Description: This video shows the second stage of the production of a cast gold crown for a damaged tooth. The wax template of the tooth is sprued using wax wire, then invested in a refractory investment material. The video shows the mould being heated to both expand it and prevent against thermal shock. A centrifugal casting process is shown, using an electrical furnace for melting the gold.
