Chapter 775 Da Vinci imitation painting? (continued)

Hearing this, Wu Ke felt a little strange, so he asked: "I saw a magazine last time, which said that oil paintings were authenticated by carbon 14, and the results have a high reference value. Boss, why don't you do it?" What about an identification?"

Carbon-14 is a radioactive isotope of carbon that was first discovered in 1940.It is produced by the impact of cosmic rays on nitrogen atoms in the air. Its half-life is about 5730 years. The decay method is beta decay, and carbon-14 atoms are converted into nitrogen atoms.

Since the ratio of each isotope of carbon in nature has always been stable, and carbon is one of the elements of organic matter, with a half-life of 5730 years, people can estimate the approximate age of an ancient object by measuring its carbon-14 content.This method is called carbon dating.Carbon 141 identification is widely used in current archaeology and identification.

Nan Nan smiled slightly and said, "It's not that I don't want to do it, but the results given by carbon 14 are not very authoritative in any case. My painting was actually found in a trash can. Yes, in this case, even if I use carbon-14 for identification, the results I give are completely useless."

The identification of carbon 14 is limited, because a large amount of carbon elements produced by artificial nuclear explosions have a great impact on the atmosphere, and since the industrial revolution in the 18th century, the common carbon element C in the atmosphere has greatly increased, which has a great impact on the ratio of carbon elements. The BP starting point in internationally recognized carbon-14 dating is 1950.

Generally speaking, the identified samples must not be contaminated. If early or late carbon is accidentally mixed in, the measured results will definitely be very different from what we want.

Therefore, it is unreliable to draw conclusions without strictly explaining the sampling process. In archaeological excavations, the results of carbon [-] determination are still a reference, not a decisive one.

Archeology is still like this, let's look at calligraphy and painting, can it meet the conditions for carbon fourteen detection?
First of all, what era and creature is the paper used for calligraphy and painting?How many years has the finished product been aged?In what way will it be released?Is there air convection under aging conditions?Is pollution introduced during the use of calligraphers and painters?What biomaterials are used for pigment inks, and the above questions?

How is the work preserved after creation?How does framing affect the work?Did the framing process introduce materials of different ages?Is there any liquid used in the framing process, such as water, etc.?How to collect and display works?How is the air convection in collection and exhibition?And so on, there are many complicating factors.

This also makes, even if the works of calligraphy and painting can be identified by carbon 14, it can generally only serve as a dispensable reference value.

In fact, any detection should be based on substances. To detect the age of a sample, it is necessary to find a substance that is completely linearly related to the age change. In the field of calligraphy and painting, it is difficult to find such markers.

All substances in calligraphy and painting works have all started from different starting points and have experienced different transmission and pollution to the present. It is difficult to measure the content of any substance without the scientific explanation of the sampling process, not just the determination of carbon fourteen. in this way.

Since the portrait of a young girl in front of me was found in a trash can, the oil paint on it must be more or less polluted. In this case, carbon 14 will definitely not work.

After listening to Nan Nancai's explanation, Chu Chen and Wu Ke finally understood why Nan Nancai didn't go for an appraisal, but they were even more surprised that the painting was picked up from a trash can, which is unavoidable. Is it too ridiculous?

Seeing the surprised expressions of the two, Nan Nancai was also very proud of her good luck.

He smiled and said: "It's a coincidence. Last year, a friend of mine was discharged from the hospital. I went to visit his house. When I left, I was greedy for the distance, so I walked from an alley to the parking lot. , I saw this painting in the dumpster in the alley."

"At that time, I thought it was just a replica, but when I walked over to see it, I found that it was actually a real oil painting, and apart from some dirt on the frame, the canvas was not affected much, so I put the It took it back."

After listening to Nan Nancai's narration, Chu Chen and Wu Ke finally understood why the picture frame looked so dilapidated.But even so, the two of them still found it inconceivable that who the hell was so rich that he could throw something worth hundreds of thousands of euros into the trash can.

Chu Chen was a little skeptical. This might be Nan Nan's deliberate rhetoric, which is not the case.

"Boss, why don't you change the picture frame?" Wu Ke frowned and said, she was a little bit obsessed with cleanliness, and when she heard that the picture came out of the trash can, she suddenly felt a little nervous. Tired, if it were her, she would definitely not want such a thing.

After hearing the words, Nan Nan understood Wu Ke's thoughts. He said with a smile: "Although the frame is a little old, it is still the original frame of the [-]th century, and I have had someone clean it completely. There's going to be something wrong."

