Qingbai Porcelain Making Technique (Fourth Batch Provincial Level) In the Song Dynasty, the innovative Jingdezhen porcelain workers emerged as a new force and created a new type of porcelain, Qingbai porcelain, which influenced the whole country and the world. "Chinese Ceramics History" records: "Qingbai porcelain is a kind of porcelain with a unique style fired by Jingdezhen kilns in the Song Dynasty. Because its glaze color is between blue and white, with white in blue and blue in white, it is called Qingbai porcelain, and is generally called "shadow blue". "Archaeological discoveries show that the Song Dynasty porcelain kiln sites where Qingbai porcelain was fired in Jingdezhen include Hutian, Xianghu, Shengmei Pavilion, Nanshi Street, Huangnitou, Liujiawan and many other places. Among them, the scope of the Hutian kiln site is as large as 400,000 square meters. The site has kilns and a large number of kiln tools, and porcelain fragments remain, which can imagine the grand occasion of firing Qingbai porcelain at that time. The varieties and carved, scratched and printed patterns of Qingbai porcelain in the Song Dynasty are rich and varied. The production techniques of traditional blue-and-white porcelain mainly include four aspects: porcelain clay selection and processing techniques, porcelain glaze processing and preparation techniques, blank body decoration processing techniques, and porcelain firing techniques. Blue-and-white porcelain has a prominent position and outstanding value in the history of Chinese ceramics: blue-and-white porcelain represents the level of porcelain firing in the Song Dynasty, and the blue-and-white porcelain system ranks first among the six major porcelain systems in the Song Dynasty. Blue-and-white porcelain products have a wide influence on the whole country and the world.
