Embodiment 1
[0028] This embodiment proceeds according to the following steps:
[0029] 1) First prepare the following components according to the total weight percentage: quartz: 32.88%; feldspar: 38%; talc: 11%; clay: 2%; limestone: 6%; alumina: 3%; zirconium silicate: 7% ; Manganese oxide: 0.01%; Iron oxide: 0.1%; Chromium oxide: 0.01%, among which zirconium silicate is 3 micron grade;
[0030] 2) Then put the above solid raw material components into the drying room and bake respectively, wherein the moisture mass percentage content of quartz, clay and feldspar is controlled within 5%; the moisture mass percentage content of other solid raw material components is controlled within Within 1%;
[0031] 3) Add all the raw material components into the ball mill one by one according to the raw material ratio, and add water, the mass percentage content of water is required to be controlled at 32%, and the ball mill is 12 hours to form a glaze slurry;
[0032] 4) Pass the glaze slurr...
