The golden scale is not a thing in the pool, and it turns into a dragon when it encounters a storm. Coal jade and coal and coal gangue are buried deep in the ground, and one day they will be dug up, and coal gangue can only be used to pave the way, but coal can be used as fuel, and coal jade is directly carried to the high hall and becomes a treasure. Coal jade, also known as coal essence, belongs to black organic gemstones. Although these three are from the same origin, their values are vastly different. The most famous coal jade relics on the mainland are the seal of DuGuxin, which is currently one of the treasures of the Town Museum of the Shaanxi History Museum.
The multi-faceted seal of the LoneLy Letter
Speaking of this seal of lonely letters, there is also a bizarre experience. The story also began on November 9, 1981, when a middle school student named Song Qing in Xunyang, Shaanxi Province, saw a dark thing in the mound on the side of the road on his way home from school. He picked it up and wiped off the dirt on it, and when he saw that there were many faces, the size of a large mahjong dice, he put it in his bag and took it out to play with.

Later, he was seen by the teacher during the play, and intuitively the teacher felt that this should be an old object, so he asked him to hand it over to the Xunyang County Cultural Center. At that time, the staff of the cultural center took a cursory look at it, thinking that it was a black coal ball, and the child himself used a knife to randomly carve a few words, then reprimanded Song Qing, and casually threw this inconspicuous "small coal ball" on the shelf, and Xiao Song Qing had to leave sadly.

In 1990, an archaeologist surnamed Wang from the province came to the Xunyang Cultural Center to communicate, and when he was idle, he accidentally found this "small briquette" on the shelf. Elder Wang took it to his hand and carefully identified it, and shouted excitedly, this national treasure is actually here. Later, after being identified by several experts from the Shaanxi Provincial Museum, this small "coal ball" is the multi-faceted seal of coal essence of the "most cattle father-in-law" in the history of the mainland, and has since been included in the Shaanxi Museum and has become one of the treasures of the town museum.
When it comes to Dugu Xin, this person is very promising, because he was once the head of the Three Dynasties and was known as the "most cattle father-in-law". Dugu Xin, formerly known as Du Lonely As desired, was a Member of the Xianbei People, a Western Wei person during the Southern and Northern Dynasties. His eldest daughter married Yuwen Yu, the Emperor of the Northern Zhou Dynasty, and was the empress dowager of Zhou Ming. The fourth daughter married Li Xun, the father of Li Yuan, the founding emperor of the Tang Dynasty, and eventually became the empress dowager. The seventh daughter was married to Yang Jian, the founding emperor of the Sui Dynasty, who was also the queen of Sui literature. If you think about it, how prominent is the identity of such a person who is the head of the two dynasties and the head of the state of the taishang. The most crucial thing is that he has several positions, and in order to facilitate the order, he let people engrave his twenty-six identities on a polyhedral coal seal.
Part of the contents of the seal
And the material for making this seal is coal essence, so what is coal essence? As the name suggests, coal essence is the essence of coal, and the jianghu people call it black gemstone, also known as coal jade. With bright asphalt and glass luster, it was formed roughly 1800 million years ago, and the main production area on the mainland is Fushun. Coal concentrate is divided into two types, one is a density of 1.4-1.6, the main component is C, which is lighter than ordinary coal. The other is relatively rare, the petrochemical is more thorough, the density is heavier than coal, roughly 2.5, its main component is not C, and the luster is better after carving.

The mohs hardness of the coal essence is 2.5-4.0, the refractive index is 1.66, it is opaque, it does not dye the hands, and it will leave dark chocolate traces when sliding on the white paper, while other coal essence imitations will leave black or white traces. Because the coal essence will be static after rubbing, this is the same as amber, so some people call it black amber. The coal is fine in texture, has good toughness, and the port is shell-shaped.

Coal refiner is produced in many parts of the world and has been used for a long time. Coal refining products have been found in the European Stone Age and the remains of the North American Indians, and in the ancient Roman period, coal refining was a popular "black gem". In the middle of the 19th century, Prince Albert died, and Queen Victoria, grief-stricken, ordered the people of the country to wear only suitable for mourning for 20 years, so coal fine jewelry became popular.

The earliest coal refined products found in the mainland come from the Shenyang Xinle Cultural Site about 7,000 years ago, where the coal refined products are simple and simple, mostly bead-shaped or oval-shaped. In the lower cultural site of Xiajiadian in Chifeng, Inner Mongolia, 4000-3000 years ago, there are also many coal fine products, decorative items and exquisite animal and plant carvings.

Gangue is a solid waste found during coal mining and coal washing, which is a companion rock of coal, which is harder than coal and has an extremely low carbon content. Early gangue was generally used to pave roads, and now it is mostly used as a raw material for burning bricks or making cement. Compared to coal and coal concentrate, it has the lowest value. This is the same root, the value difference is thousands of miles. How similar are people and things, almost a little effort, almost a little opportunity, different origins, different times of appreciation, the results are very different, you say yes?
Heaven and earth people
At present, the price of natural coal essence large-scale carvings on the market is in the thousands, and some friends may say that there are more coal essence gadgets on the stalls, and it is only a few yuan and dozens of yuan. In fact, these gadgets are generally made of mixing pulverized coal and some kind of glue, not real natural coal refined products, I hope that friends can not be easily greedy and cheap. I am a stone idiot Keiko, carry forward the mainland jade stone culture, original is not easy, welcome to like and pay attention to forwarding.
