Problems solved by technology

Because Jun porcelain mainly obtains kiln-changed color by high-temperature kiln transformation, method 1 is not suitable for the production of Jun porcelain matte glaze; method 3 can be used to obtain matte glaze by controlling the ratio of silicon to aluminum in the glaze and adding an appropriate amount of matting agent Generally, there are calcium matte glaze, magnesium matte glaze, zinc matte glaze and barium matte glaze. Although barium matte glaze and zinc matte glaze have better effects, the cost of these two raw materials is relatively high; calcium matte glaze The obtained glaze is rough, but it has strong adaptability to colored glaze; although magnesium matt glaze can obtain smooth and fine glaze, it has poor adaptability to colored glaze

Embodiment 1

[0018] A red matt glaze, which is composed of the following raw materials in parts by weight: feldspar 32-38, quartz 11-13, calcite 9-11, talc 11-13, wollastonite 7-9, copper ore 10-14, Kaolin 6-8, zinc oxide 1.5-2.5, aluminum oxide 1.5-2.5.

[0019] The preparation method of the above-mentioned red matte glaze comprises the following steps:

[0020] (1) Mix the raw materials; ball mill to obtain the glaze slurry; pass the glaze slurry through a sieve of more than 200 mesh;

[0021] (2) Glaze is applied to the carcass after bisque firing; the thickness of the glaze is 0.6-0.8mm;

[0022] (3) Firing: First, the temperature of the glazed carcass is raised to 1000-1100°C evenly in 3.5-4.5h in an oxidizing atmosphere; then the temperature is evenly raised to 1300-1320°C in 2-3h in a reducing atmosphere ; Keep warm for 25-60 minutes, then keep warm and cool, and cool to room temperature for more than 6 hours.

[0023] The feldspar, quartz, calcite, talc, wollastonite, copper ore...

Embodiment 2

[0026] A red matte glaze is composed of the following raw materials in parts by weight: 35 feldspar, 12 quartz, 10 calcite, 12 talc, 8 wollastonite, 12 copper ore, 7 kaolin, 2 zinc oxide and 2 aluminum oxide.

[0027] The preparation method of the above-mentioned red matte glaze comprises the following steps:

[0028] (1) Mix the raw materials; ball mill to obtain the glaze slurry; pass the glaze slurry through a sieve of more than 200 mesh;

[0029] (2) Glaze is applied to the carcass after bisque firing; the thickness of the glaze is 0.6-0.8mm;

[0030] (3) Firing: first, the temperature of the glazed carcass is uniformly raised to 1050°C in 4 hours in an oxidizing atmosphere; then in a reducing atmosphere, the temperature is evenly raised to 1310°C in 2.5 hours; kept for 40 minutes, and then cooled in 7 hours to room temperature.

[0031] The glaze prepared in this example is smooth and fine, with a glossiness of 4.1%. The finished product rate can reach 92% by gas burni...

Abstract

Red matt glaze is prepared from, by weight, 32-38 parts of feldspar, 11-13 parts of quartz, 9-11 parts of calcite, 11-13 parts of talc, 7-9 parts of wollastonite, 10-14 parts of copper ore, 6-8 partsof kaolin, 1.5-2.5 parts of zinc oxide and 1.5-2.5 parts of aluminium oxide. According to the red matt glaze, through the raw materials frequently used for producing jun porcelain, the consumption ofsilicon and aluminum material feldspar, silicon material quartz, calcium material calcite, wollastonite and magnesium material talc in the raw materials is adjusted; in cooperation with copper ore, kaolin and a proper amount of zinc oxide and aluminium oxide, the glaze silicon-aluminum ratio is adjusted, the content of magnesium and calcium in the glaze is increased, and finally the red matt glazewhich is smooth and fine in glaze surface is obtained; the yield is high and is 90% or above, and the red matt glaze is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of Jun porcelain production, and in particular relates to a Jun porcelain red matt glaze and a preparation method thereof. Background technique [0002] Jun porcelain began in the Tang Dynasty and flourished in the Song Dynasty. It is one of the five famous porcelains in ancient my country. Among the many glaze colors of Jun porcelain, red has always been the most expensive, and red glaze occupies an important position in Jun porcelain. [0003] The glaze layer of Jun porcelain is relatively thick, with a strong sense of layering and three-dimensionality. The appearance has a jade-like texture and luster. For good Jun porcelain. Because Jun porcelain has the distinctive feature of opalescent glaze, there are few reports of Jun porcelain matt glaze in the prior art. [0004] Matte glaze refers to the art glaze with weak reflective ability on the glaze surface, no glassy luster on the surface but soft silky...
