Colored high-class daily delicate porcelain and preparation method thereof
The invention relates to a ceramic product and in particular relates to a colored high-class daily delicate porcelain and a preparation method thereof. The colored high-class daily delicate porcelain is prepared by a method comprising the steps of performing high-temperature biscuit firing on a colored greenware, spraying a colorless transparent glaze, performing medium-temperature glazed firing, and firing for two times, wherein the colored greenware is prepared from the following raw materials in percentage by mass: 40-50% of calcined calcium phosphate,10-15% of feldspars, 8-15% of quartz, 30-40% of clay and 1-5% of an additional pigment. According to the preparation method provided by the invention, calcium phosphate is pre-calcined to eliminate internal stress, and the qualified rate is high; and according to the reasonably designed raw material proportions and the preparation method, the colored greenware is fired for the first time, the prepared colored high-class daily delicate porcelain is thin in porcelain body, uniform in color and good in translucency, and has colored glaze gloss, and a glazed layer can prevent harmful elements from seepage and is nontoxic, green and environment-friendly.
