"I am a typical grassroots background, with my own efforts and ability to become the chief expert of the Beijing Museum, from beginning to end without getting the advance of others, completely by my own blind exploration. At least you have me as a master now, and you can take fewer detours than others. Lin Lao said with a smile.

Liu Tao didn't speak, just nodded.

"You're really a student now, and you're still acting recklessly. Whether it's the Smurfs or the Blood, if it weren't for me to help you block it, I'm afraid you wouldn't be able to keep these things. Especially the blood Linglong, it is definitely not one or two people who want to get it, and they are all people with a very good background. Now someone has come to me to talk about the bloody thing and wants to pay a high price for it. If I hadn't insisted on not selling, I'm afraid they wouldn't have given up. Ah Tao, you should pay attention to low-key behavior in the future, especially when you have good things, you must know how to hide your secrets. When you really have what it takes to protect these things, take them out. Otherwise, it's just adding to your troubles. Lin Lao said earnestly.

"Master, I'm sorry, I caused you trouble, I will definitely pay attention to it in the future." Liu Tao said with some embarrassment. To be honest, he is still a little young now, and sometimes he does things just to fight for a breath. It is precisely because of this fight that many people end up with a broken family. The most typical example is Shen Wansan of the Ming Dynasty, the richest man in the dignified world, in order to fight for a breath, finally beheaded all the door, which is really regrettable.

"Alright. Let's start learning. Lin Lao casually picked up a jade plaque and asked Liu Tao to hold it himself.

As for the quality of jade, Liu Tao just learned some theoretical knowledge, and it is probably still a little difficult for him to really judge what jade quality is. But for him, none of this is difficult. Because he has the obvious advantage of being able to see through. As long as he can see through, he can continue to look at all kinds of jade qualities, memorize their characteristics, and then match the jade quality that has been determined by experts in this piece of jade, and it won't be long before he can complete the judgment of jade quality.

Liu Tao looked at it for a while. I involuntarily used the eye of the sky to scan the jade plate, and my eyes opened widely.

He had expected to be able to see what was inside, but it turned out that he couldn't see it clearly. Willingness is very simple, and the jade plate is not hollow. The entire internal structure is consistent. However, to his surprise, he saw a blue mist of light emitting from it, but if you looked closely, it should be five layers of blue light, like the rings of a tree. Round and round. It's just that he really doesn't know what these apertures represent now, and he needs to explore them slowly.

"Master, when did this jade plaque come from?" Liu Tao turned his head and asked Lin Lao.

"This is the Zigang jade plate, which is a work in the late Qing Dynasty." Lin Lao smiled and said.

"Oh? This jade plaque was not carved by Lu Zigang? Liu Tao was stunned for a moment, and then asked. He has read the information and knows that Lu Zigang was a very famous master carver in the Ming Dynasty, and his works have not been handed down much.

"There are not many Zigang jade plates carved by Lu Zigang himself. Basically, it's in the major museums. Most of the ones circulating on the market now are imitated by the people behind them. In fact, this kind of behavior is also a kind of respect for Lu Zigang by many people who are keen on carving, and some of them are quite good. For example, this piece was made by a famous carver in the late Qing Dynasty. Lin Lao patiently answered.

"I see. Master, according to what you say, the jade used in this jade plaque is also from the late Qing Dynasty? Liu Tao then asked.

"Yes. Jade was basically mined back then, and it was used to make jade carvings back then. Lin Lao said.

"Master, can this jade plate determine the exact mining time?" Liu Tao then asked.

"Yes. However, there are still errors. If you use the method of carbon 14 attenuation for reverse reasoning, it can almost be deduced, but the positive and negative errors are 50 years. Lin Lao explained.

"I'm dizzy! Master, how many years has the late Qing Dynasty been away from us now. Fifty years plus or minus is too big an error. ”

"This method of detection is still mainly used for some older items. However, there is a downside to this approach. That is, there will be some damage to the item. It is precisely because of this shortcoming that many older items do not dare to use this method, so the identification of antiques now mainly depends on people. Lin Lao said with a smile.

Liu Tao sighed and said he understood. Then move on to other collectibles.

This time he picked up an inkstone. Scanning of the eye of the sky. He found that inside was a seven-and-a-half-layer blue aperture, and the other half of the aperture was colorless.

It seems that this is indeed very strange.

"Master, when did this inkstone come about?"

"This inkstone is a work from the middle of the Qing Dynasty." Lin Lao said with a smile.

When Liu Tao heard about this period, his heart moved. It seems that these apertures are indeed strange, and they are all a kind of record of life history, just like the annual rings of trees.

Middle Qing Dynasty. That is, the period from 1730 to 1820 AD, the late Qing Dynasty, that is, from 1820 AD to 1910 AD. The difference between the two time periods is almost a hundred years.

If this is calculated, the extra two and a half revolutions should be equal to one hundred years.

In this way, one aperture should be equal to forty years.

Of course, this is only a preliminary extrapolation. After all, there is no exact year for the two items, and it is necessary to continue to do the real yàn.

"Master, which of these collections of yours have exact dates?" Liu Tao looked around and asked.

"There are estimates of only about 20 pieces of the year, and the rest are known for the approximate period." Lin Lao said.

"Then I'll look at the vintage first, so that I can better understand some of the characteristics of these collections." Liu Taojian said.

"No problem." Lin Lao nodded and found the collectibles that had been marked with the year.

Liu Tao saw that the more than 20 pieces of the collection basically included various relatively large dynasties from the Western Zhou Dynasty to the modern period, which would be of great help to his research.

Then, Liu Tao went to the study to find paper and pens, ready to start recording.

Lin Lao saw that he was so energetic in learning, so he didn't bother him here at the moment, and when he was here, he pondered by himself for a while. Then he left lightly.

Liu Tao is now fully immersed in research.

He constantly used the eye of the sky to see through one by one, and then recorded the number of aperture layers and colors in it one by one.

As time passed, he felt that his eyes were a little uncomfortable, and when he looked inside, the number of apertures was not so clear, so he had to stop for a while. (To be continued.) )
