The invention also relates to a method for firing an apple green crystalline glaze by using the apple green crystalline glaze, which comprises the following steps:
(1) weighing the components according to the using amounts to prepare an apple green crystalline glaze;
(2) mixing the apple green crystalline glaze obtained in the step (1) with water, settling, and then ball-milling for 12-24 hours and sieving with a 100-200-mesh sieve to obtain a mixed solution; the mass ratio of the apple green crystalline glaze to water is 100: 70-80 parts;
(3) and (3) firstly, firing the ceramic body for 5 hours to 800 ℃, then soaking the biscuit fired ceramic body into the mixed liquid obtained in the step (2), taking out after 2-3 seconds, firing for 12 hours in an electric kiln, and cooling to obtain the ceramic product with the apple green crystal glaze on the surface.
Further, preferably, the electric kiln firing procedure is as follows:
the first stage is as follows: heating from 20 deg.C to 150 deg.C for 150 min;
and a second stage: heating from 150 deg.C to 300 deg.C for 100 min;
and a third stage: heating from 300 deg.C to 800 deg.C for 200 min;
a fourth stage: heating from 800 deg.C to 1240 deg.C for 240 min;
the fifth stage: raising the temperature from 1240 ℃ to 1250 ℃ for 20 min;
the sixth stage: keeping the temperature at 1250 ℃ for 10 min.
In order to achieve specific artistic effect, the ceramic blank is biscuit-fired at 800 ℃, then apple green crystal glaze with the thickness of 1-2 mm is coated, and the apple green crystal glaze with the special effect of matt and slightly green apple crystal can be obtained after the blank is fired for 12 hours at 1250 ℃.
Compared with the prior art, the invention has the following beneficial effects:
the invention has simple formula, convenient operation and low cost; the apple green ceramic product with the apple green crystallization effect can be obtained, and is exquisite, beautiful and strong in artistic effect; more porcelains with special artistic effects can be obtained by superposing the glaze materials.
(IV) detailed description of the preferred embodiments
The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto:
example 1:
the formula of the apple green crystalline glaze comprises the following components in parts by mass: 21.78 parts of potash feldspar, 6.73 parts of calcite, 1.95 parts of zinc oxide, 2.99 parts of kaolin, 0.40 part of copper oxide, 0.30 part of lithium carbonate and 0.20 part of quartz.
The firing method comprises the following steps: mixing the apple green crystalline glaze with water according to the mass ratio of 100: 75 mixing, floating and sieving by a 120-mesh sieve to obtain a mixed solution;
firstly, firing the ceramic body for 5h to 800 ℃, then immersing the biscuit fired body into the obtained mixed solution, taking out after 2-3 s, firing for 12 h in an electric kiln at 1250 ℃, and cooling to obtain the ceramic product with strong artistic sense and apple green crystallization effect.
Firing temperature profile:
and (3) electric kiln sintering: putting the green body into a kiln, and burning the green body from 20 ℃ to 150 ℃ in 150 minutes in the first stage to remove the moisture in the green body; in the second stage, the temperature is heated to 300 ℃ from 150 ℃ in 100 minutes, and the moisture is removed; in the third stage, the temperature is increased from 300 ℃ to 800 ℃ through 200 minutes, so that the blank is stable; the fourth stage is to burn from 800 ℃ to 1240 ℃ through 240 minutes to fully melt the glaze; the fifth stage is to burn from 1240 ℃ to 1250 ℃ through 20 minutes and keep the temperature for 10 minutes to fully finish the glaze crystallization. Then naturally cooling, and discharging from the kiln when the temperature reaches 100 ℃.
Example 2:
the formula of the apple green crystalline glaze comprises the following components in parts by mass: 21.78 parts of potash feldspar, 6.73 parts of calcite, 1.95 parts of zinc oxide, 2.99 parts of kaolin, 0.40 part of copper oxide, 0.10 part of lithium carbonate and 0.20 part of quartz. The firing method and firing profile were the same as in example 1.
As titanium oxide is in the glaze, when the dosage of lithium carbonate is reduced from 0.3 part to 0.1 part, the color development is affected, the opacifying effect becomes strong, and the glaze color becomes opaque green. The glaze effect of the apple green crystal of example 1 was not obtained in the glaze of example 2, but only the glaze effect of the matte translucent green alone was obtained, and the lightness was weakened.
Example 3:
the formula of the apple green crystalline glaze comprises the following components in parts by mass: 21.78 parts of potash feldspar, 6.73 parts of calcite, 1.95 parts of zinc oxide, 2.99 parts of kaolin, 0.40 part of copper oxide, 0.30 part of lithium carbonate and 1 part of quartz. The firing method and firing profile were the same as in example 1.
Example 3 the amount of quartz is increased to 1 part, and the glaze effect is clear light green glaze color, the fluidity is enhanced, and the glaze accumulation phenomenon appears under the glaze.
