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 produce 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.
[0004] Jun porcelain is expensive in the kiln. Although the calcium matte glaze has a strong adaptability to colored glazes, the glaze surface is relatively rough.
Although magnesium matte glaze can obtain a smooth and delicate glaze surface, it has poor adaptability to colored glazes

Embodiment 1

[0018] A magnesium-based blue matte glaze, which is composed of the following raw materials in parts by weight: feldspar 30-36, quartz 7-9, talc 22-28, dolomite 9-11, kaolin 5-7, boron frit 13- 15. Cobalt oxide 2.5-3.5, manganese oxide 0.8-1.2. Among them, feldspar, talc, dolomite and kaolin are taken from Yuzhou. The boron frit is purchased from domestic manufacturers, preferably with boron oxide content greater than 5%, calcium oxide greater than 7% and magnesium oxide greater than 1.5%; the main chemical composition content of the boron frit used in the present invention: silicon oxide 51.6%, aluminum oxide 11.8%, calcium oxide 7.8%, magnesium oxide 2.1%, boron oxide 8.7%, zinc oxide 4.6%, barium oxide 2.5%, potassium oxide 4.6%, sodium oxide 3%.

[0019] The preparation method of magnesium-based blue matte glaze as described above comprises the following steps:

[0020] (1) Mix the raw materials; ball mill to obtain the glaze slurry; pass the glaze slurry through a sieve...

Embodiment 2

[0026] A magnesium-based blue matte glaze is composed of the following raw materials in parts by weight: 33 parts by weight of feldspar, 8 parts of quartz, 25 parts of talc, 10 parts of dolomite, 6 parts of kaolin, 14 parts of boron frit, 3 parts of cobalt oxide and 1 part of manganese oxide.

[0027] The preparation method of magnesium-based blue matte glaze as described above 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: Firstly, 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 1300°C in 2.5 hours; kept for 40 minutes, and then cooled in 7 hours to room temperature.

[0031] The glaze color of the product prepared in this exa...

Abstract

A magnesium-based blue matt glaze is composed of the following raw materials (by weight): 30-36 parts of feldspar, 7-9 parts of quartz, 22-28 parts of talc, 9-11 parts of dolomite, 5-7 parts of kaolin, 13-15 parts of boron frit, 2.5-3.5 parts of cobalt oxide, and 0.8-1.2 parts of manganese oxide. According to the magnesium-based blue matt glaze provided by the invention, cobalt oxide with strong coloring ability is used as a coloring agent, and high-boron frit is used and a certain amount of manganese oxide is added to promote color development. Thereby, the coloring power of the magnesium-based matt glaze is improved, stable blue glazing color is formed by furnace transmutation, and a good glaze is obtained.

Description

technical field [0001] The invention belongs to the technical field of Jun porcelain production, and in particular relates to a magnesium-based blue matte 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. 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. [0003] Matte glaze refers to the art glaze with weak reflective ability on the glaze surface, no glassy luster on the surface but soft silky, velvet, waxy, jade-like luster. The matte glaze can be prepared by the following three methods: 1. Reduce the glaze firing temperature or increase the c...
