Riding the wind of rebirth

Chapter 557 Applause
"After talking about the tire, let's talk about the glaze."

"Ancient porcelain glazes have a remarkable feature, the thicker the glaze, the more obvious it is, that is, the formation and overflow of air bubbles in the glaze during the firing process will form a small and tight 'brown eye' on the surface of the porcelain. Commonly known as 'orange peel pattern', they and the tiny air bubbles in the glaze scatter the light, resulting in a special soft feeling. On the sweet white glaze, it shows a jade-like 'moistness', a sense of oil. "

"Obviously, this piece of porcelain does not have such a feeling. The glaze surface presents a pure glass texture, with light floating on the surface. It is caused by the surface of the new porcelain being too smooth."

"The most important point is that Chenghua Tianbai's white color is actually a complex optical reaction. It is not a pure white, but a warmer-colored porcelain body combined with a cooler-colored glaze color. The pleasing white color displayed, the ancients used the word 'sweet white' to describe it, which is really appropriate."

"Yongle and Chenghua Tianbai, when viewed against the light, the fetal soil presents a kind of flesh red or pink; while on the feet and corners of the utensils, there is often a faint shrimp blue luster. If the glaze is thicker, like a circle at the bottom of a bowl, it will form a magical "lake green" glaze color accumulation, which is very beautiful."

"The recipe of this 'composite sweet white' has been lost since its inception, and later imitations in the late Ming Dynasty were thickened and the firing technology was not good enough, so the glaze surface was flashing yellow or gray;"

"Hongzhi and Jiajing Tianbai glazed wares all have a blue bottom, and occasional sauce yellow spots on the glazed surface;"

"In the Qing Dynasty, the Kang and Yongle sweet white glazes were white and slightly green, relatively shiny, thicker, and decorated with dark carvings. Themes included flowers, landscapes, etc.; In addition to the light, even the bottom of the vessel is transparent, which is the biggest difference between Yongle and Yongzheng sweet white glaze."

"Qianlong's sweet white powder is heavier and whiter, but the enamel is not as fine as Kang and Yong, and the dark engravings are more complicated. The glaze is white, but not moist, and generally flashes blue. , Hongzhi inscriptions, there are blue and white writing, and there are also dark engraved regular script inscriptions, most of which are blue and white;”

"Before I said that your bowl is the sweet white glaze imitated by the Qianlong porcelain factory after the founding of the People's Republic of China. The basis is here."

"Since there are so many characteristics of Qianlong sweet white glaze, why don't you directly say that it is from Qianlong, but say it is imitated from Qianlong?"

"Because the imitations of the Qing Dynasty also have their own characteristics, that is, Yangon perspective, and the fetal glaze is blue-gray;"

"The biggest feature of modern imitations is that in order to achieve the effect, the glaze is much thinner than that of the previous ones, the engraved lines are rough, the patterns are too simple, and the dark flowers and dark patterns are too clear."

"Although some are imitated into thin tires, they are mostly uneven. Moreover, it can be seen through light that the tire quality and hanging glaze are not uniform."

"This is what I said before, where the real craftsmanship is. In these parts, it is difficult for modern factory imitations to compete with the craftsmen of the previous dynasty."

"That's why I dismiss this porcelain as a modern imitation."

"But this consciousness..."

"Yes, this knowledge." Zhou Zhi smiled and said, "It's actually a big loophole."

"what?!"

"Everyone is very familiar with the style of the blue and white double circle containing the six-character year name inscription. For example, most of the official kiln porcelains of the Qing Dynasty and the Three Dynasties are like this. This method is similar to the Ming Dynasty. It does not look bad. This model has become the biggest loophole of this imitation.”

"Ah? Why is this?"

"Because these six characters are orthographic, just like the Song style we see in newspapers today, such inscriptions did not exist in the Ming Dynasty."

"The base of the real 'Daming Chenghua Annual System' is regular script. The sun and moon of the Ming characters are both narrowed at the waist. Rules, showing the overall neatness in the untidyness of the posture changes, and many official kiln porcelains, the base payment is like the hand of one person, which is an important feature of Chenghua porcelain.”

"Although the imitation of this bowl is passable, in this regard, it is still distorted by the Qianlong imitation. The design is neither fish nor fowl."

"To sum up, my appraisal opinion is still the same as before. This is a modern anti-Qianlong dynasty sweet white glaze eggshell bowl. The craftsmanship is exquisite, but it is still a factory product. Compared with the handmade porcelain of modern master craftsmen There is still a gap, let alone the previous generation?"

After Zhou Zhi finished speaking, he didn't bother to talk to the surprised old man in front of him, so he turned to Elder Sun beside him and said, "Old Sun, that's all I can see. I don't know if you have anything to add?"

Sun Lao laughed and said: "There are many imitations of sweet white glazed porcelain on the market, but there is a big gap between them and the sweet white glazed porcelain of the Chenghua period."

"Although the glaze of imitation products in Qing Dynasty is white and fine, although it is also artificially drawn, the carcass is thicker, and the upper and lower sides are relatively uniform, the glaze surface is flat, the workmanship is regular, the glaze color is fine and white, and there is precious light from time to time, but there is no glaze on the accumulated glaze. The lake green phenomenon."

"Modern imitations, mechanical pottery tires, grouting molding, tire repairs and glazes lack exquisiteness. The glaze color is mostly prepared with chemical materials, and the hair color is extremely unnatural. You can't see the precious light, but the 'thief light' is obviously easy to see."

"If you use light to identify, the light transmittance of real sweet white glazed porcelain gradually decreases from top to bottom. This is because sweet white glazed porcelain, from the bottom, waist to mouth, the body gradually becomes thinner from thicker."

"As for the imitations of the Qing Dynasty, the carcass of the whole body is uniform in thickness, so the lightness under the light is basically the same."

"Modern imitators are coarsely refined and have many impurities. Under the light, uneven carcass is more common."

"Another point is that to see the bubbles under the orange peel, you need a twenty-fold magnifying glass."

"Under the lens, the real sweet white glazed porcelain, densely covered with large, medium and small bubbles;"

"Clean imitation utensils, the size of the bubbles is sparsely distributed;"

"Modern imitations are all about the same size and densely packed."

"This sweet white glazed bowl is just like the little master next to me said, many features are the performance of modern imitations, so he didn't miss it."

"At the same time, this is also a rare, vivid and comprehensive lesson on authenticity identification of sweet white glaze. It is so hard to explain, doesn't it deserve everyone's applause?"

"Little master, you have taught me well!" Immediately, some people who were refreshed by this free class and felt that it benefited a lot applauded closely following what Mr. Sun said.

"It's really well said!" With the first one, there will be the second one, followed by applause and applause.

Zhou Zhi had no choice but to stand up and bow to everyone: "Limited level, learn from each other and help each other, thank you for your encouragement."

"It is of course necessary to learn from each other, but please don't judge people by their appearance." Sun Lao said: "You must believe that the teachers we invite in Gongmei are definitely the best in the industry. Not just anyone can come here for appraisal. Master, he can definitely represent the overall image and level of our Gongmei mall, please rest assured about this!"

The applause from the surrounding crowd became even louder.
