Abstract

The invention relates to a mud glaze formula for high-temperature firing of bone daily porcelain, and belongs to the technical field of ceramic products. The pug and the glaze are prepared from the following formula components in parts by weight: pug: 70-80 parts of talc, 3-4 parts of bone charcoal powder, 3-6 parts of feldspar, 4-7 parts of bentonite, 91-3 parts of Datong soil and 0.2-0.5 part ofsodium humate; glaze: 55-62 parts of potassium feldspar, 9-12 parts of quartz, 9-11 parts of Longyan clay, 3-4 parts of lepidolite, 3-5 parts of zinc oxide, 9-10 parts of waste porcelain powder and 2-3 parts of bone black powder. With performance of pug and glaze preparation, molding, drying, glazing and high-temperature firing, the product is obtained, the firing time is 8-12 hours, and the highest firing temperature is 1280-1320 DEG C. The novel bone daily-use porcelain fired by the method is good in transparency, strength and whiteness, smooth and clean, and high in ornamental value, so that the novel bone daily-use porcelain has a wide application prospect.
