"This one is a later imitation!"

Li Ding'an flipped his hand and buckled the flower pot upside down on the long case, "If nothing else, this thing is also combined with the glazing process of the kiln...... Well, it feels like it's something that came out of the kiln......"

Hearing "imitation", Yu Zhengze was still scoffing, and when he heard "building a kiln", he was stunned.

The Jun kiln is glazed with copper, and the kiln is glazed with iron or aluminum...... The former is a dark glaze dominated by purple, and the latter is a black glaze and a green glaze...... How did he get it together?

Yu Zhengze deliberately lowered his head and took a look: That's right, the purple is red, and the red is faintly blue, the typical color of malachite......

Surprised, Li Ding'an picked up the second piece again, and also looked at it very carefully and slowly: "It is indeed a blue and white glaze, and it is also exquisite, but it looks ......."

After a pause, Li Ding'an smacked his tongue, turned over the gall bottle again, and looked at the base: "It's also imitation, and it's indeed imitation of the new official kiln of the Southern Song Dynasty...... And it's from the same kiln as the flower pot! ”

Yu Zhengze was stunned again: "It's better to build a kiln"

"Yes!"

No...... Are you color blind?

Subconsciously, Yu Zhengze raised the blue and white plate in front of his eyes, eager to set his eyes on the bottom foot.

There is a gap on it, about the size of a grain of rice, and it is very new, and it is clear that it was left after the police took samples and tested them.

So you can see the fetal quality from here: a little black, but still almost pure white.

He picked up the gall bottle again, and there was a notch in it...... That's right, they are all close to pure white fetal material, which is not the color that Nanping's soil can burn at all.

After studying ancient porcelain for more than ten years, can you still be wrong about this?

He wanted to laugh unintentionally, but it happened that Zhang Hanguang glanced at him, and Yu Zhengze could only hold back, the expression on his face was extremely strange, as if he couldn't squat out of the toilet:

"Haha...... According to your meaning, the remaining two pieces don't need to be seen, they must be imitations, and there is a chance that they will be built by themselves. ”

"President Yu, don't worry!"

Li Dingan smiled: "I know you want to see the joke, but can you wait for me to finish it first?" ”

Yu Zhengzhi was happy: "Don't ...... I really don't want to see your jokes, I just feel like you're thinking...... Well, it's a novelty! ”

When Li Ding'an first said that the kiln was an imitation of the Jun kiln, Yu Zhengze was indeed a little uncomfortable, and felt that this young man was somewhat "playing with a big knife in front of Guan Gongmen".

No matter how unbearable he is, he is also an authoritative scholar who has won several ministerial awards in a row, and no matter how lame his eyes are, he will not be unable to recognize real porcelain and melamine.

At that time, he almost couldn't hold back, and wanted to ask for a few words.

Later, Li Dingan said "build a kiln", and Yu Zhengze understood: this is a second knife, and he doesn't know how to install hard.

It's not that he's conceited, but common sense: the iron content of Jianyang's soil is too high, so the black porcelain of the kiln is world-famous. If you fire porcelain of other colors, the porcelain will turn yellow, red or even black, so the quality is very average.

And the fetal quality of these two pieces is pure white?

So I can't figure it out, how did Li Dingan get involved?

Unconsciously, Yu Zhengzheng's mentality changed, and the hand holding his arm was put down, and Shi Shiran carried it behind him.

There is no change in his expression, but it can be seen without any psychology: Li Dingan is not wrong, he is just waiting to see the joke.

Zhang Hanguang couldn't stop sighing, but Dai Younian's eyes lit up, and he kept moving around on the faces of the two people.

Li Ding'an forgot about it and looked at the remaining two carefully. In the same way, after reading it, he will turn things upside down, turn them upside down, and turn them face up.

It took him ten minutes before he put down the last blue and white plate. But his eyes were dilated, his expression was glazed, and he felt like he was ...... Idle.

That's right, it's in a daze......

After waiting again, seeing that he didn't mean to come back to his senses, Yu Zhengze clicked the table again: "Still have questions?" ”

Li Ding'an woke up like a dream: "There is indeed a problem: this bag of pulp ...... Very wrong! ”

What does it mean that it is not right, and what does it mean that it is very wrong?

