Problems solved by technology

Most of the existing ceramic blanks are obtained by processing clay, and because the clay contains a large amount of alkali metal compounds and sulfates, it will not only change the color of the pigment, but also cause oxidative peeling and difficult coloring.

Abstract

The invention relates to the field of a ceramic firing industry and discloses a colored ceramic body capable of enhancing coloring performance. According to the colored ceramic body, black soil is used as a main raw material and fly ash is doped according to a pre-set ratio; the water consumption for processing a ceramic body and the size stability after sintering and ceramization can be remarkably reduced; the problem that the ceramic body absorbs moisture to be expanded and is easy to crack is solved; after a blank prepared by commonly grinding a mixture and residual materials is subjected to ceramization at pre-set temperature, the hardness is good and the porosity is low; the surface of the body can become smooth; when pigment is used for painting on the body, the adsorbability to thepigment is strong, an original color of the pigment is presented, the coloring rate is remarkably enhanced and the lasting degree is high; the invention provides an effective way for improving the coloring performance of the colored-pottery ceramic body; the preparation raw materials are easy to obtain, a production process is simple and the efficiency is high; the effective way has the advantagesof convenience for operation, safety and reliability and the ceramic body has the advantages of water resistance, corrosion resistance, high temperature resistance and the like, and also has the advantages of long service life and the like; the colored ceramic body has important significance of popularizing and applying colored pottery culture and is a technical scheme which is extremely worthy of being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of ceramic firing industry, and in particular relates to a colored ceramic blank capable of enhancing the coloring performance. Background technique [0002] Painted pottery refers to the use of natural mineral pigments to paint smooth orange-red pottery, using ochre and manganese oxide as coloring elements, and then fired in a kiln. On the orange-red carcass, there are beautiful patterns of ocher red, black, white, and various colors, forming a pottery with a high degree of unity between the pattern and the shape of the utensils, and achieving the effect of decoration and beautification. [0003] Painted pottery is exquisitely made, mainly clay pottery, with fine texture, so it is not only a practical vessel, but also has high artistic value. Since the color is painted before firing, after firing together with the pottery, the color is closely combined with the pottery body and is not easy to fall off. Th...
