Method for forming hidden pattern effect on porcelain product

Abstract

The invention relates to a making method for forming concealed pattern effect on a ceramic product, using easily melting, bright, sub-matt or matt glaze, etc as ground coat on the surface of the ceramic product, then smearing transfer pattern of fluxing material prepared of water stop oil, or gum, or cellulose on the glaze or pasting under-glaze decal made of fluxing material, and then firing by kiln and forming the concealed pattern effect. And its key technique uses fusing temperature differences between various ground coats and fluxing material (the fusing temperature of the fluxing material is lower than those of the ground coats and the fluxing material does not emit color itself) to form the concealed pattern effect. And the invention can form a weakly comparative concealed pattern effect.

Description

technical field [0001] The invention relates to a production method for forming an invisible pattern effect on a ceramic product. Background technique [0002] In the current ceramic industry, commonly used methods such as underglaze pad printing, underglaze flower paper, overglaze decals, and spray color are often used to decorate the surface of ceramic products. The effects of the above decoration methods are generally relatively rigid, and The technical content is low, and the market competitiveness has been weakening year by year. Recently, technicians in some factories have been conducting experiments on pad printing on glaze, but most of the methods used are to add cellulose to the bottom glaze, and then use silk Scraping patterns on the net, adding cellulose to the glaze will cause the glaze slurry to sink to the bottom, form a plate, and shrink the glaze, which is not conducive to mass production.
