From the above, when testing, as long as it is detected that a porcelain contains such trace elements or the content of such trace elements is high, it can be concluded that it is a fake, on the contrary, if the "sample composition" is "in good conformity" with the ancient porcelain, the possibility of a fake can be ruled out and recognized as genuine.

However, if nothing else, to make an ancient porcelain fake, weishenme, you have to add "modern chemical preparations containing certain trace elements"? Just like the current plain three-color bowl, the forger uses the glaze refined from ancient porcelain, in this case, using the elemental analysis method, it is impossible to distinguish the authenticity.

However, this bowl uses some old methods, so with the elemental analysis method, the authenticity can still be detected.

However, Chu Chen just found that at the bottom of this bowl, there is a mouth the size of a rice grain, which looks very new, so this must be a thermoluminescence dating jishu, and the test is carried out, otherwise the results will not show that this plain three-color bowl will be genuine.

And if it is detected by thermoluminescence generation jishu, this bowl, not to mention irradiated with X-rays, is the old bottom tire it uses, and the use of thermoluminescence generation jishu will only detect that it is true. After all, if you do this kind of test, it is impossible to make a hole in other places except the bottom.

Director Gao listened to what Chu Chen said, and his face was surprised: "Ah! Pick-up? How is this possible, this bowl is obviously integrated, how can it be the old bottom tire? ”

Chu Chen saw that Curator Gao didn't believe it, so he pointed to a place in the bowl and said, "Curator Gao, this bowl is indeed very real, but I have to say that it still has flaws, don't believe you touch here, do you feel the ups and downs?" ”

Hear here. Director Gao hurriedly went up with his hand to feel it, but he didn't expect it to be as Chu Chen said. That place was indeed a little higher than the surroundings, and this situation couldn't help but surprise Director Gao.

Someone might say. Isn't it just a little higher than somewhere else, what's the problem? Maybe it was due to a mistake by the craftsmen of the time?

However, Director Gao knew that this situation would not be caused by a mistake at all, even if it was a bowl used by ordinary people, the inner wall would be smooth when touched, let alone something made by the official kiln? Now this situation must be caused by the imitator's carelessness when repairing the tire.

Although Director Gao knew that there was a problem with this bowl, it was at the time of the acquisition. This bowl cost more than 100,000 yuan, if it was a fake, not to mention that he was distressed, he would have to bear a lot of responsibility, after all, this bowl was originally decided to be accepted by him.

So, Director Gao asked reluctantly, "Mr. Chu, besides, I don't know if you have found any other problems?" ”

"Yes!"

Although this is a bit cruel to Director Gao. However, this is an antique, and there is no room for sloppiness, so Chu Chen still nodded affirmatively.

"Which ......"

Before Director Gao finished speaking. I saw a middle-aged man in his forties, and a man in his thirties and sixties, who looked like Sven. rushed to the front of everyone.

The middle-aged man took a breath and said, "Curator." Is there anything you are in a hurry to get us back? ”

"Hey!" Curator Gao sighed and said, "Let Xiao Zhang tell you." ”

Thereupon. The staff member named Xiao Zhang briefly told the two of them about the matter, and the two of them were also surprised after listening to the cause and effect. But after being surprised, the middle-aged man smiled and said: "I said a long time ago that Zhao Yiping is not a good person, you see, I am right!" ”

Director Gao reprimanded: "Jin Yan, what are you talking about now, since you have long thought that Zhao Yiping is not a good person, why haven't I heard you say it before?" ”

Jin Yan shrugged his shoulders and said, "Curator, it's not that I don't have evidence, otherwise I would have told you a long time ago." ”

Director Gao shook his head and said, "Anyone can put the afterthought, so you better say a few words." Come, let me introduce you first. ”

After speaking, Director Gao introduced Chu Chen and Jin Yan respectively, and through the introduction, Chu Chen also knew another man, named Sun Qiang, who was the little Sun teacher mentioned before.

The two of them saw that Chu Chen was so young, and they didn't look down on him, on this occasion, they didn't have any ability, and Director Gao would not introduce them to both parties so solemnly, plus Chu Chen was Liu Lao's senior apprentice, Jin Yan and Sun Qiang's attitude towards him was very enthusiastic.

However, the two of them were very enthusiastic about Chu Chen, and Li Beibei, who was standing on the side, also experienced their enthusiasm. Especially Sun Qiang, when he shook hands with Li Beibei, he kept staring at her intently, with an expression comparable to a nymphomaniac, he almost didn't drool, and he held Li Beibei's hand, but he refused to let go.

However, Li Beibei was so good, and Sun Qiang immediately paid the price for his actions.

