Chu Chen introduced his guess to several people present. When everyone suddenly realized it, they were also surprised that Chu Chen knew so much about the methods of fraud. If they hadn't known that Chu Chen was a well-known expert and looked like he wasn't short of money based on his clothes, they would all have thought that Chu Chen might be a counterfeiter of high-quality ancient porcelain. If Chu Chen knew what they were thinking, he would definitely smile bitterly. Who told him to have a well-informed teacher? Moreover, the teacher kept asking him to memorize these methods for imitating ancient porcelain. Fortunately, he had a photographic memory, otherwise just these information would make his head grow bigger. At this time, Brother Zhang thought of a question, so he asked: "Teacher Chu, is the black liquid around the crack just now an asphalt solution?" Chu Chen said: "Yes, that jar should be made of asphalt. Too old. "The asphalt solution aging method is a commonly used method for antique porcelain. It first dissolves asphalt in gasoline, and then applies the asphalt solution to the surface of the object. After the gasoline evaporates, the excess is removed with detergent such as detergent. of asphalt removed. In this way, the old appearance of the handed down products can be imitated. However, the "old look" generally produced by using asphalt solution has a single color, lacks layering, and sometimes has traces of brushing. And just use a cotton swab dipped in 120# solvent gasoline to smear the stain. If the stain is immediately dissolved, it means the asphalt solution is old. Chu Chen estimated that there would be asphalt solution around the cracks in the jar, and the counterfeiter might have poured the solution into the bottle to rinse it. Due to a crack in the sole, the asphalt solution seeped out and contaminated part of the sole. Since it is not obvious, the counterfeiter may be too lazy to remove it. This is the time. Brother Zhang and others no longer have any doubts about the authenticity of Xiao Guo's piece of porcelain. Considering that it had delayed Chu Chen for so long, the group expressed their gratitude to Chu Chen for his explanation, and then prepared to leave. But, at this moment. Brother Zhang's cell phone rang suddenly. He picked up the phone, put down the phone without saying a few words, and quickly said to Chu Chen: "Teacher Chu, Xiao Guo's master wants to invite you to his shop. Do you have time? If you don¡¯t have time, he said he would take Xiao Guo to your store to apologize. " Anyway, he has nothing to do, so it¡¯s okay to go there, but Chu Chen needs to know who the other party is beforehand. That's fine, after all, the whole antique street. Not everyone has a very good relationship with him. So, Chu Chen asked: "I wonder who Xiao Guo's master is?" Brother Zhang replied: "Xiao Guo's master is the shopkeeper Peng of Yaxiangzhai." Yaxiangzhai mainly deals in spices and aromatherapy stoves. This kind of antique shop has been open for a long time. Chu Chen is also familiar with the shopkeeper Peng. In addition, they are all members of the Beijing Antiques Association. No matter what, Chu Chen has to give him face. OK. "Okay. I'll be there right away" Seeing Chu Chen agree, Brother Zhang said a few more words to the phone, and then prepared to leave. After all, shopkeeper Peng's intention was very clear. He just wanted Xiao Guo to apologize to Chu Chen. If they went together, they would be suspected of seeing a joke. However, before leaving, Brother Zhang asked with a smile: "Teacher Chu, do you also open a shop here?" Chu Chen pointed to his shop with a smile and said: "I opened this Ciyi Zhai. " "Ah! It turns out you opened this store!" Brother Zhang and the others were a little surprised, you know. This porcelain restaurant is very popular in the antique street now. In addition to the fact that except for some high-imitation porcelain with clearly marked prices, everything else is genuine. The endless supply of high-end jade jewelry has also made this place frequented by many dignitaries. ¡° Moreover, Brother Zhang and the others also heard that the owner of Ciyi Zhai has a very strong background. No matter how good the business is, no one dares to come here to cause trouble. This has also become a hot topic in the antique market. Although Brother Zhang and the others had heard that the owner of Ciyi Zhai was named Chu, they did not expect it to be Chu Chen. After all, Chu Chen is too young, and Chu Chen seems to be very humble, not at all like a boss with a powerful background. Therefore, they were so surprised when they learned that Chu Chen was the owner of this antique shop. "Can I still lie to you about this?" Chu Chen chuckled. "Where! Where" Everyone said they were just too surprised. Then Brother Zhang said: "Teacher Chu, we won't waste your time" After saying goodbye to Brother Zhang and others who were very polite, Chu Chen went straight to the Yaxiang Zhai mentioned just now. As soon as he walked to the door, He smelled a faint fragrance. Judging from the smell, it should be a combination of spices. When Chu Chen walked into the store, he found a man in his fifties.The old man was lecturing Xiao Guo with a somewhat stern expression, while Xiao Guo stood aside without saying a word with his head lowered. Seeing this situation, Chu Chen secretly smiled. Although the old man's expression did mean that he hated iron for not becoming steel, he could still tell that the scene in front of him should have been deliberately done by the old man. As for the purpose, it was not. It goes without saying. As soon as the old man saw Chu Chen coming in, he quickly yelled at Xiao Guo: "You haven't apologized to Shopkeeper Chu yet!" "Shopkeeper Chu, I'm sorry, it was my fault just now, I shouldn't be so rude, and I shouldn't be so unreasonable ¡¡± Xiao Guo lowered his eyebrows and apologized to Chu Chen in a sincere tone. However, Chu Chen felt that Xiao Guo seemed to be a child who had done something wrong and was reviewing it to the teacher. This feeling