The Origin of Jade Articles in China

China began to produce jade articles from primitive society, and with the development of social productive forces, it gradually formed an independent specialty, mostly concentrated in Guiji and Du Yi. From Song Dynasty to Qing Dynasty, Suzhou became the national jade manufacturing center. Jade workshops have been set up in the royal courts of past dynasties for production. Because of the high hardness of jade, special tools and methods are needed for processing, so the processing process generally includes several processes such as material selection, sample drawing, sawing, blank making, drilling, refining, polishing and carving. Ancient jade also needs to increase the processes of "disability" and "burning ancient jade". In slave society, bronze tools are the main tools for jade processing. Feudal society gradually changed from bronze tools to steel tools. The hardness of quartz sand is higher than that of jade, so it has been used to grind jade since ancient times, also called "jade-solving sand". When the toothless saw pushes back and forth or thallium and the drill bit rotate to contact the jade, quartz sand mixed with water is put in and grinded into a tool with the movement of the tool. The shapes and patterns of jade articles are made in this way. Therefore, it was called cutting jade in the pre-Qin dynasty, grinding jade in the Song dynasty, and now it is called grinding and cutting to show its difference from sculpture and craft.

The historical evolution of China jade art style is as follows:

.. in the south of China, the large jade bi of Liangzhu culture and the multi-section jade cong with different heights show that the jade processing technology has been separated from the stone technology. Jade modeling is more complex, and it has been able to polish the patterns of yin line, yang line, flat convex, hidden geometric shape and animal shape, with simple and naive style. Jade articles in Shang and Zhou Dynasties are characterized by simple image and outstanding performance, with double hooks in decorative details and pretty jade articles. During the Spring and Autumn Period and the Warring States Period, jade crafts developed extensively, and various vassal states competed to polish and improve them. Compared with the finely carved jade carvings in the Spring and Autumn Period and the Warring States Period, the jade carvings in the Qin and Han Dynasties tend to be bold and unconstrained in artistic style. The hidden place of Han jade is often engraved with subtle yinxian, which is as strong as wandering in ancient paintings to make up for its weak three-dimensional sense. This is a characteristic of jade techniques in Han dynasty, which has a far-reaching influence on jade in later generations. Jade articles in Tang and Song Dynasties are as bright as suet, with excellent texture and exquisite craftsmanship. The theme of animal flowers and exquisite utensils has increased, and the ability of realism has been greatly improved. They have begun to show the tendency of secularization and achieved high attainments in form and spirit. This is closely related to the maturity of painting and sculpture at that time. During the Yuan, Ming and Qing Dynasties, jade articles in the north and south developed generally, which was a very glorious era in the history of jade articles in China. The jade belt plate unearthed from Wang Xingzu's tomb in Ming Dynasty, the jade bowl, jade pot, jade cup, jade pot, jade Jue and Yu Pei unearthed from Zhu Yijun's tomb in Beihai and Yuanbao can represent the characteristics of jade articles in this period.

.. while inheriting the characteristics of jade articles in Song Dynasty, there are two mutually exclusive tendencies of extensive processing or tedious polishing. Jade articles in the Yuan and Ming Dynasties were also influenced by literati's calligraphy and painting. Jade articles that polished literati's poems and freehand landscape paintings were developed, and famous paintings were often carved to pursue literati's elegance. Jade in Qianlong period of Qing Dynasty reached an unprecedented peak because of its rich jade materials, royal advocacy and social needs. In addition, China * * * er's jade polishing technology is rich in local color, and it is an integral part of the jade art treasures of the Chinese nation. Under the influence of the trend of thought of archaizing in the late feudal society, all kinds of jades produced by imitating the style of "Hanyu" with the goal of "returning to simplicity" are called antique jades. This kind of jade began in the Song Dynasty and flourished in the Ming and Qing Dynasties. It has its special aesthetic value and is also an integral part of ancient jade.

Aesthetics of jade

The ancestors of China loved jade, not only because of its rare or beautiful appearance, but also because of its deeper aesthetic value: because jade condensed people's deep feelings-nostalgia for their hometown and worship of their ancestors. This feeling of homesickness and nostalgia for ancestors has cultivated the personality of the Chinese nation and nurtured China's traditional aesthetics. This beautiful tradition has lasted for thousands of years and has been emitting immortal glory.

Jade, as an ornament, as a token, as a vessel and as a gift, is practical and closely related to human beings. The beauty of jade comes from this, and ultimately from this.

"Returned to Zhao" is just the story of Lin Xiangru's mission to Qin State, praising the spirit of jade, the virtue of keeping promises and the sentiment of sacrificing one's life for righteousness.

.. "The jade is uncut and abrasive." This sentence has gone beyond reciting things and has become the motto of talents for a long time.

Jade collection

.. collect ancient jade, if the economic conditions are good and the strength is particularly strong, you can collect it according to the principle of careful carving and collection.

.. the collection of ancient jade should be based on fine workmanship, high quality, clever colors and strange shapes. Read more books and study more, and you can achieve the goal of "love is good."

The collection of ancient jade is generally divided into two categories: new jade and old jade.

The identification of new jade focuses on the authenticity of jade material, the quality of texture and the fineness of carver. Generally speaking, good jade material is only the basis for making jade articles, and its value can only be finally reflected through artificial design and carving. Emperor Taizong put it well: "Jade is beautiful, but it lies in the stone and is not worth pondering, just like rubble." Therefore, the level of jade workmanship is an important weight to determine the quality of jade. A good jade article should have exquisite and harmonious composition, exquisite workmanship and care for people who are warm and greasy.

In addition to the basic requirements of new jade, the identification of old jade should also identify the production time, historical role and the identity of the owner, and learn to comprehensively analyze the modeling characteristics of each object (including local modeling). The uniqueness of modeling can often affect the value of jade.
