Chapter 514 Flaw
Zhou Zhi couldn't help but feel a little embarrassed: "Mr. Zhang, why don't you arrange for my elder friends first?"
"No, I'm with you." Jiang Shuyi said.
"Well, I'm also with Brother Jiuzi." Guan Tingting also said.
Mr. Qiao made a fool of himself again, staring at the pin that day: "Elbow, how did you see the Republic of China? I think it was Tongzhi..."
This is unreasonable nonsense. Zhou Zhi couldn't laugh or cry: "You are even more outrageous than someone who died in Qianlong..."
Guan's mother smiled and said: "Actually, those who can collect antiques are all refined people. Experts are all people who are not short of money, so what they value is not The value of the collection in your hand depends on the culture and knowledge contained in it. "
People nowadays still like to save face. Guan Ma has a good temperament, and the middle-aged woman has a more graceful temperament. Such a confrontation made several men speechless.
"I have heard some ancient sayings that say, 'There is no priority in learning, and the master is the teacher.' I have also heard that 'He who hears the Tao in the morning will die in the evening.'" Guan Ma's eyes were full of smiles: "So Please don’t regard today’s matter as a dispute of temper. Whether you win or lose, just treat it as a cultural discussion."
"Yes, this lady is right." Mr. Zhang quickly smoothed things over: "It's like talking to each other, that's what I mean. ”
"Respect should be given to people with skills, not to someone who can fool himself into an expert by saying a few words." Although Guan Ma was able to save his face, the middle-aged man still refused to accept it.
"Tell me the reason for your estrangement." Mr. Zhang said.
"Then... let me tell you?" Zhou Zhi looked at the middle-aged man and said with a smile.
"Say!"
Zhou Zhi stretched out his hand to hold the mouth of the bottle and tipped it down: "Let's talk about the foot ring and the bottom payment first..."
"Children, is it professional to touch antiques without wearing gloves?" the middle-aged man sneered.
"Huh?" Zhou Zhi was stunned instead: "Of course other antiques can't be used, but the porcelain industry has never been so particular."
"Because the glaze applied on the surface of porcelain is essentially The silicide glass itself is resistant to acid, alkali and corrosion."
After speaking, he looked at XCMG with a half-smile: "If you put it on. If you use gloves, the surface friction will be reduced and it will be too smooth, which will lead to mistakes. Therefore, it is always possible to use gloves to play with porcelain, but it is unprofessional. ”
XCMG quickly raised his hand: "I didn't wear them either, and we didn't give out gloves to customers. They brought their own."
"Is this really true?" The middle-aged man was a little confused: "Mr. Zhang?"
"Young friend Zhou is right." Mr. Zhang said, "You really don't need gloves when appreciating porcelain."
After saying this, the other men beside him also secretly took off their gloves.
Zhou Zhi said: "Let's first talk about why it is not Tongzhi blue and white. My sworn brother was talking nonsense before."
"The blue and white of the late Qing Dynasty, whether it was Tongzhi or Xianfeng, even inherited the predecessors Daoguang, in fact, all have the same problem, that is, the roughness of the glaze is more obvious, and the texture of the folk kiln is softer. ”
"There are also a few that are lighter and thinner, with finer porcelain, but the glaze is uneven and mostly translucent white; while those with thick glaze are more coarse and soft, with turbid glaze, and their transparency and hardness are not as good as those of the three generations of the early Qing Dynasty. "Of course this also means compared with the previous dynasty, even if It is a Tongzhi official kiln, and the imitation craftsmanship cannot be compared.”
“I happen to have a large-open Qianlong official kiln ink clay box here. You can compare it with the bottom. Features.”
After saying that, he took out the Qianlong ink pad box that previously contained the Eight Treasures ink pad and put it on the table: "The base of this ink pad box is a six-character seal script made in the Qianlong year of the Qing Dynasty. The year is broken in strokes. It is the style of the inner government, blue and white. It is made of high-quality Zhejiang material, with purple hair color and bluish bottom. It is delicate and delicate. Please pay attention. Look closely, there is still a little bit of fetal red. "
" Fetal red is also called flint red. It is mostly precipitated from the junction of fetal glaze. The real flint red has a soft and bright color, harmonious and natural, the farther away from the flint is, the glaze. The lighter the red color;"
"The fake flint red can be seen everywhere on the bottom of the utensils. The color is of different shades, either too thick or too light, which is very unnatural."
"If you observe it under a magnifying glass, the real flint red is sparkling and translucent. , penetrate deep into the fetus and blend with the fetal soil The fake flint red lacks vitality and floats on the surface of the carcass."
"According to Mr. Geng Baochang's "Ming and Qing Porcelain Appraisal": "The flint red marks on the carcass feet have appeared since the Yuan and Ming Dynasties." , the earlier the era, the more intense it will be. It gradually disappeared in the early Qianlong period of the Qing Dynasty. '"
"The reason is that people have solved the reason why flint red is produced, that is, the body contains minerals, and the parts that are not glazed will naturally glow when exposed to fire. out, during the cooling process II Formed by secondary oxidation. "
" Even if the blue and white wares of the Yuan and Ming Dynasty copied in Jingdezhen are fired with new sand pads, or the sand bottom of the new porcelain body is deliberately dampened before entering the kiln, it will show flint red. Phenomenon.”
"Although this ink pad box is small, its many features, including the base, glaze color, blue and white hair color, shape, pattern, base, paste, and red body, are all very consistent with the early Qianlong standards."
"In jargon, it's called 'big door', and in modern terms, it's called 'standard instrument.' We can regard it as an important part of the Qianlong official kiln utensils. For reference, compare it with other suspected Qianlong blue and white porcelains as a basis and reference standard for identification."
The middle-aged man held the ink pad box in his hand and studied it for a while, but he could not find any faults. , and then passed it on to everyone for viewing. These people were still able to identify things with wide open doors, and they all nodded in agreement with Zhou Zhi's statement.
After receiving everyone's approval, Zhou Zhi turned the ink pad box over to reveal the bottom of the tire, and then revealed the bottom of the celestial sphere bottle: "Look again, can you see the difference now?"
It is indeed easy to identify. One person pointed to the Tianqiu bottle: "The bottle body is more white and thin."
"That's not right." The middle-aged man was confused: "Didn't it mean that after Kangxi and Qianlong, the blue and white carcass became thicker towards the back? Why did it become thinner instead?"
Zhou Zhi smiled and said: "The so-called rough here refers to the craftsmanship, such as tire scraping, tire splicing, tire repair, and of course the fine mud washing. The degree is also included, but that is based on Yongxuan blue and white as the top standard, and cannot be compared with the chemical tires of the mechanical age."
"The flaw of this celestial sphere bottle is here, this tire of soil. Therefore, it will become too greasy and white. That is because there is an additional process that will only be available in later generations - —Removal of iron. ”
“Removal of iron is a standard process for making porcelain clay in later generations. Because steel ball milling is mostly used as a process for making clay powder, in order to maintain the quality of porcelain clay, more water is needed before making clay. A process of removing iron, so that the fired porcelain body will be white and flawless. "
“The previous tire soil did not have this process, so no matter how delicate it is, there will still be brown and black dots the size of hair tips in the tire soil. This is not caused by the thickness itself, but by iron impurities. It is caused by precipitation, so it is inevitable.”
"This also leads to the fact that the color of the genuine product is more natural than that of the imitation, with a light green or light red color instead of greasy and white."
"The soil of this celestial sphere bottle is wrong. The first flaw is that the red color is too uniform and is deliberately made. This is the second flaw. ”
