Embodiment 1

[0057] A kind of preparation method of middle temperature plum green dragon spring celadon, comprises the following steps:

[0058] a. Green body preparation: the Longquan celadon blank is made into a green body by manual molding or mold molding as required;

[0059] In terms of mass percentage, the formula of the Longquan celadon blank is: 40% of Baoxi china clay, 30% of kaolin, 25% of burnt talc, and 5% of potassium feldspar;

[0060] b. Drying: dry the half-dried biscuit in the shade for 20-24 hours;

[0061] c. Blank trimming: Correct the semi-dry blank, so that the thickness of the blank is uniform, and the edge and ring foot of the blank are smooth;

[0062] d. Moisturizing: Use a sponge or a brush dipped in water to replenish water on the trimmed area of ​​the biscuit to make the surface of the biscuit smooth and flat;

[0063] e. Biscuit firing: put the water-filled biscuit into the shuttle kiln, so that the temperature in the shuttle kiln is evenly raised to 750-800...

Abstract

The invention discloses medium-temperature plum green glaze and medium-temperature plum green Longquan celadon.The medium-temperature plum green glaze is prepared from, by mass, 23-28% of yellowstone basalt glaze earth, 15-22% of limestone, 10-17% of Zijin earth, 20-25% of potassium feldspar, 6-12% quartz, 1-3% of calcined talc and 5-8% of zinc oxide.By increasing content of alkaline metal oxide and alkaline earth metal oxide in the glaze, firing temperature of the medium-temperature plum green glaze is lowered, the medium-temperature plum green glaze can be fired in reducing atmosphere at temperature of 1200-1230 DEG C, firing energy consumption is lowered, and firing cost is saved by 20-25% when compared with that of common formulations; the medium-temperature plum green glaze is stable in color and luster, high in fluidity and capable of meeting batch production requirements; Zijin earth with iron content higher than 10% is used as a main colorant, so that aesthetic requirements of the public on color, luster and texture of crude ore glaze can be met to greatest extent.

Description

technical field [0001] The invention relates to a ceramic glaze, in particular to a medium-temperature plum celadon glaze and a medium-temperature plum celadon celadon. Background technique [0002] Plum celadon glaze is an outstanding celadon glaze variety created and fired by Longquan kilns in the Southern Song Dynasty. ) in a reducing atmosphere, the firing time ranges from 10 to 15 hours, the glaze layer is thick and transparent, green and green, and the color tone is comparable to that of jadeite. [0003] However, the traditional plum celadon not only has a low yield rate but also consumes a lot of energy in the preparation and firing process, which greatly increases the production cost of Longquan celadon products. However, many plum celadon glazes on the market that have been added with chrome green and other pigments are mostly fired at high temperatures, and the color is extremely unnatural. For example, the Chinese invention patent application with the applicati...
