Embodiment 1
[0023] A high-density turquoise glaze, made of the following raw materials in parts by weight: silicon dioxide 39, talc powder 11, cerium oxide 7.6, lanthanum oxide 5.1, zirconium oxide 4.7, praseodymium oxide 4.4, cobalt oxide 4.2, titanium dioxide 3.8, Nano Zinc Oxide 3.2, Denatured Wollastonite 3.3, Chlorite 4.1, Salt 1.2.
[0024] For the denatured wollastonite, pulverize the wollastonite to 160 mesh, heat the wollastonite to 1200°C in vacuum, wait for the wollastonite to cool naturally to 200°C, add a mass percentage concentration twice the weight of the wollastonite to the wollastonite 5% ammonium acetate solution, keep warm for 40 minutes, then heat at 3°C / min to 800°C, keep warm for 30 minutes, and cool down to room temperature naturally, which can improve the stability and corrosion resistance of the glaze and avoid the growth of the glaze Bacteria and discoloration, keep the glaze smooth, get denatured wollastonite.

Embodiment 2
[0037]A high-density turquoise glaze, made of the following raw materials in parts by weight: silicon dioxide 40, talcum powder 12, cerium oxide 8.0, lanthanum oxide 5.6, zirconia 5.1, praseodymium oxide 4.9, cobalt oxide 4.7, titanium dioxide 4.2, nano zinc oxide 3.8, denatured wollastonite 3.6, chlorite 4.4, table salt 1.5.
[0038] For the denatured wollastonite, pulverize the wollastonite to 180 mesh, heat the wollastonite to 1300°C in vacuum, wait for the wollastonite to cool naturally to 230°C, add a concentration of 2.5 times the weight of the wollastonite to the wollastonite It is 6% ammonium acetate solution, heat for 50 minutes, then heat to 850°C at a speed of 3.5°C / min, hold for 35 minutes, and cool to room temperature naturally, which can improve the stability and corrosion resistance of the glaze and avoid the growth of the glaze. Bacteria and discoloration, keep the glaze smooth, get denatured wollastonite.
