Abstract

The invention discloses a production method of ceramic with engobe decoration. The production method comprises the following steps: (1) preparing a blank; (2) mixing 65-70 parts by mass of clay, 15-20 parts by mass of low-temperature frit, 2-5 parts by mass of sinking beads, 5-10 parts by mass of feldspar, 2-5 parts by mass of aluminum hydroxide micro powder and 1-2 parts by mass of an expanding agent to obtain an engobe raw material, grinding and sieving the engobe raw material, and grinding the engobe raw material into slurry according to the ratio of the material to the balls to water being (1-1.1): (2-2.1): (1-1.1); (3) covering the slurry obtained in the step (2) on the blank prepared in the step (1), naturally air-drying, and carving a preset pattern on the blank coated with engobe; and (4) firing: firing the blank decorated in the step (3) in an oxidizing atmosphere at the firing temperature of 1240-1300 DEG C for 12-14 hours to obtain a product. According to the production method, the engobe is more uniformly covered on the blank, and the problems of discontinuity and spacing lines between the engobe and the blank in the firing process are solved.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a production method of ceramics decorated with cosmetic clay. Background technique [0002] Ceramic decoration art is divided into over-glaze, under-glaze, and in-glaze forms; according to techniques, it is divided into drawing, engraving, and heap carving; according to glaze color, it is divided into monochrome glaze, composite glaze, and floral glaze; Light glaze, opaque glaze; according to the artistic state of the glaze, it can be divided into split glaze, crystal glaze, metallic luster glaze, etc. [0003] There are famous kiln mouths in history, Cizhou Kiln and Jizhou Kiln. Their decoration techniques are: apply a layer of black glaze on the gray and white body, and then draw dragon patterns, flowers, animals and other patterns on the glaze surface. [0004] Hubei Hanchuan Makou pottery is exported to many countries. It is tied to the clay-made pottery. First, a layer of ...
