Lost-wax casting in some cases called by the this french language name of cire perdue (from the Latin cera perduta) would be the process by which a metal (such as silver, gold, brass or bronze) sculpture is cast from an artist's sculpture. Intricate performs is often achieved by this method, mainly based to the carver's skills. In industrial uses, the contemporary process is called investment casting. An ancient practice, the process today differs from foundry to foundry, but the steps which are usually used in casting small bronze sculptures inside a contemporary bronze foundry are generally quite standardized.

Lost wax casting is a process that uses molds to kind liquefied metals. during this process, liquefied metals are shaped into higher quality products that are designed of a lot of completely different types of metals. because lost wax casting often results in tough finishes, additional methods may be required to get rid of burrs from the end products.

During lost wax casting, a extraordinary wax is injected into a metal die, producing designs that are compiled into a cluster close to a wax runner system. after the pattern is coated with layers of refractory material, it is then heated to get rid of the wax. once the wax is removed, the hot mold is cast. after cooling, the mold is removed through the use of vibration, higher pressure water blasting, impact, grit blasting, or chemical dissolution.