I saw Li Beibei shake it in annoyance, Sun Qiang woke up from the state in an instant, his face was pale in pain, cold sweat broke out, and he begged Li Beibei to let him go, and the people around him laughed secretly. Xiao Zhang even secretly scolded that he deserved it, who told you to be so and often flirt with female employees, now retribution is coming.

Li Beibei sneered again and again, and waited until he felt that the lesson was almost over, so he let Sun Qiang go, but if it weren't for the inconvenience of the current occasion, she wouldn't have spared him so easily.

At this time, Director Gao smiled and said, "Okay, Mr. Chu, you can continue." ”

He has seen it now, it can't be fake, it can't be fake, since the matter has happened, covering his ears and stealing the bell can't solve the problem, making up for the loss and recovering the loss as much as possible is what he should do now.

Chu Chen picked up the bowl and said, "Okay, let's talk about the problem of this bowl." ”

Seeing this, Jin Yan asked strangely: "Hey, isn't this the three-color bowl that I thought was not real before?" What, is there really a problem? Looks like I was right! ”

Hearing Jin Yan say this, Director Gao's stomach was really angry, and he said angrily: "Jin Yan, don't you fight as an afterthought, you said that there was a problem, I asked you where the problem was, and you couldn't say why." Now that you say that again, then let me ask you, what is the problem with this thing, you can't tell it, I will deduct your bonus for this month! ”

After Jin Yan heard this, he was also a little embarrassed, after all, he was a porcelain appraisal expert in the collection department, and he couldn't see the problem of fakes, which was also his shame, so he said hesitantly:

"This ...... Curator, I just think that this thing has a thief light, unnatural, it stands to reason that such an official kiln thing, there should not be this situation, so I came to the inference, but the specific place, I really can't see it. ”

After listening to what Jin Yan said, Chu Chen said: "What Mr. Jin said is indeed right, this thing is a thief light, as for this thief light, it is nothing else, it is this clam light." ”

"Clam Light?"

After listening to what Chu Chen said, everyone looked at the bowl one after another.

Clam light refers to a kind of colored film produced on the surface of porcelain by the erosion of external physical and chemical substances and the changes that occur in the glaze porcelain and low-temperature lead-glazed porcelain containing lead.

After a few decades of lead-glazed porcelain, the color surface will naturally oxidize to produce a kind of colored light, and when you look sideways, you can faintly see the colorful light on top of the color.

There is also a light side-view color around the color material, which is closely surrounded by a faint colorful aperture. With the increase of "porcelain age", this colored film will slowly increase and thicken, and when it reaches a certain thickness, it will produce a flickering "colored light" similar to the inside of a clam shell, so people call it "clam light".

Because these colors and paintings of the Kangxi Dynasty are low-temperature lead-containing glaze, the hardness of the glaze and color glaze is higher after firing, and after the passage of time, under the natural oxidation, this kind of clam light will be formed. And the three-color dragon pattern bowl in front of me has an obvious clam light, which looks very beautiful.

"Mr. Chu, are you saying that this clam is just added? I think it's true! Jin Yan said with a frown.

Chu Chen smiled and said, "Teacher Jin, the clams on this bowl are indeed quite real at first glance, but let's compare the details, it is up for discussion." ”

"I think you also know that the real clam light is closely around the color, very small and uniform aperture, the clam light is more obvious in the place where the color is thick, and the clam light is lighter in the place where the color is thin. The aperture of the fake clam is thicker, flaky, and unnatural, and the aperture around the intense color is as obvious as the aperture around the light color, which is not as natural as the real one. ”

"That person, it's really powerful, I don't know how he did it, some details are the same as the real thing, especially the beating, active, smart, and deep feeling of the real clam light, and it was actually made, which I really admire."

"But, it can't really be fake, and it can't be fake, you see the clam light in this thin color, it's actually the same as the colorful place next door, you think, is it really possible? And look at it again, on these two leaves, there will actually be clam light, although there are not many clam lights on the leaves, but if this is really a vegetarian three-color bowl in the Kangxi period, do you think it is possible? ”

The naturally formed clam light will only be around the color material, of course, not on the color material, hearing this, even Professor Qin and others, who are not proficient in porcelain identification, understand that this clam light must be artificially added.

At this time, Jin Yan finally knew that he would feel this way. Although this clam light is indeed very real, but there is a saying that details determine success or failure, just like a rat droppings that spoil a nest of porridge, it is these places that make the clam light not so natural, so that the whole gives him an awkward feeling.

Of course, this feeling is only felt by some experienced experts, and ordinary people will only think that this bowl is genuine. (To be continued......)
