When Chu Chen returned to the shop, Zhou Wenping saw the jade cong in his hand and asked strangely: "Why does the jade cong in your hand look like something from Liangzhu culture?" Chu Chen Hehehe said with a smile: "Brother Zhou, you are right, but I haven't looked carefully yet. I just thought that this jade cong is more likely to be from the Liangzhu culture." "Really?" I heard Chu Chen say this. , Zhou Wenping was really pleasantly surprised. The Liangzhu Culture is a late Neolithic culture represented by black pottery and polished jade around the Taihu Lake Basin. It dates back 5300-4000 years. The most famous one is its jade, which is characterized by dense, detailed and harmonious carvings. Known for neatness. Among the typical Liangzhu jade wares is the jade cong. Because of its exquisite decoration, important historical value, and great artistic charm, it has been sought after by jade enthusiasts since ancient times. He began to imitate the shape of Liangzhu jade congs, which shows his great influence. Because of its great influence and the extremely high price of Liangzhu jade, there are constant imitations on the market. It is not an exaggeration to say that it is overrun. Liangzhu jade is sold everywhere, in shops and on street stalls. From hundreds of thousands to tens of dollars, there are so many kinds that it¡¯s dizzying to see. It is precisely because the Liangzhu jade market is so chaotic that Zhu jade enthusiasts often want to collect but dare not collect. The main reason is because they cannot judge the authenticity of these jade bis. This is actually the most important reason why Zhou Jude would sell the truth to Chu Chen as a fake, and why Zhou Wenping is so excited now. At the same time, Lao Wu happened to come out from behind the store and saw Zhou Wenping's excited look. He couldn't help feeling a little strange and asked, "What's wrong with you?" Chu Chen raised the thing in his hand. He smiled and said: "Let's go upstairs and talk about it later!" The three of them sat down. Lao Wu looked at the jade cong that Chu Chen placed on the table, his expression looked a little incredible, and said: "Such a big jade cong, don't tell me it is a Liangzhu jade cong!" Chu Chen said with a smile: "I I think it¡¯s very likely. As for whether it¡¯s true or not, I¡¯ll wait until I see it first before I tell you.¡± Liangzhu jade cong is carved from nephrite and looks square on the outside and round on the inside. . The fine carving technique of negative lines on its surface has reached a level that is almost unmatched by later generations. Not only that, Liangzhu jade cong also prides itself on its large size, which shows its unique charm. Like the jade cong in Chu Chen's hand. The length is estimated to be around 14 to 15 centimeters by visual inspection. Even if it is not as tall as the 17 centimeters of Liangzhu Jade Cong King, it is still quite rare and rare. Of course, bigness is another aspect. If it is just big, it will not attract the attention of fans. In addition to those exquisite and complicated decorations, the square columnar jade cong has vertical grooves in the middle of the four sides. The two sides of the groove are basically equidistant, and the error Around 1 mm. The upper and lower spacing of each section is also almost exactly equal. And the composition of the jade Cong animal mask pattern is basically the same. There is a half animal face on the corner of each face, and the half animal face on the adjacent side corner forms a complete animal face. This combination makes the originally dull animal face more vivid and varied. ??For example, the jade cong in Chu Chen¡¯s hand has a composite image of a god, human and animal face engraved on the top and bottom of the four straight grooves. It is carved using line relief combined with fine line engraving. On the rectangular convex surface divided into two sections to form a square ruler, with the corner as the central axis, it unfolds to both sides. Each two sections is carved with a set of simplified symbolic facial patterns of gods, humans and animals. The four corners are the same and symmetrical. One of the simplified mythical animal sections is also decorated with bird patterns. And each pattern is decorated with cloud and thunder patterns. These complicated totem patterns are composed of lines as thin as hair. After Chu Chen admired it, he couldn't help but let out a sound of admiration. This is actually a problem that has been plaguing many experts and scholars to this day, because people really can't imagine how to deal with jade materials that are harder than ordinary rocks and various metals in the Liangzhu period when there was neither bronze nor steel. Process it to make it into a jade cong with such exquisite and intricate patterns? In addition, how did people at that time control the error of jade congs so accurately? Especially in the relatively primitive society four or five thousand years ago, Chu Chen found it very incredible when he thought about it. It took Chu Chen more than twenty minutes to carefully look at all the features of this jade cong with the help of a magnifying glass. Although judging from Bao Jue's reaction, he guessed that this was probably a piece of jade cong. It was an authentic product, but when he was able to confirm that it was truly an authentic product, he couldn't help but show excitement. Zhou Wenping and Lao Wu saw Chu Chen's expression and immediately understood the meaning, and asked in surprise: "Is this really true?" "Yes, you will know just by looking at it!" Chu Chen said with a smile. Zhou WenpingWhen Lao Wu heard this, he quickly took turns observing. At this moment, Gu Jianming came here to take a rest. Seeing