  1. How to fire Art Clay Silver?
    There are 3 ways to fire Art Clay Silver:
1) Kiln, 2)Gas Torch, 3)Gas Stove.
Temperature is critical because over firing can cause the silver to melt.
Art Clay Silver matures at 870°C, a sintering temperature. This heat causes the silver particles to fuse together. This is only slightly lower than the melting temperature for fine silver (961.78°C). Fluctuations in firing temperature can result in reaching melting temperature.
     
  2. What are the limitations firing with the gas torch or gas stove?
    1) Should not fire glass, ceramics or other materials sensitive to rapid temperature changes.
2) Should not fire pieces larger than 25g, or piece larger than a 4cm in diameter.
     
  3. How to support a delicate object during firing?
    Using a soft ceramic fiber cloth/blanket.
     
  4. What is not suitable to fire?
    Never fire plastic, styrofoam, or similar materials. Aluminum foil must also be avoided. If you are uncertain, DON'T fire it.
