"So many people are watching? Are you trying to prevent Professor Xiao from coming to the stage?"
Wei Qingshu stared and asked.
Luo Zhongbao spoke righteously: "Dean Wei, I'm not messing around."
"Since he is a professor at our college, doesn't he even know how to identify antiques?"
"If he doesn't even have this ability, what qualifications do he have to teach us?"
Wei Qingshu's face turned dark. This was his biggest headache.
It's hard to offend both sides, so being caught in the middle is a dilemma.
Luo Zhongbao is a son of a wealthy family. When the college established the museum, he received several million dollars from it. It would not be good if he was criticized deeply.
"Zhongbao, let me appraise it for you."
Wei Qingshu had no choice but to take action himself.
He picked up a magnifying glass and looked at the vase carefully. The more he looked at it, the more excited he felt.
"That's right, this is Yuan Qinghua."
"It is still a rare item from the late Yuan Dynasty and is very valuable for research..."
The two teachers looked embarrassed. They said they were fakes before, but now they are ashamed of themselves.
Just as Wei Qingshu was boasting, there was a crisp sound, and the Yuan Qinghua was thrown to the ground by Xiao Feng and broke into pieces.
This scene shocked everyone present, even Wei Qingshu was stunned.
The lecture theater was quiet, and the students all stared wide-eyed.
"I...my Yuan Qinghua..."
Luo Zhongbao was dumbfounded and suddenly let out a roar.
"Asshole, how dare you break my antiques? I can't even afford to pay for it if I sell it to you."
Wei Qingshu was also angry: "Xiao Feng, what are you doing?"
"This is Yuan Qinghua. You are deliberately destroying cultural relics. Oops..."
"Dean Wei, don't worry!"
Xiao Feng narrowed his eyes and smiled, looking at Luo Zhongbao.
"Boy, you brought a defective product to fool the school and deliberately made things difficult for the teacher. What do you mean?"
What? Defective product?
Everyone was shocked and even more confused.
"Nonsense!"
Luo Zhongbao stared angrily: "This is a genuine blue and white porcelain from the Yuan Dynasty. How dare you say it is a defective product?"
Wei Qingshu's face turned green with anger and he immediately asked.
"Professor Xiao, I have identified it and it is indeed Yuan Qinghua."
"You actually said it was a fake? Please give me a reasonable explanation, otherwise I will pursue it to the end."
Even if you donated two boxes of official kilns from the Qing Dynasty, you can't do anything random?
"Okay, then I will give you an explanation."
Xiao Feng knelt down, picked up a few fragments, and threw them on the podium.
"First of all, I want to correct you. I never said it was a fake, but a defective product."
"What is a defective product? Because the upper part of this Yuan blue and white piece is authentic, while the lower part is an imitation."
"To put it simply, this is a synthetic product that was repaired with Yuan blue and white flowers during the Republic of China period."
"What? Synthetics?"
Everyone was shocked, even Wei Qingshu was stunned.
This half-real, half-fake synthetic product is extremely rare and requires extremely high craftsmanship.
"Huh! That's just nonsense. Are you awake?"
Luo Zhongbao said sarcastically: "Even Dean Wei said it was genuine, but you said it was synthetic? What kind of trick are you playing?"
"Professor Xiao, don't talk nonsense. Do you have any evidence?"
Wei Qingshu asked hurriedly.
"certainly!"
Xiao Feng pointed at the fragments and Feng Qingyun explained.
"Dean Wei, this kind of half-true and half-false cultural relics are the most difficult to distinguish between authenticity and authenticity. You will understand naturally if you take a look inside."
"There will be traces of re-firing inside, which cannot be covered up."
Wei Qingshu quickly picked up the magnifying glass. He took a closer look and was suddenly shocked.
The other two teachers were also observing carefully, and they both took a deep breath at the same time.
As expected, there are indeed subtle traces of firing on the inside of this vase.
If it were blue and white porcelain formed in one piece, there would never be such white spots, which were obviously added later.
If the vase hadn't been broken, it wouldn't have been visible from the outside.
Xiao Feng continued: "Look at the patterns on these fragments. Although the painting techniques and colors are basically the same, there are still subtle differences."
"The production process of Yuan blue and white porcelain is not complicated, and it is not even the pinnacle of blue and white porcelain."
‘Crack!’
Xiao Feng put the two fragments together and asked several people to observe them carefully.
"Look here, there are slight traces of polishing."
"Explain that this is a pattern that was added later, and the top is the original blue and white pattern."
Several people had doubts on their faces, looking at each other and not being completely sure.
But the patterns on these two fragments are really slightly different.
"Dean Wei, you don't believe his lies, do you?"
"What does a young man know? I'm afraid he has never even seen the real Yuan Qinghua."
Luo Zhongbao rolled his eyes and dismissed it,
"Dean Wei, Professor Xiao is right."
Suddenly, an old voice sounded.
Several people turned around and saw that it was the old professor Shang Chuliang.
At some point, he also followed and kept standing behind to observe.
"Old professor, do you also think this is a synthetic product?"
Wei Qingshu asked hurriedly.
Shang Chuliang nodded with a smile and picked up a fragment.
"This kind of synthetic technology was most developed during the Republic of China."
"Due to the war, many Yuan blue and white flowers were destroyed."
"The remaining ones that are not seriously damaged will be reused for supplementary production..."
He talked a lot in one breath, including the production process and history of Yuan blue and white flowers, and explained every material used in detail.
Everyone was stunned and nodded frequently.
Shang Chuliang speaks with authority. He said that this Yuan blue and white is a synthetic product, so it is absolutely correct.
"Old professor, are you deliberately favoring him?"
"My family spent millions to acquire this. How could it be a synthetic defective product?"
Luo Zhongbao was not convinced by Qi Dao.
Shang Chuliang smiled: "If you doubt what I said, I can send these two fragments to the University of Hong Kong and use thermoluminescence to see."
"But the appraisal fee is extremely expensive. If the appraisal is false, you will bear the cost yourself."
The most recognized identification method in the industry is thermoluminescence scanning.
But there are only two institutions in the world that can do this, one is the University of Oxford and the other is the University of Hong Kong.
Luo Zhongbao's face was livid, and he finally smiled awkwardly.
"Forget it, I won't argue with you anymore."
"Anyway, I donated it. If it is broken, it will be a loss to the school and has nothing to do with me."
Just as get out of class ended at this time, he glared at Xiao Feng fiercely, turned around and walked out of the lecture theater. This farce was finally over.
"Haha... Professor Xiao, I really saw you right."
"You will definitely surpass me in the future and become the number one person in appraising antiques."
Shang Chuliang patted his hand and nodded heavily.
Wei Qingshu's face was full of shame. This young man in his twenties was hiding something secretly.
I thought he didn't understand anything, but it turned out that he was an expert in appraisal, and he was slapped in the face.
"Haha...Old professor, I don't want to be the first person."
Xiao Feng smiled awkwardly.
He has no interest in archeology at all, this is just trying to catch up.
