∙ 14y agoYou can not actually make Plaster or Paris because it is taken from the ground and modified. However, you can make a mock version of it with flour and water. You simply take two cups of warm water and three cups of all-purpose flour and mix them together until you get a paste-like consistency. One set back with this mock version though is that it will quickly set and you won't be able to use it again once it cools.

∙ 15y agoPlaster of Paris is made from Gypsum CaSO4·2H2O. Note that it has two molecules of water (H2O) in its crystal structure.
If you heat Gypsum then waster is released thus 2 CaSO4·2H2O → 2 CaSO4·0.5H2O + 3 H2O (as steam). The 2 CaSO4·0.5H2O is a powder called Plaster of Paris.
When you add water back to the Plaster of Paris powder, then Gypsum is reformed and the powder solidifies.
