Everyone present was stunned. After looking at each other, they nodded heavily towards Qin Fen.
"Qin Fen, do you really think that everyone doesn't understand anything?! The people present are all experts who have been in the antique industry for more than ten or even decades!"
Peng Wanli said disdainfully.
"Haha, since you know it, everyone must also know that this kind of thing appeared in the last century, especially in foreign countries!"
"Yes, this devitrified glass is called Imoli gem abroad, which is quasi-jade. It is one of the most imitated jadeite products." He Wanfeng nodded at this time.
"Haha, Vice President He is right, and this thing is originally a piece of devitrified glass, worthless!"
While speaking, Qin Fen slowly picked up the elder's 'Glass Seed' Guanyin and gestured towards everyone.
"This is impossible!"
When Mr. Zhang heard this, he immediately retorted, his face turned red.
"Haha, Mr. Zhang, please be patient. The density of this devitrified glass is smaller than that of jade, so when comparing the weight of the same size, this thing appears to be slightly lighter. Everyone has compared it just now. How do you feel?!"
Qin Fen chuckled and looked at everyone again.
At this time, some people who didn't pay much attention hurriedly took two pieces of glass of similar size in their hands again and weighed them. Sure enough, their weights were different.
"Mr. Zhang is indeed a little lighter!"
Someone already nodded and said.
"Humph, Qin Fen, what kind of identification method do you have? Even if there are two pieces of jade of the same size, as long as they have different colors and densities, then of course their weights will be different."
Peng Wanli's face turned cold and he said coldly.
"Haha, President Peng, I will shut you up later! Then find a place to cry!"
"Huh, you...then I'll wait and see!"
Peng Wanli was speechless and stamped his feet angrily.
"Tong Lao, do you know if this is jade?! Is there any other identification method?!"
At this time, Qin Fen suddenly moved his eyes to Tong Guyun.
I saw Tong Guyun's face was calm and calm, and it was obvious that he had already had an idea in mind.
Although Tong Guyun is a master of porcelain, he has been honing his skills in identifying jade during this period, so he just took advantage of this opportunity to give Tong Lao a chance to show off.
In this Antiques Association, Mr. Tong's previous performance was indeed unsatisfactory. Now, it is a good opportunity to slap these people in the face. Of course, Qin Fen must satisfy him.
"Haha, I have little talent and knowledge, and I don't dare to show off in front of President Qin. However, I do know a method that may be able to identify one or two."
Tong Guyun knew Qin Fen's intention, and nodded gratefully towards Qin Fen, then stepped forward and said lightly.
"Old boy, I didn't expect you to stop playing with porcelain and start playing with jade?!"
"Yes, it seems that Mr. Tong has blossomed in many aspects."
Some people who usually looked down on Tong Guyun have begun to ridicule him in a different way.
"Haha, I, Tong Guyun, have been learning all my life, and I never dare to claim to be an expert. There are some people who know a little bit about it, but insist on pretending to be an expert!"
Tong Guyun smiled heartily and said lightly.
"Humph, Tong Guyun, please tell me your method quickly. Where did all this nonsense come from!"
Peng Wanli's face changed, he didn't expect that Tong Guyun would now have the same virtue as Qin Fen!
"President Peng, please don't be anxious. This way you can sit in your seat longer."
Tong Guyun's face changed slightly, and she replied coldly to Peng Wanli. Peng Wanli was so angry that he was speechless again.
Qin Fen showed a proud smile on the side.
This old boy doesn't even use a single curse word when he hurts others.
"Everyone, my method is actually very simple, just use water!"
Tong Guyun calmed down and said angrily.
"water?!"
Everyone was stunned.
"I know, Mr. Tong is planning to test the hydrophobicity of these two pieces of jade, right?!"
A member who studied jade suddenly realized something.
"Haha, yes, it is hydrophobic!" Tong Guyun chuckled: "The hydrophobicity of glass and natural jade is very different. As we all know, glass is very hydrophobic. As long as water drops fall on it, it will disperse quickly, but
Natural jadeite is just the opposite. When water drops on it, it will gather for a long time and will not spread out!"
"There is water in my glass!"
