Cracked lujun glaze

Abstract

The invention provides a cracked lujun glaze. The cracked lujun glaze is characterized by being prepared from the following raw materials in parts by weight: 15 to 21 parts of local feldspar from Yuzhou, Henan, China, 7 to 13 parts of quartz, 9 to 15 parts of calcite, 4 to 6 parts of gravel, 2 to 3 parts of copper oxide, 37 to 43 parts of melilite, 4 to 6 parts of white feldspar, 3 to 5 parts of talcum, 2.5 to 3.5 parts of zinc oxide and 0.25 to 0.75 parts of stannic oxide. Compared with the prior art, by scientifically and reasonably proportioning the raw materials and controlling a sinteringprocess, the sintered cracked lujun glaze disclosed by the invention has the advantages of natural color, has crackle, high jade texture, high rate of a finished product and rare floating light; in addition, a large kiln is adopted for firing, a firing method adopts a gas firing mode, and the rate of the finished product can reach 90 percent or above.

Description

technical field [0001] The invention relates to a glaze material, in particular to an open-slice furnace glaze. Background technique [0002] Jun Porcelain is one of the five famous porcelains of the Song Dynasty in my country. It is famous for its blue sky and colorful "kiln change" glaze color of "after the rain, the sky is sunny and red, and the setting sun is purple and green". It has created many historical masterpieces in the history of ancient ceramic craftsmanship. Exemplary work. The "Lu Jun Glaze" in Jun porcelain is colorful, jade-run and crystal-clear, the glaze surface is natural but not rigid, mixed but not chaotic, coupled with unpredictable markings, its natural effect is far beyond that of other Jun porcelains. Therefore, it has become a bright pearl in the garden of Juncibai. However, the existing glaze formulations for firing Lujun glaze are easy to lose and cannot be controlled during the firing process. Traditional firing methods are all fired in small ...

AI Technical Summary

Problems solved by technology

However, the existing glaze formulations for firing Lujun glaze are easy to lose and cannot be controlled during the firing process. Traditional firing methods are all fired in small kilns, and the firing methods also use traditional charcoal, coal, and firewood. , one kiln can only fire one piece of larger blank or 2-3 pieces of smaller blank, and the success rate of this firing method is extremely low, and it is still at the stage of "ten kiln nine failures"
