[0013] Example 1
[0014] 1) Preparation of blanks: 600kg east mud, 400kg west mud, MnCl 2 10kg is mixed uniformly, after grinding, press filtering, vacuum mud smelting, and aging, the blank is obtained;
[0015] 2) Green body forming: the green body is made into 100 can blanks with outer diameter=250mm and capacity=3000ml;
[0016] 3) The green body is dried: the green body is dried;
[0017] 4) Green body firing: Put the dried green body into a kiln, raise it to 250℃ at a temperature rise of 20℃ per hour, then raise it to 700℃ at a temperature rise of 80℃ per hour, and then The temperature rise rate of 40℃ per hour rises to 1150℃, the heating is stopped, and the kiln is discharged after cooling; during the heating process, when the temperature rises to 700℃, pressurize the body to 10MPa, when the temperature rises to 1100℃, Stop pressurization.
[0018] The finished products of Nixing pottery were filled with water one by one and put directly into the gas stove to heat without crac...

[0019] Example 2
[0020] 1) Preparation of blanks: 600kg east mud, 400kg west mud, MnCl 2 30kg is mixed uniformly, after grinding, press filtering, vacuum mud smelting and aging process, the blank is obtained;
[0021] 2) Green body forming: the green body is made into 100 can blanks with outer diameter=250mm and capacity=3000ml;
[0022] 3) The green body is dried: the green body is dried;
[0023] 4) Green body firing: Put the dried green body into a kiln, and raise it to 350℃ at a heating rate of 30℃ per hour, then raise it to 700℃ at a heating rate of 100℃ per hour, and then When the temperature rises at 60°C per hour, the heating rate rises to 1200°C, stops heating, cools and exits the kiln; during the heating process, when the temperature rises to 700°C, pressurize the body to 15MPa, and when the temperature rises to 1100°C, Stop pressurization.
