Chapter 248

According to the above, when testing, as long as a certain porcelain contains this trace element or the content of this trace element is high, it can be judged as a fake. On the contrary, if the "sample composition" is "in good agreement" with the ancient porcelain, it can be ruled out as a fake.

However, among other things, why do we have to add "modern chemical preparations containing certain trace elements" to make ancient porcelain fakes? Just like this plain tricolor bowl, the forger uses the glaze extracted from ancient porcelain. In this case, the authenticity can not be distinguished by element analysis.

However, this bowl has used some old methods, so it can be verified by element analysis.

However, Chu Chen just discovered that there is a big hole at the bottom of the bowl, which looks very new. Therefore, it must have been detected by using thermoluminescence dating technology, otherwise the results would not show that the plain tricolor bowl would be authentic.

If we use the thermoluminescence dating technology for testing, this bowl, not to mention the X-ray irradiation, is the old bottom of the embryo, the thermoluminescence dating technology will only detect that it is true. After all, this kind of testing, in addition to the bottom, it is impossible to make a hole in other places.

After listening to what Chu Chen said, curator Gao was greatly surprised: "ah! How to pick up the tire? How can it be that this bowl is clearly integrated, and how can it be that the old man has a baby? "

Seeing that curator Gao didn't believe it, Chu Chen pointed to a position in the bowl and said, "curator Gao, this bowl is really imitated, but I have to say that it still has flaws. Do you feel the ups and downs here?"

After hearing this, curator Gao quickly felt it with his hands. Unexpectedly, as Chu Chen said, the place was higher than the surrounding area. This situation surprised curator Gao.

Maybe some people will say that it is higher than other places. What's the problem? Maybe it was the craftsman's fault at that time?

However, curator Gao knows that this situation is not caused by mistakes. Even the bowls used by ordinary people have smooth inner walls, not to mention the things made in official kilns? Now this kind of situation is definitely caused by the imitator's carelessness when repairing the tire.

Although curator Gao knew that there was something wrong with the bowl, it cost more than 100000 yuan at the time of acquisition. If it was a fake, he would have to bear a lot of responsibility, not to mention his heartache. After all, he decided to take the bowl.

So, curator Gao asked: "Mr. Chu, besides, do you have any other problems?"

"Yes!"

Although it was a bit cruel to curator Gao, what he identified was antiques, and there was no room for carelessness. Therefore, Chu Chen nodded for sure.

"Where..."

Before curator Gao finished, he saw a middle-aged man in his forties and a gentle looking man in his thirties rushing to the crowd.

The middle-aged man gasped and said, "curator, are you in a hurry to let us come back

"Ah Gao Guan sighed and said, "let Xiao Zhang tell you."

So, the staff member named Xiao Zhang told them the story briefly. After listening to the cause and effect, they were also very surprised. But after the surprise, the middle-aged man said with a smile: "I have said that Zhao Yiping is not a good man. You see, I'm right!"

Director Gao rebuked: "Jin Yan, what sarcastic remarks do you make now? Since you think Zhao Yiping is not a good man for a long time, why didn't I hear from you before?"

Jin Yan shrugged and said, "curator, I don't have evidence, otherwise I would have told you."

Curator Gao shook his head and said, "everyone can shoot after a horse. You'd better say less. Let me introduce you first. "

After that, curator Gao introduced Chu Chen and Jin Yan respectively. Through the introduction, Chu Chen also knew another man named sun Qiang, who was the teacher named Xiao Sun.

When they saw that Chu Chen was so young, they didn't look down on him. On this occasion, they didn't have any skills, and curator Gao didn't solemnly introduce them to each other. In addition, Chu Chen was also an apprentice of Liu Lao. Jin Yan and sun Qiang were very enthusiastic about him.

However, they are not only enthusiastic about chuchen, but Li Beibei, who is on one side, also realizes their enthusiasm. Especially when sun Qiang shakes hands with Li Beibei, he always stares at her. His face, which is comparable to that of a flower maniac, almost doesn't drool. Moreover, holding Li Beibei's hand, he just refuses to let go.

But Li Beibei, who is this with good, sun Qiang immediately paid the price for his behavior.

