Ceramic pigment and glaze, is the construction of sanitary ceramics products decorative coat. It is the matrix of ceramic products and integrated closely with glaze, plays a decorative landscaping construction the role of sanitary ceramics products, enabling products to form a colorful world of ceramics. Now the development of ceramic industry has entered a new era of color glaze, building sanitary ceramics products decorative increasingly inclined to direct the use of a variety of color glaze in order to build a range of new product lines to meet the diverse needs of domestic and foreign markets. Therefore, the master glaze ceramic pigment good use of technology to improve product quality and rich variety of enterprises and the types of products of great significance.
　　Pigment technology includes the use of ceramic glaze pigment products used in all aspects of the process, in which the main pigment of the use of process conditions; pigment color problems; pigment particle size selection; pigment compatibility problems with the exclusion a number of technical characteristics and technical requirements. The problem of pigment is a, which also relates to other relevant disciplines, such as the school colors, ceramics, and physical and chemical aspects of technology. Ceramic pigment technology selection and use of significant, direct impact on the quality of the product is related to the economic efficiency of enterprises. In the past, the name refers to ceramic pigment ceramic decoration applied to the whole color of raw materials (including high temperature and low temperature), embraces a wide range; and pigment refers to the low-temperature sintering ceramics for decorative paint products, only is a type of ceramic pigment only. However, the academic sector and the majority of the ceramic business, whether it is paint or stain, used to name the two can be interchangeable, staggered use, there is no prejudice.
　　1、Ceramic pigment adaptation conditions.
　　In ceramic production, the different variety of ceramic products used in paint pigment and should be able to meet the requirements of the actual production process, capable of forming the decorative effect is expected to raise the grade of products. At present, the use of sanitary ceramic products ceramic pigment and ceramic pigments, ceramics for daily use such as to be more than the rich. Sanitary ceramic products, decorative ornaments in the color method, has been divided into underglazed colors,glaze, color glaze, color, colored glaze and color make-up of several aspects of soil.
　　However, the pigment Although many types of decorative techniques, but the use of effects and the range of options have their advantages and disadvantages in the use of options should be strict. For example, is expected to underglazed underglazed color color decoration on top is then covered with a layer of transparent glaze, flower color patterns in underglazed face with a good sense of decorative glass. However, due to the high sintering temperature (1200-1320 degrees), the pigment may choose instead a narrower range of species; type of glaze color pigment painted in glazed surfaces, the use of low-temperature firing, the pigment attached to the surface glaze , due to the low color temperature bake (650-830 degrees), the pigment has available a wide range of advantages.
　　However, because of its pigment in the glaze on, easy to produce pigment in the issue of dissolution of metal compounds;technology sector in the glaze color and glaze color underglazed between the (firing temperature of 1100-1200 degrees), the pigment particles in the glaze layer of the middle of a hazy hue of beauty, but also the type of pigment used is limited;color pigment used to blending into the blank inside, so that the excellent effect of the formation of ceramic products,transparent glaze on the surface in general; glaze is to direct the introduction of pigment and glaze paint, so that the formation of colored glaze glaze (firing temperature of 1150-1280 degrees); there is a will be added to the insoluble pigment in kaolin , made of pottery clothing (also known as soil make-up) for the decoration of ceramics, known as the color make-up soil, soil makeup can cover such a dirty brick tiles, role a lot. Make-up but still need to stain the surface soil layer of transparent glaze(sintering temperature of 1150-1250 degrees), to increase the role of protection and light.
　　In actual use in a variety of ceramic pigment and paint have different firing range, the temperature is too high and too low will adversely affect the fineness. Some firing a wide range of pigment, such as chrome-tin pink, bluelike. Both can be used for high-temperature sintering underglazed color and glaze color can be used in low-temperature sintering, and their results are excellent fineness. Fineness of the pigment and the scope of some fixed, use a lot of taboo, such as lead acid antimony pigments, can be used only low-temperature glaze color and glaze decoration products, if more than temperature, while the loss of color. In addition to sintering temperature, there are a considerable number of pigment and paint flames on the atmosphere of the kiln when firing very sensitive, such as copper oxide pigments, when in a green flame oxidation, and in the reduction will be shown when the flame red, color very large changes.
　　In full knowledge of a variety of process performance ceramic pigment, the pigment should also understand the other aspects, such as ceramic pigment of fineness (the type commonly used pigment), the use of atmosphere temperature and flame characteristics, color range and taboo requests should not be ignored.
　　2、Ceramic pigment commonly used and deployment requirements.
　　Building sanitary ceramics products tend to glaze colorful decoration, used by more and more types of pigment. With advances in technology, modern pigments used in ceramic industry the emergence of new products and new types of use. Such as the rare earth in recent years nano-ceramic materials and ceramic color pigments, such as the type of people to bring a fresh new feeling. Here only the conventional ceramic pigment type effect with the use of varieties described below because these pigment is still the most important varieties of decorative materials.
