Hetian jade is named after the origin and field and has undergone an evolutionary process. As early as the Neolithic Age, the ancestors of the Kunlun Mountains discovered Hetian jade and transported and communicated to the East and West as a treasure and friendship medium, forming the “Jade Road†of the oldest Hetian jade transportation channel in China. The predecessor of the "Silk Road". In the Warring States period, Hetian jade was known as the "Jade of Yu." The Qin Dynasty is also known as the "Jade of Kunshan", and later called "Yutian Jade."
At the beginning of Qin Shihuang, China implemented the emperor system until the Qing Dynasty, and Hetian jade became emperor jade. The jade of the palace is mostly made of Hetian jade. In particular, the jade that symbolizes the imperial power is made of jade, the vast majority of which is Hetian jade, and the earliest jade that was discovered in the era of Hetian jade, which was discovered from the Yin Fortress. After the Spring and Autumn Period and the Warring States Period, Hetian jade gradually became the main jade material, all of which were collected materials.
Hetian jade origin
Hetian jade is distributed in Xinjiang Shache, Kashkuergan, Hetian-Yuyu, and the 1,500-kilometer north slope of Kunlun Mountain in Qiemo County. There are 9 production areas. Hetian jade's mineral composition is mainly composed of tremolite-yangshi stone, and contains trace minerals such as diopside, serpentine, graphite, magnet, etc., forming white, cyan, black, and other different colors. Most of them are monochromatic jade, a few have variegated colors, and the jade is translucent, which is greased after polishing. Hetian jade is born in a mountain rock with an altitude of 3,500 meters to 5,000 meters. After long-term differentiation and disintegration into pieces of varying sizes, they collapsed on the slopes and then washed into the river by rain. When the river in the autumn is dry, the jade block collected in the riverbed is called seed jade, and the mountain material is mined in the rock layer. The earliest jade articles of the era that have been discovered with Hetian jade are from the tomb of Yinxu Women. After the Spring and Autumn Period and the Warring States Period, Hetian jade became the main jade material, which was collected from the seed material. During the Qianlong period of the Qing Dynasty, the Dagu River was controlled by Yushan, and the jadeite material weighed more than 5,000 kilograms, which was collected from the Maitreya Mountain.
Jade value evaluation
The evaluation of the value of jade is a very complicated jade; this jade works mainly includes three aspects. First, the assessor must be familiar with the quality and value of the raw materials used to make the jade; the second is to correctly judge the design material level and manufacturing process and related expenses of the jade; the third is to be familiar with the history of Chinese jade culture and the historical value and artistic value of jade. ,Practical value. Only a comprehensive understanding of all aspects of jade can be used to evaluate jade.
China has a history of jade culture for tens of thousands of years, which has precipitated the rich jade culture connotation and formed the tradition of Chinese people worshiping jade, loving jade, playing jade and collecting jade. There are a large number of exquisite jade articles in various historical periods in China, which have left us with valuable wealth. The production of modern jade is more colorful, and there are a large number of fines in the variety and jade design.
As the saying goes, "Gold is valuable for priceless jade", we face a beautiful jade, scientific and accurate evaluation is a difficult jade, it is difficult to be in the characteristics of the jade itself. The characteristics of jade articles include: jade carvings are hand jade carvings. Because different artists, different equipment, and even jade articles processed by different artists at different times are different, it is difficult to find the exact same jade.
Jade articles are made of different jade materials. Because of the variety of jade materials, the value varies greatly; even the same type of jade material, the quality difference is also very large, will directly affect the value of jade.
Jade is a work of art. The jade works are carefully thought through and carefully designed. The jade itself contains the elements of art. The same raw materials are designed by different designers, and the value of their works will be very different.
The craftsmanship of jade is very different. Different regions, different jade factories and different artists; there are differences in the production process, even the same artist pays different amount of labor and methods used in the production process; it also affects the production process. Inferior, and directly affect the value of jade.
The difference in aesthetics will also directly affect the value of jade. Different eras, different regions, and different nationalities have different aesthetics about jade, which will directly affect the value of jade.
Optical grade silicon with a resistivity 10-40 ohm-cm higher than that of most semiconductor applications.For cZ-grade silicon (Czochralski method), the absorption bandwidth is 9 m, which is acceptable for 3 to 5 m tropical applications.Floating zone silicon, on the other hand, has no such absorbency.
