The invention discloses a matte glaze and a preparation method thereof. The matte glaze comprises the following components by weight: 1-5 parts of zinc oxide, 5-15 parts of barium carbonate, 0-15 parts of zirconium silicate, 10-25 parts of potassium feldspar, 10-20 parts of kaolin, 5-15 parts of calcite, 5-15 parts of calcined talcum powder, 20-35 parts of a matte frit and 0.5-1 part of an additive. Specifically, the matte frit comprises the following components by weight: 30-50 parts of SiO2, 15-20 parts of Al2O3, 0.01-0.5 part of Fe2O3, 3-10 parts of CaO, 0.5-5 parts of MgO, 1-5 parts of K2O, 3-10 parts of Na2O, 3-10 parts of ZnO, 0.1-1 part of B2O3 and 10-25 parts of BaO. By introducing the matte frit, the melting temperature of the formula is lowered, the firing range of the formula isbroadened, and the glaze texture achieves a fine matte effect.

The invention discloses an art glaze based on ceramic waste and a preparation method thereof, and relates to the technical field of ceramic glazes, the art glaze is prepared from the following components by weight: 30-50 parts of frit, 5-15 parts of quartz, 10-20 parts of calcite, 3-6 parts of burnt zinc, 6-10 parts of titanium dioxide, 25-35 parts of barium carbonate, 10-25 parts of modified ceramic powder, 2-4 parts of iron oxide red, and 3-6 parts of talc. According to the invention, high-valued recycling of the ceramic waste is realized, waste is turned into wealth, the production cost and environmental load are remarkably reduced, and the obtained art glaze is flat and bright in glaze surface, unsophisticated and elegant in color and lustre, warm and moist in texture like jade, and excellent in thermal shock resistance and weather resistance. According to the technology, the problems that a traditional glaze layer is prone to cracking and pinhole defects are effectively solved, double improvement of environmental protection benefits and product quality is achieved, and the technology has extremely high market popularization value.