He was just about to ask, but Li Dingan pointed to the blue and white plate again, "This is a traditional old-fashioned technique, so President Yu can see it at a glance." But the last three are all high-tech techniques......"

Yu Zheng was stunned for a moment, and then reacted again: "It means...... I didn't see any of the last three? ”

Li Dingan nodded: "If you want to say that, it's right!" ”

It's really not wrong: the dragon pattern vat is the first piece, but it was smashed by himself, and the purple flower pot is the second piece, and Yu must not have seen it before.

And the remaining two pieces have played new tricks, and the old-fashioned technology is more high-end and realistic than the dragon pattern vat. If it weren't for the extra heart and eye to test it with the system, Li Dingan would have almost thought that these two things were true.

Does it mean that the counterfeiting and antique technology of this group of people is still evolving, and it is progressing extremely fast?

Awesome......

Correspondingly, it's not surprising that President Yu can't recognize it...... It's not just him: just at the same speed as his dog in the back just now, it is estimated that Lu Benzhi and Chen Shouyi will be choked when they come.

"This, hehe...... Okay, even if I don't recognize ......."

Yu Zhengze laughed angrily, "Then according to what you said, these different four kinds of glaze, four shapes, and four kinds of porcelain with four crafts are the same batch of Song porcelain imitated by the kiln built in the Yuan Dynasty?" For some unknown reason, he sank into the sea and was fished up again. But the release is too new, so the toning is redone, right? ”

"It's a bit of a twist, but it's true!"

"You're really good at!"

"It's not me...... President Yu, you are an authoritative scholar in ancient porcelain, and you must know better than me that building a kiln is not only about burning black porcelain......"

Yu Zhengze sneered: "Of course I know, but no matter what kind of porcelain is burned, the porcelain quality of the kiln cannot be so white." ”

"Good...... When the kiln was built to burn celadon, how did the red porcelain fetus fade? ”

"Of course, it is to separate the iron element with magnet after crushing and screening, and then add quartz sand to rot...... But no matter how light it is, it can only be beige! ”

"Right...... What about the Ding kiln, the iron content of porcelain clay was also very high at first, so it was a sauce glaze, and then it was possible to burn white porcelain? ”

"Dig deep earth wells, the deeper the well, the less iron, after the well is crushed, the soil is washed with water, and then separated with magnets, and then neutralized with lime, and the cosmetic soil is used when glazing...... But the whiteness is only about 60%. ”

"What about Dehua porcelain?"

"Dehua is a high-purity white age soil, and alkali such as plant ash is used!"

"What about the green and white glaze of the Yuan Dynasty, why is the porcelain whiter?"

"Of course, it is a secondary formula, adding high-purity aged soil and lime staleness, and the more you add, the whiter it will be."

"That's right!"

Li Ding'an pointed to the gap on the foot of the flower pot, "The more you add, the whiter it will ......be."

For a moment, Yu Zhengze's eyes widened: "Where did Nanping come from such a high level of purity?" ”

"It is true that there is no high-purity aged soil, but there is baux-vanadium soil in Nanping, and the main components of the two are the same, both are alumina...... Then use the above methods casually, such as vanadium soil plus quartz sand and plant ash and then stale, even black iron ore can turn you white......"

"What are you talking about, how could there be such a craft in the Yuan Dynasty?"

"I thought there weren't, but it did!"

Li Dingan stretched out his hand: "Director Zhang, what about the report?" ”

Zhang Hanguang didn't move, just sighed.

Dai Younian also sighed, and no longer observed Li Ding'an, but fell into deep thought.

On the other side of the surveillance, a room of police officers looked directly at the test report on the conference table as if they were frozen.

The characteristics of the vessel type are Song, the C-14 dynasty is Yuan, and the place of origin is unknown...... But in the composition column, in addition to porcelain clay, there are also bauxite, quartz sand, and plant ash......

In other words, is it really one of the two methods that Li Ding'an said?

So the last three words are like needles, not ordinary piercing eyes......

I'm sorry, the information is not detailed during the day, and I can't write it anymore, so I can't help it, so I can only reverse it and start over.

It's a bit short, so I'll squint for a while and then try to write when I get up.
