Live appraising treasures, I became a national treasure expert?

The metaphor is not very appropriate, but the principle is the same.

Follow the normal experimental procedures: first visually identify the type, approximate time period, general composition, and main ingredients of the tool, and then discuss the corresponding experimental plan.

Then, based on the storage environment, oxidation and corrosion levels, a suitable experimental plan is formulated: whether to do spectral energy storage and release, radioactive element half-life, trace element conversion, or magnetic field age evolution.

Sometimes, samples with the same ingredients at the same time period require completely different experimental methods and techniques. Even the same artifacts excavated from the same tomb are sometimes found using different experimental methods.

Because the depth of excavation is different, the strength of corroded acid and alkali is different.

There are many experimental methods, and the applicable instruments are even more diverse. If the number of samples is enough, it will be better, and you can continue to try and make mistakes. If the samples are insufficient, you need to continue analysis and dialectics to determine the best solution.

In related research institutions, it is really common to prepare for an experiment for a week.

And now?

There was no discussion, no analysis, no dialectics, and no one was asked for opinions. It was all decided by his words.

Especially starting from the second brass flower goblet: peeling off the shells of copperware, scraping glaze powder on porcelain, drilling holes in fetal feet, soaking ancient jade in strong acid... all are destructive sampling methods, which means that after the experiment is completed, the things will be useless. .

Let’s not talk about whether it should be abolished or not. What if the method is wrong?

But there is no place to look for the second one, and even if you want to correct the error, you can't.

More importantly: should the initial inspection and re-inspection be conducted at the same time?

Laymen may not understand it, but people who know research know what it means: the second experiment is the final inspection, and conclusions must be drawn based on the experimental data.

In other words: re-examination is the final result, even if it is wrong, you have to treat it as right...

The strange thing is that no one expressed any opinions?

Ma Xianming acted vigorously and resolutely, and he asked the researchers to prepare the corresponding instruments and reagents according to Li Ding'an's arrangements.

Several researchers worked non-stop: turning on the computer, preheating, finding utensils by number, taking samples...

"Secretary-General He, I admire you... If you want to be professional, it has to be you."

"what?"

He Anbang was playing with the ancient jade, as if he still didn't know what was going on. He raised his head blankly: "President Shen, what did you say?"

"I'm talking about experiments: there is no need for micro-sample testing, no analysis, and no need to make an experimental plan. You can just take samples directly, and then you can directly put them on the machine, or even do six groups at a time... leave us alone, just prepare at least It’ll take two weeks!”

What you said was ironic, right?

No procedures, no plans, not even a rough outline, just open your mouth and do it with your head covered...

If this was Lao Ma, He Anbang went up with his fist in hand: Come on, open your eyes wide and take a look, what's on the wall?

You can't see the big words, and the system and regulations are eating you up?

But if it's Li Ding'an...well, as long as you're happy...

He Anbang thought for a while: "We don't do this often. Most of the time, we still have to meet on site, discuss methods, and formulate plans... We can't do as many as six groups at a time, at most two groups!"

"That's pretty cool: you can come to a conclusion twice, and this is the first time I've seen it?"

So what if?

Not to mention you, before meeting Li Ding'an, who would have dared to imagine that the experiment could be done like this?

He Anbang understood that Director Shen was really surprised, not sarcastic.

He scratched his chin and didn't know how to explain: "It's okay, he has experience!"

experience?

Suddenly, President Shin could no longer speak.

He raised his neck and looked at it again: Yes, there are not many beards?

Where did he get his experience?

Several professors with provincial PhDs were nearby, looking confused as they listened: Director He said that national museums usually don’t do this, and they still need to discuss plans and make plans... Does this mean that this is unusual?

There is no difference, right? Even the batch with poor experimental environment cannot even achieve the most basic dust-free. The experimental data can be imagined...

Not only did they not understand, but they also didn’t understand: Yao Chuan and Cheng Yongquan are both senior researchers and well-known in the industry. No matter who goes to a provincial-level museum, they come with a guiding purpose, and there is no dispute.

But now, they do whatever the young people say, obey their orders, and act with caution and without any compromise.

There is also Ma Xianming, who is an authority among the authorities in the field of art research, but now he is like a follower. He follows the young man wherever he goes. He is more like a yes-man. Whenever there is a hint of explanation, he will immediately implement it.

He Anbang even acted as a hands-off shopkeeper and didn't even look at him.

This person can't be more authoritative than them, right?

Li Ding'an...haven't you heard of it at all?

The age is also wrong: it's possible to be twenty or thirty years old, but with this look... it looks like someone from a youth idol TV series?

