Cuttlefish casting is a simple, traditional metal casting technique that takes advantage of the finely porous bone-like internal organ of a marine mollusc. The bone is composed of calcium carbonate and is soft enough to take permanent impressions by pressing or carving a shape into it’s surface. It is naturally resistant to the heat of molten metals like silver and gold, though the mold is destroyed by the process of casting.

Two pieces of cuttlebone are sanded flat on one side and bound together to form the mould. Once a design is created, a spout is carved at the top of the mould to allow the molten metal to be poured in. The natural layers in the bone impart a glorlious surface texture, similar to wood grain, creating a unique, one off pattern.
