Lost wax, or investment casting, is one of the oldest methods for casting items from metal. Basically, a wax model is made and then it is surrounded (invested) with clay or plaster. This is then heated to melt out and burn away the wax, leaving a cavity that is the exact shape of the original model. The wax is lost, thus the term lost wax. Lost wax is used for making jewelry, decoration pieces, gods and goddesses. The lost wax or cire-perdue process is the traditional method of bronze casting . It has been around for at least 5000 years.
