Abstract:Zinc silicate crystalline glaze was prepared with alaskite as principal raw material, ZnO as nucleation agent, and MnO2,CuO or Fe2O3 as coloring agent. The problem of the disorderly growth of crystals was solved by localizing crystal nuclei. An optimal recipe was designed after considering the influence of the content of ZnO, talcum and coloring agents on glazing effect and a fancy crystalline glaze was prepared. It was found that holding time was an important factor affecting the size of the crystallization. Analyzing the phase of the glaze layer by XRD proved that the prepared sample was zinc silicate crystalline glaze.
