Treasure Hunting Divine Eyes

The applause in the classroom was almost uninterrupted. Although Li Mo was about the same age as them, his accumulation of knowledge was indeed deeper than theirs, and the two sides were not on the same level.

After Li Mo answered the question about He's Bi, he said, "Do you have any questions from my classmates?"

"Teacher, I have a small request?" A pretty girl sitting in the back raised her hand, and she took a pendant from her neck, "Can you please help me see if this jade pendant is it is true?"

This is to test his ability to appreciate jade on the spot.

Li Moxin said that if you don't come up with some means, you are still not convinced. He walked to the back and reached out to take the jade pendant that was passed on. He just glanced at the girl and asked, "Who gave you this jade pendant?"

"My boyfriend said it was passed down from his family. It has been passed down from generation to generation since the Republic of China."

"Your boyfriend is also a student of Peking University?"

"That's not true, he's at another university in Kyoto."

Li Mo returned the jade to her and said: "We generally talk about jade. There are old jade and new jade, and there are good jade and bad jade. If the jade pendant in your hand is really handed down from the Republic of China, it is old jade. That is ancient jade, unfortunately, the jade in your hand will not be completed for more than a year."

There was an uproar in the lecture theater immediately.

"Impossible, look at the color in this jade pendant. My boyfriend said that it would take at least a hundred years to form such a color effect."

The girl frowned, suddenly a little unhappy.

"Student, don't worry, I haven't finished my sentence yet. Your jade is not only new, but also inferior, with mediocre quality. As for the color you mentioned, it was artificially made." Mo walked back, and said as he walked, "Everyone is a master of learning, and there are many things you don't understand, but you will suddenly realize it when I dial it. As for ooze, from a physics point of view, it is a kind of material due to Molecular movement penetrates into the jade to form the effect, this kind of penetration is irregular, the deeper it is, the weaker the penetration effect of the material molecules, everyone can understand this phenomenon, right?"

This is very clear, who can understand, isn't this doubting their IQ?

"The female classmate, please take a closer look at the jade pendant in her hand, and see what is the characteristic of the color inside it?"

Not only she was watching, but the students in the front, back, left and right all stretched their heads to see.

"Does it look like it was made artificially?"

"Really, you can see that the color of this jade pendant is almost formed in pieces, with a certain pattern, and the color distribution is unnatural."

"I'll go, your boyfriend is too thieves, it's just delusional to take a piece of broken jade and try to trap our talented girl in Kyoto."

"Sister, hurry up and break up with your boyfriend, we have a lot of talents in Beijing University."

The female classmate sat down on the chair with an ugly expression, and stuffed the jade pendant into the small bag she carried.

Li Mo returned to the podium and reminded him kindly: "Student, the color in your jade pendant is a kind of chemical substance, so it looks very rich and beautiful on the surface, but wearing it for a long time will affect the human body. Healthy. If you wear it next to your body, it may also cause skin diseases. Of course, if you still have doubts in your heart, there are many experts in our history department, and you can ask them for advice.”

"No teacher, I believe what you said. I have been wearing this jade pendant for about a month, and the skin on my chest has always had small red spots. It only relieves it after applying ointment, and it will continue to attack once I don't apply it. Now it seems , it was all caused by this bad jade."

"In that case, let's move on to this topic. In fact, my special subject is porcelain, but so far, we haven't returned to this important topic. The next student who asks a question should pay attention, and don't deviate from the normal track."

Li Mo opened the lesson plan. If no one asked any more questions, he would throw out one or two points of view and focus on the knowledge points about porcelain.

"Teacher, can I ask a question?"

A small girl student on the far left in the first row raised her hand timidly.

"Of course, what do you want to ask?"

"I know an elder who has a tri-colored Tang Sancai in his family. Several experts identified it as a fake, but my elder denied it and insisted that his own is a genuine Tang Sancai. The reasons why those experts identified it as a fake It’s the same, saying that the Tang Sancai in my uncle’s hand is porcelain, not pottery. If I want to ask, is Tang Sancai pottery or porcelain?”

Li Mo looked at the girl meaningfully, and it seemed that the elders she was talking about were probably close relatives. However, he did not break the casserole to ask the end, but replied: "First of all, I would like to remind you that if the Tang Sancai in the hands of your elder is genuine, it is of amazing value. Before it is finally confirmed whether it is genuine or fake, it is still Protect it."

"Before answering this student's question, we must first understand the difference between pottery and porcelain, and what is the connection between them? In fact, even if this question is not raised now, it will be emphasized in later courses."

Li Mo opened the mineral water and took a few sips, then said: "Porcelain is derived from pottery, and is good at pottery. The biggest difference between porcelain and pottery is that they are fired at different temperatures. Pottery is fired at low temperature, while porcelain is fired at a low temperature. It is necessary to reach 1200 °. If the temperature is lower than this, it is pottery, and vice versa. Because of the huge difference in firing temperature between the two, the porcelain effect on the surface is also significantly different."

"Then whether the Tang Sancai is pottery or porcelain. According to the unearthed samples and some documentary evidence, the Tang Sancai belongs to low-temperature pottery. Green, white, brown, blue, and black, among which yellow, green, and white tricolor glazed pottery is more common."

"As for the authenticity of the Tang Sancai in the hands of your elders, further identification is needed."

Li Mo missed such a good thing, but Tang Sancai only came across one, and the damaged one was dug out from the warehouse in Beijing. It was a pity, but it also reflected the rarity and preciousness of Tang Sancai from the side.

"If there is no further question, then I will continue to talk about the topic just now." Li Mo coughed lightly, "I just talked about the difference between porcelain and pottery. When did porcelain start to flourish? It was in the Song Dynasty , the Song Dynasty had the five most famous official kilns in history.”

Everyone was fascinated by his explanation.

Time passed quickly, and as the bell rang, a short public class ended.

"Everyone, my course will officially start next week. If you are interested, please register as soon as possible and leave get out of class."

Li Mo picked up the lesson plan and walked out of the lecture theater with a smile on his face, and the professors and teachers who were watching the live broadcast in the next classroom also came out.

"Mr. Li, this public class is very good. I remember that when I took the first public class that year, I was so nervous and my back sweated." Professor Zhang said approvingly, "Your performance is far from Exceeded our expectations."

"Old Zhang, you're alright. After I took a public class back then, I lay down at home for a whole day before recovering."

Zhu Changping also thought about what happened when he first became a lecturer, and he patted Li Mo on the shoulder lightly: "You did a good job."
