Zhou Wenping and Lao Wu were more convinced of Chu Chen, and besides, the real thing can't be fake, the high-handled cup in front of them is very in line with the characteristics of eggshell pottery, which can be described as "thin as paper, hard as porcelain, bright as a mirror, and black as lacquer".

"This eggshell pottery is so beautiful, I didn't expect to see such exquisite eggshell pottery in my lifetime." After watching it carefully, Lao Wu couldn't help but admire.

Chu Chen smiled when he heard this: "I said Lao Wu, it's not like you haven't seen eggshell pottery in the museum, it is necessary to say such an exaggeration!" ”

"That's different!" Lao Wu waved his hand again and again: "The museum is separated by a layer of glass, this feeling of close observation is much cooler than going to the museum!" ”

Chu Chen and Zhou Wenping nodded and agreed, after all, it was better to see it than to touch it.

"This eggshell pottery is really magical, it has been four or five thousand years down, and there is such a dazzling luster, and I don't know what techniques were used by the people at that time to make it." Zhou Wenping said with some surprise.

"I've seen the relevant information."

Chu Chen explained to the two: "According to research, the reason why the surface of eggshell pottery has such a dark and shiny visual effect with metallic luster is because the craftsmen at that time used calendering and carburizing coloring processes. ”

"The unique carburizing process penetrates the carbon molecules into the micropores of the carcass of the utensils at high temperatures, so that the surface of the carcass treated by calendering forms a more dense and smooth, delicate and smooth black protective layer, so that the eggshell pottery has been eroded by water and soil for thousands of years, and it has the effect we see now."

The two listened to Chu Chen's explanation. They nodded knowingly, but they had mastered the calendering and carburizing and coloring techniques of craftsmen who had been in the industry for four or five thousand years. They were all very surprised, and saw the thin tire of the fine man at the edge of the mouth. I feel deep admiration in my heart.

After half a ring, Lao Wu said: "I think that the cup is thinner than what I see in the museum, or I should take down the vernier caliper and measure it!" ”

Hearing the fifth child say this, Chu Chen and Zhou Wenping both felt interested, and it happened that Chu Chen had a vernier caliper in his office, so Chu Chen went to take it and measured the thickness of the rim, but this amount made the faces of the three of them show shock.

"I can't be mistaken! It's only 0.16 mm! Zhou Wenping said with an incredulous expression.

Don't underestimate the 0.04mm figure. This data can be said to be a big gap in technology, and it cannot be crossed for a long time, and this time may be hundreds or thousands of years.

It is precisely because of this that the three of them are so shocked, they really can't figure out how the craftsmen of four or five thousand years ago can do it, is it possible, what kind of alien will it really teach?

Actually, speaking of this eggshell pottery of Longshan culture. In addition to the process of drawing embryos, the selection of clay is also a difficult problem that has troubled scholars.

It is important to know that the general eggshell pottery is made of local clay raw materials. And its delicate clay particles are not more than 1 mm in diameter, so in the ancestors of four or five thousand years ago, before the silk mesh, what tools were used to filter clay? This question. There is no definite answer to this day.

Of course, it is precisely because eggshell pottery has such a mysterious color. Moreover, due to the rarity of the eggshell pottery products unearthed, the complete artifacts are less than the porcelain of the official kilns of the previous dynasties and the blue and white of the Yuan Dynasty. Plus its pleasing appearance. Therefore, eggshell pottery has a potential market demand, and the value of high-quality products is even more expensive.

The thinnest part of the eggshell pottery that Chu Chen got was only 0.16 mm, which was a data that Chu Chen had never seen before, and its value rose because of this.

Subsequently, Chu Chen was afraid that the data would be inaccurate, so he asked Lao Wu to borrow two vernier calipers, and the result was the same.

At this moment, Chu Chen's mobile phone rang, and when he saw that it was his uncle's number, he walked to the side and picked it up.

"Achen, the bald man confessed, and the person who instructed him was Liu Yu." Zhao Qirui's somewhat angry voice came from the other end of the phone.

Not to mention that Zhao Qirui felt angry, Chu Chen also felt very angry, some time ago, Liu Yu had just been locked up and confined, and it hadn't been a few days before this happened again. And it was precisely because of the misjudgment of this matter that Chu Chen's heart relaxed his vigilance, which caused serious consequences later.

Of course, Chu Chen himself is somewhat responsible for this matter, but he thinks that Liu Yu is also one of the culprits, not to mention that this Liu Yu seems to be a mad dog who doesn't remember to beat, and he comes to make trouble one after another, which is really bearable, which is unbearable!

"Achen, what do you want to do with this?" Zhao Qirui asked.

Chu Chen pondered for a while, and then said, "Uncle, let him come as painful as he wants!" ”

"Okay, I know what to do!" Zhao Qirui said: "By the way, you better hurry up and let Hu Yong come back, there is no one around you, I really don't worry, if you are worried about the kiln factory, I will send someone over to you." ”

"What a shame!"

