It is made from a soft rock called gypsum.

The gypsum is heated to about 1500C to remove its H2O (water) content. It becomes a dry powder, with the chemical name gympsum hemihydrate or, more accurately calcium sulfate hemihydrate. CaSO4.1/2H2O

Does plaster of Paris burn?

No Plaster of Parisis is made by calcining gypsum, a process which involves exposing the gypsum to very high temperatures to create calcium sulfate and then grinding it into a fine white powder. Gypsym does not burn and it can be used to fireproof things. The material itself is definitely non-combustible. However, it can CAUSE burns (although not chemically as lime might). When Plaster of Paris is mixed with water, the reaction is strongly exothermic. It gets warm. In large quantities it gets hot. In 2007 a school girl immersed both hands in a bucket full of wet Plaster of Paris as part of an art project. After suffering third degree burns, she had to have both thumbs and six fingers amputated.
