Chapter 245 Clam Light

From the above, when testing, as long as a certain porcelain is detected to contain this trace element or the content of this trace element is too high, it can be concluded that it is a fake. The possibility of counterfeiting can be ruled out and it can be identified as genuine.

However, apart from other things, why do you have to add "modern chemical preparations containing certain trace elements" to make ancient porcelain fakes?Just like the plain three-color bowl now, the forger used the glaze extracted from ancient porcelain. In this case, with elemental analysis, it is impossible to distinguish the authenticity from the fake.

However, this bowl has used some old-fashioned methods, so elemental analysis can still be used to verify the authenticity.

However, Chu Chen discovered just now that there is a hole the size of a rice grain in the bottom of this bowl, which looks very new, so this must be the thermoluminescence dating technology, otherwise the result would not show this bowl. The plain three-color bowl will be the real thing.

And if the thermoluminescence dating technique is used for the detection, this bowl, not to mention the X-ray irradiation, even the old base it uses, can only be detected by the thermoluminescence dating technique to be real.After all, when doing this kind of inspection, it is impossible to make holes in other places except the bottom.

After hearing what Chu Chen said, Curator Gao was very surprised: "Ah! Laodi took over the fetus? How is this possible? This bowl is clearly a whole body. How could it be Laodi's delivery?"

Seeing Director Gao's disbelief, Chu Chen pointed to a spot inside the bowl and said, "Director Gao, this bowl is indeed a real imitation, but I have to say that it still has flaws. If you don't believe me, touch it here. , Do you feel the ups and downs?"

Hearing this, Director Gao hurriedly felt it with his hands, but he did not expect that it was indeed as Chu Chen said, that place was indeed higher than the surrounding area, which surprised Director Gao. .

Some people may say, isn't it just a little higher than other places, so what's the problem?Maybe it was due to the craftsman's mistake at that time?

However, Director Gao knew that this situation could not be caused by mistakes at all. Even the bowls used by ordinary people have a smooth inner wall, let alone something made by an official kiln?The current situation must have been caused by the imitator accidentally not paying attention when repairing the tire.

Although Director Gao knew that this bowl was probably faulty, but at the time of purchase, this bowl cost more than [-] yuan. If it was a fake, not to mention his distress, he would have to bear a lot of responsibility After all, he decided to accept this bowl at the beginning.

So, Director Gao asked persistently: "Mr. Chu, besides this, I wonder if you have found any other problems?"

"Have!"

Although this was a bit cruel to Director Gao, the appraisal was an antique, and there was no room for sloppyness. Therefore, Chu Chen nodded affirmatively.

"where……"

Before Director Gao could finish speaking, he saw a middle-aged man in his 40s and a gentle-looking man in his 35s rushing to the front of the crowd.

The middle-aged man took a deep breath and said, "Curator, why are you so anxious to let us come back?"

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

So, the staff member named Xiao Zhang briefly explained the matter to the two of them. After hearing the cause and effect, the two were also very surprised.But after being surprised, the middle-aged man smiled and said: "I said 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 believed that Zhao Yiping is not a good person, why didn't I hear you say it before?"

Jin Yan shrugged and said: "Curator, it's not that I don't have evidence, otherwise I would have told you."

Director Gao shook his head, and said, "Anyone can put the gun in hindsight, so you should say a few words less. Come, let me introduce you first."

After finishing speaking, Director Gao introduced Chu Chen and Jin Yan respectively. Through the introduction, Chu Chen also got to know another man named Sun Qiang, who was the previously mentioned Teacher Xiao Sun.

Seeing how young Chu Chen was, the two of them didn't look down on him at all. On such an occasion, they didn't have any skills, and Director Gao wouldn't introduce them to both parties in such a serious way. Besides, Chu Chen belonged to Mr. Liu. Gao Tu, Jin Yan and Sun Qiang were all very enthusiastic towards him.

But the two of them are not only very enthusiastic about Chu Chen, but Li Beibei, who is standing by the side, also feels their enthusiasm.Especially Sun Qiang, when he shook hands with Li Beibei, he kept staring at her intently, with a nympho expression, almost drooling, and holding Li Beibei's hand, he just refused to let go.

