Jewelry wax is a technical wax designed to burn out completely inside a mold, leaving no residue. It is sold in blocks, tubes, sheets and wires, of varying hardness. Models that will be cast in metal are carved with it.

- **Soft wax:** for modeling with a spatula and the hand.
- **Injection wax:** melted to inject into rubber molds.
- **Sheets and wires:** for building bases, bands and details.
- **Colors:** indicate hardness or use.
