The plaster casing is heated over a long period at high temperatures until the wax inside vaporizes. What is left is a hollow mold into which molten silver or gold is shot using centrifugal force. When cooled, the mold is broken open to release the metal piece. A new wax replica must be made for every piece. Other designs are cut, hammered and formed entirely by hand.
Every piece is carefully hand polished.
No plating or lacquer is used.
