What is art clay in jewellery making?

Definition
Art clay is a brand of metal clay, a mouldable material made from microscopic particles of pure metal, most commonly fine silver, suspended in an organic binder mixed with water. While it is soft and workable like clay, you can shape, sculpt and texture it by hand or with simple tools, then fire it in a kiln or with a torch. As it heats, the binder burns away completely and the metal particles fuse together to leave a solid, pure metal object. Gold versions are also available.
Frequently asked questions
- What is the difference between art clay and polymer clay?
- Polymer clay is a plastic-based material that hardens in a low-temperature oven but stays plastic; it is not metal. Art clay contains actual metal particles and after firing becomes genuine solid metal, which can then be polished, soldered and hallmarked like any other precious metal piece.
- Can art clay pieces be hallmarked?
- Yes. Fired art clay silver is fine silver, 999 parts per thousand pure, and can be submitted for hallmarking in the same way as any other fine silver piece. Art clay gold produces a purer gold than most alloyed jewellery gold.
- Is art clay good for beginners?
- It is popular with beginners because it requires no specialist metalworking tools to shape, and mistakes can be repaired while the clay is still wet. Firing needs care, particularly with torch firing, but the learning curve is gentler than traditional metal fabrication.
