Gravity casting covers a series of casting mold materials like cuttlebone, charcoal, sand, stone, water and other easy receptacles that can shape the metal in a direct mold using gravity as you pour the melted metal. These techniques have been used since ancient times as a molds for casting. Popular mold materials often are items found around the artist in there environment. Nowadays most reusable molds are made of a silicone or rubber. But, cuttlebone, sand, stone and charcoal are continued to be used as a mold materials, ingot mold and for creating unique designs in small studios. We will explore ways to use these direct carvable molds specifically to create unique stone settings. Gravity casting is continued to be used because of the ease of the process, availability, and convenience to create metal designs. These mold materials are generally easy to shape resulting in unique opportunities to create amazing stone settings.

Materials for gravity casting
Potential mold materials
- Cuttlebones - these can be purchased from bird suppliers and some jewelry suppliers. I get my medium to large bones from Great Companions on line. Most cuttlebones are only able to be used once.
- Soft charcoal block - There are differs kinds of charcoal blocks. Be sure to use soft charcoals solder blocks for casting. These can generally be used a few times if you are careful. The mold will deteriorate a bit with each use.
