The girl listened to Pu Jie's words, and she didn't feel embarrassed at all, "Such a good wine is indeed rare, just say it's okay, right?"

"I said for a long time that you don't believe it, just these two kinds of wine on the table. Pu Jie blinked, "Maybe it's because of the effect of the mixed heating." ”

"Mixed heating?" the girl frowned slightly, "Impossible!"

"Alright. At this time, Yu Yao interrupted, "You can make an offer, don't mention it if you don't drink alcohol." ”

The girl thought for a moment and put the painting away, "Don't talk about wine, I won't sell it yet!"

Pu Jie was stunned, "It's the first time I've seen a female drunkard." ”

"What do you say?" the girl glared.

"Is it really not for sale?" asked Yu Yao.

"Yes!"

"It's good that we're an antique shop here, after all. Yu Yao lit a cigarette again, "It's not early, pay attention to safety on the road." ”

When the girl heard this, she turned around and faced Yu Yao, "What do you mean?"

"It's nothing, don't you say it's not going to be sold? ”

"After all, it's an antique shop, you say my paintings aren't old?"

"I didn't say it, it's you thinking too much. ”

"No, since I'm here to sell paintings, you want to collect them, and if you evaluate them, you have to explain it!" the girl gritted her teeth.

Yu Yao smiled, "First, you don't sell anymore, and second, I didn't evaluate your paintings." ”

"Don't be ambiguous, this is the work of Shangguan Zhou in the early Qing Dynasty, of course it is a standard antique!" The girl suddenly slapped the painting on the table of the Eight Immortals, and then sat down.

Pu Jie looked at Yu Yao and didn't speak.

"Because the painting is good, I asked for the price. Yu Yao smiled slightly, "If it's cheap, this painting can also be accepted." But you can't use the price of Shangguan Zhou's works to collect it. ”

"What the hell do you mean?"

"Since you're not selling, let's not talk about it. ”

The girl suddenly said, "Okay, you say, if what you say convinces me, I'll give it to you for free!"

Yu Yao looked at the girl, "This painting can't be painted by you, right?"

The girl was taken aback, "You? you······ What are you talking about?"

Pu Jie suddenly laughed, "So that's what happened!"

Yu Yao waved his hand and glanced at Pu Jie again, "Just kidding." However, this is definitely not Shangguan Zhou's work, and the focus is not on painting, but on making it old. ”

As soon as the connoisseur makes a move, he will know if there is one. The girl groaned slightly, and then stretched out her finger and pointed to the drawing, "Okay! I will do what I say! I will accept it! The painting will be given to you, but you will have to tell me what the problem is!"

"Your paper is not old paper. Yu Yao naturally wouldn't expand it all, so he nodded concisely.

"Go on!" the girl's eyebrows twitched slightly.

"You are a seller of fake paintings, where do you have the right to be arrogant?" Yu Yao suddenly raised his voice, "I'll point it out for you, you should shut up, will the key to identification be told to you?"

If you don't use the old paper of the same era, then you have to make the paper "old".

For a new painting, there are two common methods of distressing, one is called direct dyeing and the other is called fumigation.

As the name suggests, the direct dyeing method is direct dyeing, such as overnight strong tea, such as diluted vinegar, directly applied or sprayed. Of course, there will also be corresponding auxiliary means, not once or twice, it will take time to precipitate, and it is not so simple to complete.

The fumigation method is smoking, and the materials used for ignition are a bit particular, because the smoke from different materials produces different color sensations, and the color of coconut shells is relatively fast.

However, since the direct dyeing method and the fumigation method are used the most, it is difficult to hide from the eyes of the masters.

In this painting, these two methods are not used, but in the process of painting, the back of the paper is dyed at the same time, using special materials, and at the same time, after the painting is completed, the front side is irradiated with ultraviolet rays to accelerate the weathering of the paper and blend in with the background color.

In this way, it is difficult to detect the clues just by looking at the front of the framed painting.

With Yu Yao's eyesight, he can only feel that something is not quite right, and he can't be 100% sure. However, this is a whole painting, since it doesn't feel right, combined with other issues, Yu Yao can be completely sure.

Something else is the issue of seals.

Look at the porcelain first to see the bottom, look at the painting first to see the payment and seal.

The two sides of the seal on this painting are not a big problem with the detail strokes, and the problem lies in the ink.

When the girl heard Yu Yao say this, her shoulders couldn't help but shake slightly, her original liveliness was gone, and she clasped her hands, "I didn't expect a small antique shop to have such a master!"

"There is no size in the antique shop, only the level of the palm!" Yu Yao raised his hand, "You are a girl's family, I don't bully you, you can go! But this painting, I have to stay, you run to my store to call the scene, it is not okay to leave something!"

"I've said it all, and I'm not going to break my word. The girl bit her lip, "I didn't want to come in·······"

"Okay, okay, let's go quickly!" Pu Jie stepped forward at this time and said, "Little beauty, the water in the antique shop is very deep, pay attention in the future." ”

The girl got up slowly and looked at Yu Yao, "There will be a meeting later! I remember you!" With that, she turned around and walked out of the store, never looking back.

Pu Jie waited for her to leave, closed the door of the store again, lowered his head and lit a cigarette, and said at the same time: "I didn't expect that I was still a beautiful drunkard, and this matter was also a mistake." Do you suspect that she is a member of the Academy of Fine Arts' counterfeiting team?"

"Shangguan Zhou Yi is clothed, the characters are brushed, there will be a kind of folk atmosphere in the chic, this painting is imitated in place, but there is a bookish atmosphere, slightly soft, combined with her words and deeds, most of them are painted by her. However, I don't know if she is a student at the Academy of Fine Arts. ”

"You don't have to say it so deeply, I don't understand it. Pu Jie turned around and sat down, "Let's talk about specific technical problems, what's wrong with the aging of this paper?"

"The paper is worn, and the technique is quite high. It doesn't feel right, but it's not 100% certain. I mainly judged it by referring to the ink. Yu Yao responded.

"Oh, what do you say?"

"Actually, I was attracted by the smell of wine just as much as she did, and I smelled it through my nose. ”

"Huh?" Pu Jie said, "This seems to be Zhu Qi's ink." ”

"You've made progress!" Yu Yao nodded.

In ancient times, there are two main types of ink, one is pure cinnabar ink, and the other is vermilion ink.

Pure cinnabar ink is made of cinnabar that is precipitated at the bottom layer when bleaching cinnabar, vermilion, heavy and bright.

The vermilion mud, which is the opposite of pure cinnabar mud, is made by taking the fine cinnabar of the upper layer when bleaching, and then mixing it with silk and vegetable oil.

There are very few materials that can be obtained from this Zhu Qi ink clay, dozens of kilograms of cinnabar, and about one kilogram can be taken, and the processing method is relatively complex, so Zhu Qi ink mud is more expensive than cinnabar ink mud.

The color of Zhu Qi's mud is red and yellow, like ripe orange peel.

"In ancient times, Zhu Qi seal mud was made with refined rapeseed oil or castor oil, but if it was a seal of the Qing Dynasty, there would be no smell at all today. But the two seals on this painting still have a faint smell of rapeseed oil. Yu Yao further explained.

"Good guy!" Pu Jie laughed, "Although the taste of rapeseed oil is a bit special, your nose is also smart enough!"

After laughing, Pu Jie asked again, "There is one more question." Why do you have to keep this imitation of her? It seems a bit of a problem. ”
