Chapter 160 Falsification Law

"yes, what's the use of that?"

Fang Ming's brows also furrowed, under the ever-changing high technology, it was definitely not surprising that people could do this, but in that case, why did Zhou Yafang emphasize this? He couldn't figure it out.

"Of course it works."

Zhou Yafang looked at Fang Ming and Jiang Wen, and then said: "Fang Ming, you have just mentioned that in the counterfeiting of copper coins, there is a kind of piecing, because the copper coins that are counterfeited in this way have cracks no matter how they are handled, but they can't be seen on the surface, and experienced people can naturally identify whether a copper coin is made in this way through their voices." ”

Fang Ming and Jiang Wen couldn't stop nodding, this truth is not difficult to understand, the way of spelling is simply to put together two parts that did not belong to the same copper coin, but the spelling is the spelling, no matter how you can see it on the surface, but there are still seams inside, so that the sound made when you hit it will be different, and experienced people can naturally hear it as soon as they hear it.

"What about the taste? What does this mean? ”

Among the sounds and tastes mentioned by Zhou Yafang, Fang Ming was most curious about taste.

"Copper coins have a smell, this is certain, what we mean by taste, of course, does not mean that the copper coins pass through the hands of the pork sellers so that they leave the oily smell of pork, but refers to the natural formation of copper coins in the process of circulation/one/book/reading/novel ybdu. For example, if a copper coin is buried in the soil for a long time, it will have an earthy smell peculiar to earth. As for the fake ancient money, the way of making it is nothing more than chemical industry, etc., so it will have a special taste, for example, if it is made of fake rust by paint and other methods, it will definitely have the strange smell of paint; If rust grows after long-term soaking with sulfuric acid, acetic acid, etc., in addition to being easy to fall off, it often leaves the taste of acidic liquid...... Therefore, taste also plays a very important role in the identification of copper coins, of course, it is not easy to do this. ”

"Hah! Isn't that the same as 'smelling a woman'? ”

Fang Ming's words naturally attracted a burst of eyes from Zhou Yafang and Jiang Wen, Fang Ming spread his hands and said, "What I said is the truth, besides, this is not the first thing I said, it is the name of a movie." ”

"Sister Avon, I heard you say so much just now, it seems that there are many ways to make fake copper coins."

Jiang Wen is still in a situation where she is still half-aware of antiques, and it is precisely because of this that she is full of interest.

"It's a technical job."

Because of her grandfather's relationship, Zhou Yafang once knew a master of making bronze coins when she was a teenager, so she was very familiar with the doorway. At this time, Fang Ming and Jiang Wen wanted to know that she would not hide her secrets.

"Most of the bronze coins circulating in the market are unearthed, that is, they are buried in the ground and then dug up, and in the long years, copper coins often form 'pit rust', and such rust colors are often green, yellow, red, white, etc.; If it is a bronze coin that has been played with for many years, because the oil and sweat on people's hands seep in during the process of playing, it will form brown or yellow-brown, which is the so-called 'heirloom ancient'. As I said before, rust is an important feature of bronze coins, so some people have come up with many ways to get this rust color. ”

Fang Ming scratched his head, he didn't expect that just one rust color could be divided into "raw pit rust" and "heirloom ancient", but this name was very apt and full of poetry.

"Is there any way to make 'Rust in Pits' and 'Heirlooms'?"

Although because of his ability, all the means of falsification did not work in front of him, but Fang Ming was still curious about this, he knew very little about these methods, and such things, except for people with family roots like Zhou Yafang, could only be accumulated by time and countless holes, Fang Ming did not have such conditions, so he didn't have much knowledge in this area at all.

At the same time, Jiang Wen's ears were also pricked up, she didn't want to miss any of the words Zhou Yafang said.

"Generally speaking, the most common occurrence of pit rust is green, because copper has been buried in the ground for a long time, and it will naturally grow green, which is often called patina. Now there are several common ways to do counterfeiting: first, bury the copper coin in the ground, two or three or three or five years later, it will be 'grown' full of patina; second, the use of hydrochloric acid or acetic acid, first soak the copper coin inside, and then bury it in the ground or put it in a humid place, so that it only takes a year and a half to appear patina; third, use glue to mix green powder, and with the progress of science and technology, this point is more and more used, because the glue is most afraid of hot water boiling, But now I am not afraid, in addition, there are rosin and so on. As for the red rust and yellow rust, they are basically in the same way as above, but with a slight adaptation."

