Chapter 46, learned from the book
Seeing that Shang Yan remained silent, Wang Qizhi smiled again: "Aren't you shocked?"
Shang Yan opened her lips as if to ask something, but then pursed them into a thin line.
Now, it's no longer a question of whether Lin Sicheng understands or can do it, but rather why he is so professional.
Everything else is easy to talk about, especially the last point. To put it simply: how does he find the right balance range when he needs to measure both copper and glaze?
To put it more technically: Cloisonné has a copper base and a glaze surface. During testing, the Cu-Kα peak in the copper base can interfere with the values of low-content elements in the glaze layer. Therefore, it is necessary to use a collimator to shield the base signal.
Therefore, Lin Sicheng's last sentence instructing Li Zhen to set the parameters is particularly important: Collimator selection: 150μm, spot size range: 0.5-1 mm...
She could certainly calculate this value, and so could Wang Qizhi, but the prerequisite was that software had to be used for the calculation.
But Lin Sicheng could just spout off without thinking?
If you think this value is wrong, look at the signal acquisition: whether it's the elemental peak, the characteristic peak energy, or the standard half-quantitative and standard quantitative values, the values are more and more accurate.
Why didn't Lin Sicheng need to calculate in advance to achieve such precise balance values?
Unless he has conducted similar experiments thousands of times, to the point where he can determine the thickness of a specimen's body to the precision of 0.1 millimeters with just a glance, and simultaneously estimate the percentage of corrosion on the base to two decimal places.
But then another problem arises: cloisonné enamelware, from the Jingtai period of the Ming Dynasty to the Guangxu period of the late Qing Dynasty, was always an imperial artifact. Due to the limited number of specimens, specific usage scenarios, and regional limitations, only a handful of research institutions in Beijing could study it.
So where did Lin Sicheng get hundreds or thousands of experiments from?
Anyway, Shang Yan figured she definitely couldn't do it, she didn't know if Wang Qizhi could, and Professor Lin... probably couldn't either.
This is completely outrageous...
Where did he learn that?
"In the book!"
Shang Yan suddenly looked up: "Huh?"
"He said it was in a book... Professor Shang doesn't believe it either, right?"
Wang Qizhi smiled and said, "A couple of days ago, he sold me an iron token. He said he could clean, maintain, and even repair it, but I didn't believe him..."
Then, he used the ultraviolet-infrared imager in my lab to perform a surface penetration imaging acquisition of the iron specimen…
After a slight pause, Wang Qizhi looked at Shang Yan and asked, "Professor Shang, do you know this method?"
I don't know anything about that. That's a method for testing iron. Why would I, a ceramics researcher, need to learn that?
Shang Yan rolled her eyes: "Professor Wang knows?"
"I don't know either, because the relevant papers were only published by the Chinese Academy of Social Sciences last year..." Wang Qizhi said frankly. "Besides, I'm a copper researcher, and I can't even keep up with the learning in my own field, why would I need to learn iron testing methods?"
yes?
Just as the two words reached Shang Yan's lips, Wang Qizhi pointed inside:
"But he would... I asked him where he learned it, and he said from a book! I didn't believe him, so he pointed out the relevant papers published by the Chinese Academy of Social Sciences, the National Museum of China, the State Administration of Cultural Heritage, Beijing University of Technology, and other institutions one by one... He even asked me if I wanted him to recite them for me?"
Shang Yan stared blankly: Isn't this bullshit?
"Professor Wang, I remember the iron artifacts research project... was only approved last year?"
"Yes, that's why those papers were concentrated in the second half of last year... But that's secondary... He was preparing to prepare acid to clean the rust, but after I scolded him and drove him away, he sent me a whole set of maintenance procedures related to desalination, dechlorination, corrosion inhibition, and sealing..."
Then, here's the key point: I sent it to a friend in Beijing, and he told me: This technology was only patented by Beijing University of Technology at the beginning of the year, and the National Museum of China and the State Administration of Cultural Heritage are still in the trial stage..."
Wang Qizhi shrugged: "My friend even asked me where I stole it from?"
"I asked him again where he learned it, and he said the same thing: from a book... Of course I don't believe him! But if you ask me to give him another reason, I really can't."
Wang Qizhi sighed again: "Including before, he said he could repair the cloisonné, but I didn't believe him. Then he asked me: 'No matter how difficult this plate is to handle, can it be more difficult than that iron certificate?'"
"I thought about it, and it really makes sense... so here we are!"
Shang Yan stared at the figure in the equipment room, her eyes widening little by little.
Although there are few institutions that study cloisonné, this is only relatively speaking, and the level of expertise among them is quite high.
However, there were virtually no institutions researching ironware.
The reason is simple: technological gaps lead to lagging technological research and development, making it impossible to apply what has been learned and generate benefits, thus entering a vicious cycle.
That's why the government introduced relevant support policies and even included it in the "Eleventh Five-Year Plan Key Social Science Fund Project".
Even if the project is approved, it is only in its initial stage. Apart from academic papers and journals, there are no related monographs yet. From which book did Lin Sicheng learn?
Unless it's derived from a research paper, but honestly, if you're that good, why bother reading books?
The State Administration of Cultural Heritage and the Institute of Archaeology of the Chinese Academy of Social Sciences can enter whichever they want.
Wait a minute... something's not right?
Shang Yan was stunned for a moment: "What iron certificate, a Dan Shu Iron Certificate?"
"Yes, the iron certificate of immunity from death that Li Zicheng granted to Lin Yangcheng... Just the weekend before last, I saw him pick it up at Xiaodongmen with my own eyes. He spent forty and sold it to me for five hundred thousand... Oh, and that plate too..."
Wang Qizhi pointed into the equipment room again, "He bought a dog yesterday, and this dish was used as a dog bowl, so he didn't spend a penny... But he sold it to my older brother for a full 800,000 yuan, plus commission, it was 940,000 yuan..."
"Also, on the first day I met him, he found a reference book, spent thirty, and sold it to me for ten thousand... Oh, and he also found a feather duster, sold it for eighty thousand, and found a Buddha statue, sold it for three hundred thousand... You, my teaching assistant, should know about these two things."
Professor Shang, do the math: ancient books, ironware, bronzeware, calligraphy and paintings, wood carvings... just from the perspective of the attributes of antiques, how many categories does he span?
So, these past few days I've been thinking: Professor Lin is undoubtedly very professional in both ceramic research and appreciation. But even if he surpasses his teacher, can he really surpass him to this extent?
But guess what he said: "Apart from porcelain, the rest has little to do with Professor Lin; he learned it all from books..."
Shang Yan moved her lips, wanting to say something like: If the knowledge in books is so easy to learn, what's the point of having teachers?
Li Zhen did mention that she personally witnessed Lin Sicheng picking up a duster and a Buddha statue, which were eventually sold for 380,000 yuan. But little did she know, there was much more that Li Zhen was unaware of.
Adding all of these together, how much is it? A full 1.69 million... The key point is, all in just over two weeks?
Although talking about money in an ivory tower is considered vulgar, do people in an ivory tower stop eating and drinking?
Her annual salary, bonuses, and project subsidies total a little over 40,000 yuan. She's 45 years old this year, and if she didn't eat or drink, she'd have to work for another 40 years...
If she were Lin Sicheng, would she even bother with a master's degree?
