Chen Xiu knew that Gu Dexin had the intention to study himself, and he didn't hesitate at the moment, and said directly: "The texture tremolite jade used in this dragon pattern jade pendant is also Hetian jade, and there is nothing wrong with it in terms of jade quality, this is also the jade used by Han jade;

But the biggest problem is the carving.

Everyone, please see, this dragon pattern was carved out in less than eight swords, which is also the famous Han Eight Swords......"

"I see!"

A bald old man said excitedly: "A few days ago, an expert told me that the jade carved by Han Badao was used for funeral purposes!"

Chen Xiu remembered this bald old man, Tang Ren had just introduced him as Wang Gong, and he said with a smile: "Elder Wang is right, the carving of the Han Eight Knife is generally used for funeral purposes. Judging from the color of the jade, it should be less than a hundred years old, and everyone looks at this piece of Qinxin......"

"Smack!"

That Wang Gong clapped his hands excitedly and said: "Even if such a big piece of Daqin Heart is invited to play with it 24 hours a day, it can't be raised so big in a hundred years." This is what experts call the historical contradiction, so there is a problem in judging this piece of Hanyu. ”

"Yes, Elder Wang, you are too right in your analysis. You must be a great accomplished in jade!"

This is to make Wang Gong very happy, although he is worth a lot of money in this group of people, but he is the latest to enter the collection sequence, so his collection skills are also the thinnest, usually in this group of rich people in the circle are the little brothers of the collection, the collection of things is not less Tang Ren, Ye Hongfei despised by the pat of Chen Xiu, is in a good mood, and even thinks: "It turns out that I have a talent for jade collection, but I can let me consider collecting jade for the collection think tank." ”

"That's right, this piece of Qinxin is indeed a fake. Gu Dexin said directly and frankly: "Brother Chen, you can't see what technology it uses to create a fake!"

At present, the most simple and crude fraud of Qinxin is to inject potions on the surface, such as injections with leaf oxalic acid, but this kind of counterfeiting has a disadvantage, that is, the formation of Qinxin will be black, from the perspective of this dragon pattern jade pendant, it is obviously not with this low-end method.

High-end counterfeiting is to speed up its formation through various modern catalytic means. For example, it is attached to iron and burned at low temperature, or it is put into a drum and rolled and dyed.

Ye Hongfei and Tang Ren also saw that this piece of Qin Xin was cheating, but it was good to see what kind of means were cheating, so the two of them even said strange things.

At this time, everyone looked at Chen Xiu with interest, to see if he knew the answer.

Chen Xiu smiled, he had the ancient jade hint of the counterfeiting technology of this jade pendant, and said with a smile: "The counterfeiting of this piece of dragon pattern jade pendant is actually very simple, using the basic principle of heat treatment and dyeing, and using the instantaneous high temperature to change the local structure of the material.

If my guess is correct, this is a natural gas spray gun, aimed at a point of the material, and the continuous heating, the part of the structure that rises in temperature will become loose. At this time, apply the pre-prepared potion, and you're done.

This heat treatment method is actually a new variant of the 'spot skin' technique.

Mr. Gu, I don't know if I'm right!"

As soon as his voice fell, Gu Dexin opened his mouth in surprise, you must know that in order to get this kind of counterfeiting technology, he bought it from a foreign laboratory specializing in ancient jade and jadeite.

This kind of technology is not known to anyone in China until now, because Ye Hongfei and Tang Ren know that this dragon pattern jade pendant is not the right version, and they can't see what the trick is. Unexpectedly, Chen Xiu saw through this kind of counterfeiting technique at a glance.

When everyone saw Gu Dexin's expression, they naturally knew that what Chen Xiu said was right, and they were also impressed by Chen Xiu.

At the beginning, Chen Xiu came in, and the reason why everyone was polite was because of Ye Hongfei and Tang Ren's elevation.

But the fact that a top rich man like them can be polite to you, but that doesn't mean they will respect you. If you want their respect, you have to show real skills.

And Chen Xiu can analyze the counterfeiting techniques that Ye Hongfei and Tang Ren can't see through, and he is definitely a rare talent in the treasure appreciation world!

"Smack, smack......"

Old Xu applauded and said to Chen Xiu: "Xiao Xiu, you shouldn't have learned this jade appreciation technique from Chai Hongquan." As far as I know, Chai Hongquan has a deep knowledge of porcelain restoration, but jade is not his specialty. ”

"I learned this piece of jade from Zhang Haishan and Zhang Lao of Anshan. ”

"I see. Zhang Haishan, this kid has learned a lot, but he can teach an apprentice like you!"

Hearing that Xu Hui actually knew Zhang Haishan, Chen Xiu couldn't help but be a little surprised, he originally thought that Zhang Haishan's reputation was only in Anshan, but he didn't expect that even Xu Lao knew him.

On this side, Wang Gong held the dragon pattern jade pendant and kept shining at the light, and muttered in his mouth: "What's special, I still want to collect jade in the future, I can't imagine that jade counterfeiting is so easy, and it can more than double its value with a musket." It seems that you still have to think carefully before you can make a move. ”

Chen Xiu said with a smile: "Elder Wang, in fact, the collection and investment of jade is still the most valuable, unlike the most technical and unpredictable counterfeiting of calligraphy and painting."

In fact, there are obvious flaws in this kind of jade that is counterfeited by heat treatment, but the new technology is not yet known. When everyone understands, they won't be able to fool anyone!"

As soon as Chen Xiu's words fell, everyone looked at them together, even Gu Dexin also wanted to know, although he spent a lot of money to buy this counterfeiting technology, but he didn't know where there would be a big flaw in this technology.

"Everyone, please see, like this piece of dragon pattern jade pendant was originally made by Hetian jade, but after high-temperature calcination, did you find anything different?"

Whether Chen Xiu turned on his mobile phone and flashed the light on the jade pendant, or did Ye Hongfei and Tang Ren see the difference first.

"This ...... There are broken lines in this jade!"

"That's right!"

Chen Xiu's middle finger clasped his thumb and flicked out, and his middle finger hit the dragon pattern jade pendant, and the jade pendant was broken into several petals at once.

"After the high temperature, the texture of the jade is actually destroyed, and it becomes as crisp as glass. ”

"I see!"

At this time, everyone realized in vain, Wang Gong directly handed over a business card to Chen Xiu, and said excitedly: "Brother Chen, a rare talent! We must communicate more in the future!"
