Soft Porcelain Clay : White
Bisque firing should be at 900 - 950°C. If it is not going to be glazed, it can be fired one time at 1200°C. If the bisque firing temperature is higher then 950°C, the glaze will not be vitrified with the body.
Glazed Firing Temperature : 1180 - 1200 °C. (Cone 5 - Cone 6)
Package Weight : 20 - 25 Kg
Pallet Dimension of 1 ton : 80*120*100 cm
