Ye Yu's words shocked the two of them.

One is Jin Yuliang, he was worried that if one or two fakes really appeared, and if they were discovered, his previous public relations strategy would be completely abolished and he needed to re-publicize, but he didn't expect Ye Yu to say that ten were fakes.

Ten pieces have been admired by many people, inspected by the Customs and Cultural Relics Bureau, and endorsed by one of the most prestigious local seniors, in this case, is it possible?

When pigs fly.

At this moment, the heart he was holding before was a lot more relaxed, but he always felt that something was wrong.

Maybe it's because the shock that Ye Yu gave him by exposing the Xuande furnace before has not disappeared, but this time, he really thinks that Ye Yu is a person who deliberately looks for something to talk big.

Another shock was Park Ki-shang.

But he is different from Jin Yuliang, he just didn't expect Ye Yu to dare to say that his ten collections are fake, he was stunned for a while, and the whole audience was discussing, so they didn't speak.

The movement at the door was quite big, Hou Chao asked Zhang Dongliang to maintain order, but he didn't let the company's people disband, and the next thing was the key.

This will make even Hou Chao extremely nervous in his heart.

All his confidence comes from Ye Yu, if Ye Yu can't tell the evidence of the fake, he will be unlucky this time, as for whether the things on the stage are real or fake, Hou Chao can't see it at all.

"Please be quiet!" Ye Yu stretched out his hand and pressed it down.

At this time, the auction hall seemed to be his home field, and the auctioneer of Thang Long Company next to him was a little overwhelmed, dazed and panicked.

Ye Yu's words made the venue quickly become quiet, and the new customers who came to him in the evening looked at him suspiciously, not because they didn't believe his words, but because his words really couldn't be believed.

However, the few people who participated in the auction in the afternoon and stayed to participate in the evening auction had a little expectation in their eyes.

The Xuande furnace in the afternoon was seen through by Ye Yuhuo's eyes, who knows if these ten pieces will be the same?

If that's the case, then it's not in vain today, such a big bustle can be seen with your own eyes, enough for them to blow for several years.

"Since I said that these are all fake, naturally there is evidence, and then I will take out the evidence and tell you one by one!"

Ten auction items were still on the stage, and Ye Yu first walked to the last auction item, which was also the treasure that the auction item intended to finale, Gao Bing Yellow Yang Green Bracelet.

This jadeite, among the ten auction items, is the easiest to see.

"This bracelet, first of all, is not a natural jadeite, it is a chemically pickled, artificially colored jadeite, belonging to class C jadeite, or called B + C jadeite!"

Ye Yu pointed to the jadeite hand in the glass cabinet and talked eloquently, you can't completely say that this bracelet is not jadeite, after all, whether it is grade B or C, its raw material is still jadeite jade, but it has been chemically processed, not natural jadeite.

Originally, the value of jadeite was very low, and after processing, it can be made into high-end jadeite, passing off as natural jadeite.

But the general B and C-grade jadeite, after making it, is not very clever, let alone experts, even senior players can see it, not to mention others, just a few subordinates of Ye Yu's jade department, all of them can be identified.

This kind of jadeite is basically to deceive people who have just entered the industry, or who don't know how to pretend to understand.

However, this one not only uses chemical means, but also has a clever fraud technique, not to mention senior players, even experts will be beaten.

"Ridiculous!" Jin Yuliang rebuked loudly, and Ye Yu's reason lowered the worry in his heart again.

Ye Yu actually said that this bracelet is made of C-class jadeite? How is this possible, the counterfeiting of jadeite is still different from antiques, it is really C-class, and it is impossible for so many people in front of it not to see it.

"Mr. Jin, since you think it's ridiculous, do you dare to do an acid test?"

Ye Yu looked at Jin Yuliang with a smile, the method of identifying chemical jadeite is very simple, that is, to do a chemical test, because whether chemical jadeite is pickled or colored, the pH value of normal jadeite is different.

However, the acid test has a drawback, it is easy to cause damage to the surface of the jadeite, and the jadeite jewelry that has usually done this kind of detection must be extremely careful and must be treated correctly to avoid hurting the jadeite.

If it weren't for the fact that this method was the easiest and fastest, and Ye Yu knew that this was a fake in itself, he would not have made this suggestion.

Kim Yuliang hesitated a little and looked at Park Ki-shu.

After all, the thing belongs to Park Ki-book, and it does not belong to him, so whether he can do such a test or not, it is still Park Ki-shu who has the final say.

"Mr. Jin, since someone has questioned your auction items, it is still appropriate to do a test!"

"That's it, Mr. Jin, we support testing!"

"Mr. Park, you also want to clear your baby's grievances, right?"

Many customers at the scene took the initiative to persuade Jin Yuliang and Park Kishu, these are all customers who plan to bid for this high ice yellow yang green bracelet, Ye Yu's words made them mutter.

It is better to believe that there is something than to believe that it is not, this is the kind of thinking of the Chinese people, since they have doubts, they want to know the final answer.

"Yes, I agree to the test, but if the test doesn't get any results, you have to give me an explanation!"

