TEXT 2 for questions 8-11

'Cire perdue' which is the French word for 'lost wax' is a process of wax casting used in making metal sculptures. When a model is coated with wax, the solidified wax is encased in a two-layer mold of plaster or clay. It is then melted or otherwise removed from the mold, and metal is poured into the space; where the wax had been. Oh, I almost forgot, after cooling, the mold is broken to free the metal object. This ancient method is used to produce sculptures, jewelry, and utilitarian products such as dentures.
