Seeing that Chu Chen was so happy to learn from her now made her feel excited. At the same time, she also made up her mind to learn this aspect well and not let Chu Chen down "Brother, I see you are so careful, this one Could it be that the azure-glazed round washer is from the famous Ruguan Kiln?¡± ¡°Xiaolan, you guessed right, this round washer is from the Ruguan Kiln,¡± ¡°It¡¯s true!¡± Seeing Chu Chen's affirmative answer, Chu Yulan couldn't help but show surprise on her face, and she couldn't help but want to take a look. "Brother, can I take a look?" Chu Yulan asked weakly. "Haha, there's nothing wrong with that." Although the things were indeed relatively precious, Chu Chen was not too cautious. He immediately nodded and agreed to Chu Yulan's request. "Thank you, brother!" Chu Yulan responded sweetly, and then specifically asked Chu Chen for a pair of gloves. After putting them on, she started to pick up Yuan Xi and observe them carefully. After watching for a moment, her face gradually changed, her brows furrowed slightly, with a bit of admiration, surprise and obsession, and finally there was a hint of doubt on her face "Brother, I read what is written in the book, Ru The kiln's utensils are made of incense ash, but why can't I tell?" Chu Chen chuckled and said, "Xiaolan, you are observing very carefully, but you must know that this round wash is "full of glaze" Ru kiln porcelain that is "Azuchi fired" has no exposed parts, and even if it is pad-fired Ru kiln porcelain, although it has exposed parts, if we look at it now, it should look like "copper bones". "Huh? What is "copper bone"?" Chu Yulan asked dumbly. Chu Chen explained to her: "In Zhao Ruzhen's "Antique Guide", there is a description of "copper bones". "The unglazed ones are called copper bones. Because the soil is mixed with metal, it is light red, rather like sheep liver. . ", "There are often unglazed areas, and the color is like the fetal bones of sheep liver, which was the fashion at that time. People who have this kind of phenomenon are considered beautiful, so they attach great importance to it. "" "Then why did it become a "bronze bone"?" Chu Yulan asked curiously. Chu Chen laughed and said: "Actually, this is very simple. We know that the porcelain bodies of Ru kiln in Song Dynasty are all gray-white, with different shades. They are similar to the burned incense ash, so they are commonly called "incense ash bodies". This is indeed correct. However, this definition is only very correct in the short term during the Northern Song Dynasty and beyond. " "After more than nine hundred years of history, dust, soil and other substances in the surrounding environment are prone to chemical reactions with the surface of the tire. The "ash body" has also changed from a superficial phenomenon to an intrinsic substance. Its unglazed surface has become a "copper bone". This phenomenon is a trace left by the years and is also quite difficult to imitate. " "Xiao Lan, You also know that a complete Ruguan kiln porcelain is very rare now, so what we usually call "incense gray body" is just a conclusion drawn from the observation of new cross-sections of Ru kiln porcelain, so in the future you will encounter You must be cautious when buying Ru kiln porcelain. " "For example, next time you encounter a piece of Ru kiln porcelain, no matter how fancy the seller is, as long as you see the "incense gray tire" in the wear and tear on the body, then You should be careful when buying, as this is likely to be a fake." After hearing Chu Chen's words, Chu Yulan couldn't help but look surprised. "Brother, what you said is really good, but what you said is not written in the book I bought. Did I buy the wrong book? Then how should I choose this kind of book?" Chu Chen said with a smile: "Okay, let's not talk about him first. Can you tell me how you bought the book in the first place?" "I just choose the thicker books with more comprehensive introductions. As long as the publisher has no problem, I will buy them." Chu Yulan Said a little embarrassed. "Xiaolan, if you just want to learn more or are a beginner, there is nothing wrong with choosing a book like this. However, if you want to study in depth, such a large and comprehensive book is definitely not enough. Because ceramics in various eras, They all have their own characteristics, and there will be differences even in the early, middle and late periods of a period. "Chu Chen explained: "It's like the enamel colors of the Qianlong period. Because Emperor Qianlong had a special liking for pastels, Works between pastels and enamels appeared in the middle and later periods. Therefore, if we want to study ancient ceramics, it is not enough to just read one book. We must read more books, make more comparisons, and make reference to the descriptions of the same period in various books. "Of course, not everything in the book is correct. Some are due to the limitations of the times, and some are due to the author's incompetence in this book. So what was written was incorrect. ""Like "Jade Chronicles" written by Chen Yuanxin in the late Qing Dynasty, this book is undoubtedly a good book and has a great influence on the ancient jade industry.?The true knowledge and insights contained therein were beyond the reach of previous literati. However, due to the limitations of science in his era, some knowledge is undoubtedly wrong from our modern perspective. " "For a book like this, the writing itself is very good, but it also has errors, so when reading it, we have to use our brains more to avoid being affected by it. Seeing Chu Yulan nod thoughtfully, Chu Chen continued: "Of course, if you want to learn about antiques well, reading books is definitely not enough. We also have to see the real objects." As a new scholar, if there is no master to guide you, it is best not to go to the antique market at the beginning. The first place to go should be the museum. " "In this way, you can use the exhibits in the museum that have the exact year of excavation or have been circulated in an orderly manner as standards for appraisal, and then go to the antique market to compare them one by one. By doing this, I believe your level will be improved quickly. " "Finally, if you see a fake, if you are not in a hurry, don't put it aside in a hurry, but observe carefully. The counterfeiting method of counterfeiting, using false to identify the real, is also the key to antique appraisal. A better method. " Chu Chen's words made Chu Yulan nod her head repeatedly. "Brother, thank you for telling me so much. " "Haha, you're welcome, this is just my little experience. By the way, Xiaolan, you came in just now, are you okay? "Chu Chen asked. Chu Yulan quickly replied: "Oh, brother, I want to ask you what your plans are. " "There's nothing to do today. I want to pay homage to my dad later, and then we can go back to Beijing. " Hearing this, Chu Yulan said a little coyly: "This brother can I go together? " "This" Chu Yulan's request really made Chu Chen a little embarrassed. He really didn't know much about this aspect. Seeing this, Chu Yulan quickly said: "Brother, I know this request is a bit presumptuous. I just want to say thank you to my parents and me, and if it doesn't work out, that's okay. " Chu Chen thought for a while. After all, visiting the graves was just a feeling to commemorate the ancestors, and it also fulfilled a long-cherished wish of his father for many years, so he nodded and agreed
