Making method of white-ground colored crystal flower crystal glaze

Abstract

A making method of a white-ground colored crystal flower crystal glaze comprises the following steps: 1, crystal glaze material preparation: mixing albite, potash feldspar, quartz, mud, calcite, barium carbonate, zinc oxide and titanium dioxide, carrying out fine grinding, sieving by a 200 mesh sieve, and removing iron to obtain a crystal glaze material for later use; 2, engobe preparation: respectively selecting one of golden brown engobe prepared by fully and uniformly mixing praseodymium yellow with vanadium-zirconium yellow and finished mud, yellowish green engobe prepared by fully and uniformly mixing vanadium-zirconium blue with the praseodymium yellow and the finished mud and pinky engobe prepared by fully and uniformly mixing manganese red with the finished mud according to the color difference; 3, applying the engobe to white adobe, drying, applying the crystal glaze to the thickness of the obtained glaze layer of about 1mm; and 4, firing to a highest temperature, and cooling to room temperature. The controllable color change of crystal flowers is realized through different engobes, so the obtained white-ground colored crystal flower crystal glaze has the advantages of brilliant, multiple and hierarchic color, simple technology, wide firing temperature range, high yield and low cost.

Description

technical field [0001] The invention relates to the field of preparation of ceramic glazes, in particular to a preparation method of crystal flower crystal glaze with white background color. Background technique [0002] With the improvement of social aesthetics and appreciation of ceramic art, people pay more and more attention to the artistic value of ceramics. The aesthetic feeling brought to people by ceramic decorative art is unique and special. People's taste is constantly improving. For ceramics The grade requirements of products are also improving at the same time. Since the 1970s, the production technology and equipment of my country's ceramic industry have undergone comprehensive innovations. In the 21st century, when high-tech and new materials are developing rapidly, the entire ceramic industry must have a new look. Ceramics is a traditional product of our country. Whether it is daily-use ceramics or architectural ceramics, my country's output has already ranked...

Problems solved by technology

[0003] In the prior art, research on crystalline glazes has been quite mature. For example, the publication number CN101481261A published by the Patent Office in 2009 is called "a titanium, zinc, pyroxene crystalline glaze and its batching method". The glaze has the disadvantages of narrow firing temperature range and difficult to control the growth of crystal flowers. Titanium oxide and zinc oxide are introduced on the basis of pyroxene crystal glaze and mixed with the base material of pyroxene crystal glaze. The firing process of crystal-like glaze, the production process of this crystal glaze is the same as the firing process of conventional pyroxene crystal glaze, no special treatment is required, the crystal flower is easy to control and the operation process is simple, but the color of the crystal flower However, it is relatively single. Therefore, it is necessary to study the color of the crystal flower and work hard to realize the controllable change of the color of the crystal flower. This is of great significance to enhance the value of ceramic art.
