Abstract

The invention discloses a blue glaze and a preparation method thereof. The blue glaze is prepared from, by weight, 40-48% of albite, 18-25% of quartz powder, 8-12% of kaolin and 21-25% of wollastonite. The glaze enables a porcelain fired by the glaze to be dark in color and luster, uniform in concentration, stable in color generation, non-flowing and non-cracking in glaze surface, smooth in hand feeling, durable, wear-resistant, good in smoothness and thermal stability, wide in firing range, suitable for medium-temperature oxidizing atmosphere and high-temperature reducing atmosphere and suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of glazes, in particular to a Qilan glaze and a preparation method thereof. Background technique [0002] Treasures of traditional Chinese porcelain making crafts. Also known as "accumulating blue glaze", "sacrificing blue glaze" and "ji blue glaze". Both Ming and Qing blue glazes are called "Ji blue", a kind of high temperature lime alkali glaze. The green body is glazed and fired at high temperature for the first time. The color is deep, the glaze does not flow or crack, the color tone is uniform, and the color is relatively stable. Its glaze color is as blue as the deep sea, the glaze surface is even and stable, and later generations call it "Jiqing". Because of its stable and bright color like gemstones, it is also regarded as juxtaposed with white glaze and red glaze. The three "top grades" of Xuande color glaze porcelain. The craftsmanship inherits the tradition of the Yuan Dynasty, and the firing...
