Embodiment 1
[0009] Embodiment 1: Raw materials are prepared in the following parts by weight: SiO 2 58 copies, Al 2 o 3 8 parts, CaO 11.5 parts, ZnO 2.7 parts, BaO 4.4 parts, Na 2 O 3.5 parts, K 2 O 3 parts, B 2 o 3 2 copies, SO 3 0.5 parts, Sb 2 o 3 0.4 parts, colorant (TiO 2 +CeO 2 )TiO 2 3.5 parts, CeO 2 2.5 servings. After the raw materials are prepared, they are fully mixed, put into the melting furnace, melted into molten glass at 1470°C, and pressed into a spherical shape with a particle size of about 30mm at a temperature of 930°C, and then the glass is The ball is cooled to 850°C and put into cold water to temper and form cracks. After drying, put it into a mold and enter it into a shuttle kiln for crystallization. After the crystallization is completed, it will be ground, cut, and polished to obtain a yellow jade pattern glass-ceramic product.
Embodiment 2
[0010] Embodiment 2: Raw materials are prepared in the following parts by weight: SiO 2 54 parts, Al 2 o 3 5 parts, CaO 10 parts, ZnO 6 parts, BaO 3 parts, Na 2 O 3 parts, K 2 O 4 parts, B 2 o 3 3 parts, MgO 2 parts, SO 3 0.2 parts, Sb 2 o 3 0.3 parts, blue colorant (CoO+CuO) CoO 0.05 parts, CuO 0.15 parts. After the raw materials are prepared, they are fully mixed, put into the melting furnace, melted into molten glass at 1470°C, and press the molten glass into an oblate shape with a particle size of about 40mm at a temperature of 910°C. The round glass particles are cooled to 860°C and put into cold water to temper and form cracks. After drying, put it into a mold and enter it into a shuttle kiln for crystallization. After the crystallization is completed, it will be ground, cut, and polished to obtain a blue jade pattern glass-ceramic product.
Embodiment 3
[0011] Embodiment 3: Raw materials are prepared in the following parts by weight: SiO 2 60 parts, Al 2 o 3 6 parts, CaO 12 parts, ZnO 5 parts, BaO 5 parts, Na 2 O 4 parts, K 2 O 3 parts, B 2 o 3 4 parts, MgO 3 parts, SO 3 0.5 parts, Sb 2 o 3 0.2 parts, beige colorant NiO 0.025 parts. After the raw materials are prepared, they are fully mixed, put into the melting furnace, melted into molten glass at 1470°C, and pressed into a cube shape with a particle size of about 20mm at a temperature of 945°C, and then the cube shape The glass particles are cooled to 880°C and put into cold water to temper and form cracks. After drying, put it into the mold, enter the shuttle kiln for crystallization, and after the crystallization is completed, grind, cut, and polish to obtain beige jade pattern glass-ceramic products.
