In the Qing Dynasty, Gong praised blue-and-white porcelain in his Tao Ge: "White glazed blue-and-white porcelain is fired, and the flowers are bright from the glaze. You can participate in innate beauty, and infinity comes from Tai Chi. " Modeling: simple and heavy, elegant and dignified, simple and generous, with smooth lines, which embodies the sublimity and conventions of ancient courts, reveals the implicit beauty of a fresh and sophisticated nation, and contains the profound philosophy of "harmony between man and nature". Jun Porcelain: Pattern: "Burn white tires, rainbow comes, colorless kiln opens." The poems of the ancients praised the beauty of the patterns of Jun porcelain. Jun porcelain glaze, in the high-temperature firing, the glaze color blends and changes naturally, forming a variety of graphics, just like freehand brushwork in Chinese painting art, with both form and spirit, like reality and illusion, and endless artistic conception. Glaze color: Glaze color varies from kiln to kiln. The most famous ones are: vermilion, chicken blood red, tomato skin purple, grape purple, azure, moonlight white, peacock green, sapphire blue, fireworks and so on, which can be described as colorful. Sometimes a variety of colors are combined, "red is purple, purple is deep blue, green is white, white is red", and sometimes pearl spots appear. Therefore, there is a saying that "the painter is clumsy and the painter is difficult to paint". Moreover, "the kiln is unparalleled and Jun porcelain is unparalleled", and there will never be two pieces of Jun porcelain with exactly the same glaze color. The picturesque effect of kiln has long been praised by literati. For example, "painters are clumsy and don't paint, poets complain that their words are poor and don't paint", "the evening mist is light and Chi Jing, and the setting sun is faint and flowing", "the sky is full of smoke, and the sunset glow is purple." Texture: Jun porcelain is fired by a unique process, and various patterns are formed on the colorful glaze, such as: borneol pattern, which seems to be hammered without trace; Worm pattern, dragon walking in the snake; Fish egg pattern, stars. In addition, there are rabbit silk patterns, crab claw marks and rain silk patterns. Especially with aesthetic value is the ice crack, commonly known as "opening". Cross-cutting, such as network distribution, always uses large equipment to open small pieces, and it is better to open large pieces with small equipment. This grain is naturally formed because of the different cold and hot shrinkage rates of fetal quality and glaze. Ice cracks are caused by cracking after firing, not hidden in the glaze when firing. Therefore, in the process of opening the film, cracking will occur. While enjoying the wonderful phenomenon of "breaking through glaciers and fishing in shallow nets", listening to the brisk and crackling sound of the opening film is really a rare aesthetic conception. Blue-and-white porcelain of different dynasties in China has its own characteristics.
