Jun porcelain sky blue glaze and preparation method thereof

Abstract

The invention relates to the technical field of jun porcelain glaze, in particular to jun porcelain sky blue glaze and a preparation method thereof. Frit is prepared from the following raw materials in parts by weight: feldspar, quartz, fluorite, talc, wollastonite and a phosphorus compound. The glaze slip is prepared from the following raw materials in parts by weight: frit, clay, ferric oxide, strontium carbonate, copper oxide, titanium oxide, cobalt oxide, manganese oxide and hydroxypropyl methyl cellulose; through quartz, fluorite, talc and a phosphorus compound, glaze pinhole defects areeliminated, glaze gloss is increased, finished product quality is improved, and glaze gloss is increased. The amounts of feldspar and quartz are reasonably configured, and a good middle layer is formed between the glaze layer and the green body so that the green body and the glaze are tightly combined; the thermal stress between the blank and the glaze is uniform, the stress between the blank andthe glaze is weakened, and the mechanical strength of the Jun porcelain is improved; through high-temperature 'reducing flame' and twice low-temperature 'oxidizing flame' calcination, colored metal generates different reactions at different temperatures to display different colors so that the sky blue glaze is variable in color.

Description

technical field [0001] The invention relates to the technical field of Jun porcelain glaze, in particular to a Jun porcelain sky blue glaze and a preparation method thereof. Background technique [0002] Jun porcelain began in the Tang Dynasty and flourished in the Song Dynasty. It is one of the five famous porcelains in ancient China. It occupies an important position in the history of the development of Jun porcelain in the world. Since ancient times, there have been sayings that "gold is priceless and Jun porcelain is priceless" and "a family is rich, but it is not as good as a piece of Jun porcelain". The artistic characteristics of "Wancai" are widely loved by Jun porcelain lovers. [0003] Sky blue glaze is the name of the glaze color of porcelain; it evolved from "sky blue" and was created and fired in the Kangxi period of the Qing Dynasty. The glaze color is light and bluish, like sky blue, hence the name. . [0004] Glaze refers to the glassy thin layer covered o...

AI Technical Summary

Problems solved by technology

[0004] Glaze refers to the glassy thin layer covered on the ceramic body, but its composition is more complex than glass, and its properties and microstructure are also quite different from glass, such as its high temperature viscosity is much greater than that of glass; its composition and The preparation process is similar to the blank and different from glass; the function of glaze is to improve the surface properties of ceramic products, make the surface of the product smooth, impermeable to liquid and gas, and not easy to be stained; secondly, it can improve the mechanical strength of the product, Electrical properties, chemical stability and thermal stability; glaze also plays a decorative role on the body, it can cover the bad color and rough surface of the body; many glazes such as color glaze, matte glaze, placer gold glaze, crystallization glaze, etc. have unique Decorative effect; but most of the fired products of sky blue glaze in the prior art have a single color, which is suitable for antique families, but it is difficult to enter most families; for this reason, a kind of sky blue glaze with gradual changes in color and diverse styles is proposed, so that Sky blue glaze can also satisfy modern people's pursuit of fashion, expand the user group of sky blue glazed Jun porcelain, and promote the use of sky blue glazed Jun porcelain
