Description

Gradient color glaze ceramic and preparation method thereof
Technical Field
The invention relates to the field of ceramics, in particular to a gradual color glaze ceramic and a preparation method thereof.
Background
The colored glaze is characterized in that certain oxidized metal is added into the glaze, and the glaze can show certain inherent color after being roasted, so the colored glaze is called as the colored glaze. Different metal oxides are added into the glaze material as coloring agents, and the glaze material can present glaze with different colors and become colored glaze when being fired at a certain temperature and air temperature. The traditional colored glaze has the following components: green glaze taking iron as a coloring agent; red glaze with copper as coloring agent; blue glaze with cobalt as coloring agent. Historically, many times have been outstanding representatives of colored glazes, such as the blue and jun reds of the Song Dynasty, the celadon of the Ming Dynasty, the Lanzhou red, the Wujin glaze, the tea dust glaze of the Qing Dynasty, and the like. The difference between the colored glaze and the common colored glaze lies in the special firing process and formula of the colored glaze. The glaze surface of the colored glaze must be calcined at a high temperature of more than 1250 ℃ to show the unique charm of the colored glaze like flowing oil, rainbow-like color and cloud-like pattern. The colored glaze is colorful and various. The traditional colorful glaze process comprises the following steps: through going up multilayer frit in proper order, through the different frit that distributes in different positions on the body, form the present of multiple color, although traditional colorful glaze technology can present multiple color, the presentation mode is comparatively single, can't present the colour blending effect, in view of this, the present case produces from this.
