[0025] 3. Glaze preparation and glazing

[0026] First, burn the raw material of the bright red glaze that has been weighed according to the requirements to make a full frit, and then ball mill it with ball stones and water in a ratio of 1:1.5:0.45. When it is 0.01-0.04% (finer sieve is also acceptable, and the sieve residue is more), adjust the specific gravity of glaze slurry to 1.85-1.95g / m 3 , and then apply the bright red glaze on the biscuit body of the bone china by spraying the glaze, the thickness of the glaze layer is 0.6-1.0mm, and dry in the air.

[0027] Then, the transparent glaze raw materials weighed according to the requirements are fired into a full frit, and then ball milled with ball stones and water in a ratio of 1:1.5:0.45. When the fineness of the glaze slurry reaches 0.01 ~0.04%, adjust the specific gravity of glaze slurry to 1.85~1.95g / m 3 , and then use the method of spraying glaze to apply transparent glaze on the bisque body that has been applied ...

Embodiment

[0029] Embodiment: According to above-mentioned implementation mode to bone china big red glaze, pumpkin bottle (high 310mm), 455ml landscape cup and 100 pieces of European-style dish are made respectively, and its main performance and index are as follows:

[0030] 1. The prepared bone china red glaze is gorgeous dark glaze, the glaze surface is evenly moisturized, the color is bright, and the color lasts for a long time.

[0031] 2. The thermal stability of the glaze surface is good, and the glaze layer does not crack after one heat exchange at 180-20°C, which meets the national standard.

[0032] 3. The dissolution amount of lead and cadmium is less than 0.226mg / ml and 0.5mg / ml respectively, meeting the most stringent international standards and safe to use.

[0033] 4. The chemical composition (parts by mass) of the bright red glaze is: SiO 2 53.26~59.63, Al 2 o 3 For, 1.23~15.96, Fe 2 o 3 0.12~0.53, CaO is 4.32~10.21, MgO is 0.56~4.65, K 2 O is 1.45-4.98, Na 2 O is...

Abstract

The invention discloses a preparation method of bright red glaze bone china, wherein the bone china is prepared by the bright red glaze, the bone china comprises a bright red pigment glaze layer and a transparent glaze layer, the bright red pigment glaze layer is prepared by the following steps of: using 10-20 parts of BF242 clinker, 20-32 parts of DF-02 clinker, 6-14 parts of Suzhou soil and 42-56 parts of bright red coating pigment as raw materials, burning the raw materials to entire-clinker, adding water therein and ball milling the same, adjusting the specific gravity of the glaze slip to 1.85-1.95 g/m3 if the glaze slip fineness reaches to such a condition that the screen residue of a sieve with 325 meshes is 0.01-0.04% after the deironization procedure, coating the bright red pigment glaze on a bone china bisque body by a glaze spraying method, wherein the thickness of the glaze layer is 0.6-1.0 mm, and drying; coating the transparent glaze on the dry bisque body with bright red pigment glaze, and drying the bisque body; and sintering the bone china under an oxidizing flame atmosphere, wherein the highest sintering temperature is 1090+/-1 DEG C. The prepared product has the advantages of moist and uniform glaze surface, brilliant and fadeless color, good thermal stability and non harmful lead and cadmium dissolution.

Description

technical field [0001] The invention relates to a preparation method of red-glazed bone china. technical background [0002] Bone China originated in the United Kingdom and is a world-recognized high-grade porcelain with a history of more than 300 years. It is made by mixing animal bone ashes into ceramic raw materials and firing at high temperature to become a porcelain with high whiteness, high transparency and fine quality. Porcelain and bone china decorated with colored glaze are more popular in the market. Colored glaze is a decorative glaze in which some metal oxides are added to transparent glaze raw materials as colorants and fired at high temperature to present various colors on the glaze surface. Among them, red glazed porcelain represents auspiciousness and wealth, including Junhong, alum red, copper red, Blush, coral red, etc. Related reports on bone china glaze and red glaze are as follows: [0003] CN101580407 discloses a method for preparing underglaze bone...
