Xing kiln ceramic firing technique, a traditional technique of Neiqiu County, Xingtai City, Hebei Province, is one of the national intangible cultural heritages. Xing kiln is one of the seven famous kilns in China's Tang Dynasty. Xing kiln began in the Northern Dynasties, flourished in the Tang Dynasty, and declined in the Five Dynasties. It has been fired for about 800 years and has a history of more than 1,500 years. Xing kiln became a famous kiln in the Tang Dynasty for its rich product variety, solid and delicate body, and exquisite decorative techniques. The body of Xing kiln white porcelain is hard and thin, the sound is crisp and pleasant when knocked, the glaze is smooth, the glaze is white, clean and slightly flashes blue-gray or light yellow, and it is known as "silver-like" and "snow-like". Its product types involve all areas of people's lives, so "there is no noble or humble in the world". In the Paleolithic Age, humans have lived and multiplied on the land of Neiqiu. In the Neolithic Age, our ancestors were able to fire exquisite pottery. It has a history of nearly 7,000 years and is one of the birthplaces of Chinese pottery production. Xing kiln is an early kiln for firing white porcelain. As early as the Northern Dynasties, in order to increase the whiteness of the products, the kiln workers of Xing Kiln applied the technique of applying cosmetic soil to protect the body, which was a major innovation of Xing Kiln in porcelain production. The first use of the sagger firing method to further improve the quality of the products was also a major contribution of Xing Kiln in porcelain production. It had a positive impact on the future porcelain industry and has a high research value. The Xing Kiln successfully fired the transparent white porcelain in the Sui Dynasty. Transparent white porcelain is an artistic treasure among the white porcelains of Xing Kiln. The body and glaze are not only delicate and white, but also exquisite and transparent. This discovery fills the gap in the history of Chinese ceramics. In the Sui Dynasty, high-end white porcelain with exquisite shapes and strong transparent performance was fired. Porcelain making began in the Northern Dynasties. After the development of the Sui Dynasty, the area around Neiqiu County in the Tang Dynasty was a porcelain capital with many kilns and a rich production of fine white porcelain. It became a representative kiln for the production of white porcelain in China, and was named because Neiqiu was located in Xingzhou. Xing Kiln became one of the seven famous kilns in the Tang Dynasty for its rich product variety, solid and delicate body, and exquisite decorative techniques. Its product categories cover all areas of people's lives. In addition to paying tribute to the court, it is also exported to more than a dozen countries and regions overseas, achieving the goal of "being used by everyone in the world regardless of status". In the Song Dynasty, a small amount of tribute was produced, and its porcelain production scale could not be compared with that of the Tang Dynasty, so it gradually lost its competitiveness and gradually disappeared in the long river of history. The shape and decorative patterns of Xing kiln products will change according to the purpose and sales target, which shows that Xing kiln craftsmen can design products to adapt to the spiritual pursuits of people from all walks of life. Fine white porcelain products are exquisitely made, plump, smart and elegant, and have complicated decorative patterns. The works look noble and gorgeous, which just caters to the aesthetics of the upper class. Coarse porcelain is mostly folk supplies. Generally, the shape is relatively large and heavy, the shape is rough and generous, the decorative patterns are concise and smooth, and it has a distinct folk style of simplicity. Xing kiln has the characteristics of producing white porcelain and firing yellow glaze porcelain, black glaze porcelain, sauce glaze porcelain and tri-color utensils. Xing kiln has the characteristics of rich products. Including production utensils, Buddhist utensils and funerary objects. The white porcelain utensils of Xing Kiln have the characteristics of round lips, short necks, full shoulders and bulging bellies. This kind of shape looks solemn and elegant. Xing Kiln ceramics have typical craftsmanship characteristics. In terms of decoration, there are early body decorations, Tang Dynasty carvings, printings, and colored glaze decorations, and realistic shapes of pottery and porcelain sculptures, all of which show the superb artistic charm of the kiln workers. After the Sui Dynasty, the secret of the transformation of celadon into white porcelain and the transformation of coarse white porcelain into fine white porcelain was found, thus the creation of fine white porcelain and transparent white porcelain appeared. In decorative art, it is generally believed that Xing Kiln is used to burn white porcelain. In fact, this is not the case. Since the Sui and Tang Dynasties, Xing Kiln has changed the previous conservative situation of plain surfaces, and has appeared a variety of decorative techniques such as stamping, decals, printing, carving, scratching, carving, hollowing, pinching, mold printing, tri-color, dotting, pottery, porcelain, etc. Yellow glazed porcelain, black glazed porcelain, and sauce glazed porcelain have come out one after another, presenting a glorious history of Xing porcelain. In terms of firing technology, since the founding of Xing Kiln in the Northern Dynasties, bowl-shaped vessels have been mainly stacked and fired upside down (stacked with the mouth upward, and each porcelain blank is separated by a triangular support nail). This firing technique was used for a long time in the Sui and Tang Dynasties. It is not difficult for kiln workers to find that there are many disadvantages in this way. The kiln is easy to fall during firing, the glaze flow is serious, the glaze sticks, and the triangular support nail marks are left in the vessel, which is not beautiful, there are many defective products, and it is not easy to sell. Kiln workers have continuously improved the firing technology. Since the middle Tang Dynasty, the stacking and covering firing method has gradually appeared (stacked with the mouth downward, and each porcelain blank is separated by a triangular support nail), which avoids the occurrence of previous problems and the product quality has also leaped forward. In 2014, the Xing Kiln Ceramic Firing Technique was approved by the State Council of the People's Republic of China to be included in the fourth batch of national intangible cultural heritage list, project number -213.
