|Casting: Casting is the process which results in the final sculpture. The sculptor chooses a material to be cast into the final piece. Materials often used include plasters, metals, resins and fiberglass. The material is poured, brushed or rotated into the hollow area of the molds and allowed to set, or harden. (In the case of metals, additional steps must be taken during the casting process.) After the casting material has set, the two molds are removed from the cast piece.
