Embodiment 1

[0028] A tea powder glaze is prepared from the following raw materials: 40 parts of albite, 5 parts of iron oxide, 15 parts of silica, 2 parts of kaolin, 4 parts of talc, 2 parts of calcium carbonate and 0.5 part of tea powder. Wherein, the tea powder is the powder obtained by grinding the tea powder after it has been burnt off; the raw materials are all powder, and the average particle size of the powder is 0.5 μm.

[0029] The powdered tea glaze prepared in this example has a smooth, flat, delicate texture and no surface defects. The glaze is crystal clear, and the glaze color is yellow-green and moist.

Embodiment 2

[0031] A tea powder glaze is prepared from the following raw materials: 60 parts of albite, 10 parts of iron oxide, 30 parts of silica, 10 parts of kaolin, 15 parts of talc, 12 parts of calcium carbonate and 5 parts of tea powder. Wherein, the tea powder is the powder obtained by grinding the tea powder after being burnt; the raw materials are all powder, and the average particle size of the powder is 5 μm.

[0032] The powdered tea glaze prepared in this example has a smooth, flat, delicate texture and no surface defects. The glaze is crystal clear, and the glaze color is yellow-green and moist.

Embodiment 3

[0034] A tea powder glaze is prepared from the following raw materials: 53 parts of albite, 7 parts of iron oxide, 22 parts of silica, 5 parts of kaolin, 8 parts of talc, 7 parts of calcium carbonate and 2 parts of tea powder. Among them, the tea powder is the powder obtained by grinding the tea powder after it has been burnt off; the raw materials are all powder, and the average particle size of the powder is 2.8 μm.

[0035] The tea powder glaze prepared in this example has a smooth, flat, delicate texture and no surface defects. The glaze is crystal clear, and the glaze color is yellow-green and warm, which is very beautiful.

Abstract

The invention discloses tea-dust glaze and a preparation method thereof. The tea-dust glaze is prepared from albite, ferric oxide, silica, kaolin, talcum, calcium carbonate and tea dust powder. The preparation method comprises the steps that the raw materials are fully mixed, wet ball milling is conducted, and after screening is conducted, glaze slip is obtained; a green body is immersed into the glaze slip to be uniformly coated with the glaze slip, the glaze-coated green body is taken out and dried at a ventilation place, and a green body to be sintered is obtained; the green body to be sintered is placed in a furnace, heated to 900 DEG C, heated to 1,280 DEG through medium reduction sintering, heated to 1,300 DEG C through oxidation sintering, cooled to room temperature along with furnace cooling and then taken out to obtain a tea-dust glaze porcelain. Accordingly, the practicability of the tea-dust glaze is improved, and the glaze quality of the tea-dust glaze porcelain is greatly promoted.

Description

technical field [0001] The invention relates to the field of glaze making, in particular to a tea powder glaze and a preparation method thereof. Background technique [0002] Tea powder glaze was first fired in the Tang Dynasty, and continued to develop through the Song Dynasty. During the Yongzheng and Qianlong periods of the Qing Dynasty, Jingdezhen succeeded in imitating tea powder glaze again, and it became a rare and precious color glaze variety for the court supplies of the Qing Dynasty. From the analysis of the chemical composition and crystal structure of the tea powder glaze, the tea powder glaze is mainly composed of α-crystalline Fe 2 o 3 As a crystallization agent, it is a very important one in iron-based crystal glazes. Tea powder glaze is a high-temperature fired crystal glaze, which needs to be fired in a reducing atmosphere at a high temperature of 1200 ° C to 1300 ° C. The firing of tea powder glaze is more difficult. Due to the influence of firing tempe...
