Lost-wax casting is the process by metal (such as brass ,bronze,silver, gold). Intricate works can be achieved by this method. In industrial, today's process is called investment casting. An old practice, the process today is different from foundry to foundry, but the steps which are usually used in casting small art forms in a modern bronze foundry are normally very standardized.

The beginning of the lost wax casting process in antiquity, but it has been used for centuries to create products in metal that could not be produced any other way, because of the complexity of their shape. It enables anything that can be modelled use wax,and is still used today for industrial parts, jewelry.
