[0031] Example 1
[0032] The process of preparing Jun porcelain with blue motley composite Tang Jun glaze includes the following steps:
[0033] Step one: firing plain tires
[0034] Mix 65 parts of kaolin, 20 parts of soda stone, 8 parts of wood knot clay and 7 parts of quartz sand evenly, stir with water at a mass ratio of 1:1 to obtain a mixture; grind the mixture into a slurry with a ball mill and finely grind it for 80 minutes. The fineness reaches 250 meshes; the obtained mud is formed into a plain tire by hand. The plain tire is allowed to stand to dry, and then enter the kiln for sintering at 860℃ for 10 hours, and then cool to room temperature with the furnace to obtain the fired plain tire for use. ;
[0035] Step two, prepare the blue base glaze
[0036] Mix 35 parts of yellow feldspar, 10 parts of calcite, 10 parts of quartz stone, 10 parts of black soil, 18 parts of copper ore and 0.2 parts of cobalt oxide into the ball mill, and add equal mass of water to the ball mill ...

[0043] Example 2
[0044] The process of preparing Jun porcelain with blue motley composite Tang Jun glaze includes the following steps:
[0045] Step one: firing plain tires
[0046] Mix 65 parts of kaolin, 20 parts of soda stone, 8 parts of wood knot clay and 7 parts of quartz sand evenly, stir with water at a mass ratio of 1:1 to obtain a mixture; grind the mixture into a slurry with a ball mill and finely grind it for 80 minutes. The fineness reaches 300 meshes; the obtained slurry is poured into a plain tire, which is left to dry and then enters a kiln for biscuits at 880°C for 10 hours, and is cooled to room temperature with the furnace to obtain a fired plain tire for use;
[0047] Step two, prepare the blue base glaze
[0048] Mix 37 parts of yellow feldspar, 11 parts of calcite, 11 parts of quartz stone, 12 parts of black soil, 22 parts of copper ore and 0.8 parts of cobalt oxide into the ball mill, and add equal mass of water to the ball mill to form a slurry with a fineness ...

[0055] Example 3
[0056] The process of preparing Jun porcelain with blue motley composite Tang Jun glaze includes the following steps:
[0057] Step one: firing plain tires
[0058] Mix 65 parts of kaolin, 20 parts of soda stone, 8 parts of wood knot clay and 7 parts of quartz sand, and stir with water at a mass ratio of 1:1 to obtain a mixture; grind the mixture into a slurry with a ball mill and finely grind it for 80 minutes. The fineness reaches 250 meshes; the obtained mud is formed into a plain tyre by hand. The plain tyre is allowed to stand to dry and then enters the kiln for biscuits at 900℃ for 10 hours, and then is cooled to room temperature to obtain the fired plain tyre for use. ;
[0059] Step two, prepare the blue base glaze
[0060] Mix 40 parts of yellow feldspar, 13 parts of calcite, 13 parts of quartz stone, 15 parts of black soil, 22 parts of copper ore and 1.3 parts of cobalt oxide into the ball mill, and add equal mass of water to the ball mill to form a slurry...
