Lost-wax casting (also called “investment casting“, “precision casting”, or cire perdue in French) is the process by which a duplicate metal sculpture  (often silvergoldbrass or bronze) is cast from an original sculpture. Dependent on the sculptor’s skills, intricate works can be achieved by this method.