made him He found it very funny. Chu Chen smiled and waved his hand: "It doesn't matter. I had my eyes pierced before, and there were quite a few. I can understand your mood." Seeing that Chu Chen's attitude really didn't care about this matter, Shopkeeper Peng felt relieved. He breathed a sigh of relief. As a member of the Beijing Antiques Association, he knew how profound Chu Chen's background was. If his apprentice really made Chu Chen angry, there would probably be no good fruits in the future. "My apprentice is very smart, but his mental endurance is really poor. He still needs to train more in the future!" Seeing Xiao Guo standing stupidly without saying anything, Shopkeeper Peng sighed inwardly. , and shouted loudly: "Thank you, Shopkeeper Chu!" "Thank you, Shopkeeper Chu!" "Go and get the brocade box on the table in the back room." Shopkeeper Peng waved to Xiao Guo, and then asked Chu Chen to sit down. After pouring him a cup of tea, he smiled bitterly and said: "This apprentice of mine is sometimes too clever and doesn't know when he will be able to leave!" Chu Chen said with a smile: "Shopkeeper Peng, you don't have to worry too much, just like just now When I entered this profession, my personality was even more introverted than your apprentice. After several years of training, I am at least qualified!" Shopkeeper Peng shook his head: "How can he compare with you, Shopkeeper Chu? I only want him. If I can have half as much as you, I can burn high incense" The two chatted for a while, then saw Xiao Guo walking out of the back room holding a brocade box and putting the box on the table. Shopkeeper Peng opened the lid of the box and pushed the box in front of Chu Chen: "Shopkeeper Chu, see if you like this thing!" Chu Chen took a look and saw a peacock blue glaze plate inside, with a smooth and thin glaze. The glaze color is bright and bright, which is pleasing to the eye, but you can tell that this thing is worth a lot of money at a glance, and from what Shopkeeper Peng wants, it seems that it is transferred to him. So, Chu Chen raised his head, frowned slightly and asked: "Shopkeeper Peng, what do you mean?" Shopkeeper Peng chuckled and said: "Shopkeeper Chu, take a look first, don't worry! I'm not giving it to you, and To be honest, I can¡¯t bear to give this to you!¡± ¡°Okay, let me take a look first!¡± Chu Chen nodded and took out the plate. Peacock blue glaze, also known as "French blue", is a low-temperature glaze that uses copper as a colorant and displays a bright blue tone after firing. Generally, blue glaze is fired at high temperature, and the glaze surface is not easy to fall off. Peacock blue glaze is a low-temperature glaze. The green body is glazed, or the white glaze is glazed twice and fired. Because the color of some utensils is green, some people also named them "malachite green" or "facui". Peacock blue glaze is a traditional glaze in West Asia. It has a long history and was introduced to China very early. Three peacock blue glazed pottery bottles were unearthed from the tomb of Liu Hua, Queen of Fujian during the Five Dynasties and Ten Kingdoms period. The official kilns of the Ming and Qing Dynasties all fired peacock blue glaze wares, and the color tone and glaze quality of each dynasty were different. The peacock blue glaze plate in Chu Chen's hand is a treasure. It has an open mouth, a solitary belly, a circle foot, and green glaze inside. The center of the plate is secretly engraved with dragon and phoenix patterns. The carvings are powerful and vivid, and the inner edges are dark. Carved with a wavy pattern, the lines are smooth, beautiful and natural. There are two dark engraved string patterns on the outer edge and near the foot. The theme decoration is painted with nine clouds and dragons in different shapes, rolling on the sea water of the river cliff. The peacock blue glaze is applied on the outside, and the glaze surface is shiny. The bottom is exposed, and the outer edge is secretly engraved with the six-character regular script "Xuande Year of the Ming Dynasty". Peacock blue glaze blue and white products have been produced in the Jin and Yuan Dynasties, but the color of the cobalt material is obviously darker. This is not only related to the immature firing technology and the direct application of peacock blue glaze to the carcass and firing in the kiln, but also may be related to the production of plain tires. When the cobalt material is burned naked, it is related to the oxidation and blackening of the blue and white. ¡°As for the peacock blue glaze plate in Chu Chen¡¯s hand, the cobalt material has a correct color, and there are no traces of blackening due to bare firing. If you carefully observe the edge of the plate, you can also find that the interface between the secondary peacock blue low-temperature glaze and the primary high-temperature glaze is exposed. Chu Chen speculated from this that this may be a secondary process in which the imperial factory at that time first fired the high-temperature plain body with glaze on the inside and no glaze on the outside, and then painted the outside with cobalt material and applied peacock blue glaze for firing.This ensures the ideal hair color of underglaze blue and white. But in any case, the performance of this peacock blue glaze should undoubtedly be the characteristic of the authentic Xuande official kiln in the Ming Dynasty. In addition, from the characteristics of the plate's texture and other characteristics, Chu Chen can confirm that it is indeed an authentic product. Because the peacock blue glaze is a low-temperature glaze, the glaze is thin and it is very difficult to fire. Therefore, the peacock blue glaze is rare and rare. Moreover, because the glaze is thin, it is easy to peel off over time, so it is easier to preserve. difficulty. The peacock blue glaze plate in front of you from the Xuande period of the Ming Dynasty has been in good condition for hundreds of years. It can be said that it is something that can only be found but not sought. It is very rare. (To be continued)
