Jun porcelain rose violet glaze and preparation method thereof

Abstract

The invention relates to Jun porcelain rose violet glaze. The Jun porcelain rose violet glaze is prepared from the following raw materials in parts by weight: 38 to 46 parts of feldspar, 17 to 23 parts of quartz, 6 to 10 parts of talc, 12 to 18 parts of calcite, 2.5 to 3.5 parts of Suzhou soil, 4 to 6 parts of soda lime, 4 to 6 parts of copper ore, 0.8 to 1.2 parts of stannic oxide and 0.2 to 0.4part of blue powder. On the basis of the traditional Jun porcelain raw materials such as the feldspar, the quartz, the talc and the calcite, the Jun porcelain rose violet glaze provided by the invention adopts the copper ore to cooperate with the blue powder and the stannic oxide to serve as coloring agents, uses the soda lime and the Suzhou soil cooperatively, adopts heat preservation for 1 to 2hours in the firing later period, adopts a method of opening a kiln door to perform oxidation and cooling, and increases the firing finished product rate and saves the cost on the basis of maintainingthe characteristics of the rose violet glaze.

Description

technical field [0001] The invention belongs to the technical field of Jun porcelain production, and in particular relates to a Jun porcelain rose purple glaze and a preparation method thereof. Background technique [0002] Jun porcelain is a rare treasure in Chinese ceramics. It is famous for its colorful, simple and elegant style, and unique style. It occupies an extremely important position in the history of Chinese ceramics. Jun porcelain is expensive in the kiln. The beautiful opalescence of the glaze and the kiln change phenomenon are based on strict control of the chemical composition of the tire and glaze and the control of the firing process, so that the glaze produces liquid-liquid phase separation and the macroscopic distribution of phase-separated droplets. obtained from different rhyolite structures. [0003] Rose purple glaze is generally made of copper oxide as the coloring agent. The copper red glaze fired in a reducing atmosphere has a reddish purple color ...

AI Technical Summary

Problems solved by technology

[0003] Rose purple glaze is generally made of copper oxide as the coloring agent. The copper red glaze fired in a reducing atmosphere has a reddish purple color and a blue color in the purple color. Refer to Li Guosheng. Experiments on rose purple glaze [J] Ceramics, 1988 (03): 6-8, or use copper, iron, cobalt, manganese, zinc, etc. as coloring agents to fire, refer to Chen Kun and .Scientific Research on Copper Red Glaze - Starting from Jun Kiln 【J】Journal of Xuchang University, 2012 (06): 17-22. However, the above-mentioned firing methods all have certain defects, and chromium tin red is used as the colorant for firing The process and the fired products have certain pollution due to the presence of chromium ions. Using copper oxide as the colorant or using iron, cobalt, manganese, zinc and other elements as the colorant, the firing process is complicated and there are many influencing factors. , lower yield
