Abstract

The invention provides a preparation method of Jun porcelain cyan glaze. The Jun porcelain cyan glaze is prepared form, by weight, 20 to 25 parts of melilith, 12 to 18 parts of white feldspar, 10 to 15 parts of quartz stone, 10 to 15 parts of calcite, 10 to 12 parts of fluorite, 5 to 7 parts of plant ash, 4 to 6 parts of Rulan stone, 3 to 5 parts of cobalt oxide, 3 to 5 parts of iron oxide, 3 to 5parts of zirconium oxide, 2 to 4 parts of zinc oxide, 2 to 4 parts of aluminium oxide, 2 to 3 parts of stannic oxide, and 8 to 10 parts of frit through certain processing technology; and finished products are obtained via coating of biscuits with a glaze slurry, an accessory ingredient, and an additive. The Jun porcelain cyan glaze prepared via the production method is crystal clear in color, anda problem in conventional production method that the color of Jun porcelain is monotonous and uncontrollable is solved.

Description

Technical field [0001] The invention relates to the technical field of Jun porcelain processing, in particular to a preparation method of Jun porcelain blue glaze. Background technique [0002] Jun Porcelain is known as the first of China's "Five Famous Porcelains", and has the reputation of "Gold has a price and Jun is priceless" and "A family has ten thousand abilities, not as good as one Jun porcelain". Jun porcelain is famous for its unique art of kiln transformation. However, the yield of Jun porcelain is low, with a yield of only 30%. The finest Jun porcelain is even rarer. This is mainly because Jun porcelain is affected by many factors in the firing process, and each link may directly lead to the failure of Jun porcelain production. Among them, the temperature change in the kiln, the heating rate, the glazing method, etc. particularly affect the production process of Jun porcelain. important influence. [0003] The kiln change of Jun porcelain refers to that the glaze on ...
