Ye Zhiqiu took a sip of wine and said lightly.
"In the Yuan Dynasty, blue and white porcelain used the techniques of dipping, pouring or brushing glaze. Therefore, the glaze was very thick, but overall it was not smooth and flat."
"Large objects like plum vases are usually glazed, and there will be 'tear marks' on the surface. If you have seen construction workers painting the wall, there will occasionally be little dripping spots of paint on the wall. Yuan blue and white porcelain There will also be a little bit of enamel buildup on the surface.”
"But if you reach out and touch it, the glaze of your blue and white porcelain is too smooth and smooth!"
Du Mengying curiously reached out and touched the surface of the blue and white porcelain, frowning and said: "Zhiqiu, sure enough, there is no trace of that kind of dripping."
Her beautiful eyes were fixed on Ye Zhiqiu, with a hint of smile flashing in her eyes: "Zhiqiu, you are so awesome, you can tell by just touching it with your hands!"
"It's actually very simple. If you know more about antiques, it will be easy to identify them!"
Ye Zhiqiu shook his head and said with a smile: "After the Qing Dynasty, Jingdezhen generally used the glaze blowing method to apply glaze, and the technology was greatly improved than before."
"Now, air compressors are used instead of manual glaze blowing, and there are no such defects as Yuan blue and white porcelain."
"If people today don't understand, even if they find these 'tear marks', they will think that they were accidentally dropped by the craftsmen during production. When making fakes, they will actively avoid leaving drop marks and strive to be more perfect."
"As everyone knows, the occasional drop marks prove that they are caused by the craftsmanship of the Yuan Dynasty and are actually genuine!"
Du Mengying smiled sweetly.
"This is really a clever mistake that was mistaken for you!"
Her smile bloomed like a spring flower, and Ye Zhiqiu couldn't help but be stunned.
Guan Haowen's face was ashen: "You can conclude from this that it is fake?"
Ye Zhiqiu glanced at him disdainfully and snorted from his nose.
"If I rely on this alone, isn't that too arbitrary?"
"Sister Mengying, look at the inner wall of the vase. What's there?"
Du Mengying aimed one eye at the diameter of the vase and looked inside.
She suddenly said in surprise: "Zhiqiu, the inner wall is not glazed. There are some fingerprints on it and some jagged marks, as if it had been scraped with a hacksaw."
"Fake! This faker was so careless! He even forgot to apply the glaze on the inside!"
Ye Zhiqiu held back his laughter and glanced at Guan Haowen again.
"Master Guan, take a look, is there anything inside?"
Guan Haowen took the vase doubtfully, looked inside for half a minute, and said doubtfully.
"Except for the flaws discovered by Miss Du, there is nothing else!"
Ye Zhiqiu looked at Du Mengying with a smile.
"Sister Mengying, only if the inner wall of Yuan blue and white porcelain is not glazed, can it be real! The ancients never glazed the inner wall! If the inner wall is glazed, it is definitely a fake!"
Du Mengying's face suddenly turned red with embarrassment. She didn't expect that she had just made a big fool of herself.
"Zhiqiu, are you kidding me? Are you looking at me for shame?"
Guan Haowen also stared at Ye Zhiqiu with a puzzled look.
They are all laymen and do not understand some of the secrets of antiques at all.
"Not really!" Ye Zhiqiu smiled slightly.
"Sister Mengying, you just said that there are dense jagged knife marks on the inner wall, which is evidence of fraud."
Du Mengying looked at him with a strange expression: "Huh? What do you mean?"
"Jingdezhen ceramic craftsmen use two types of knives to repair the blanks. One is the board knife. The board knife has been invented for more than 2,000 years and is used to trim the outer walls and foot rings."
"The other type is the strip knife, which is used to trim the inner wall of porcelain. This kind of knife was only invented during the Kangxi period of the Qing Dynasty!"
Du Mengying's eyes lit up: "In other words, before Emperor Kangxi of the Qing Dynasty, the inner walls of ceramics were not trimmed, so this blue and white porcelain is fake at first glance!"
"That's right." Ye Zhiqiu nodded and smiled.
"Moreover, he trimmed the inside, leaving even and detailed sawtooth knife marks!"
"Before the Ming Dynasty, craftsmen's trimming knives were handmade by blacksmiths and then carefully ground with whetstones. After the European Industrial Revolution, their steel files were introduced to our country."
“The craftsmen found that steel files were easier to use than the original trimming knives. As a result, when they trimmed the ceramics, they naturally left jagged marks!”
"Yuan blue and white porcelain doesn't need a steel file to trim the blank. You can tell at a glance that it's fake!"
Guan Haowen was also as black as the bottom of a pot, staring at him coldly.
"On the basis of these two points, you dare to conclude that this blue and white porcelain is fake? My second uncle is the vice president of our Jianghai City Appraisal Association, and he didn't even notice it!"
Ye Zhiqiu was slightly startled. He didn't expect that his second uncle had such a powerful background.
"There's a lot of evidence! At least a dozen of them. Do you need me to point them out to you one by one?"
"Yuan blue and white porcelain has large flowers and leaves, and the leaves are full of color, but the flowers and figures and costumes are not full of color. Your flowers, figures, and stones are all blue. It is fake at first glance!"
"As for why your second uncle didn't notice it? What's so strange about when people make mistakes and horses stumble? You can go back and ask your second uncle if these are flaws!"
Guan Haowen clenched his fists tightly with both hands, and veins popped out on his forehead.
In the evening, his second uncle hurriedly collected the blue and white porcelain, and was invited by some old friends to drink. Before he could appreciate it carefully, he stole it.
Du Mengying stared at Ye Zhiqiu intently, and said with a smile: "Zhiqiu, are you saying that this blue and white porcelain is a modern imitation, right? Isn't it worthless at all? Junk goods, right?"
Ye Zhiqiu shook his head, "It's not a fake made now, it's a fake Yuan blue and white porcelain made in the last years of Kangxi. After all, it can be regarded as an old item with a history of hundreds of years!"
"It's also somewhat valuable, but it won't exceed five million at most!"
"If it's worth 1.5 billion as Young Master Guan said, his second uncle would be too impressed!"
"Only worth five million?" Du Mengying smiled helplessly. The price was so different that it was not even a fraction of the original price.
Seeing Ye Zhiqiu's words, Guan Haowen knew that he was not telling lies. His face turned red and white, and he walked out angrily.
The driver, Lao Liu, was waiting outside the door. Seeing this, he rushed in quickly, picked up the plum vase and chased after her.
"Master, vase! Master, vase!"
Guan Haowen was full of anger and had nowhere to vent. When he heard this, he grabbed the plum vase and hit him hard on the head. With a "bang", the plum vase shattered on the ground.
The driver screamed "Ah", blood dripping from his head.
Du Mengying and Ye Zhiqiu glanced at it from a distance, and suddenly couldn't help but laugh.
Only such incompetent trash would take it out on his subordinates.
"Zhiqiu, you still said you don't know how to identify treasures? Are you going to do it to yourself now?" Du Mengying smiled.
Ye Zhiqiu hurriedly said modestly: "Lucky! Lucky!"
"I happened to be reading books about Yuan blue and white porcelain today, so I was just trying to catch up!"