But slowly, they came to their senses: it’s not that the world is too crazy, but that they themselves have too little experience...

As time passed, Li Dingan stood behind the two experimental groups with his hands in his pockets. He didn't move, but reminded him from time to time: "Teacher Cheng, the radiation intensity is too low, it should not be lower than six thousand uncles..."

"Team Leader Yao, the order of exposure wavelengths is wrong: UV first, then near infrared..."

"Teacher Hong, the temperature of the disinfectant is 25 degrees. Your ratio should be at least 30. Cool down..."

"Teacher Mao, adjust the frequency of light quantum..."

No matter who he mentioned, the researcher would laugh first, no one would argue, no one would question, and they would immediately check.

This is normal, because experimentation is a process of constant trial and error and correction, and oversights and errors are inevitable.

It is normal to accept it humbly and correct it immediately.

But what is abnormal is the question that Li Ding'an reminded: Just look at the instrument for radiation intensity and wavelength. But the disinfectant has just been prepared and has not yet been measured. How does he know what the degree is?

Teacher Hong took another thermometer and looked at the temperature: no more, no less, just thirty degrees.

The onlookers looked at each other in confusion, as if they had seen a ghost: Isn't this a bit unscientific?

After much deliberation, there is only one possibility, physical derivation: add how much strong acid and how much water, and then calculate it based on the indoor temperature.

But to be honest, let alone verbal arithmetic, it would take seven or eight minutes to give them a computer and formulate formulas. Li Ding'an just took a look and blurted out, and it didn't even take seven or eight seconds.

No, does your vision come with a built-in temperature measurement, or does it come with a built-in capacity scale and random calculations?

Gradually, they came to understand: Why did Li Ding'an not talk about any procedures, didn't make any preparations, took samples when he was told, and put on the machine when he was told, but no one questioned him?

His eyes are like laser electronic instruments. No matter which person in any group is the main tester or the assistant tester, if there is a problem, the experimenter has not discovered it yet. He can point it out at a glance and make corrections at the same time. direction.

The brain is like a computer: the experimenters are still weighing how to calculate and which set of formulas should be applied to minimize the error. Li Ding'an has already begun to deduce. The answer range can be given in as little as tens of seconds or as long as one or two minutes.

The memory is even scarier:

Because of his on-site guidance, the progress of the experiment was as fast as flying. Fang Zhijie was sweating so anxiously that he was typing on the keyboard like exploding beans, but the data retrieval speed could not keep up.

Then Li Ding'an will tell him which catalog, which category, which journal, which paper, as well as the publishing unit, the author of the paper...

The deputy director of Hebo and several professors almost had their eyes popping out: After half a lifetime of research, this is the first time that they can’t keep up with the experiments through retrieval?

Others don’t know that if it were given to them, they wouldn’t be able to copy it so quickly.

Looking at it the other way round: No wonder everyone from He Anbang to his assistant has this attitude?

If they had such a person in their family, they could support him like a father...

"What's the talent?"

Director Shen's eyes gleamed, "Which organization are you from, the Chinese Academy of Sciences, the Industrial Research Institute, or the Academy of Social Sciences?"

"No, it's from the National Expo!"

"Where did you dig it from?"

"I didn't dig it, it just came out by itself!"

Nonsense...can you try a few more for me?

Director Shen bulged his eyes, looking like you should stop fooling me.

He Anbang smiled reservedly and said no more.

He wasn't lying either: after having dealt with him for so long, I only knew that this guy had a ridiculously strong eye and a frightening level of appreciation. I didn't even know that he could do research.

He is a liberal arts student, and he has just graduated. His salary is 800 yuan, which has nothing to do with research. Until he came back from XJ and brought Mongolian porcelain...

Therefore, it really just came out of nowhere, and it was inexplicable and caught off guard: If it had been a few days later and Li Ding'an had gone to Beijing University to report first, how could it be the National Expo's turn?

……

A group of professors were frightened, and Qu Zhongshu was also shocked.

"No...isn't he a student?"

"That's right, graduate student at Peking University, second year graduate student!"

“Are the students from Beijing University so awesome?”

"I'm not sure. It should only come out in a few years... Anyway, it's pretty awesome!"

"Is he still a special agent of your bureau?"

"Of course!" Zhang Hanguang raised his chin, "You think you're not qualified?"

Not qualified enough!

With this speed of experimentation and this research capability, isn't it equivalent to bringing a testing center with you?

Not only is it fast, you can check it as you want...

"The second generation of research, or the second generation of science?"

"This is really not true!"

