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 lavender grey glaze. After raw materials of the lavender grey glaze are proportioned according to the prescription, the ball milling, sieving and de-ironing procedures are carried out to obtain slurry. The raw material comprises dehydrated and dried powder. By introducing talc, chromic oxide and the like into the raw materials, the invention solves the problems of easy burnt blistering and smoke absorption in the high-temperature roasting process of the traditional lavender grey glaze ceramic. The glaze surface is green, smooth, fine and beautiful, the color is pure, and the ceramic is clean and similar to jade. The invention also discloses a method for manufacturing the ceramic products by using lavender grey glaze, and the lavender grey glaze ceramic finished product manufactured by the method has the advantages of high yield rate, good density and strong acid and alkaline corrosion resistance property.

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 ...
