"The Jinling Museum has a jade artifact unearthed from the Qing Dynasty. It was plastered and made it shiny and moist. Experts estimate that this jade artifact has been played with for more than 60 years." As he spoke, Jiang Tongmao looked fascinated.

Jiang Tongmao likes jade and knows how to plate jade, and has also personally taken it. So he was shocked that the mountain could produce a piece of beautiful jade so quickly.

"Isn't this piece of jade the high imitations you bought?" At this time, Yu Shui had already thought of the origin of these jade ornaments.

Yu Shan nodded and said, "Yes, so this is not an ancient jade unearthed from the ancient tomb of the grasshopper, but a modern imitation I bought from a stall."

"You can imitate one for me? Can you imitate it or can someone else? If you find one, I will definitely not eat him." Yu Jiangmei stared at Yu Shan, very dissatisfied with his answer.

Yu Shan touched his head and said, "I don't really understand this thing, but it looks good. Can it become real?"

"Are you wrong about this? The carving skills of ancient jade can be easily imitated by modern people?" Yu Jiangmei said.

Yu Shan had already heard some clues at this time, and he said thoughtfully: "Isn't this a machine? I see that these edges are clear, but these are obvious machines."

Jiang Tongmao just thought that Yu Shan was a master and had a look of admiration. When he heard this, he looked contemptuous and almost spit on Yu Shan's face.

"Who told you that the lines are a little harder, is it a machine? Can your machine carve such negative lines? Whose machine can outline such vivid jade cow?" Jiang Tongmao said the louder and louder, which directly attracted the rest of the Yu family.

"What's wrong?" Yu Youlong was the first to run out when he heard his son-in-law's voice. The eldest daughter and the eldest son-in-law have always been his pride. Every time they come back, they are envied by countless people, so Yu Youlong is very concerned about his son-in-law.

It was also because Yu Youlong and his wife was bothered recently that Yu Jiangmei deliberately made things difficult for Yu Shan. It was because Yu Shan made a big splash and overwhelmed Yu Jiangmei and his wife that the lost Yu Youlong kept talking.

"It's okay, we're identifying jade, it'll be fine in a while." Yu Jiangmei didn't want to say much to her father.

As a literary and artistic young man, Yu Youlong also likes this!

Otherwise, how could he be so fond of his eldest son-in-law? It is because they have a common hobby.

"I know a little too! If you can't make sure, you can ask me!" Yu Youlong said shamelessly.

Here, Jiang Tongmao and Yu Jiangmei are both master's degree winners in history. Will they ask for a trick that will become a monk halfway?

Among the ten things that Yu Youlong collected, nine of them were fake and one was not real. At this level, I still ask for advice?

"I don't know anything else. A jade cow of this style was once unearthed in the Guo State Cemetery, and now it is collected in the Guo State Museum." Yu Jiangmeidao.

Jiang Tongmao also spoke, "This is green jade, ice-green. It was just locally exposed, and there were brown-yellow patches or spots. Now you have been stripped out, so you can see that the jade is delicate and slightly transparent.

You can see clearly that the single side here uses a tangle to outline the two horns, eyes, nose, shoulders, chest, neck and other parts of the cow. With such exquisite techniques, which machine can imitate it?"

Yu Shan was a little confused at this time. He took out this jade cow, and it was nothing special. He had many such jade decorations.

Now Yu Shan still has some jade pendants in his hand. The reason why he took out this jade cow was just because he gave it to the little girl, so he did not take out the ring or semi-circular simple jade ornament.

It happened to be the ox of Jianghua, so I gave it to her. I didn’t expect that this jade cow has such a origin.

"Is this not jasper? It's a piece of green jade? Can you two be sure of it?" Yu Shan was a little stunned. What is the difference between green jade and jade?

Jiang Tongmao was completely sure at this time that Yu Shan was just a stick and could not even be considered a rookie.

Yu Jiangmei's contempt was even stronger: "Are you a master?"

Yu Shan said embarrassedly: "Don't you have to be so exaggerated? I didn't have to press the title of master on my head. Besides, I'm not an appraisal master?"

"You have a self-knowledge and ignorant guy. Although the appearance of jasper and jasper are similar, they will be somewhat green, and they will coexist together at the same time, especially the jasper in Hotan, there is still a very obvious difference between the two.

The tremolite content of jasper is lower than that of qingyu. Jasper contains more yang rocks, and also contains a certain amount of chromium spinel, graphite dots, chlorite and pyroxene. The color of qingyu is uniform. Jasper has different minerals and has many colors, which is manifested as uneven color of jade. In addition to the yellow-green iron, it also contains chromium emerald green.

Green jade is obviously more blue-gray than jade. Jade is mostly green, dark green, dark green, green-black. One is produced in the contact zone that invades the rock mass, which is purer and more delicate. The other is produced in the contact zone that is superbasic rock mass. It often contains dot-shaped black mineral crystals, and its unique characteristics are.

Even if jasper is close to black, its thin sheets are still dark green under strong light. Currently, it is rare to use glass or plastic to pretend to be jasper. Generally, the common materials that vaguely jasper are black and green serpentine jade or dark green jade. Beautiful green is the best jasper. Such jasper, at a glance, uh? Is this jasper? How is it possible?”

