When Chu Chen saw the painting in front of him, he was shocked, but on the surface, he was still. Therefore, we didn't find anything wrong in Chu Chen's expression.

When Chu Chen looked up, he asked with a smile:

"boss Chu, can you still see this painting in your eyes?"

considering that as like as two peas in the eyes, Chu Chen said directly, "old, I am, to tell the truth, this" Song Crane "has a picture of my master, and it is the same everywhere except the small part.

"What?! Boss Chu, are you not mistaken? "

Lao Chang's face immediately showed an incredible look after hearing this, and other people also felt incredible.

Chu Chen shook his head: "I'm sorry, that's the truth, and the title and the location of the bell seal of the two paintings are the same."

Hearing this, everyone looked at each other. After a while, Xiang Facai frowned and asked, "is this painting copied? It doesn't look like it! "

"It's right to say copy, but it's more complicated than copy." Speaking of this, Chu Chen looked at Lao Chang.

Based on Lao Chang's experience, when he heard Chu Chen say so, he could not imagine what Chu Chen said. He frowned and said, "boss Chu, do you think this painting is" exposing the second floor "

"Uncover the second floor"? What do you mean Xiang Facai hears the speech some doubts of ask a way.

"Uncovering the second level is actually a way of falsification..." Chu Chen explained the meaning of "uncovering the second floor".

"Isn't it true that one painting can be turned into two paintings? How great skill is it to be able to do that?" After listening to Chu Chen's explanation, Wu Ke and others were shocked.

Chu Chen said: "of course, it's not easy to uncover the second layer. The counterfeiter needs to go through quite complicated steps, such as mounting, repairing and full-color, to make a painting that is enough to confuse the real with the fake..."

Generally speaking, if you want to "uncover the second layer", the steps are very similar to "uncover the old" in the restoration of ancient paintings and calligraphy. You must first observe the degree of damage and the characteristics of the times of the old paintings and calligraphy, and then go through the processes of picking and scraping stains, cutting the heart of the painting, washing stains, uncovering, repairing, and panchromatic.

To pick up and scrape stains and square cut painting heart is to gently pick up and scrape off some frivolous stains on the surface, such as dust, mildew, black spots or water marks. Generally, sharp angle knife or horseshoe knife is used. The operation needs to be very careful. The force is light and uniform, and gradually scrapes along the edge of the stain. Then, cut off the old edges and trim the edges of the heart.

Then there's cleaning. At this time, the general use of boiling water, because if it is more recent calligraphy and painting, with cold water may appear ink phenomenon. But for ancient paintings, its color will not be easily washed and dropped by water.

Because of the strong stickiness of rice paper and ink, the paper should be soaked with boiling water first, and then the paste in rice paper should be soaked. After soaking with boiling water, add a layer of plastic film on the painting center, then pour boiling water, spread and press it around with towel, and pour it once a few days.

In summer, the time interval of watering is longer, but the painting and calligraphy should be prevented from getting moldy. According to the mounting master who was once familiar with "removing the second layer", sometimes it takes half a month to repair some old paintings, but the color will not fall off.

After cleaning, it is the key step of "exposing the second layer".

"Uncovering" refers to uncovering the back covering paper and the heart support paper of the original mounting piece. Usually, to uncover the old is to soak the painting and calligraphy in water and rub off the back covering paper and the painting heart support paper bit by bit. Almost all of them are uncovered in small pieces. But the whole story has to be uncovered. The more layers you uncover, the lighter the ink.

In the restoration of ancient calligraphy and painting, "mending" is to add appropriate materials to the incomplete parts of historic sites, but in "exposing the second floor", it is to nod to Chu Chen and say: "this kind of thing was a difficult problem in the past, but now there is high technology, and the counterfeiter can almost make the seal as it is. In addition, the old inkpad is used in the old calligraphy and painting, because it is only a hundred years old, and it can still be found now. Therefore, the seal is no longer the bottleneck of "uncovering the second layer."

Seeing Xiang Facai nodding his head repeatedly to show his understanding, Lao Chang, who was standing aside, felt very unhappy. After thinking about it, he said, "although exposing the second layer is a method of falsification, it can't be denied that the uncovered painting was painted by the original author?"

We all know the meaning of the old saying. It just means that even though his painting is a two-story painting, it is also from Xugu's works and is of great value.

Xiang Facai laughed, but his smile was contemptuous: "Lao Chang, if your painting is the first layer, I don't object to your saying so, but your painting is the second layer, and it has been repaired. Can you compare it with Xugu's own painting? At most, it's a semi-finished painting! "

Lao Chang opens his mouth, trying to explain, but he can't find the corresponding reason. If it hasn't been repaired, then at this time, he can still say that the price of this painting is almost the same even if there is no authentic one, but there is no way. Who calls his painting "exposing the second layer" congenital deficiency?

At this time, Xiang Facai looked at the time, and it was almost eleven o'clock. He said patiently: "Lao Chang, although your painting is really valuable, I won't want this kind of thing. If you have any good things, you can take them out. We still have things to do. We don't have time to spend them here. "Lao Chang was relieved when he heard Xiang Facai's words, because Chu Chen could see that the painting was "exposing the second floor". The original subordinate couldn't see it, but Xiang Facai couldn't refuse it if he insisted on it. Now Xiang Facai doesn't want it, it's in his heart.

But then, Lao Chang began to worry again. He could not offer any good things to Xiang Facai. What could he do?

Thinking about it, Lao Chang could only say, "Mr. Xiang, I really don't have anything good here. If you don't believe me, I can take you to my collection room."

"Let's have a look!"

Xiang Facai immediately waved his hand when he heard this. The results of the previous two things made him feel that Lao Chang's eyesight was not very good. Maybe there was something missing in the rest of Lao Chang's things, which could help Chu Chen find out. Of course, even if not, he would not let Chang go.

"The fat man is very fast."

Chu Chen murmured to himself that he originally wanted Xiang Facai to take the painting and buy it for Mr. Liu to see. However, Xiang Facai's response was so quick that he didn't even have a chance to wink. In that case, he can only wait until he has a chance.
