plaster of paris[pop] is calcium sulphate hemihydrate [CaSO4.1/2 H2O].on exposure to moisture forms gypsum[CuSO4.3/2 H2O],which hardens the pop
gypsum plaster does not burn or catch fire. It is essentially rock.
Get a mould and plaster. Pour water into the plaster and mix. Pour the plaster into the mould and wait for it to dry. Once it is dry carefully take the plaster out of the mould and paint. Note:To get air bubbles out of the wet plaster, gently hit the mould.

All that needs to be done is to grind up the gypsum and heat it to 300 degrees F. Gypsum contains water, and the heating drives it off.
There is no specific element in plaster that produces. The chemical reaction that results when plaster is mixed with water is what produces the heat.
Stockists are dealers who agree to sell a number of products on behalf of the manufacturer. Stockists are also called suppliers.
If there is water in it you can heat it.

Yes, so the plaster will need some type of water-proof coating. If you are carving something from a plaster block, moulding something out of plaster, or even using a pre-made plaster object, the only way it will not slowly dissolve in the water of the snow globe, is to make sure it is totally covered in some type of water-proof finish. I'd use a minimum of 2 coats to make sure. If there is even a small break in the finish for the distilled water to get under, your finish will begin to peel and the plaster will break down there.
Plaster of Paris is a classic exothermic reaction. The gypsum when heated to 150 degrees dehydrates with 75% of water content escaping as vapor. When water is reintroduced it resets the crystal lattice and gives off heat.
Yes, but not directly. The hydration of calcium sulfate into gypsum is a molecular change that requires significant heat (150° C, 300° F) to again dehydrate the powdered plaster. (When dry plaster is mixed with water, it releases heat through crystallization.)
