Abstract

The invention discloses light greenish blue matte glaze for a pottery product and a preparation method of the light greenish blue matte glaze. A process formula of the light greenish blue matte glaze is prepared from the following components in percentage by mass: 27 to 32 percent of feldspar powder, 12 to 17 percent of calcium carbonate, 6 to 8 percent of dolomite, 7 to 14 percent of talc, 6 to 8 percent of barium carbonate, 2 to 9 percent of zirconium silicate, 5 to 10 percent of frit, 0 to 4 percent of zinc oxide, 0 to 9 percent of aluminum oxide, 3 to 5 percent of carnelian cobble and 4 to 10 percent of kaolin. The preparation method comprises the following steps: weighing all the components according to the formula, then fully mixing, and adding into a grinding tank; adding water of which the weight is equivalent to 45 to 50 percent of the weight of dry powder, and grinding for 10 to 15 hours, wherein the ratio of materials to spheres to the water is 1:1.5:0.65; afterwards, deironing and sieving glaze slip subjected to ball milling, and adjusting the concentration until the true specific gravity is 50 to 54 degrees; glazing the pottery product by adopting spraying, soaking or other decoration methods, wherein the thickness of a glaze layer is 1 to 3mm; drying, then feeding into a kiln, performing oxidation firing at the temperature of 1200 to 1235DEG C, naturally cooling and then discharging from the kiln. The prepared light greenish blue matte glaze has the advantages of stable color, high rate of finished product and high artistic value.

Description

technical field [0001] The invention relates to the technical field of craft ceramics, in particular to a powder blue matt glaze for pottery products and a preparation method thereof. Background technique [0002] The production of traditional Chinese celadon is mainly realized through the control of reducing atmosphere firing. During the firing process, the trivalent Fe in the glaze layer is reduced to divalent Fe according to the strength of the reducing atmosphere. Due to the difference in the content of divalent and trivalent iron ions, different color tones appear, such as pinkish green, shadow There are different shades of green, sunny after rain, holly, and plum green. It is difficult to control the atmosphere in the reduction stage during the whole firing process, and it is easy to cause different degrees of deviation in the glaze color of the product, smoke, color difference and other problems, and the yield rate is low. Contents of the invention [0003] The pu...
