Lost wax casting is the process of carving a shape in wax, making a mold of the wax shape, and then casting that shape into metal from the mold. The mold is a negative image of the wax. The wax is melted out of the mold through hollow channels called sprues. Lost wax burnout is the process of preparing a casting mold for the melted metal that will be poured into it.

THE BURN OUT... All the wax in the mold must then be burned out or melted out of the mold in the kiln. The metal is then melted in the kiln at high temperatures in crucibles and poured into the empty mold to cool.
