What is lost cast waxing?

Answer 1

Lost wax casting. You make something out of wax, jewelry or something similar and attach one or more strips that will act like tubes when the wax is melted out of the mold. You put the piece in a metal container of the right size and pour plaster around it. After the plaster sets, you heat it so that the wax will run out. After this, you melt metal, gold or silver and pour it in the mold or there is a centrifugal caster that forces the molten metal into the mold and gives a better casting. With the mold hot from melting the wax out and the hot metal, you put it in water and the plaster blow off of the piece.
