Jade knowledge

A piece of jade is placed in front of you, maybe you wouldn't associate it with a fine jade, because the raw jade is not much different from ordinary stones and pebbles. At that time, the Chu people were so kind and dedicated to the jade, because the average person could not understand, suffered the crime of deceiving the king, and was taken away.

The causes and processes of jade material are not much different from ordinary stones and iron ore, but the mining situation is different. This is due to the different forms of jade mines that exist in nature.

What kind of jade is a good jade? This question is difficult to answer, because the meaning of jade is inherently wide. Xu Shen said: "Jade, the beauty of the stone." Therefore, in general, naturally generated, after processing can become fine and smooth, bright colors, tough texture, stable chemical properties, can be said in the jade .

We usually say that jade is mainly based on nephrite and jadeite. Nephrite refers to the jade which consists of tremolite-yangshi stone minerals, namely white jade, sapphire, jasper, topaz, etc. The jadeite is the emerald from Myanmar that is close to the nephrite trait. Diamonds, red sapphires, agates, crystals, etc., are mostly single crystal structural minerals, which belong to gemstones in a narrow sense; ivory, coral, coal crystals, tortoise shells and the like are attributed to "organic gemstones". The requirements for soft and hard jade are relatively consistent, that is, the texture is hard and compact, and the color is bright and beautiful.

However, jade culture is indeed a special culture of China's profound esoteric. She is indeed full of China's entire historical period. Her anecdotes about her are rich and colorful, and they are dizzying.

There are many Chinese words from jade, "ball, Lin, 琅, ring..." about five hundred, people describe the good things, but also add a jade word. Such as jade girl, jade hand, Yu Rong, jade appearance, jade, jade sound, jade food ... even if it is a sacrifice for justice or shackles, it is also described as "Jade". In the ancient Chinese literary biography, there is no shortage of stories about the jade, the horror and the tears.

Although jade culture has been discovered in other regions and countries, it has been a long-lasting experience like China, from the early 10,000-year-old primitive lag, slash-and-burn, ruined blood, barbaric era, the early Neolithic era, to today's developed electronics and space era. With the phenomenon that the Chinese nation has gone through the entire historical period, it is only seen in the world. Moreover, the connotation of Chinese jade culture is rich and profound, and the degree of personification and mystification is incredible.

The jade articles of the Neolithic Age in China generally believe that the earliest materials can be found in the site of the Xiancheng Cave in Haicheng, Liaoning Province, which is 12,000 years old. It is a stoneware of serpentine texture. Later, there were more than 7,000 years of the Hemudu site in Zhejiang. About six years ago, the lower part of the Shanghai Zhangze site, the earrings of Majiatun culture. The jade and jade rings found in the middle tomb of the Zhangze site more than 5,000 years ago. The jade in the early stage of this stage and the fairy hole may be accompanied by stone due to the scarcity of materials, and the rough making process drowns the advantages of fine and glamorous, and once it can only be used as a production tool. With the invention of the grinding technology, people finally discovered regularly that there are still a number of materials in the stone that are exposed to be particularly fine and glamorous. Although people do not know it as jade, it has been deliberately selected for the decoration of the human body. The phenomenon that the Zeze people contained jade in the mouth even showed that the ancestors had produced an indescribable mysterious thought on the jade.

For those who like jade, the most fearful thing is the fake, which is what we usually call fakes.

The identification of glass imitations on the market is probably the most common and simplest of the products. Common is a group of small rings, chicken hearts, and jade tablets that are called jadeite. Because the glass product is molded, the high temperature glass liquid will overflow a little at the edge of the object, and become a faint convex line after cooling. Touched by hand and seen by the naked eye will be discovered. If there is a magnifying glass on hand, it will be reflected in the light, and there will be large and small bubbles.
