Shen Zhongyuan's expression was a little solemn, and he didn't ask for a while.

Yu Yao exhaled a long breath, "Elder Shen, there is something wrong with this painting. ”

"What do you say?" Shen Chongyuan's heart sank.

"Let's talk about the material first, this painting silk is an old silk, but Song Juan, not Tang Juan. ”

"Ah? I have studied it carefully, and this is a single silk ripe silk, not a double silk ripe silk! The silk used for framing is indeed true in the early Qing Dynasty. Shen Chongyuan's eyesight, objectively speaking, is not as good as Yu Yao, but he is by no means mediocre.

Silk and silk both belong to silk, and the main difference is that silk is a plain silk fabric, and silk is a twill silk fabric. Therefore, silk is more suitable for painting, and silk is more suitable for framing.

Silk is divided into raw silk and cooked silk, and the raw and cooked rice paper is a little similar, raw silk is untreated, strong water absorption; cooked silk is treated, not easy to absorb water.

Before the Tang Dynasty, raw silk was mostly used for painting. The appearance of ripe silk in the early Tang Dynasty became a basis for the prevalence of gongbi painting in the Tang Dynasty. Because of its strong water absorption, it is difficult to draw a fine brush.

Silk is also divided into single filament and double filament, which is very simple, single warp and single weft is single filament silk, and double warp and single weft is double filament. Connoisseurs can see it with a magnifying glass.

Tang painting on silk is a single silk silk, and during the Five Dynasties, it gradually began to appear to paint with double silk.

Therefore, if the silk book with a double silk is said to be a Tang painting, the connoisseur can deny it based on this alone.

But the other way around, you can't use it that way.

After five generations, double silk silk appeared, which does not mean that the silk after five generations will no longer use single silk silk. Five generations later, there was still the use of monofilament silk, and there were ups and downs. In the Song Dynasty, it was common to see single filament and double filament, and in the Ming Dynasty, it was mostly double filament, but in the Qing Dynasty, it became mainly monofilament, and double filament was rare.

Of course, Shen Chongyuan is not judged only by a single silk, but also by combining the characteristics of some other paintings.

"Monofilament silk is not the point. The point is that the processing method of this cooked silk cannot be from the Tang Dynasty. ”

Yu Yao then explained, "It's not easy to discern, especially after a thousand years, but it's not like there's no way at all. The cooked silk of the Tang Dynasty could not be brushed, and the Song Dynasty had a comprehensive method of boiling and brushing; therefore, from the texture of the silk and the change of silk color, we can find out the clues that it is not Tang Juan but Song Juan. ”

"No wonder you've been looking at it with a magnifying glass for so long!" Shen Chongyuan gasped, "I don't know what to say!" Last time, you used the 'metaphysical' method to identify the old Su piece imitating Dong Qichang, but now you are meticulous about the silk!"

"Let's analyze the specific problems in detail. Yu Yao said in his heart, this is indeed a lot of effort!

"So, this is a Tang painting imitated by the Song people?"

Yu Yao shook his head again, "The silk is Song Juan, but the painting is not a Song painting!"

"What? Could it be that it is the same as the framing material, it is an imitation of the early Qing Dynasty, and Song silk is used?"

"This ······"

"It's okay to put it bluntly, I didn't really spend the money of a Tang painting, and my Mingjun flower pot was given to an old friend for nothing?"

"Don't talk about the beginning of the Qing Dynasty, I'm afraid I won't even be able to reach the Republic of China!"

"Modern imitation?!so clever?!" Shen Chongyuan's face suddenly changed color.

"Very clever indeed. ”

Yu Yao paused, and then explained in detail, "There are two big problems with using old silk paintings from the Song Dynasty to make old ones. First, if it is an old painting, the pigment will change over time and slowly penetrate into the inner texture of the silk, while the new painting will not, and it will need special pigments to penetrate it; and the second, it is natural that the surface will be worn, so that the picture and the silk will achieve a certain consistency. ”

"But this painting is obviously handled very well!" Shen Chongyuan sighed.

"Yes, it was handled very well. The half-seal of the Inspectorate is also flawless. ”

"Originally?"

"If he wants to make a picture of the Song people's imitation of the Tang Dynasty's golden landscape, it may be perfect. But he may be very greedy, or maybe there is another reason to make it a 'Tang Dynasty silk book'!"

Shen Chongyuan frowned, "But you still recognized Song Juan!"

"That's not the point. Although it has not been completely made into the texture and aging state of Tang Juan, it is already extremely difficult to identify, otherwise I wouldn't have to work so hard. The key thing is that while he further processed Song Juan, he also affected the paint of the picture, slightly revealing a little bit of the characteristics that the paint of Tang and Song painting did not have. The reason why I said that I couldn't even reach the Republic of China was because of the particularity of pigments. ”

"Whip in, whip in!" Shen Chongyuan applauded unconsciously.

"I guess this person didn't have Tang silk at hand at that time, but he had to imitate Tang paintings, so he had to spend so much trouble. At the same time, he did not make the original mounting, but used the form of post-warp mounting, also to cover up the problem of silk. ”

Yu Yao said, pacing back and forth, a little talking to himself: "The details here are very particular. In order not to show clues, he did not make other collections of seals, only made half a seal of the Discipline Inspectorate, which was not only precious, but the collection of paintings of the Discipline Inspectorate in the early Ming Dynasty was difficult to examine; at the same time, the calligraphy and painting of the Ming Dynasty was the most likely to flow out at the end of the Ming Dynasty, and it was more authentic to choose to frame it with the old silk in the early Qing Dynasty. Since then, there have been no more collection inscriptions and seals, because the collection of calligraphy and painting after the middle of the Qing Dynasty is relatively easier to verify. ”

"The means are so clever and the thoughts are so dense, he is simply a super master of calligraphy and painting!" Shen Chongyuan sighed again and again, "It's a pity that the magic is one foot high, and the road is one foot high, and you still see through it!"

Yu Yao slowly narrowed his eyes, "This painting is very likely to have been made in the eighties and nineties. If this man were still alive, I would have met him!"

After all, after all these years, my old friend also bought it from an antique shop. I'm afraid I can't find that shop now. Besides, the shopkeeper also collected it from the old peasants. ”

"Where did you get it, it's just the shopkeeper's words, and it's not credible. However, after so many years, it is really impossible to trace it. ”

Yu Yao said on his lips, but he couldn't help but think of someone in his heart.

How to clean.

He Shangshan's level he has seen, this painting list is not much better in terms of imitative painting. It's just that there is something wrong with the silk old. Even this little problem is difficult for him to detect, and it is easy to see the clue.

He didn't know what kind of person He Yidi was or where he was, and judging by his age, it was not unlikely.

But this painting involuntarily made him think, could it be related to He Yidi?

Of course, this is only an association that arises because of Yu Yao's own starting point and experience.

The world is big, there are no wonders, antiques, hidden dragons and crouching tigers. It's normal that this super master has nothing to do with He Yidi.

At this time, Shen Chongyuan looked at Yu Yao, who was thinking heavily, "You are so interested, why don't I ask my old friend and see if I can recall any clues?"
