Burning process and outstanding features
This clay formula has the special property of being translucent and will become completely vitrified at a temperature of Cone 10 (1300°C).
- Bisque Firing: The optimum temperature is 1000°C (Cone 05), with a shrinkage rate of approximately 6.7% and a relatively high water absorption of 15.5%.
- Glaze Firing: The recommended temperature is 1300°C (Cone 10). In this glaze firing, the clay shrinks up to 12.9% and has a very low water absorption rate of only 0.22%, indicating a strong glassy consistency.
Color after burning
The color of the piece after firing depends on the atmosphere in the kiln.
- If burned in an oxidation atmosphere, the workpiece will be white and clean.
- If burned in a reduction atmosphere, the piece will produce a beautiful blue-gray color.
