Abstract

The invention discloses a Jianzhan firing process, comprising the steps of: providing green-body raw materials and a glaze slurry, conducting pugging on the green-body raw materials, conducting throwing shaping, and conducting trimming to obtain a green body; and putting the green body in an electric kiln for bisque firing, then conducting glazing, loading the glazed body in a sagger, sending thesagger into a chamber of a down draught kiln for sintering, conducting natural cooling, and taking the product out of the kiln. The formula, the firing atmosphere, the temperature curve and other technological flow are clear, easy to master and good in stability, the yield is high, the cost is low, prepared Jianzhan has less small pores, beautiful layered patterns, and a fine and moisture glaze surface, and can be favorably compared with Jianzhan produced through wood firing by a Dragon kiln.

Description

Technical field [0001] The invention relates to the technical field of porcelain, in particular to a Jianzhan firing process. Background technique [0002] Jianzhan is produced by Jian kiln. Jian kiln is one of the famous ancient kilns in my country. There are a large number of sites located in Jianyang District, Nanping City, Fujian Province (in ancient times, it was affiliated to Jianning Fu Ou Ning County). Its products have been famous in the Song Dynasty , Once sold overseas via the Maritime Silk Road. After the Song Dynasty, due to wars and other factors, Jianzhan firing skills were lost for hundreds of years. [0003] After the reform and opening up, the 800-year-old Jianzhan firing technique was restored and developed. On May 23, 2011, "Building Kiln and Building Burning Techniques" was included in the third batch of National Intangible Cultural Heritage Protection List. [0004] Since the development of Jianzhan in recent years, there are mainly two forms of production. On...
