Chapter 568

The value of Mr. Niu's two Xuande blue and white porcelains should be around 10 million yuan. If you buy these two important wares for 5 million yuan, it must be worth the money. But the original owner can't be so stupid, but the ten million things only cost 5 million yuan. Of course, it is very likely that the original owner didn't know the specific value of the East and West, so he took advantage of Mr. Niu.

But Xuande blue and white porcelain is very famous. Wouldn't the original owner go to identify it before mortgage? Or is it based on the price of a few years ago?

If these two things are genuine, then there is no doubt about everything, but these two things have some problems, so we have to think more about them.

"What do you think, Xiao Chu?" Guan Guokang turned his head and asked chuchen next to him.

"I don't think either of these things is true!" Chu Chen said so.

"Mr. Chu, since you don't think these two things are true, there must be a reason." Mr. Niu stares at Chu Chen tightly and says that this is not tens of thousands of things, but tens of millions of things. Even if he has hundreds of millions of wealth and tens of millions of losses, he will be distressed for a while, so he has to ask clearly anyway.

As a matter of fact, when Chu Chen just came here, he had already used his powers to identify them. In the two kinds of porcelain, there was no power at all. Therefore, these two things must be fakes made in modern times.

However, the result given by the power can't be used as a reference, so he carefully observed the two objects while everyone was talking, and he lost no time in knowing the authenticity of the objects in advance. Otherwise, it's not so easy to find several different places from the real objects.

"There must be a basis for me to say that."

Chu Chen first picked up the big plate and said, "let's talk about this blue and white plate, the real Xuande official kiln porcelain. With a magnifying glass, we can see that the bubbles in the shaft form large, medium and small bubble groups. The moments between groups are relatively sparse, while the bubbles in the glaze of this plate are dense and neat, which is not consistent with the characteristics of the real product."

Hearing this, Wang Xiangong said, "well, Xiao Chu, I just looked at it with a magnifying glass. Why didn't I see the phenomenon you said?"

The others nodded, indicating the same.

Chu Chen said with a smile: "the reason is very simple. You use the magnifying glass prepared here. You can only magnify it 20 times at most, but this phenomenon can only be seen with a magnifying glass 30 times. If you don't believe me, just look through my magnifying glass. "

Then he put his 30 times magnifying glass on the table.

After listening to Chu Chen's explanation, we were surprised and took turns to observe the dish with Chu Chen's magnifying glass. We found that the bubbles in the glaze were exactly what Chu Chen said.

At this time, Mr. Niu had a bad feeling in his heart. Judging from the current result, his blue and white plate may be a fake, but he was not reconciled, so he said with insufficient confidence: "this, is it an individual phenomenon?"

After all, it's worth millions of such valuables. Mr. Niu's performance was not surprising. He went to his position and said hello to the treasure holder. Then he took a small blue and white bowl and said:

"Mr. Niu, I'm sorry, this phenomenon is common in Xuande blue and white. If you don't believe it, you can have a look at it This Xuande bowl will tell. "

Mr. Niu had a bitter smile. He also knew that Chu Chen was sure of what he said, so he waved his hand and said, "Mr. Chu, I believe what you said!"

And the holder of this small bowl immediately ran over with a look of excitement and asked excitedly, "Miss Chu, do you mean my bowl is genuine?"

"Yes, congratulations. This bowl is a real one." Chuchen nodded with a smile.

The man almost jumped up when he heard the exciting news. After a long time, he calmed down and asked, "how much is my bowl worth?"

Chu Chen pondered for a while, and then said, "I estimate that it's about 3.5 million to 4 million. If it's on the auction, it might be even higher."

"This So valuable? " When the man heard the unexpected price, his eyes almost glared out, and others looked at him with envy.

"That's true!" Chu Chen definitely nodded and said, "but this gentleman, I'd like to trouble you. Can this bowl be a reference for us? You can rest assured that it will be ready in a moment."

That person is also more atmosphere, did not think much nodded to agree to come down.

At this time, Guan Guokang said: "Xiao Chu, is there no difference between this plate and the real one except for bubbles?"

"Yes, could the forger have imitated Su Bo Ni Qing?" Yu renpeng asked immediately.

