Problems solved by technology

Tea powder glaze belongs to the traditional iron-based crystalline glaze, which has relatively fixed basic component requirements and extremely high kiln firing curve system. Due to the matching requirements of the blank glaze, etc., this makes the glaze effect of most tea powder glazes prepared at present unsatisfactory; and most of the raw materials for preparing tea powder glazes on the market are chemical raw materials, which makes the cost of tea powder glazes prepared high, not environmentally friendly

Abstract

The invention provides a tea dust glaze prepared from natural mineral soil and a firing method of the tea dust glaze. The tea dust glaze is prepared from the following raw material components in percentage by mass: 73 to 77% of loess and 23 to 27% of screw soil, wherein the loess is loess in five-color soil in Jianshui county of Yunnan Province, and comprises the following main components in percentage by weight: 73-76% of silicon dioxide, 12-15% of aluminum oxide and 4.5-5.5% of ferric oxide; the screw soil is mineral soil in Jianshui county, and comprises the following main components in percentage by weight: 48 to 51% of calcium oxide, 5.5 to 6.5% of silicon dioxide, 2.4 to 2.8% of ferric oxide and 4 to 4.5% of aluminum oxide. The tea dust glaze is completely prepared from natural mineral soil; and after firing of the tea dust glaze, the color of the tea dust glaze is stable, glaze surface effect is good, and the matching performance of a green body and the glaze is good.

Description

technical field [0001] The invention relates to the technical field of glaze preparation, in particular to a method for preparing and firing tea powder glaze from natural products in Jianshui County, Yunnan Province, my country. Background technique [0002] Tea powder glaze, also referred to as tea powder glaze, is made of iron oxide as the coloring agent and fired in a high-temperature reducing flame between 1200°C and 1300°C. The glaze surface is devitrified, and the glaze color is yellow and green mixed with tea fine powder. The green one is called tea, and the yellow one is called powder. It is simple and beautiful, and intriguing. Tea powder glaze belongs to the traditional iron-based crystalline glaze, which has relatively fixed basic component requirements and extremely high kiln firing curve system. Due to the matching requirements of the blank glaze, etc., this makes the glaze effect of most tea powder glazes prepared at present unsatisfactory; and most of the raw...