With Li Beibei's angry grip, sun Qiang instantly wakes up from the state of flower mania. The pain is that he turns pale and sweats. He repeatedly implores Li Beibei to let him go. The people around him are laughing. Xiao Zhang deserves to scold you secretly. Who told you to be so lecherous and often molesting female employees? Now the retribution is coming.

Li Beibei sneers, waiting for him to learn a lesson, then she lets sun Qiang off. But for the inconvenience of the present situation, she would not have spared him so easily.At this time, the head of Gaoguan said with a smile, "well, Mr. Chu, you can go on talking."

Now that things have happened, hiding one's ears and stealing one's bell can't solve the problem. It's what he should do now to mend the situation and recover the loss as much as possible.

Chu Chen picked up the bowl and said, "well, let's talk about this bowl."

Seeing this, Jin Yan asked strangely: "eh, isn't this the tricolor bowl that I didn't think was true before? What, is there really a problem? It seems that I was right at the beginning! "

Hearing what Jin Yan said, curator Gao was so angry that he said, "Jin Yan, don't be a backseat, OK? When you said there was a problem, I asked you where the problem was, you couldn't tell why. Now you say that again, I'll ask you what's wrong with this thing. If you can't tell me, I'll deduct your bonus this month! "

After hearing this, Jin Yan was also a little embarrassed. After all, he was an expert in porcelain identification in the collection department. He could not see the problem of forgery, which was also his shame, so he faltered and said:

"this Curator, I just think it's a bit of a thief and unnatural. It's reasonable to say that there should be no such thing in such an official kiln. That's why I came to the conclusion. However, I really can't see the details. "

After listening to what Jin Yan said, Chu Chen said: "what Mr. Jin said is really right. This thing has a thief light. As for the thief light, it's nothing else. It's the 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 color film on the surface of lead containing overglaze color porcelain and low-temperature lead glaze porcelain, which is eroded by external physical and chemical substances and changes in itself.

After several decades, the color surface of porcelain with lead glaze will naturally oxidize a kind of color light. When you look at the side facing the light, you can see the bright light above the color.

There is also a side view of the light, the color material is closely surrounded by a light colorful aperture. With the increase of "porcelain age", this kind of color film will gradually increase and thicken. When it reaches a certain thickness, it will produce a kind of "color light" similar to that in clam shell, so people call it "clam light".

Because these colors and paintings of the Kangxi Dynasty were low-temperature lead glaze, the hardness of the glaze and colored glaze was higher after firing. After the passage of time, the clam light was formed under the natural oxidation. And in front of this yellow earth element tricolor dragon bowl has obvious clam light, looks very beautiful.

"Mr. Chu, do you mean the clam was added? I think it's quite true! " Jinyan frowned and said.

Chuchen said with a smile: "Mr. Jin, the clam on this bowl is really real, but we need to discuss the details."

"As you know, Mr. Jin, the light of real clams is closely around the color, with a very small and uniform aperture. The light of clams is more obvious where the color is thick, and lighter where the color is thin. And the aperture of the fake clam is thick, flaky and unnatural, and the aperture around the thick color is as obvious as that around the light color, which is not really so natural. "

"That man is really powerful, and I don't know how he did it. Some of the details are the same as the real thing, especially the beating, active, flexible and deep feeling of the real clam light. I really admire that."

"But it's not true, it's not true. Look at the clam light in this place with thin color, it's the same as the place with thick color next door. Do you think it's really possible? Moreover, you can see that there are clam lights on these two leaves. Although there are not many clams on the leaves, if it is a real Su Sancai bowl in the reign of Emperor Kangxi, do you think it is possible? "

Naturally formed clam light is only around the colored materials, but certainly not above them. Even Professor Qin and others, who are not proficient in porcelain identification, understand that the clam light must be added artificially.

At this time, Jin Yan also finally knows why he has this kind of feeling. Although this clam is really true, it is the details that determine the success or failure, just like a mouse excrement spoiling a nest of porridge. It is these places that make the clam light not so natural, so that it gives him a kind of uncomfortable feeling on the whole.

Of course, this feeling is only felt by some experienced experts. Most people only think that this bowl is genuine.
