  • Description

Heat resistant Cubic zirconia Amethyst 7x14mm Marquise.

Heat resistant cubic zirconia,

Cubic Zirconia, jeweller's quality. Marquis sharpened and safe to bake directly in the clay.

This stone is a lab-made Cubic zirconia and is heat resistant.

This stone can be set in silver clay and fired in an kiln, with a microtorche or on the gas stove. The stones have been tested for 30 minutes at 850°C.

Set in copper or bronze clay, it can be fired for 4 hours in activated carbon at 850°.

  • Preferably place large stones in a cold kiln and allow them to cool down in the kiln after firing. Temperature fluctuations can cause the stone to crack.
  • Do not cool in water, the stone will crack due to the shock.
  • A hole under the stone ensures that the shrinkage of the clay is better distributed during firing. Otherwise it is possible that the stone will crack or become dull during firing.
  • A hole under the stone also allows light to enter so that the stone is much more lively.
  • Make sure that the clay encloses the stone properly, otherwise it can be pushed out during firing.
  • Clean the stone well before firing, it is not possible to remove the silver after firing. Use a wooden skewer for this.
