[0058] Step one, preparing glaze water main material

[0059] According to the mass fraction, the kaolin, potassium feldspar, vanadium oxide, and quartz are crushed, ball milled, and sieved to obtain a sieved material. Then, the sieved material is washed twice to obtain the glaze water main material.

[0072] 1. The flatness of the glaze surface: the products obtained in examples 1-3 are smoother and fuller than the product obtained in the control example;

[0073] 2. Stain resistance: when ink is dropped on the glaze surface, the ink on the surface of the products of examples 1-3 flows faster in the vertical direction than the ink on the surface of the product of the control example, and the ink mark is shallower;

[0074] 3. Thermal shock resistance: all four products do not crack when the temperature changes from 180℃ to 20℃ once.
