Abstract

The invention discloses a reddish-black jun porcelain glaze prepared by utilizing metal copper and iron and a preparation method of the reddish-black jun porcelain glaze, belonging to the preparation filed of ceramic glazes. The preparation method of the reddish-black jun porcelain glaze comprises the following steps of: (1), mixing the following components in percentage by weight: 45%-50% of feldspar, 20%-30% of quartz, 14%-17% of calcite, 5%-7% of talcum, 2.5%-3.5% of kaolin and 2.9%-3.5% of calcium phosphate, so as to obtain a material mixture, and adding and sufficiently mixing the following materials (based on the total weight of the material mixture): 0.3%-2% of ZnO, 1.5%-4% of SnO2, 0.2%-2% of Fe, 0.1%-1.5% of Cu, 0.1%-0.5% of cellulose and 0.5%-1.5% of sodium tripolyphosphate, so as to obtain a glaze mixture; (2), carrying out wet-process ball-milling on the glaze mixture to obtain glaze pulp; (3), applying the glaze pulp on a biscuit firing billet for firing for 20 minutes-40minutes in a neutral or weak oxidative atmosphere, and cooling to obtain the reddish-black jun porcelain glaze. The preparation method of the reddish-black jun porcelain glaze is simple and easy to implement, board in firing temperature range and easily controllable in firing atmosphere. And the reddish-black jun porcelain glaze obtained by the preparation method disclosed by the invention is simple in composition, smooth and flat in glazed surface, high in stability and bright in reddish-black color.

Description

technical field [0001] The invention belongs to the field of ceramic glaze preparation, and relates to a preparation method of Jun enamel, in particular to a sky blue Jun enamel prepared by using metal copper and iron and a preparation method thereof. Background technique [0002] Jun porcelain glaze is a very precious glaze. The general Jun porcelain glaze is made by adding minerals containing copper and iron to the basic glaze, and firing in an atmosphere of oxidation first and then reduction. However, the conditions required by these atmospheres are extremely difficult to control, so there is a saying that "ten kilns are not successful in firing Jun porcelain", "three points depend on the shape of the vessel, five points depend on firing, and two points depend on luck". become very difficult. [0003] With the improvement of modern detection technology, some scholars have conducted in-depth research on the microstructure and kiln transformation mechanism of ancient Jun ...
