A "Tongzhi Cai" high-foot plate like the middle-aged man's, even if it is a set of eight pieces, the highest price is only about 10,000. Feng Zhengjian is eager for the middle-aged man to agree to his proposal. The middle-aged man is just a fan of the authorities, not really stupid. Seeing what Feng Zhengjian said, no matter how stupid he is, he knows that the value of this pair of plates will not be much higher than the price just now, and this result is simply unacceptable to him. of. You must know this pair of plates, but he spent all his savings a few years ago and borrowed some money to buy it. Moreover, his family did not approve of his purchase at the time. In the end, he bought it secretly. The result now is undoubtedly that He was given a blow. How could he deal with his family, and how could he face those longing eyes at home? Thinking of this, the middle-aged man shouted: "You are all profiteers and liars!" With that, he turned around and ran out. Seeing this, Chu Chen and Feng Zhengjian looked at each other, then shook their heads and sighed. Feng Zhengjian sighed: "Some of today's experts are really unreliable!" Chu Chen also sighed: "There is no way, some people are just interested in money, and these experts who act as "trustees" are becoming more and more popular now. There are more and more of them, and they even ignore the common sense of cultural relic identification, confuse right and wrong, and mislead collectors who believe in them. It¡¯s really disgusting!¡± ¡°Hey!¡± Feng Zhengjian shook his head and said, ¡°Okay. Let¡¯s not talk about this anymore, let¡¯s talk about business.¡± ¡°Okay, I need to ask Boss Feng for advice!¡± Chu Chen said with a smile. Feng Zhengjian quickly waved his hand and said with a smile: "Don't take advice seriously, let's learn from each other." "Then Boss Feng, what should I do now?" "Let's do this!" Feng Zhengjian thought for a while and said, "I'm going to get something, let's go first Let¡¯s take a look at the things.¡± This is the antique business. No matter how good the theory is, it is not as important as practice. If you only follow the standard answers in the book to compare the decoration, vessel shape, hair color, etc., with the current development of science and technology and the continuous improvement of the level of counterfeiting, If it is improved, I am afraid that theoretical experts will also be confused. Therefore, Feng Zhengjian wanted to see Chu Chen¡¯s eyesight first. He had good eyesight. Ask some more theoretical questions. If the theory is also passed, that's fine. After a while, Feng Zhengjian came out with a brocade box, put it on the table, opened it, and said with a smile: "Mr. Chu, could you please take a look at this first?" "Eh!" Box There was a small bowl inside. Chu Chen took a closer look and exclaimed, "Is this a work from Yaozhou kiln?" Feng Zhengjian smiled and said, "Mr. Chu has good eyesight. This is indeed a piece from Yaozhou kiln." A green glaze bowl with engraved floral patterns. Please identify the year it was made" After receiving Feng Zhengjian's instructions, Chu Chen picked up the small bowl in the box and looked at it carefully. Yaozhou kiln is also one of the famous kilns in the Song Dynasty. It began in the Tang Dynasty and reached its peak at the end of the Northern Song Dynasty. Finally the Yuan Dynasty. Its kiln site was located in Yaozhou during the Song Dynasty, hence the name "Yaozhou Kiln". In the Tang Dynasty, Yaozhou Kiln began to produce black glaze, white glaze, green glaze, tea powder glaze and white glaze green, brown, black and three-color pottery. In the Song and Jin Dynasties, celadon was the main type. The bowl in Chu Chen¡¯s hand is a typical Yaozhou kiln celadon bowl, with a straight mouth, curved belly and round feet. The carcass is slightly thick, fine and firm, off-white, the glaze is moist and transparent, the glaze color is green like olives, and the thinner parts are ginger yellow. The glaze color of Yaozhou kiln porcelain is emerald green, the glaze is fine and moist, the glaze is thin, and the glaze color varies in shades. Some are slightly greener, and some are slightly yellower, but they are all green with flashing yellow. No matter how dark the glaze is, it is rich in yellow content. Otherwise, it would not be Yaozhou kiln but a celadon product from other kilns. And this is one of the reasons why when Chu Chen saw the small bowl just now, he felt that it was probably from Yaozhou kiln. Judging from the body glaze, this should be a Yaozhou kiln work from the Song Dynasty. This is because the Yaozhou kiln works from the Tang and Five Dynasties have a slightly loose body and are gray in color. The glaze is devitrified and has a milky feel. In the Jin and Yuan Dynasties, the fetus was slightly thicker, the color of the fetus was light gray or grey, the glaze was mostly turmeric, less cyan, and the enamel was thin and not moist. In addition, the glaze of this bowl has a strong gloss. Although the glaze is thin, it has high hardness. There is basically no glaze flow, glaze accumulation and dry glaze phenomena that existed in the Tang and Five Dynasties. Moreover, the glaze is very tightly combined. Therefore, Chu Chen judged that this bowl The bowl should be from the Yaozhou kiln in the mid-Song Dynasty. The glaze application process of Yaozhou kilns in the Song Dynasty was still deficient, so glaze was often leaked from the back of the utensils near the feet and bottom. These exposed parts of the glaze show some small plaques caused by brown iron oxide. Because the iron content in the soil is relatively high, the thin glaze on the lower part outside the body of the vessel often reveals a faint hint of light brown. These features cannot be imitated