that Chu Chen was there, he smiled and said hello, and then asked: "Boss, when did you come back?" "Yesterday afternoon!" Chu Chen replied with a smile. After saying a few words, he asked: "How are you doing at home recently? What are your living habits?" Gu Jianming said happily: "It's pretty good, but it's a little drier here than in the south. The children were a little uncomfortable at first, but they've been used to it for the past two days. "I'm getting used to it." "That's good!" Chu Chen said happily: "By the way, how is the progress of the jade jewelry carving now?" Gu Jianming replied: "It will be enough by the opening day! How about we go take a look at the works we carved now?" Chu Chen agreed, "Okay, but I'll go after Brother Zhou and the others have finished reading." "Okay!" Gu Jianming nodded. Then he looked at Zhou Wenping and the others, and found that the things in Zhou Wenping's hands were a bit familiar, so he asked curiously: "What are Xiao Zhou and the others looking at!" "It's a piece of Liangzhu jade I just got. "What, Liangzhu jade cong?" Gu Jianming was extremely surprised when he heard this and took a closer look. He didn't expect that it was the Liangzhu jade cong that he had always wanted to appreciate and study. What a surprise. Seeing Gu Jianming's expression, Chu Chen asked a little strangely: "Master Gu, are you also interested in Liangzhu Jade Sect?" Gu Jianming said excitedly: "Of course, you know, Liangzhu In the decoration of Nagisa jade, even within a one millimeter wide negative line, there are more than three clearly targeted negative lines. This kind of carving technology is difficult to achieve even with the help of modern processing machines. Achieved. Such superb carving craftsmanship is of great reference value to those of us in the industry." Hearing what Gu Jianming said, Chu Chen smiled and said, "Okay, I won't be too busy after a while. I can keep this jade cong in the store for you to study for a while. "Thank you! Thank you!" Gu Jianming was very excited when he heard Chu Chen say this, and he thanked Chu Chen repeatedly. After all three of them had finished looking at the jade cong, Lao Wu couldn't help but sigh: "The Liangzhu jade cong is indeed well-deserved. If there weren't so many fakes and the price wasn't so expensive, I would really want to go there too." Buy one." Zhou Wenping smiled and said, "Come on, good products are not cheap, and good products are not cheap. Do you think such exquisite Liangzhu jade can be cheap?" Gu Jianming next to him laughed. , and then said to Chu Chen: "Boss, can you introduce to me the key points of identification of Liangzhu jades? I will go to Panjiayuan next door to try my luck someday." Chu Chen said: "I can introduce it, but One thing I want to remind you is that you must not be careless and impulsive when buying antiques, otherwise it will be easy to get blinded. " Gu Jianming nodded and said: "I know this, anyway, if I really want to buy it, I will definitely look at it. After all, Gu Jianming is a skilled craftsman, and he can still see the artistic conception expressed in jade articles, while fakes are often copied mechanically. Unless they are high imitations, they are really difficult to deceive. Guo Jianming. Chu Chen said with a smile: "Okay, let me tell you some of the characteristics of this Liangzhu jade now." As he said, he picked up the jade cong and explained: "First of all, the appraisal of Liangzhu jade must be careful. Distinguish jade quality and color. There are many kinds of materials used in Liangzhu ancient jade, the most important of which are nephrite from tremolite to actinolite series, as well as fluorite, pyrophyllite, chalcedony, turquoise and other jade. " "As for the characteristics of these jade stones, I will bring you a book to read tomorrow. You can understand it more easily by referring to the color pictures above. Speaking of jade quality, let's talk about Qinse, most of which are Liangzhu jade articles. After receiving the Qin color, it becomes chicken bone white. " Speaking of this, Chu Chen pointed to the Qin color on the jade cong and said: "But just like the white color of the chicken bone on this jade cong, there is no pure ancient Liangzhu jade. Chicken bone white, jade whitening formed in the natural environment, is formed due to the gradual loss of crystal water inside the tremolite. It generally undergoes a gradual process of reddening, devitrification, and whitening. This is the most basic way to identify Liangzhu jade. "In addition, the processing method of Liangzhu jade is very advanced and can produce excellent polishing effects. Coupled with the combined influence of the burial environment for more than 4,000 years, it will eventually form a glass light effect, which can be seen under high-power magnification. Irregular micro-grinding marks can be seen, which is a feature that cannot be imitated by modern power tool processing.¡± ¡°Except for the above.As for the characteristics mentioned, there are two most important characteristics of real Liangzhu jade. These two points are the inscribed lines you just mentioned, and the charm in them. " After Chu Chen took a sip of tea, he continued: "At the time of the Liangzhu Culture, it was definitely not possible to have so many advanced automatic tools like now. Therefore, these exquisite jades definitely could not be completed in a short time. , coupled with the special functions of jade at that time, it contains the author's hard work and solemn charm. " " This is something that experienced experts or skilled craftsmen like you can generally feel. " (To be continued, please search Piaotian Literature, the novels will be better and updated faster!
