Embodiment 1
[0027] A tea powder glaze prepared with natural mineral soil, the raw material components are 75% of loess and 25% of screw soil in terms of mass percentage;
[0028] The loess is the loess in the five-color soil in Jianshui County, Yunnan Province, my country, and its main components are 73-76wt% of silicon dioxide, 12-15wt% of aluminum oxide, 4.5-5.5wt% of iron oxide, For other oxides and impurities, the pH value is 4.2 to 4.8, and it is weakly acidic;
[0029] The screw soil is also called Mengsi soil, which is a kind of mineral soil in Jianshui County. , Al2O3 4-4.5wt%, the rest are other oxides and impurities, the pH value is 8.5-9.5, and it is weakly alkaline.
[0030] The firing method of tea powder glaze is as follows:
[0031] (1) Weigh 75% of loess and 25% of screw soil by mass ratio, crush and mix the loess and screw soil evenly into mixed soil ore, add the mixed soil ore into the ball mill tank, add water, and ball mill for 72 hours, namely The thick yellow glaze...
