The cuttlefish bone (or cuttlebone) has been used since ancient times as a mold for casting. It was popular as a mold material up to the time of the invention of vulcanized rubber, which took its place as a primary mold in the jewelry industry. Nowadays, most reusable molds are made of silicone or rubber. Cuttlebone is still continued to be used as a mold material, ingot mold, and for creating unique designs. We will discuss other types of gravity casting using other materials like soft charcoal blocks, tufa, and sand.
