additives to the plaster that affect the mixing ratio.

Always add the plaster to the water; do not add water to dry plaster powder.
