Zhang Tianyuan borrowed a small flashlight from his mother's hand, carefully observed the inside of the jade, and clearly found that there were already many small cracks in this piece of jade, although it could not be seen on the surface, but in fact, as long as it was tested with an instrument, it would be known.

He shook his head and looked at the man: "Don't wear jade on your body in the future when you fight or even quarrel, it's too violent, this piece of jade has cracks in its subtleties, if you continue to wear it, it is estimated that after a few years, or more than ten years, it will slowly crack and eventually shatter." ”

"Alas, if I had known about this matter, it wouldn't have been like this. The man took up his jade and fell to the ground.

The jade is very brittle, and the inside of this person's jade has long been full of cracks, so it was broken at that time.

Someone picked up a piece and looked at it casually and exclaimed: "What the little brother said is really right, look at the inside, the cracks are almost full, just like the egg looks good on the outside, but it is broken on the inside." ”

At this time, no one doubted Zhang Tianyuan's words, if what he said before was just talking on paper and reading according to the script, then what he showed at this time was the real appraisal ability, no wonder it would be admirable.

"Boy, you're good, no wonder you didn't want to worship the old man as a teacher, it turns out that you know a lot about jade. Shi Lao Wang couldn't help but say.

When everyone heard this, they were even more surprised, this young man actually refused to worship Emperor Shishi as a teacher, it seems that he really has real materials, not simple, amazing.

Zhang Tianyuan hurriedly explained: "Boss Shi really misunderstood. The reason why I didn't have an apprenticeship was because I still had a business to take care of. It's impossible for Gangzi and I to both learn from you and ignore the company's affairs. ”

"No need to explain, I can accept Xu Gang as an apprentice. It's a great blessing, much better than the apprentice before me. Shi Lao Wang smiled, then looked at the people around him and asked, "Do you have anything else to ask?" If not, I have to talk to my little brother, if there is anything you want to ask, you can just ask, the old man is happy today, and maybe he will answer a question or two for you." ”

Hearing Shi Laowang's words, everyone became excited. I don't know when the road was spreading, and more people poured into the café, and there were even people standing at the door.

Someone asked: "Shi Laowang, this jade has just been bought, do you want to do something to distinguish the authenticity from the fake?"

"You're on the point, but I think it's better to let Brother Xiao Zhang talk about it. "Shi Lao Wang clearly intends to test Zhang Tianyuan.

Zhang Tianyuan thought to himself at this time, he had already said so much anyway. I'm not afraid to say more, it's okay anyway.

So he said: "The younger generation still knows a little about jade, so I just read more books, if what I said is wrong." You still need to understand. ”

"Just say it, it's pretty good. "The people here are also quite convinced by Zhang Tianyuan at this time. The key to Zhang Tianyuan's previous performance can also convince them.

Zhang Tianyuan cleared his throat and said, "Generally speaking." When you buy a new nephrite, the seller will say that it is ancient jade. Since they said so, let's buy it and cook it, and we will know whether what he said is true or false. Of course, I'm only talking about nephrite jade, whether it's ancient jade or new jade, you can boil it, if it's other jade, don't do it, I won't lose money if it is broken. ”

"Hahaha, you can continue. ”

"Why do you want to boil nephrite?"

"That's right, what are you doing?" Liu Hao on the side was also curious.

"This is because many jade dealers have sealed the jade pieces with wax in order to increase the price of jade, and the jade has cracks, and the paraffin wax that flows into the cracks, you can't find the cracks if you don't cook them; second, many counterfeiters use a lot of chemical raw materials, and if you don't cook them, you will hurt your body, but the gains outweigh the losses; third, our teachers have taught us since we were young that we should wash our hands before eating.

"Why, don't you feel at ease if you don't cook it?" someone asked.

"Think about it, if it's really ancient jade, most of it must have been unearthed from the grave, contaminated with bacteria, evil spirits or something, do you dare to wear it directly? Don't you feel panicked when you wear it? Zhang Tianyuan replied.

"I see, little brother, you go on. How do you cook it, is it just like boiling corn on the cob?" someone asked.

"Okay, decided to cook. Note that boiling is not just throwing it in the pot and cooking. Remember, you must not be like the eldest brother said, otherwise the jade will be boiled, but it will be too late to regret it. Zhang Tianyuan said while laughing.

The man's face turned red and said, "Little brother, you can tell me how to cook it, I'll try it when I go back." ”

"My approach is to catch it with a fishing line and hang it on the edge of the pot with chopsticks, hanging in the air. In this way, the temperature of contact with the jade will not be higher than 100 degrees, otherwise it will be thrown in, touch the bottom of the pot, and burn out. In addition, the fire should be boiled over high heat, and the simmer should be kept boiling, that is, the heat of the soup, about 15 minutes. Zhang Tianyuan explained.

"Oh, that's fine, that's easy. But if it's just cooked, the jade must be very hot, how can you take it out?"

"Stupid, of course it's to use cold water to lower the temperature. Someone said rather proudly.

"Don't talk nonsense, let's listen to the little brother!"

"Ahem, some people think that when it is cooked, it is ready to be put out of the pot and served on the plate like a meal? No, don't do that, and don't think about using external forces to cool down, pay attention to wait until the water temperature drops down before taking it out, and don't touch the cold water immediately, otherwise you will become the successor of the ancient gravel!"

"Poof, that buddy, it turns out that you are the successor of the Gravel Gate, hahaha. Liu Hao couldn't help but laugh.

The man blushed and said, "I'm just talking nonsense, talking nonsense." ”

"Of course, it's okay to talk nonsense, but you can't do that. Otherwise, the jade is your own, and if it is destroyed. It's only you who will be sad. Zhang Tianyuan said very seriously.

