The invention relates to a high-temperature domestic porcelain metallic bright glaze and a product decorated by the same. The bright glaze produced by using natural mineral raw materials and industrial pure raw materials comprises the following materials by weight percent: 10-25 percent of potassium feldspar, 10-30 percent of albite, 0-35 percent of quartz, 0-10 percent of barium carbonate, 0-10 percent of wollastonite, 0-10 percent of kaolin, 0-5 percent of zinc oxide, 1-10 percent of aluminum oxide, 1-10 percent of bone ash, 1-5 percent of purple clay and 10-35 percent of ferric phosphate, and the glaze is obtained by mixing, ball-milling and screening the raw materials. The fabrication technology of the glaze is basically the same as the common porcelain glaze, the cost is low, not only can the pure color be guaranteed through redesigning of the formula of the glaze, but also the burning temperature of the glaze is increased to 1380 DGE C, so that the decoration effect of domestic porcelain is greatly enriched, and the high-temperature domestic porcelain metallic bright glaze has wide application prospect.

The invention discloses a process for preparing spherical nanometer spinel zaffre by the hydrothermal method. The process comprises the following steps: weighing and putting cobalt chloride and aluminum chloride according to a mol ratio of Co<2+> : Al <3+> = 1:2, putting the materials into a beaker, adding a proper amount of deionized water and carrying out uniform stirring on a magnetic stirrer;adding a sodium hydroxide solution drop by drop until the pH value of the mixture in the beaker is 13 and continuing stirring; adding mixed liquor of triethanolamine and glycerol with a volume fraction of 6 to 18% and resuming stirring; carrying out hydrothermal cultivation on the mixed solution at a temperature of 245 DEG C for 20 to 40 hours and taking the mixed solution out for natural coolingat room temperature; repeatedly rinsing the hydrothermal cultivation resultant material in liquid phase until the pH value equals 7 and putting the resultant material into a baking oven for drying attemperature of 60 DEG C so as to obtain spherical products with particle size less than 100 nm. The advantages of the invention are as follows: liquid phase hydrothermal cultivation is employed and composite organic matters are added; therefore, nanometer spherical powder is formed directly without calcining, energy consumption is relatively low, and no environmental pollution is generated.

The invention discloses a bleed ceramic ink and a preparation method thereof, and relates to the technical field of architectural ceramic decoration. The bleeding ceramic ink consists of 30-75 parts of ruthenium alkyl salicylate, 20-75 parts of solvent, 0.1-4 parts of penetrating agent and 0.1-4 parts of complexing agent in parts by weight. The bleed ceramic ink prepared by the preparation method of the present invention can be directly sprayed onto the ceramic surface by an inkjet printer, the color is pure, the bleed depth can reach 1.7-2.8mm, and it shows bleed with high resolution and strong three-dimensional effect. Flower decoration effect.