Park Ki-shu agreed, he had absolute confidence in his own things, this jade bracelet could not be Class C at all, he bought the gambling stone raw materials and cut them before processing.

He will only think that Ye Yu is a clown.

He was still thinking about what kind of compensation he should ask for against Ye Yu or Ye Yu's company if he couldn't get the test results? He was a foreigner, and no matter how reasonable he was, he was not afraid of making trouble at all, and if it was a big one, it would be an international dispute.

When Park Ki-shu thought about this, Kim Yuliang had already asked people to get tools to test.

Before testing, he and Zhao Min from the jade department carefully looked at the jade bracelet in the glass cabinet again.

Zhao Min assured him that the bracelet was completely fine, and that it did not have any characteristics of Class B or Class C jadeite at all.

As long as it is chemically processed, there will inevitably be traces inside the jadeite, such as small potholes, or opaque, low refractive index and other problems, which is why senior players can identify whether it is a natural jadeite.

This jade bracelet, no matter how you look at it, will not be Class B or C, Zhao Min has great confidence at this time.

Soon, the employees of Shenglong sent all the testing tools, and sent a small acid detector, which was not their company, but a neighbor in their office building was a testing agency, and Jin Yuliang specially asked someone to borrow this kind of tool.

There must be no mistakes in this test, and he can't rest assured of ordinary test strips, so he borrowed more professional tools.

Zhao Min personally went to inspect it, and the bracelet was carefully taken to the table by him, and there was a large screen at the auction site, which was originally used to display the auction items, but it was used as a temporary live broadcast screen at this time, so that all customers on the scene could see it more clearly and carefully.

The acid test, which is really very simple, is not very common.

Normal jadeite is weakly alkaline, but the quality of jadeite that can be pickled has been changed, and pickling can be soaked in acid-alkali solution for a long time, even for more than a month, and it is impossible to maintain the original natural weak alkalinity.

Zhao Min is extremely careful, jadeite is a delicate thing, and it can't touch acid or alkali, so Zhao Min has to get started in person and can't hand it over to others.

In the entire Thang Long auction, he is the most experienced in jade.

The simple test was completed in Zhao Min's hands, and then Zhao Min wiped his sweat and breathed a sigh of relief, not realizing that the atmosphere in the audience had completely changed.

The instrument they borrowed could directly display the acidic value, and the value was already displayed on the instrument at this time.

3.7。

This value, it is obviously abnormal, the real jadeite is weakly alkaline, not lower than 7, what does it mean to come out with a 3.7?

Even if you don't understand, you will see that something is wrong, the acidity value is so low, it is obviously not something that normal jadeite can have.

"Impossible!"

Park Ki-shu was the first to stand up, his face full of disbelief, and Kim Yuliang was completely stunned, and Zhao Min only found out about the value he detected.

Ye Yu smiled slightly, the general class B jadeite is soaked in strong acid, and then continued to soak with strong alkali, the pH value will be abnormal, but it will not be so low.

The counterfeiting of this jade bracelet only went through strong acid, but not strong alkali, and then used other counterfeiting methods to make this bracelet more deceptive, almost fake and real.

Don't ask Ye Yu how he saw it, he got the inheritance of the thirteen tricks of jade inspection, and he could recognize it at a glance no matter how fake it was, it was really perverted.

"Did you do something?" Park Kishu suddenly pointed at Ye Yu, his face flushed, and he was very excited.

"From beginning to end, I haven't touched jadeite, fortunately there is monitoring here, otherwise I can't wash it by jumping into the Yellow River, everyone says right?"

Ye Yu looked at the audience, hundreds of customers who participated in the auction agreed, Ye Yu did say that the bracelet was fake, but it was also a fact that he had never touched the bracelet, this was what happened under everyone's noses.

Only then did Park Ki-shu remember that the person he had just identified belonged to Thang Long Company.

"Mr. Park, don't worry, what is fake is fake, it can't be true, I still have a way to make it show its original form, it's up to you to dare?"

Ye Yu's voice was a little louder, Hou Chao was already laughing, and Ye Yu really didn't disappoint him.

The customers in the audience, this will also support Ye Yu more, the preview of Park Kishu's previous exhibition was too arrogant, what to say about this and that leak, and the attitude of seeing no one in China is really unpleasant.

This will turn his so-called leakage into a fake, and there are really a lot of people who gloat, and they all follow the coaxing at this time.

"What's the solution?" asked Park Ki-shu, gritting his teeth.

"Alkali washing, this fast jadeite counterfeiting method can be called a must, but no matter how powerful the fake, there is a way to make it appear, as long as it is washed with alkali, even if it is a weak alkali, you can see its true appearance!"

The fraud of this piece of jadeite is really powerful, and its biggest nemesis is alkali, because it has not been soaked in alkali before, as long as it is washed with alkali, it can show its true appearance.

Ye Yu didn't know why he knew so much, anyway, after taking a look, he could understand without his extreme eyes that all of these came from the inheritance of the thirteen moves of jade inspection.