"We all know what the little brother said. Thank you so much. ”

"Thank you for not having to, I am a junior, it is also a blessing to be able to get your face so appreciated, this year's gambling stone fair, there will definitely be a transaction of ancient jade, but everyone should pay attention, even if it is this kind of right occasion, there are not many real ancient jade. So you must be cautious, don't be fooled and deceived. Zhang Tianyuan reminded.

"Are there a lot of things about ancient jade counterfeiting?" Liu Hao couldn't help but ask: "I have met many people who recommend ancient jade to me, but they don't dare to buy it, first, I am not very familiar with that thing, and second, the price is too expensive, I am afraid of being deceived." ”

"You're doing the right thing, if you don't understand, don't take it lightly. The level of cottages in our country has always been superb. From ancient times to modern times, it is very famous. In China, the history of jade counterfeiting can be traced back to the Song Dynasty. During the Southern Song Dynasty, a large-scale antique jade series has been formed. Counterfeiting ancient jade has become a profession. In the Ming Dynasty, some people made huge profits, and a large number of various forged cultural relics appeared in society.

Ancient jade. The mixing of real and fake is the most difficult aspect of ancient jade to distinguish counterfeits. Ancient jade unearthed from the tomb. It is not necessarily contemporaneous with the deceased. Therefore, it is necessary to understand the basic methods of jade forgery, and pay attention to distinguishing the counterfeit when identifying jade. Jade forgery. Generally, the jade of the time is used to imitate the color of ancient jade. Zhang Tianyuan patted Liu Hao's shoulder and appreciated.

"By the way, I've always heard you talk about Qinse, but what is this Qinse?" Li Xiao didn't know anything about Gu Yu, so it was reasonable to ask this kind of question.

Xu Gang couldn't bear the loneliness at this time, and hurriedly said: "The jade buried in the ground, after a certain period of time, will be eroded by other substances, which will produce some color changes, and jade experts call it 'Qin color'." ”

"Oh, I see. ”

"In fact, with jade forgery, the most important thing is to work the color, many people who play jade look at the jade, the first thing to see is the color. Zhang Tianyuan added.

"Can this color be faked?"

"The main method of counterfeiting jade is simmering: the jade is grilled with fire and turned gray-white, imitating the color of "chicken bone white"; There are fine cracks of firing. Sheep jade: high-quality jade is implanted into a live leg of lamb, and taken out after a few years to produce a blood-colored texture, imitating ancient jade. Dog jade: The jade is placed in the belly of a freshly killed dog, and after a few years, it is taken out to produce earth flower markings. Meiyu: The poor quality jade, boiled with black plum water, and then colored with the oil extraction method, pretending to be "puddle ancient", the rest of the wind jade, knock rust, oil extraction, old oil, dead jade, loess rust method, hematopoietic Qin method, black spot method and other methods, you can read more books after you go back, understand for yourself, I will not say much here. Zhang Tianyuan said.

"That color can be faked, how should we judge the authenticity of an ancient jade, it is impossible to cook it directly on the spot, right?"

"In fact, there are some very good methods, as long as you understand common sense, even if you don't understand jade, you can identify it. If a jade artifact is found to be older than the one recorded in ancient books, it may be a counterfeit. For example, there is a detailed description of the shape, use, and use of jade ritual vessels in the book "Zhou Li", and the jade belt system described in the classics of the Tang Dynasty records the era, shape, and specifications of some jade objects, which everyone can look back at. Zhang Tianyuan smiled and said: "In fact, it is easy to counterfeit, but the art and style of jade carving are difficult to counterfeit, if you understand these, it will be easier to judge." ”

"What do you mean?"

"Jade counterfeiting often focuses on shape and color, rather than craftsmanship and artistic style, or is difficult to imitate. If the craftsmanship and artistic style of a piece of jade do not correspond to the stated era, it may be a counterfeit. For example, the Neolithic jade cutting process was rough, the thickness was uneven, and the holes had traces of drilling, and the edges and corners were not distinct, while those made with modern tools were difficult to imitate. Zhang Tianyuan replied.

"I see, I kind of understand. ”

At this time, Mu Yi, who was sitting there, couldn't help but say: "Brother Zhang must be right when he said this, I still remember an incident I encountered before, someone recommended a jade Ruyi to me, the workmanship and color are very perfect, I almost wanted to buy it at the time, but then I heard the man say a word, and immediately dispelled this idea, that person actually said that this is the jade Ruyi of the Han Dynasty." ”

"Is there anything wrong with that?"

"Of course it's wrong, Jade Ruyi began in the Wei and Jin dynasties and flourished in the Ming and Qing dynasties. How could there be a jade Ruyi in the Han Dynasty, just for this reason, I don't have to look at his thing, I can directly judge that the thing is fake. ”

"That's right, the mother boss did this thing well, if this is changed by some people, probably even if there is no jade Ruyi in the Han Dynasty, they will be obsessed with money to buy it, so in the end, this is still a matter of mentality, you must know how to be willing, you must not be greedy, and you must not be impetuous, otherwise you will be the one who suffers and is deceived. At this time, Shi Lao Wang also smiled and said.

"Okay, let's be here today, you probably have your own things, I also have something to say with Brother Xiao Zhang, if there is really anything you want to ask, you can leave a contact information for each other, and it will be convenient to contact each other in the future, they are all people in the circle, and it is easy to do things if you have more friends." ”

Shi Lao Wang saw that Zhang Tianyuan was talking dry at this time, and even if it was an air-conditioned room, he was sweating, and he knew that Zhang Tianyuan was a little tired, and it was close to dinner at this time, so it was time to eat, so he said. (To be continued......)
