Problems solved by technology

The obviousness of Jun porcelain flakes is related to the change of glaze color and the opacity of the glaze. Generally, glazes with high opacity are not as obvious as glazes with good transparency. However, the glass texture of existing ice cracked porcelain is too strong, while jade Insufficient texture

[0017] A preparation method of jade ice crack glaze porcelain, comprising the following steps:

[0018] (1) To make a green body of porcelain, apply a 0.8-2mm glaze on the surface of the green body to obtain a green body; wherein, the weight parts of each raw material in the glaze are as follows: 70-80 parts of anorthite, 15-20 parts of barium carbonate, 0-0.5 parts of zinc oxide, 0-0.5 parts of zirconia, 5-10 parts of wollastonite, 10-15 parts of boron oxide, 20-30 parts of neodymium oxide, 0-1 part of muscovite and Titanium quartz 5~10 parts;

[0019] (2) Pre-fire the green body prepared in step (1) in the furnace, and then uniformly heat it within 3~4.5h under the oxidizing atmosphere in the furnace until the temperature in the furnace rises to 850~900°C, and then Heating evenly within 0.8~1h until the temperature in the furnace rises to 950~980℃, and keep warm for 80~100min;

[0020] (3) Then, under the reducing atmosphere in the furnace, heat evenly within 3.5~5h until ...

Abstract

The invention discloses a preparation method of jade cracked ice glazed porcelain. The preparation method comprises the steps of preparing a biscuit of the porcelain, applying glaze of 0.8-2mm to the surface of the biscuit to make a green body, and firing the green body to prepare the porcelain. The following raw materials of the glaze are added according to parts by weight: 70-80 parts of anorthite, 15-20 parts of barium carbonate, 0-0.5 part of zinc oxide, 0-0.5 part of zirconium oxide, 5-10 parts of wollastonite, 10-15 parts of boron oxide, 20-30 parts of neodymium oxide, 0-1 part of white mica and 5-10 parts of titanium stones. In the preparation method, the expansion coefficient of a glaze layer is greater than the coefficient of thermal expansion of the biscuit and in the firing process, as the expansion coefficients are different, the tensile stress of the porcelain occurs, the glaze splits and cracks are formed; meanwhile, the glaze layer can generate silicate neodymium crystals, so that small crystal patterns show up in the ice cracks, and therefore, the ornamental value is improved.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a method for preparing jade ice-crack glazed porcelain. Background technique [0002] As one of the five famous porcelains in the Song Dynasty in my country, Jun porcelain began in the Tang Dynasty and flourished in the Song Dynasty. It is said that Jun porcelain transforms Weishen through the kiln, and there is one color in the kiln, and all kinds of colors out of the kiln; it is said that it is infinitely changing and has infinite artistic conception. The uniqueness of Jun porcelain includes its unique glaze color. Nowadays, many porcelain series pay attention to the texture of jade, and the texture of jade has become a very popular series in porcelain. [0003] Ice cracks, reflected in ceramics, are cracks in the shape of ice cracks, some of which are overlapping, and some of which are in the form of nets. The obviousness of Jun porcelain flakes is related to the change of ...