by subsequent imitations, and are also an important basis for determining authenticity. And this oneThe bowl has such authentic characteristics. In addition, Chu Chen used a high-power magnifying glass to look at it. There were no small iron particles in the carcass. No makeup soil was applied, but there was an obvious white interface layer. This was in line with the craftsmanship characteristics of the time. After looking at the glaze, Chu Chen carefully looked at the patterns on the bowl. The outer wall of the bowl was decorated with carved patterns. It uses the "half-knife mud" technique of alternately using a straight knife and an oblique knife to express the yin and yang back of the entwined flower pattern. The knife technique is flexible, sharp, smooth, powerful and affirmative, has a strong three-dimensional effect, and has a simple and bold decorative effect. Seeing this, Chu Chen was basically 80% sure that this was an authentic product. However, this bowl should be an unearthed artifact. There was still some rust and dirt on the bowl. Since it was for identification, these should also be Just observe it carefully. He scraped the rust with his fingernails, and it was indeed indelible, as is generally believed to be true. Looking at the rust more carefully, he felt that the rust had some weird feeling to it, which made him frown. You know, after his body has been transformed by supernatural powers, his senses have become more and more acute. A strange feeling suddenly appeared, which made him instantly feel a bad premonition. So he quickly used a magnifying glass to carefully observe the soil, and he clearly saw that there was a large amount of Qin soil in the glaze bubble, and it was very different from the naturally formed Qin soil. Seeing this, he knew that this bowl was probably a fake. The soil rust and soil secretion were fake, but the bowl looked real. This made Chu Chen somewhat strange, so he simply used the Lingbao Eye, but the result of the supernatural power surprised him. So he quickly observed the bowl carefully again, and immediately found a clue according to the place pointed out by the Lingbao Eye. This shocked him and he couldn't help but admire the craftsmanship of the forger. "Mr. Chu, what do you think of my bowl?" Feng Zhengjian asked after seeing Chu Chen put the small bowl back into the box. "I'm not sure about this thing!" Chu Chen shook his head. "What! How can it be inaccurate!" Feng Zhengjian said with a face full of surprise: "My bowl is an authentic Yaozhou kiln from the Song Dynasty! Look at this glaze, this body, how does it look like a fake?" Chu Chen quickly said: "Boss Feng, don't worry! I'll point you to a few places and you'll know if the stuff is right." As he said that, he took the small bowl back into his hand, turned on the strong flashlight, and pointed it at the bowl. A place on the inner wall was illuminated: "Boss Feng, look here!" Boss Feng looked over with the flashlight, and his face immediately turned pale. Under the reflection of the strong flashlight, a faint line could be seen in that place. Traces, and the experienced man, he immediately understood that his bowl should be a new one. Feng Zhengjian was stunned for a long time, then shook his head and said with a bitter smile: "I didn't expect that the one time I was proud of picking up a leak was just another eye shot. If I hadn't taken it out today, I would still have done it. I have always been kept in the dark, Mr. Chu, thank you so much this time!" Speaking of which, Feng Zhengjian also had a sudden idea this time. He was originally planning to test Chu Chen's eyesight with a high imitation, but he suddenly thought of it. , perhaps he could use people's misunderstandings to catch him off guard. In this way, he replaced it with the Yaozhou kiln celadon bowl that he had always thought was genuine, but the result was far beyond his expectation. "No, no!" Chu Chen waved his hand and said, "This bowl actually opened my eyes. To be honest, at first I thought this bowl was a genuine one, but in the end I saw the rust on it. It was only then that I realized that there was something wrong with this bowl. ""Tuzu and Tuqin?" Feng Zhengjian looked at the dirt and soil on the bowl with some confusion and said, "This is rust. Isn't He Tuqin right? What's the problem? " "This is not the real rust and Tuqin, but artificially added." Chu Chen explained: "Most people think that as long as the unearthed porcelain is genuine, then the rust on it is not real. The rust must be very hard and cannot be removed, and the rust will penetrate into the glaze bubbles and even penetrate into the fetal bones. It can be easily observed with a high-power magnifying glass. " "Actually, although this phenomenon also occurs, it is rare. , and many of the so-called unearthed porcelains with these two phenomena on the market are actually fakes. " "What do you mean?" Feng Zhengjian asked. "Let's talk about rust first." Chu Chen said: "Boss Feng, you must also know that some modern super glues have very strong adhesion and are difficult to remove even with hot water boiling and knife scraping. And those Counterfeiters mix loess and color with strong glue and attach it to the surface of the utensils, thereby forming rust. " "And soil Qin is caused by using strong acid and high pressure to penetrate the color. The principle is very similar to the coloring method in jade C goods. Think about it, even jade can penetrate it, let alone porcelain with a much lower hardness than jade. These two kinds of fake "unearthed porcelain"?"The method did not appear not long ago. It existed six or seven years ago at the latest, and there are not many people who have been fooled. Even many experts have looked at it."