"It's not that easy!" Chuchen shook his head with a smile: "you teachers should also know that the" rust spot "formed by Su Bo's Clay Green is formed by the accumulation of iron ions in the thick part of the green material in the decoration and the secondary oxidation, which has its special distribution law. The imitations add more iron to the chemical green materials, and there will be "rust spots" and "tinsel" after firing"But the imitation is imitation after all. The distribution of" rust spots "made in this way will not be so regular. If it is too much, the density and concentration of" rust spots "will greatly exceed the content of iron in sumaliqing. For example, the" rust spots "on this plate are denser than the real ones, but the counterfeiters have higher skills. This phenomenon can only be seen through careful observation Come out. "

"In addition to" rust spots ", because the proportion of Su Bo Clay Green is large, if the kiln temperature is normal, it will not diffuse to the glaze surface, but will faint at the bottom of the glaze juice. This makes the side look at the glaze will find that all the green material decorative part has concave phenomenon, but the green material is very light place is not obvious. But it's not obvious on this plate. It's also different from the real one... "

Chuchen talked with great enthusiasm, and other people immediately wrote down what chuchen said word for word. This is an experience. Maybe it took them a long time to understand, and the experience of these words may have prevented them from losing.

"If only I had known that before!" Mr. Niu sighed to himself.

Yu renpeng pointed to another plum vase and said, "little Chu, what about this plum vase? I have just seen as like as two peas, the characteristics of the bubbles inside the glaze, or the "rust spot" and the sag phenomenon you just mentioned, are exactly the same as genuine ones.

"That's what I admire about the forger, but it's not true. It's not so easy to imitate Su Bo's performance."

Chu Chen said: "let's just say" rust spot ". If we observe it carefully, we can find some differences from the real product. However, because the difference is relatively small, I won't say more about this. I would like to talk about the unique Beaded condensation phenomenon of Su Bo Ni Qing

"The bead like condensation phenomenon of this kind of pigment will appear not only when using thick green material to smear parts such as people's clothing, but also when using thick material to sketch fine lines such as palindrome. Obviously, the counterfeiters also found this phenomenon and deliberately imitated it, but the imitation was very unnatural. "

At this point, Chu Chen picked up the real one and said: "the cause of beaded condensation is the original metal oxide left by coarse particles insoluble in glaze. They are distributed in the direction of a few bowls in the form of dots and condensation. This is in line with the characteristics that the small particles that are not finely ground are carried by the craftsman's brush, leaving traces of distribution along the direction of the brush. "

Speaking of this, Chu Chen picked up the blue and white plate again: "but on this blue and white plate, it's different. Have you found that these places are distributed in the shape of stems and veins? That is to say, it will cross or even perpendicular to the direction of the pen

"This is because our current pigments are very fine and evenly distributed. They dissolve in the glaze at high temperature. These dark colors are iron oxides formed by iron ions absorbing oxygen in the original process, so they can not be distributed along the direction of the pen. That's why there are veins like stems that cross or even vertically distribute with the direction of the pen."

"In addition, I started a kiln some time ago, so I also studied this information. I think the appearance of vein like appearance may be related to the gas kiln we use now. "

Chu Chen said: "we know that only when the temperature is enough and the time is enough, can we ensure the full oxidation of Fe2O3 in green materials and make the glaze melt more completely. But our present gas kiln only takes ten hours. Although the time has been shortened, there will certainly be traces of haste in the process of green material and glaze melting, which is just like the performance of stem vein, which should be the traces of this. "

At this point, Chu Chen picked up the plum vase: "just now, I think this blue and white plate should be a test object of the counterfeiter, so some places will have the performance of stem and vein, but this plum vase does not have that performance, I think it should be that the counterfeiter used the cosolvent."

"But in this way, there is another problem. The use of cosolvent will make the firing time insufficient. Although the counterfeiter took remedial measures, it still makes the blue and white hair color unclear. If you look at it alone, it may not be easy to see, but it is very obvious when compared with the real one."

Then Chu Chen put the plum vase next to the real one. By comparison, as long as there is no eye problem, we can find the difference between the two.

After more than a minute, I didn't know who was the first to clap. Then, other people at the scene clapped for Chu Chen
