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.
