Lost-wax casting is the process by which a copy metal figure (frequently silver, gold, metal, or bronze) is cast from a unique model. Complicated works can be accomplished by this method.
The oldest known case of this process is a 6,000-year-old special necklace from Indus Valley Civilization. Different models of later periods are from Mesopotamia in the third millennium B.C.
The steps used in casting little bronze models are standardized, however, the procedure today differs from foundry to foundry.
