The invention relates to a Ru porcelain red, yellow, and blue luminescent
glaze and a preparation method thereof, which can effectively overcome the singular color of Ru porcelain so as to meet the demand of people for artistic effect and enjoyability. The Ru porcelain red, yellow, and blue luminescent
glaze is prepared by utilizing 30 percent to 40 percent of
quartz, 6 percent to 8 percent of
zinc dioxide, 22 percent to 30 percent of
lead oxide, 8 percent to 12 percent of
boric acid, 13 percent to 17 percent of
feldspar, and 2 percent to 4 percent of
sodium carbonate by weight percentage as base materials and adding 13 percent to 17 percent of
rare earth powder with the glue. The added glue added accounts for 40 percent to 50 percent in the sum of the weights of base material and
rare earth powder. The preparation method comprises the steps that: the base materials are melted into glass solution blocks at a temperature
ranging from 1,250 DEGC to 1,300 DEG C, and then crushed into 200 mesh to 300 mesh
fine powder. And then, the base material is mixed with
rare earth powder accounting for 13 percent to 17 percent of the weight of the base materials to obtain the mixture powder. At last, the mixture powder material is added with glue accounting for 40 percent to 50 percent of the weight of the powder material to prepare Ru porcelain red, yellow, and blue luminescent
glaze. With scientific composition, rich raw materials, low cost, simple technique, and easy production, the Ru porcelain red, yellow, and blue luminescent glaze is an innovation in Ru porcelain development and has huge social and
economic benefits.
