[0050] The invention makes full use of the excellent characteristics of quartz to solve the formulation of blank glaze and open flame firing process. First: Use domestic best-quality quartz (purity greater than 99.6%, particle size 200 mesh, well-crystallized vein quartz), with a whiteness of more than 90. Quartz becomes the skeleton of the green body at high temperature. Under reducing and oxidizing atmospheres After firing, the green body will appear beautiful tender white and elegant milky yellow. Second: According to the theoretical basis of the thermal expansion and phase change of quartz in the green body, during the firing process, the thermal expansion of quartz can partially offset the shrinkage of the green body, and form mullite together with alumina to prevent the green body softening deformation occurs. Third: Due to the high hardness of quartz, through the introduction o...
