Problems solved by technology

[0005] In today's environmental protection situation, the firing of liquefied gas kiln has become the mainstream of Shenhou Jun porcelain, but the disadvantage of liquefaction is that the temperature rises too fast. The fire can be ceased within an hour, which results in a short firing time and a general kiln transformation effect.

Abstract

The invention relates to a burning process of blue-gray jun porcelain. The burning process comprises the following steps: (1) preparation of a blank and glaze; (2) preforming; (3) biscuiting; (4) glazing; (5) glaze firing. According to the burning process, a liquefied gas kiln is adopted for burning; in the early stage of ignition, the pressure is reduced to 0.03 at first, and then the liquefied gas kiln is ignited, so as to facilitate drying of a blank; the pressure is increased to 0.12 during heating; the temperature of 1,250 DEG C is maintained for 2 to 3 hours, which is favorable for closing of a glaze surface and enhancing the glossiness of a product; the furnace transmutation effect is better; the glaze surface is as moderate as jade.

Description

technical field [0001] The invention relates to the field of firing Jun porcelain, in particular to a firing process of gray blue Jun porcelain. Background technique [0002] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics has unique significance. Different dynasties and dynasties in Chinese history have different artistic styles and different technical characteristics. "china" in English means both China and ceramics, which clearly shows that China is the "hometown of ceramics". As early as more than a thousand years before the Europeans mastered the porcelain manufacturing technology, the Han people had already produced very exquisite ceramics. China is one of the first countries in the world to use pottery, and Chinese porcelain is highly...
