Method for preparing spray decoration crystal glazed pottery porcelain

Abstract

The invention discloses a method for preparing spray decoration crystal glazed pottery porcelain. The method comprises the following steps: (1) preparing a soaking glaze, namely mixing raw materials of a soaking glaze, performing wet-method ball milling, deironing, screening, and blending so as to obtain the soaking glaze for later use; (2) preparing a spray decoration material, namely mixing raw materials of a spray decoration material, performing wet-method ball milling, deironing, screening, and blending so as to obtain the spray decoration material for later use; (3) preparing a porcelain blank; (4) performing biscuiting; (5) performing glaze soaking, namely soaking the porcelain blank into the glaze; (6) performing spray decoration, namely spraying the spray decoration material to a product after glaze soaking and natural drying, and naturally drying; (7) firing, namely firing the product after spray decoration. The method has the advantages that the spray decoration crystal glazed pottery porcelain has crystal glaze points which protrude and are uniformly distributed on the surface of a glaze layer, is smooth in glaze point surface, good in crystal effect, good in three-dimensional feeling of a decoration glaze layer, tidy in appearance, easy to clean and relatively good in sense of beauty.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a preparation method of spray-painted crystal glaze ceramics. Background technique [0002] Both daily-use ceramics and display art ceramics belong to living ceramics. These ceramics are basically decorated with ceramic glazes, so that the ceramics are beautiful, hygienic and easy to clean. [0003] The glazes used in ceramics include transparent glazes, opacified glazes, and colored glazes. Among the special glaze varieties, there is a type called crystal glaze, because the glaze is used on the surface of ceramic products. After firing, the glaze layer is transformed into crystals by kiln transformation, and these crystal patterns produce decorative effects. Conventional crystalline glaze forms a flat and smooth layer on the surface of ceramics, and the three-dimensional effect is poor. The patterns displayed are usually irregular, and sometimes the distribution of patterns i...

Problems solved by technology

Conventional crystalline glaze forms a flat and smooth layer on the surface of ceramics, and the three-dimensional effect is poor. The patterns displayed are usually irregular, and sometimes the distribution of patterns is difficult to achieve uniformity; The pattern can be evenly distributed, resulting in a higher aesthetic feeling of the crystalline glaze layer, which sets a new research topic for the ceramic industry in terms of technology and process innovation
