Problems solved by technology

When the traditional powder green glaze is used in the manufacturing process of ceramic products, there are problems that the process requirements are too harsh. For example, "bubbling" phenomenon is easy to occur when over-fired, and "smoking" phenomenon is easy to occur if the atmosphere control is not accurate, resulting in the qualified rate of ceramic products. Low, hard to ejaculate

Embodiment 1

[0022] The weight percent composition of the glaze formula: glaze fruit 65, feldspar 16, quartz 8, talc 6, fly ash 5. Add 0.04% chromium oxide.

[0023] During production:

[0024] All kinds of glaze slurry are finely selected according to the formula requirements, mixed evenly, and then the ratio of ball stone: glaze material and water is 1.5:1:0.8, and then put into the grinding equipment to grind into glaze slurry.

[0025] A jade pot is molded from porcelain clay, and after spring drying, it goes into the kiln for 6 hours of unglazed firing, and then slowly fires at a temperature of 840°C to stop. After 15 hours of natural cooling, the green body comes out of the kiln, and the green body is then painted with powder and glazed. Glazing is divided into two processes: inner glaze and outer glaze. First, the glaze slurry is adjusted to a water content of 38%, and the inner glaze of the biscuit is first glazed twice with the method of swaying the glaze. The thickness of the gl...

Embodiment 2

[0029] Embodiments Glaze batching weight percentage composition: glaze fruit 73, feldspar 11, quartz 6, talc 5, fly ash 5. Add 0.05% chromium oxide.

[0030] During production:

[0031] After careful selection of various glazes, mix the ingredients according to the formula evenly, and then use the ratio of ball stone: glaze: water: 1.5:1:0.8, put it into the grinding equipment and grind it into glaze slurry.

[0032] After forming a garlic bottle with porcelain clay, it goes into the kiln for 7 hours of unglazed firing, then slowly burns with a warm fire until the temperature is 880°C and stops. After 20 hours of natural cooling, the biscuit comes out of the kiln, and then it is painted with powder and glazed. There are two processes of applying inner and outer glazes. First, the glaze slurry is adjusted to a water content of 45%, and then the inner glaze of the biscuit is applied twice using the glaze method, and the thickness of the glaze layer is controlled at 2.3mm; the i...

Abstract

The invention relates to a powder green glaze material, which is a slurry obtained by mixing the powder green glaze raw materials according to the formula, and then through ball milling, sieving, and iron removal processes, including powder after dehydration and drying. A proper amount of talc, chromium oxide and other raw materials are introduced into the formula, which solves the problems of over-burning, foaming and "smoking" in the process of high-temperature melting of traditional blue-glazed ceramics. The glaze is green, smooth, delicate, gorgeous and pure in color. The quality is as clean as jade; the invention also discloses a method of using the powder green glaze to manufacture ceramic products at the same time. The powder green glaze ceramic products produced by the method have high yield, good density and strong acid and alkali corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a powder blue glaze in high-temperature color glaze and a production method of the product thereof. Background technique [0002] The craft decoration of "winning with glaze" has always been popular, and it is classified according to the appearance characteristics after firing: cracked glaze, floral glaze, monochrome glaze and so on. Monochrome glaze has always been loved by literati for its simplicity and elegance. Among them, the pink blue glaze is more like ice and jade, green and smooth, delicate and gorgeous, giving people endless reserves for viewing. Any modern glaze, traced back to its source, is the lime glaze of the early pink celadon glaze, which was deduced through lime alkali glaze. When traditional powder green glaze is used in the manufacturing process of ceramic products, there are problems that the process requirements are too harsh. For ...
