When Chu Chen said this, Wu Ke interrupted with a smile: "ah Chen, it's not right for you to say that. But I heard the teacher who taught me Guqin before say that the reason why there were broken lines when Guqin was made in the Republic of China or some traditional crafts was because they used poor gray tires and used tile ash. Of course, there were broken lines."

Tile ashes can be found everywhere. The reason why it is used in combination with raw lacquer as the grey body is completely due to the production cost. Therefore, many folk Guqin are made with this kind of grey body. Especially after the Ming Dynasty, tile ash appeared gradually, and it was even more common in the Qing Dynasty. Its characteristic is that the sound is easy to loosen. Because the paint ash is easy to fall off, collectors do not like this kind of Qin.

Chuchen said with a smile: "what you said is true, but I mean that the causes of the broken lines are complex, which are mostly related to the lacquer processing in the production process and the later preservation environment. Therefore, we should make a detailed analysis. We can't say that this Qin is very old when we mention the broken turtle lines. You know, the broken lines on some ancient Qin are still forged."

"Wen Duan or fake?" When Wu Ke heard about it, he thought it was incredible.

Chuchen said with a smile: "as long as there are interests, of course, some people will try to find a way, and the fake broken lines have appeared in ancient times. As for the methods, there are still many, such as baking with a fierce fire, and then stimulating it with ice and snow to crack it; or using protein to infiltrate into the ash to brush paint, and then steaming and air drying; or using gypsum to bake the ash bottom, and some even using knives It's a moment. "

"However, just like the identification of antiques, fake is fake. After careful observation, there is a big difference between the true and false broken lines. The true broken lines are smooth in shape, the tail of the lines disappears naturally, and the peak of the lines is like a sword blade. However, the false broken lines will inevitably be unnatural and flawed through the process of hot and cold catalysis or knife carving."

After listening to Chu Chen's explanation, Wu Ke hurriedly came forward to observe, and found that the above lines should not be caused by human beings, which made her very excited, and said: "ah Chen, these lines should be formed naturally, so the production time of this Guqin should not be short?"

Chu Chen nodded: "short is not short, but it's not easy to judge the specific production time of this Qin by the pattern cut. Generally speaking, although the tortoise pattern cut is the most valuable, according to the records, it was formed in an ancient time. As for the ancient time, it's not very clear."

"That's it Wu Ke was a little disappointed when she heard that Yan. She looked at the piano face again and found that there were other patterns on both sides. She raised her spirits again, pointed to the pattern and asked, "ah Chen, is this ox hair?"

"Yes, it's really ox hair fracture, but it was formed in the middle ages. In fact, the oldest pattern fracture should be this one!" With that, Chu Chen pointed to a broken line on the head of the instrument.

Wu Ke saw that the broken pattern was round and clustered like a plum blossom ring. He was surprised and said, "this is the broken plum blossom."

Chu Chen nodded and said, "yes, it's Meihua Duan. Generally speaking, Meihua Duan is the oldest. It's said in ancient books that Meihua Duan is not born for thousands of years. Therefore, when this Qin is made, it must be at least more than a thousand years old."

Wu Ke seemed a little excited and said: "that is to say, this Guqin must have been made in the Northern Song Dynasty at the latest, and it is likely to be a tangqin!"

Chuchen said with a smile, "it's possible to say it's tangqin, but why do you have to think it's tangqin?"

"That's nonsense. Tang Qin is worth a lot of money." Wu Ke naturally said.

The ancients often talked about a person's talent and cultivation with Qin, chess, calligraphy and painting, and Qin is the first of the four arts, and also the first of the eight tones of traditional music in China. Because the ancients paid Guqin's cultural status, the collection of Guqin now is only a minority, but the price is not low.

Don't mention Tang Qin or song Qin. As early as 1998, an imperial dongtianxianlai Qin in the Ming Dynasty was valued at 1.2 million to 1.5 million, which shows the value of a good Guqin.

As for tangqin, Chu Chen has never heard of it so far, but he thinks that if it is a Guqin with good sound quality and some fame, the price will not be cheap.

One year later, in 2003, Wang Shixiang's old collection of "Da Sheng Yi Yin" Qin of the Tang Dynasty set a world record for Guqin auction at that time with 8.91 million yuan. Nine years later, when this "Da Sheng Yi Yin" Qin appeared again, it was finally sold at 115 million yuan, and the price rose nearly 12 times.

Moreover, 115 million yuan is not the highest auction record of Guqin. A Song Shi Jian Yi Guqin from the Northern Song Dynasty sold for 136 million yuan in 2010, creating a world auction record for musical instruments.

At that time, Chu Chen also discussed this matter with his friends. Everyone thought that the price of more than 100 million yuan was a relatively low price. Why do you say that?

You know, this and "songshijianyi" Qin are the imperial Qin of Huizong in the Northern Song Dynasty. Compared with the market of calligraphy and painting in China at that time, Qi Baishi's calligraphy and painting has been able to sell 400 million yuan, that is, Zeng Gong, one of the eight famous artists in the Tang and Song Dynasties, who also sold 109 million yuan in 2009.

Do you think the value of a character written by Zeng Gong can be compared with that of a Qin used by the emperor at that time? So from this point of view, we all think that the price of Guqin is cheaper. As for the auction record, everyone doesn't think much of it. If Chu Chen's piano appears in the auction market now, let alone 136 million yuan, they won't be surprised if it sold for 1.36 billion yuan.Of course, this is later, not to mention.

Chuchen listened to what Wu Ke said and said with a smile: "you are really a little money fan!"

"I'm a money fan, you have a problem!" Wu Ke makes a face at chuchen.

Chuchen said with a smile, "of course I don't have any opinions. The higher its value is, the happier I am. However, why do you just regard it as tangqin? Can't it last longer?"

"More time?" Wu Ke was a little surprised and said, "do you mean that this Qin was made in the northern and Southern Dynasties or the Jin Dynasty? As for the Han Dynasty and the Three Kingdoms, it should not be possible. What kind of wood can be preserved for such a long time? Besides, the wood that has been stored for such a long time must be crisp. How can this piano be so heavy? "

As she said that, she weighed the weight of the Qin, which was really heavy. She knocked on the surface of the Qin, and found that from the sound point of view, there was no feeling of looseness. This not only made her feel that the production age of the Qin could not be further than that of the Tang Dynasty, but also doubted whether it was a Tang Dynasty Qin.

Chu Chen said: "judging from the material of this Qin, it's really not as old as it used to be, but the ancient materials are richer than ours. Who knows how they deal with it. Maybe the makers at that time found a way to keep the piano for a long time? "
