Problems solved by technology

However, it is difficult to choose the glaze material of celadon secret color glaze, and the firing temperature is not easy to control, so the finished product rate is low during kiln firing, so the firing process of "secret color glaze" has been lost since the Song Dynasty.

preparation example Construction

[0028] Correspondingly, the present invention also provides a preparation method of celadon secret color glaze, comprising the following steps: adding 28-35% of yellowstone xuan glaze soil, 5-10% of purple gold soil, 3-5% of feldspar powder, and 3-6% of talc powder %, 18-20% of limestone and 25-35% of ridge root glaze soil are mixed to obtain the glaze; the ball stone with a weight ratio of 1.3-1.5:1:0.8-0.9, the glaze and water are mixed and ground to obtain Glaze slurry; after the porcelain body is dried, it is biscuit fired at 840-880°C and cooled; the glaze slurry is adjusted to a water content of 38-45%, and the inner glaze is applied to the porcelain body by the glaze method, and then dipped in glaze The outer glaze is applied to the porcelain body; the glazed porcelain body is glazed and fired, and the glaze firing includes the evaporation stage, the reduction stage, the porcelain forming stage and the heat preservation stage in sequence, and the temperature of the porce...

Embodiment 1

[0042]The weight percentage composition of the glaze ingredients: Huangshixuan glazed soil 32%, purple gold soil 8%, feldspar powder 5%, talcum powder 5%, limestone 20%, linggen glazed soil 30%.

[0043] All kinds of glaze slurry are finely selected according to the formula requirements, mixed evenly, and then ball stone: glaze: water ratio of 1.3:1:0.9 is put into the grinding equipment to grind into glaze slurry.

[0044] After drying, it goes into the kiln for 6 hours of biscuit firing, then slowly fires with a warm fire until the temperature reaches 840°C and stops. After 15 hours of natural cooling, the biscuit comes out of the kiln, and the biscuit is then painted with powder and glazed. . The glazing of the biscuit is divided into two processes: inner and outer glazing. First, adjust the celadon secret color glaze slurry to a water content of 38%, and then apply the inner glaze of the bisque by the second glaze method, and the thickness of the glaze layer is controlled ...

[0048] The weight percentage composition of the glaze ingredients: 31% of Huangshixuan glazed soil, 6% of purple gold soil, 3% of feldspar powder, 6% of talc powder, 19% of limestone, and 35% of Linggen glazed soil.

[0049] All kinds of glaze slurry are finely selected according to the formula requirements, mixed evenly, and then ball stone: glaze: water ratio: 1.5:1:0.8, put into the grinding equipment and grind into glaze slurry.

[0050] A seven-inch octagonal bottle is molded from porcelain clay, and after drying, it goes into the kiln for 7 hours of biscuit firing, then slowly fires at 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 painted with powder and glazed. The glazing of the biscuit is divided into two processes: inner glaze and outer glaze. First, the glaze slurry is adjusted to a water content of 45%, and then the inner glaze of the biscuit is applied by the second glaze method,...

Abstract

The present invention provides a preparation method and a glaze material of a celadon secret color glaze. According to the present invention, Huangshixuan glaze soil, purple-gold soil, feldspar powder, talc powder, limestone and Ling'gen glaze soil are adopted as raw materials, air in the glaze can not float out of the glaze surface during the glaze firing process while a lot of small gas bubbles are formed, a certain number of undissolved quartz particles are remained in the glaze when the temperature of the porcelain forming stage is 1280-1310 DEG C, a large amount of anorthite crystals are formed, light entering the glaze layer produces the scattering due to the formed small gas bubbles, the formed quartz particles and the formed anorthite crystals so as to make the glaze layer have the transparent jade texture, and after the thermal expansion and contraction, the glaze layer cracks so as to form the stereoscopic vision effect of the smooth and rich jade; the prepared celadon secret color glaze has characteristics of green, mild and moist glaze color, good thermal stability and wide adaptability; and the preparation method is scientific and rational, and is easy to perform, and the obtained celadon secret color glaze product has characteristics of high yield and good product porcelain quality.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a preparation method of celadon secret color glaze and glaze material thereof. Background technique [0002] There are two completely different decoration methods for the glazed surface of Longquan celadon. First, the glaze surface has no grain, and the glaze color is mainly pink green and plum green, commonly known as "di kiln". "Ge Kiln" is one of the five famous kilns in Song Dynasty. Zhejiang Longquan Ge Kiln is one of the five famous kilns in the Song Dynasty in China. The celadon celadon vessels produced by it are treasured all over the world. The preparation process of Longquan Ge Kiln in Zhejiang Province is as follows: during the cooling process of celadon products after firing, the different shrinkage rates of glaze and body are used to crack the glaze into irregular textures, forming unique celadon products. In recent years, the production scale of Longquan celadon ...
