Jingdezhen is the representative and symbol of the "porcelain capital", with a long history of porcelain making and exquisite porcelain, which is world-renowned. Jingdezhen has a long history of producing porcelain. White porcelain as white as jade was burned in the Tang Dynasty, so it was called "fake jade". In Song Dynasty, Emperor Song Zhenzong gave Jingdezhen the title of Jingdezhen, so Jingdezhen was famous all over the world. After Yuan, Ming and Qing Dynasties, it became the national porcelain making center of "kiln gathering in the world". In the Qing, Kang, Yong and Gan dynasties, porcelain reached its peak in history. The profound accumulation of porcelain-making culture and skills for more than 2,000 years has established Jingdezhen's position as a world-recognized porcelain capital. Jingdezhen porcelain is "as white as jade, as thin as paper, as bright as a mirror, and as loud as a parallel". Especially, it is "as precious as a treasure, as bright as a mirror, and as beautiful as a book as Suzhou". They are all treasures of Chinese culture and art. During the Qianlong period, Jingdezhen porcelain kilns were numerous and widely distributed. In addition to official kilns, there are 200 or 300 folk kilns with tens of thousands of craftsmen. Blue-and-white porcelain wares produced in this period are clear and clean, with bright blue color, giving people a fresh and lively feeling. Multicolored porcelain is strong in color and magnificent, which is more developed than that of Ming Dynasty. The pastel porcelain created is soft in tone, distinct in layers and rich. Enamel-colored porcelain is inspired by western oil paintings on the porcelain embryo and then fired in a kiln. It is a special product of the court, blending Chinese and western. Among these colorful and precious porcelain, through various channels, along the "Silk Road" on the road, the "Ceramic Road" on the sea, and "traveling to nine places and spreading overseas", it has played a positive role in promoting China's cultural, artistic and economic exchanges and made great contributions to enriching and developing world culture. During the development of Song Dynasty, Jingdezhen porcelain was famous for its dexterity, elegance and beautiful shadow celadon. This kind of celadon (celadon) was successfully fired on the basis of firing celadon and white porcelain in the Five Dynasties. Celadon tires are exquisitely processed and have the reputation of "plain muscle jade bone". The glaze is white and blue, and it is as white as jade. In addition, the underglaze colored porcelain tire is also engraved with various exquisite patterns, which combine with each other and complement each other, forming a celadon with better color than Qiong Jiu. It is exquisite, beautiful, clear and elegant, and has become an extremely precious variety in the history of China ceramics, thus making Jingdezhen among the famous kilns in the Song Dynasty. Jingdezhen porcelain industry has been prosperous in Song Dynasty. According to archaeological findings, there were as many as 30 kiln sites in the Song Dynasty, including "more than 300 kiln sites", and the types of ceramics also developed to hundreds. In the Song Dynasty, Jingdezhen not only fired a wide variety of shadow glaze carved porcelain, but also successfully fired a large number of shadow glaze carved porcelain with different shapes and unique styles and copied a variety of glazed porcelain. Development of the Yuan Dynasty Jingdezhen in the Yuan Dynasty successfully fired blue-and-white porcelain and underglaze red porcelain, which are two very distinctive and valuable categories. Blue and white have strong coloring power, stable color, never fading patterns, elegant style, plain and beautiful appearance. Bright blue-and-white glaze and elegant white tire match each other skillfully, which has the characteristics of China ink painting and marks the arrival of a new era from plain porcelain to colored porcelain. With its multi-level, panoramic, distinctive decorative features and decorative techniques of painting-based, engraving, painting and printing, Yuan Blue and White has opened up a new road for the development of ceramic art in China. Red in the glaze is painted on the tire with copper red material, and the transparent glaze is fired in a high-temperature reducing atmosphere, which makes the porcelain with red patterns under the glaze difficult to fire and colorful, so that it is still an extremely precious porcelain category today. Red in glaze can be used to decorate porcelain alone or mixed with blue and white, which is called red in blue and white glaze. These two are extremely precious. The firing of high-temperature glass has also made outstanding achievements. Founded in 1278, the "Shufu" porcelain fired by Fuliang Porcelain Bureau is thick and opaque, and its color is white and slightly blue, just like the color of goose eggs (also known as "egg white glaze"). This white and moist egg white glaze is the basis for the emergence and development of blue-and-white and underglaze red porcelain, and also laid a certain foundation for the development of underglaze colored porcelain and "white" porcelain in the early Ming Dynasty. The appearance of other colored glazes, such as red glaze, blue glaze and gold glaze, indicates that people have mastered the rules of hair color of various colorants and made Jingdezhen porcelain decoration colorful, thus ending the situation that the glaze color of porcelain before Yuan Dynasty was mainly like jade and silver, and heralding the arrival of a new era. The development of the Ming dynasty in the Ming dynasty, Jingdezhen officials and people competed for the market. "There is a generation of porcelain that is the most exquisite and beautiful, all from Jingdezhen." "Several counties merged and lost to production in Rao Jun County, Jiangxi Province ... If four generations of China people are well-known hunters, they are all produced in Jingdezhen, Fuliang County, Rao Jun County." Jingdezhen has really become a place where porcelain kilns gather all over the world. In the Ming Dynasty, Jingdezhen not only inherited the technology of the previous generation and carried forward the types of firing, but also digested and absorbed the excellent skills of the declining famous kilns, extensively absorbed the essence of foreign culture, boldly innovated and created many new varieties, new shapes and new patterns, which really "created a generation of surprises". All these innovations not only created Jingdezhen's central position in the national porcelain industry in the Ming Dynasty, but also successfully fired fine porcelain in Yongle and Jingdezhen. Linglong porcelain is green and bright, and blue and white are elegant and attractive. The successful firing of Dalonggang and thin-shell porcelain is the embodiment of the high technical achievements of Jingdezhen porcelain industry and the amazing wisdom of porcelain technicians in the Ming Dynasty. Dalonggang, which is more than 70cm in diameter and height, is decorated with dragon whiskers with five claws. It is huge, magnificent and solemn, and it is dedicated to the emperor. Others should not use it illegally to further reveal its mystery. The production of thin-walled porcelain shows the artistic originality and intelligence of porcelain-making technicians from another side. The thinnest and thinnest thin-walled porcelain is only 0.5 mm thick, and the thickest is only 1mm, which is really "as thin as paper". Modern development of pastel rolling porcelain produced by Baocilin entered the new century, and Jingdezhen ceramics also experienced the transformation from the top ten state-owned porcelain factories to private enterprises. At present, the development of ceramics in Jingdezhen area has reached a new stage, with more and more ceramic enterprises and larger scale, forming a trend of "specialization in art". Some enterprises carry it forward in some difficult sintering processes, such as high-temperature glass and pastel rolling process. For example, Jingdezhen Jingdezhen Ceramic Co., Ltd. is such an enterprise that tries its best to promote the traditional culture of China ceramics. Through hard work, they finally realized the inheritance and development of high-temperature colored glaze, pastel rolling and other processes.