As he was talking endlessly, Yu Jiangmei saw Yu Shan find a piece of jade pendant that is green all over. This jade pendant has some green blue and green, and it shines with a magical luster under the sunlight.

It was also facing the sun that Yu Jiangmei could see the particles inside the jade. The composition of the green jade was relatively single, the particles of the jade were relatively uniform and relatively delicate. The particles of the jade were much different in size, and usually the particles were larger in the thick color. So she recognized at a glance that this was a piece of jade huang made of jade.

"This thing is called Yuhuang?" Yu Shan's hand was an arc-shaped piece of jade, which was made of hollow carving. The carving was very fine. It was because of this fineness that Yu Shan took it out and prepared to give it to someone.

"It seems very similar to the jade lock. This is an evolutionary process. It should be an ancient jade passed down from the Qing Dynasty, so it is not surprising that jade appears." At this time, Jiang Tongmao spoke.

"The Qing Dynasty? No wonder the jade pendant in the Qing Dynasty gradually evolved into jade locks and jade plaques. This jade pendant should have been from the early Qing Dynasty. It seems that the jade pendant had begun to be mined at that time." Yu Jiangmei said.

Yu Shan knew that jade was mined on a large scale since the Qing Dynasty, but this jade pendant was not also authentic, right?

Yu Shan was a little amused and crying. Although he didn't know if it was really as Yu Jiangmei said, these carving skills were very good, he knew that when he bought these jade artifacts, he did not have the sadness of history at all.

And where does the color secretion above come from now?

Of course, Yushan was buried underground and raised. As for why he raised Sepi in such a short time, Yushan could only push him to the spiritual acupoint.

Seeing Yu Shan’s confused appearance, Yu Jiangmei thought that Yu Shan didn’t even recognize Yu Huang. “Huan is a curved piece of jade artifact, and the best half of the jade described in the article is Huang.”

Jiang Tongmao also explained: "In fact, the ancient jade huang was not limited to the regular half-bi and semi-circular shape. Huang was used as a ritual vessel among the six instruments. Zhou Lichun official Dazong Bo passed the Xuanhuang to ritual the north.

However, in archaeological excavations, it is mostly found on people's chest and abdomen, and it is often the wearer in jade pendants. Data shows that, except for the arc-shaped characteristics of jade pendants, the shape of jade pendants of various eras has a very large change, and only a few are regular half-bi shapes."

"In other words, this thing is more precious?" Yu Shan picked up the jade pendant in his hand in confusion. It seemed that even if these jade ornaments were all imitations, the imitation guy was also a master.

Yu Jiangmei immediately said with her eyes lit up: "Of course it is very precious and has great research value. Huang is one of the oldest jade shapes in my country. As early as the early Neolithic period, 7,000 years ago, jade Huang was found in Hemudu culture.

In the middle of the Neolithic Neolithic period, the Liangzhu culture in the Yangtze River Basin began, and jade pendants were widely manufactured and used. During this period, jade pendants were used as decorations for people to wear on their chests. The shapes were irregular and the changes were many.

During the Shang and Western Zhou dynasties, jade pendants were still widely used. Judging from the actual situation of archaeological excavations today, most jade pendants were still used as typical decorations at this time. The use of ritual vessels of Huang still needs to be studied in the future.

During the Spring and Autumn Period and the Warring States Period, jade pendants were popular. Jade pendants appeared in large numbers as part of group jade pendants. Their forms and patterns were extremely rich, and many alien-shaped pendants appeared. After the Han Dynasty, jade pendants declined.

The jade pendants of the Southern Dynasties and Northern Qi were both arc-shaped and plain, with holes drilled at the outer periphery. Some were also covered with gold edges on the inner and outer periphery, which was slightly different from the previous one. During the Southern and Northern Dynasties, jade clothes were hung with jade, and jade pendants reappeared. At this time, jade pendants had evolved into comb-back shape or diamond-shaped shape, which was different from the previous dynasties. During this period, jade pendants were very popular in society, so the number of jade pendants was very small.

Aristocratic women in the Tang Dynasty liked to wear jade in groups. The main body of the jade was a cloud-shaped jade pendant, which was the same as during the Southern and Northern Dynasties. Jade pendant was quite rare at that time. From the Song Dynasty to the Ming and Qing Dynasties, there were many small jade pendants in pseudo-ancient jades, and their purpose was nothing more than to enjoy and collect. What people wear in daily life has evolved into new forms such as jade locks and jade plaques."

Yu Shan understood that there were quite a few such things before the Han Dynasty, but after the Han Dynasty, the number was very rare, so no matter which era it was, it was considered a rare thing.

Yu Shan shook his head: "What a pity! This jade pendant cannot be authentic."

Yu Jiangmei looked at the brand new jade jade pendant and was a little confused, saying, "Yuhuang is a country's important weapon. I heard that it was a magic weapon used by wizards at that time. Logically, each item should be very precious and cannot be passed down at will. Could it be that this piece was just produced by you?" To be continued^
