Embodiment 1
[0019] A suet matt white glaze for pottery decorations, the technological formula is calculated by mass percentage, and consists of the following components: 15% feldspar powder, 17% calcium carbonate, 5% dolomite, 12% talc, carbonic acid 8% barium, 15% zirconium silicate, 15% zirconium white frit, 5% zinc oxide, 5% aluminum oxide, 3% kaolin.
[0020] The preparation method is as follows: weigh each component according to the formula, mix them fully and put them into a grinding tank, add 45-50% water equivalent to the weight of dry powder and grind for 10 hours, then sieve the ground glaze slurry to remove iron, and the concentration Adjust to the true specific gravity of 50-54 degrees, spray or soak or other decorative methods on the pottery, dry it and then enter the kiln for 8 hours of oxidation and firing at a temperature of 1200°C-1235°C, after natural cooling After leaving the cellar, suet matte white glaze is obtained.