Zhang Hanguang shook his head, "He is from a local family. You may know his father, Li Ruying from your city library!"

"Director Li from the Municipal Party Committee Office... No, where did Li Ruying get 100 million?"

"What's wrong with his brain? He earned it himself..."

That's 100 million, not 100 yuan...

"One hundred million is nothing. He made more than one billion in more than half a year..."

As if he was punched head-on, Qu Zhongshu couldn't even turn his eyes: Are you talking about Ming coins?

Zhang Hanguang let out a "chi" and was about to boast a few words when he saw Li Ding'an opening a box and taking out the door curtain.

Do we need to study this too?

Zhang Hanguang subconsciously walked over. After taking a few steps, he suddenly stopped again: Li Ding'an actually picked up another pair of scissors?

Good guy...what is this for?

……

Twenty-six items are not much, but Li Ding'an spent a full 100 million.

Six million jade bamboo sticks, nearly thirty million for six pieces of Han jade, twenty-two million for Yousai, and twenty-eight million for door curtains.

The remaining seventeen items total only 14 million.

The most expensive thing is this door curtain.

Three meters square, the tapestry has a yellow background, but it is heavily polluted. Now it is almost black in color and the pattern is blurry. You can vaguely see a dragon embroidered in the center with a golden bead in its mouth.

No need to guess, it was used by the imperial court of the Qing Dynasty!

But this thing is not that rare.

There are many pieces in the Forbidden City, several in the National Museum, Shenyang Forbidden City, and Bay Island Forbidden City, and there are quite a few circulating in the world.

There are various patterns, including dragons, phoenixes, auspicious clouds, auspicious animals, flowers and plants.

The textures are varied, including cotton, leather, embroidery, weaving, and brocade.

This piece is brocade, and it is the best of brocades. Kesi Kujin: raw silk mixed with gold thread.

It's very thick, Zhang Hanguang estimated, at least five or six layers.

It's quite heavy, about 12 or 3 pounds.

But he couldn't figure it out: Even if it was all made of gold wire, it would never be so expensive.

It’s not like you haven’t taken any photos before?

In 2018, Rong Baozhai photographed a summer curtain, cooked silk cloud brocade, and a dragon with four elements in the capital, and it only cost yuan.

But it was very small, one meter square, and only had two floors.

The one made of tapestry and mixed with gold has also been auctioned. In the summer of 2020, Christie's Spring Auction was about the same size as this one: a three-meter-square tapestry with a gold price of just over million.

It is thicker than this one, with eight layers. It is also heavier than this one, 8.5 kilograms. It is several times higher than this one: the Kowloon pattern is clear.

And it is well documented: the bottom edge is woven with the words "Suzhou Weaving Chenxing" and "The Twelfth Year of Qianlong". According to research, it is the winter curtain of the side hall of Qianqing Palace.

And what about this one?

It's so dirty that most of the things dug out from the tomb are the door curtains of the underground palace...

Intuition is not worth 30 million, but Li Ding'an had winked before, so it was probably weird.

The problem is, he actually took a pair of scissors and prepared to cut it?

With this cut, let alone 30 million, no one wants even a zero...

He took two steps quickly and stopped in the middle: "What are you doing?" "

"Taking samples?"

Give me your hammer?

Zhang Hanguang pointed to the stains on it: "Do you know why this thing is so dirty?"

Li Ding'an glared at him: "Nonsense!"

It is gold that turns black when it encounters lead, and then contaminates the silk, but it is destroyed as soon as it is washed, so it can only stay so dirty.

"Even those who sell antiques know that they will be useless once they are washed. You are an expert, and you are just one of a kind: once you cut them off, who else will you sell them to?"

"Sell it to Lao He!"

Li Ding'an gritted his teeth and smiled, "Believe it or not, even if I cut it open and asked him for 30 million, he would stumble without even hitting him..."

"Thirty million for what?"

Before he finished speaking, He Anbang came over and saw the scissors in his hand. He was startled for a moment and glanced at the door curtain on the table.

"You want to cut it?"

"How can I take a sample without cutting it? How can I do an experiment without taking a sample?"

Li Ding'an said matter-of-factly, "How can we determine the age without conducting experiments?"

"Then sell it to me for another 30 million, right? I haven't been kicked in the head by a donkey?"

Okay, no, right?

Don’t be the best…

Li Ding'an smiled: "Don't worry, I'm measured!"

Before he finished speaking, there was a "click" and a hole as big as a palm was cut open in the door curtain.

Zhang Hanguang's heart also jumped: bastard, do you really want to cut it?

This is thirty million... (End of chapter)