But Li Beibei didn't agree with him like this, Sun Qiang immediately paid the price for his behavior.

Seeing that Li Beibei gave him an annoyed grip, Sun Qiang woke up instantly from the nympho state. He was so painful that his face turned pale and he broke out in cold sweat. He laughed secretly.Xiao Zhang even cursed inwardly that you deserve it, who told you to be so lecherous and often molested female employees, now come your retribution.

Li Beibei sneered again and again, and only let Sun Qiang go when he felt that the lesson was almost done, but if it weren't for the inconvenience of the current situation, she wouldn't let him go so easily.

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

He has also seen it now, the truth cannot be false, and the false cannot be true. Since the matter has already happened, lying to the ear and stealing the bell cannot solve the problem. It is what he should do now to make up for it and try to recover the loss as much as possible.

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

Seeing this, Jin Yan asked strangely: "Hey, isn't this the three-color bowl that I thought was unreal before? Why, is there really a problem? It seems that I was right at the beginning!"

Hearing what Jin Yan said, Curator Gao was really angry, and said angrily: "Jin Yan, don't be an afterthought, okay? You said there was a problem at the beginning, and I asked you what the problem is. You I can’t tell you why. Now that you say that again, I’ll ask you, what’s the problem with this thing, and if you can’t tell, I’ll deduct your bonus for this month!”

After Jin Yan heard the words, he was also a little embarrassed. After all, he is an expert in porcelain appraisal from the collection department. It is also his shame that he can't see the problem of fakes, so he hesitated and said:

"This...curator, I just feel that this thing is stealthy and unnatural. Logically speaking, such a thing from an official kiln should not have such a situation, so I made an 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 has stealth light. As for the stealth light, it is nothing but clam light."

"Clam light?"

After hearing what Chu Chen said, everyone looked at Wan.

Clam light refers to lead-containing glazed porcelain and low-temperature lead-glazed porcelain, which are eroded by external physical and chemical substances and their own changes, resulting in a colored film on the surface of the porcelain.

Porcelain with lead glaze will naturally oxidize into a kind of colored light after decades of color surface. When you look at the light from the side, you can faintly see the colorful light on the colored surface.

There are also faint colorful apertures surrounding the light-facing side-view color material.As the "porcelain age" increases, this colorful membrane will gradually increase and thicken, and when it reaches a certain thickness, it will produce a "colored light" similar to the flickering inside the clam shell, so people call it "Clam Light".

Because these colored grounds and colored paintings in the Kangxi Dynasty are low-temperature lead-containing glazes, the hardness of the glazed surfaces and colored glazes after firing is relatively high. After time, natural oxidation will form this kind of clam light.And the Huangdisu three-color dragon-pattern bowl in front of me has obvious clam light, which looks very beautiful.

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

Chu Chen chuckled and said, "Mr. Jin, the clams on this bowl are indeed real at first glance, but we have to discuss the details when we compare them."

"If you want to come to Mr. Jin, you also know that the light of the real clam is tightly surrounded by the color, and the aperture is very small and uniform. The light of the clam is more obvious in the place where the color is thick, and the light of the clam is weaker in the place where the color is thin. The fake clam light circle It’s rough, flaky, and unnatural, and the halo around the thick color is as obvious as the halo around the light color, not really that natural.”
"That person is indeed very powerful, and I don't know how he did it. Some details are just like the real ones, especially the beating, lively, agile, and deep feeling of the real clam light. , this, I really admire."

"However, the real can't be fake, and the fake can't be real. You can see that the clam light in this thin-colored place is the same as the thick-colored place next door. Do you think this is really possible? And look again, this There are clam lights on the two leaves, although there are not many clam lights on the leaves, but if this is a real plain three-color bowl from 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 the clam light must be artificially added .

At this moment, Jin Yan finally knew why he felt this way.Although the clam light is indeed very real, but it is said that the details determine success or failure, just like a rat droppings spoiling a nest of porridge, it is these few places that make the clam light not so natural, so that It gave him an awkward feeling overall.

Of course, this kind of feeling can only be felt by some experienced experts, and ordinary people will only think that this bowl is the real thing.