Hearing what he said, Wu Ke didn't take it seriously. For people with cleanliness, this kind of pimple is definitely not easy to get rid of.

Chu Chen didn't care about this at all. Now he is most concerned about one issue. If this painting was thrown into the trash by mistake, what about the ownership?So, he asked, "Boss Difficult, can you guarantee that the original owner didn't accidentally discard it?"

Nan Nan said with a smile: "Don't worry about this, I also have contacts at the local police station. If it was lost by mistake, then the original owner can't say that he hasn't called the police all the time, right? No one reported the case. Moreover, if you agree to the exchange, we can sign a contract, and if there are problems in the future, all your losses will be borne by me."

In fact, Nan Nan likes oil paintings more, and he also appreciates this painting. Originally, he didn't want to show this painting, but he liked Chu Chen's arhat bracelet so much, and Chu Chen's eyesight Extremely high, he felt that if he didn't come up with a heavyweight work, it would definitely be impossible to impress Chu Chen's heart.

Just like what Chu Chen said just now, since he can't have both, he can only choose what he wants in his heart.

After listening to Nan Nancai's words, Chu Chen pondered for a while. In fact, if he hadn't discovered by accident after using the ability while Nancai was speaking, he would really not be interested in such imitations. But now it is unexpectedly discovered that even if there may be disputes in the future, he still wants to take down the painting.

Of course, since Nan Nan just said that, the possibility of disputes is very small, and if there is a dispute, at most he can return the painting in front of him to someone else.

"I didn't expect that I still couldn't resist the temptation in my heart!"

Chu Chen laughed at himself, and then said with a smile: "Since you are so sincere, boss, what reason do I have to object to this matter?"

Nan Nan heard the answer she wanted, and she couldn't help but smile like a flower.

However, Chu Chen immediately said: "Boss Difficult, I don't know much about the market value of oil paintings, and I'm not very good at judging the value of your imitation work!"

What Chu Chen said was true. He was not too interested in oil paintings. He knew the price of oil paintings from the "Athens School". He didn't know much about the imitation painting market of famous artists.

But Chu Chen had the price given by the supernatural power as a reference, so if Nan Nancai wanted to fool Chu Chen, it would be a big mistake.

Nan Nan just heard what Chu Chen said, not only did he not have the idea of ​​trying to fool Chu Chen, but he secretly scolded Chu Chen as a "little fox". This was because he felt that Chu Chen might be using this matter as a test If he is not satisfied with the price offered, the business will definitely fail.

He said with a smile: "Mr. Chu, don't worry about this. I have been in business for so many years, and I still know the four words of honesty and integrity. Besides, if the price is not satisfactory, we can also discuss it! How about it, the previous appraiser gave me the price." My reference price is 45 euros, since I got it for nothing, I will give you some profit, 40 euros, what do you think?"

What Chu Chen said just now is actually a way of counter-offering. Between the truth and the truth, Nan Nan did not dare to ask too much. Of course, the matter did meet certain expectations, but it was only after hearing Nan Nan that he made the offer. He curled his lips secretly and cursed "profiteer" secretly.

In other words, if this painting is genuine, even if Nan Nan added two zeros, it would be the least of it, but if you change from the real to the imitation, it is really a jumping price, the price given by the ability, in fact Only 30 euros.If it was exchanged at the price given by the ability, Nan Nan would have to pay Chu Chen.

Of course, the price given by the ability is actually relatively low, and some subjective factors must be added to the transaction in the market, but even if this price increase is added, Chu Chen feels that the price of the painting in front of him is also the same as the price of the painting. The value of his three things is just the same, not to mention that Nan Nan is still the one who begs for help.

So, the next two people had a fight without gunpowder, and it was Nan Nan who was defeated in the end. In addition to the oil painting in front of him, he also gave Chu Chen some discounts and used them on the table. The two pieces of porcelain brought just now are on top of the nine-eyed dzi bead that Chu Chen had taken a fancy to earlier.

After the transaction was completed, Nan Nancai also let out a long sigh of relief. He was quite satisfied with the result. Not only did he get something he was satisfied with, but he also made a lot of money, but what he paid was just a painting. Da Vinci's imitation.

But Nan Nan didn't know that it was his seemingly profitable decision that made him lose a chance to make a fortune. If he knew the truth, he would probably regret it.
