The purpose of this research is to find the formula of the ice fissure glaze which has been used in ceramics since Song dynasty; to find the factors of influencing the size and the layers of the cracklings of which characterize the ice fissure glaze. And it aimed at the discussion of different manifestation of the ice cracklings on the surface of various bisque wares.
The procedure of the research is: First we probed into the literature to become familiar with ice crackle glaze on green ceramics by predecessors, and understand the theorem of cracklings. Then we designed the experiments according to the theory and found the factors that influenced the cracklings. We have several conclusions as below after the experiments.
To sum up the conclusions:
1) According to the result of the experiments, there’re two formulas for the most stable and the best glaze. The formulas are as below: 1. Nepheline syenite 100g, CaCO3 8g 2.Nepheline syenite 100g, 4Ca3(PO4)2．2CaCO3 6g
2) The consistency and the thickness of the glaze on the ceramic influence the outcome of crackling after firing. Applying thick formula 1 Nepheline syenite 100g, CaCO3 8g can make ice crackle glaze. Applying thin formula 2 Nepheline syenite 100g, 4Ca3(PO4)2．2CaCO3 6g can make ice crackle glaze.
3) Adding different colorants to the basic formula for ice crackle glaze, influences the luster and the outcome of crackling after firing.
4) It produced layers of ice crackles on pottery and only cracks on porcelain.
5) The crackles produce variation due to the ingredient of K2O or Na2O when we use different feldspars in the glaze formula.
6) It produces different outcomes when we apply the glaze for ice crackle on bisque ware of different shapes. Applying on flat bisque ware is more easily to succeed than applying on curve bisque ware.
