Abstract

The invention relates to the technical field of ceramic glazes, in particular to a copper red matt kiln-changing glaze and a preparation method thereof. The copper-red matt kiln glaze is composed of a bottom glaze and a top glaze. The bottom glaze includes refined potassium feldspar, animal bone ash, refined quartz, lime, talc, refined cordierite, silicon carbonate, copper oxide, tin oxide, zinc oxide, Alumina, barium carbonate, and boron; topcoats include refined potassium feldspar, refined quartz, talc, zirconium phosphate, titanium oxide, tin oxide, frit, refined dolomite, zinc oxide, and copper oxide. The preparation method comprises: preparing the bottom glaze slurry; preparing the top glaze slurry; preparing the bottom glaze; and preparing the top glaze. The invention solves the problems of high difficulty in making kiln-transformed glaze and poor kiln-transformed effect in the prior art, and the prepared kiln-transformed glaze has excellent performance, and the thermal stability, water absorption rate and dissolution of lead and cadmium of the product can meet the requirements of daily-use ceramic products. related standards.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a copper red matt kiln-changing glaze and a preparation method thereof. Background technique [0002] Porcelain is made of porcelain stone, kaolin, quartz stone, mullite, etc., and the surface is covered with glass glaze or painted objects. Porcelain is formed by firing at a high temperature (about 1280°C-1400°C) in a kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to different temperatures. Sintered porcelain bodies generally contain less than 3% iron and are impermeable. Because of their relatively low cost and wear-resistant and impermeable properties, they are widely used by people all over the world. [0003] When firing porcelain, anyone who finds that the shape or glaze color is not the expected shape or glaze color after opening the kiln, so that the handed down porcelain sometimes has a special situation, can be...
