Embodiment 1
[0011] Embodiment 1: 40% potassium feldspar, 15% quartz, 5% kaolin, 5% loess, 10% talc, 5% limestone, 13% bone ash and 7% iron oxide are mixed by mass percentage , finely ground to 250 mesh, glaze slurry specific gravity 1.6g / cm 3 ; Preparation method of crystal nucleating agent: mix 30% kaolin and 70% iron oxide according to mass percentage, ball mill, calcinate at 1270°C, cool and crush into particles of about 1mm; pre-embed crystal nucleating agent in green body to form In the position of the crystal, the pre-buried holes are usually around =1mm, and the number and distribution can be adjusted according to the needs; the basic glaze is evenly applied to the ceramic body with the pre-embedded crystal nucleus agent, and the thickness of the glaze layer is controlled at 0.7mm to obtain Semi-finished product: burn the semi-finished product with an oxidizing flame at 1270°C, keep it warm for 20 minutes and then cool it down to room temperature naturally.
Embodiment 2
[0012] Embodiment 2: 45% potassium feldspar, 10% quartz, 6% kaolin, 6% loess, 8% talc, 5% limestone, 12% bone ash and 8% iron oxide are mixed by mass percentage , finely ground to 250 mesh, glaze slurry specific gravity 1.7g / cm 3 ; Preparation method of crystal nucleating agent: mix 50% kaolin and 50% iron oxide according to mass percentage, ball mill, calcinate at 1290°C, cool and crush into particles of about 1mm; pre-embed crystal nucleating agent in green body to form At the position of the crystal, the pre-buried holes are usually around =1mm, and the number and distribution can be adjusted according to the needs; the basic glaze is evenly applied to the ceramic body with the pre-embedded crystal nucleus agent, and the thickness of the glaze layer is controlled at 0.9mm. Semi-finished product: burn the semi-finished product with an oxidizing flame at 1290°C, keep it warm for 30 minutes and then cool it down to room temperature naturally.
Embodiment 3
[0013] Embodiment 3: 42% potassium feldspar, 12% quartz, 8% kaolin, 5% loess, 8% talc, 6% limestone, 12% bone ash and 7% iron oxide are mixed by mass percentage , finely ground to 250 mesh, glaze slurry specific gravity 1.7g / cm 3 ; Preparation method of crystal nucleating agent: mix 70% kaolin and 30% iron oxide according to mass percentage, ball mill, calcinate at 1280°C, cool and crush into particles of about 1mm; pre-embed crystal nucleating agent in green body to form In the position of the crystal, the pre-buried holes are usually around =1mm, and the number and distribution can be adjusted according to the needs; the basic glaze is evenly applied to the ceramic body with the pre-embedded crystal nucleus agent, and the thickness of the glaze layer is controlled at 0.8mm. Semi-finished product: burn the semi-finished product with an oxidizing flame at 1280°C, keep it warm for 10 minutes and then cool it down to room temperature naturally.