"Isn't it? Bury copper coins in the ground for three or five years? Is there really such a thing? That's a little too long, right? ”

Fang Ming was stunned, three or five years is not three or five days, waiting for such a long time is not something ordinary people can do.

Zhou Yafang nodded and said: "Don't say it's three or five years, even if it's ten years, if you add some acid, hard rust will be formed, that is, rust that is not easy to fall off, which is the closest to natural pit rust." ”

"Huh? No way? Decade? ”

Jiang Wen also widened her eyes, if she was eighty years old for a lifetime, ten years would already be one-eighth!

"There's nothing strange about that, you know, the value of antiques is very high, and compared to that huge profit, ten years is not something that can't wait."

Fang Ming and Jiang Wen nodded lightly, if it was the top antiques, it would be millions at every turn, so what could it not take ten years to exchange for it? What's more important is that this can be mass-produced, not much, just making ten pieces at a time is already amazing, that's a big business of hundreds of millions!

"Sister Avon, what about the ancient heirlooms? Just now you said that the brown or black-brown color is produced by long-term play, which is not easy to make, right? ”

Shaking her head, Zhou Yafang said: "The wisdom of the people is infinite, especially under the stimulus of making money. Although it is difficult to pass down the rust color of the ancient times, people have also come up with many methods, the most important and the most effective of which is to burn the fake copper coins with fire, and when they are cooled, the copper coins will turn black. Or if you soak the copper coin in hydrochloric acid or sulfuric acid for one to two days, it will turn black after taking it out. ”

"Huh? Just buried in the ground? After three or five years, or ten or eight years, it will form a hand-me-down? ”

Zhou Yafang glared at Fang Ming and said, "What are you making such a fuss about, although it is true that you are burying it in the ground, you must wrap it tightly with a cloth belt before burying it, or it will not work well." ”

At the beginning, Fang Ming listened to it with relish, but slowly he heard a different taste from Zhou Yafang's words.

"Sister Avon, why do I think there is a message in your words, that is, the current fraud has passed quite well, and ordinary people have no way to distinguish it?"

Zhou Yafang does have this meaning, and this is also a fact, now the skills of counterfeiters are getting higher and higher, especially the addition of many high-tech magic forces makes counterfeiting more and more real and more difficult to distinguish. She still remembered that a year ago, she encountered a few copper coins with Wanli back dragon patterns, with the rust color of Weishigu on them, which was not much different from the real one, if she was not careful and careful, she would almost be fooled!

"It's true, the current level of counterfeiting is too high, which also requires us to be careful when identifying antiques, and accumulate a variety of experience, specifically to use a variety of identification methods, such as the sound, color, taste, etc.

The antique industry seems to be just playing with antiques every day, selling bookbags and the like, and then suddenly a broken bowl can be sold for tens of millions and the like, but in fact it is not that simple, high profits and high risks at the same time. Ordinary people can't play it, in fact, in this industry, there are often stories of someone who went bankrupt because of his eyes.

"Well, we get it."

Fang Ming and Jiang Wen both understood that Zhou Yafang was taking the opportunity to warn her to deal with it carefully.

"Anyway, be careful!"

Zhou Yafang was indeed warning Fang Ming and Jiang Wen, after all, their time in the industry was too short, especially after Fang Ming was picking up leaks together, they had never encountered setbacks at all, if they were careless once, maybe they would not have a chance to turn over in this life.

Of course, she also knew better whether her words would have an effect in the end, and how much Fang Ming and Jiang Wen listened to was beyond her control, so she could only resign herself to fate.

The number of people in the store slowly increased again, this time Jiang Wen couldn't just say hello, so Fang Ming and Zhou Yafang set out together, and after half an hour, the three of them all smiled bitterly - there were no antiques to sell in the store! Of course, except for the few pieces of doucai left by Fang Ming and Zhou Yafang as the treasures of the town store.

"Sister Avon, we have to close the store."

Fang Ming touched his nose, the situation in front of him was really unexpected, the business was too good, more than thirty antiques in the store were sold in less than half a day, and now in the store, except for a few treasures of the town store, there were only antiques borrowed from Qian Fang, but they couldn't be sold.

"Well, yes, I can only close the store door temporarily."

Zhou Yafang's brows were tightly locked, and the business was far better than she imagined, it was rare to be able to sell an antique a day or even a few days, but now there was such a "crazy" state, it was incredible!