During this time, after careful observation, Hu Yong felt that the director and employees of the kiln factory should be quite trustworthy. In this case, plus the security guards sent before, Hu Yong can also come back.

But after all, the situation over there is a bit important and special, and if someone is sent over, Chu Chen can also feel at ease, so he thought about it and responded.

hung up the phone, and after a while, Chu Chen received a call from the old village chief again, he said that on January 12th, the mountain road would be opened to traffic, and if he had time, he would go back to participate in the opening ceremony.

Hearing this good news, Chu Chen was very happy, and immediately promised the old village chief that he would definitely go back then.

With this road, the traffic in Lujia Village will be convenient in the future, and the forsythia planting plan that he asked his sister to consult can also start researching.

If the surroundings of Lujia Village are really suitable for planting forsythia, then it will not be long before Lujia Village can get rid of poverty and become rich, and then it can also drive the surrounding villages to get rich together, thinking about it, he feels a little excited.

…………

In the next few days, Chu Chen's life was plain and fulfilling, in addition to carving a jade ornament for his family, the previous gold and silver dragon pattern bronze mirror was also cleaned, when he saw the original face of the bronze mirror, his mouth couldn't help but let out an exclamation,

The craftsmanship of this bronze mirror is extremely sophisticated, and the gold and silver threads embedded in it are as thin as hairs. And what makes Chu Chen even happier is that after more than 2,000 years, most of the gold and silver filaments on it are still quite well preserved, which can be said to be quite difficult.

It was rare to see such a heavy weapon, plus Chu Yulan's wound was getting better day by day, and Yu Guangjie and Liu Yu were treated again, plus he had a phone porridge with Wu Ke every day, Chu Chen's mood completely improved again.

Soon, the time came to the eleventh, because the road in Lujia Village will be opened to traffic tomorrow, so Chu Chen must set off today, and this time in addition to Chu Chen's place, Chu Yongning and his wife and Chu Yulan will also go together.

Originally, Chu Yulan's gunshot wound was not healed, and the family didn't want her to go, but she was grinding hard and soaking, and she had a bleak face all day long.

There was nothing to do all the way, and the two cars carrying Chu Chen's family, Hu Yong and a guard finally arrived at Chu Chen's alma mater at five o'clock in the afternoon.

However, what they saw and heard on the road and the poverty in this mountainous area also made Chu Yongning and his wife feel very uncomfortable in their hearts, their son has lived in such an environment since he was a child, even if his adoptive father takes good care of him, he must have suffered a lot, which makes them feel even more guilty about Chu Chen.

At this time, the old principal, as well as the teachers and students who lived in the school, were already standing at the school gate to welcome their arrival.

In addition, Chu Chen also noticed that not far from the school, colorful flags had been floated, which should be preparations for tomorrow's opening ceremony.

After getting out of the car and greeting each other a little, Chu Chen hurriedly introduced the two parties.

Chu Yongning shook hands with the old principal and greeted, "Principal Tian, you have worked hard!" ”

He had heard about the old principal's deeds from Chu Chen before, and such a principal who was dedicated to his students was indeed worthy of admiration.

"Where, where!"

The old principal had already learned Chu Yongning's identity from Chu Chen, although he had seen a lot of officials, but Chu Yongning's level he really hadn't been in contact with him, and he felt a little nervous in his heart, after listening to what Chu Yongning said, he hurriedly said: "Secretary Chu, I'm nothing, you have a lot of opportunities to call it hard work!" ”

Chu Yongning smiled and said: "Principal Tian, you are humble, your job is to cultivate the future of the motherland, this work is indispensable to the country, there is no difference between us!" ”

"Don't dare to be! Don't dare to be! The old principal was still very nervous, and then he didn't know what to say.

In order to avoid the embarrassment of the old principal, Chu Chen hurriedly said: "Uncle Tian, why don't you let the teachers and classmates go back, I'll take my dad to take a look at the school." ”

"Good, good!"

The old principal nodded again and again, and then he asked the teachers and students to go back first, and he accompanied Chu Chen's family to visit the school.

On the way back to the dormitory, because of the old principal's title to Chu Yongning and his reaction, those teachers speculated one after another about what kind of big man Chu Yongning was, some said he was a department-level cadre, and some said he was a department-level cadre.

"I think it should be at least a ministerial-level cadre!" A female teacher said.

"Ministerial-level cadres?" Others were a little unconvinced.

"Why, don't you believe me?" The female teacher explained: "It's very simple, it's not that our principal hasn't seen department-level cadres, how can he be so nervous? And don't you see, there are two bodyguards next to it, if it's not a big official like a ministerial-level cadre, how can there be a bodyguard? (To be continued......)