At this time, a member had already picked up the water glass he had placed on the conference table and handed it to Tong Guyun.
"Tong Lao, let's start!"
Qin Fen nodded and gestured towards Tong Guyun.
Tong Guyun responded with a smile, her eyes fell on the two glass jadeite on the table, and then she carefully dropped a drop of water on the glass jadeite she was wearing.
"Bata..."
Water drops fell on the jadeite, and as expected, the flowers did not bloom instantly. Moreover, the small water droplets splashing on the side slowly gathered towards the big water droplets, and finally merged into one.
Everyone held their breath and stared at the childlike jade Guanyin carefully. After about a minute, the water droplets showed no sign of spreading.
"Sure enough, it didn't scatter. It seems that Tong Lao's glass jade has very low hydrophobicity, so it should be natural jade."
"It shouldn't be wrong, and the quality is much better than Mr. Zhang's."
At this time, some people had already started whispering to each other, and it was obvious that these people couldn't put it down when they saw Tong Guyun's piece of natural glass jadeite.
Tong Guyun ignored these and poured a drop of water on Mr. Zhang's jade.
"Ah... look, they're scattered."
"It really fell apart."
"It's over. There may be a dispute over the authenticity of Mr. Zhang's jadeite!"
A shocking scene finally happened. The water dropped on Mr. Zhang's jade and spread out in all directions in an instant.
At this time, Mr. Zhang's face turned green. He stared closely at his glass Guanyin and kept muttering to himself, this is impossible, this is impossible...
Compared to everyone else, Peng Wanli also had a flash of shock on his face. As the president of the Cultural Heritage Association, he was certainly not a person who didn't know anything. Normally, he would have firmly believed that this jadeite was glass.
of high imitations.
But it was different now. He was competing in a bet with Qin Fen. How could he admit defeat so easily? Therefore, despite being shocked, his face was still full of disdain.
"This is the simplest method. It can't prove anything at all!" Peng Wanli simply said bravely.
"Ha, President Peng, it seems that you won't shed tears until you see the coffin. Well, I will make sure you die today!"
At this time, Qin Fen had a smile on his face, and as soon as he finished speaking, he looked directly at the crowd.
"Actually, those of you who have some common sense should already understand what the outcome is now. However, there is someone here who is still unconvinced, so I have no choice but to make him give up completely."
After Qin Fen finished speaking, he picked up Tong Guyun's glass jade and scratched it hard on Mr. Zhang's jade!
"ah……"
"President Qin, this is..."
"Do not talk!!"
Qin Fen ignored everyone's comments and repeated his old trick. Instead, he picked up Mr. Zhang's 'glass' jade and scratched hard on Mr. Tong's jade.
Then he placed the two Guanyin coins on the table again, raised his head and glanced at everyone. At this time, apart from the shock on some people's faces, most of them were just confused, wondering why Qin Fen did this?!
"Everyone, there is a common sense. I think everyone should know it, including President Peng. He knows very well that the hardness of glass-imitation jade is lower than that of natural jade. Therefore, if the two are scratched against each other, there will be traces of traces on the glass.
There are heavy scratches, but natural jadeite has no or very light scratches, and can even be wiped off."
After Qin Fen finished speaking, many people nodded, even Peng Wanli didn't comment.
"One more thing, look at the green fluff inside. It does look like green color, which adds a lot of decoration to the jadeite, but it is just an artificial method. It uses green pigment to process the interior of the glass at high temperatures.
, the bubbles left behind are covered up. So, you can see for yourself whether it is true or false!"
After Qin Fen finished speaking, he clapped his hands and turned his face to one side.
Likewise, this time it was Peng Wanli who rushed up first, picked up two jadeite pieces and compared them, his face suddenly became extremely ugly.
At this time, some sharp-eyed people had already seen the clues.
"Look, there is a heavy scratch on Mr. Zhang's jade, but there is no scratch on Mr. Tong's jade!"
"Master!"
"Mr. Zhang, I'm afraid you have been deceived."
By this time, the sound of discussion had already filled the huge conference room.
I saw Mr. Zhang slowly taking his 'glass type' jade from Peng Wanli's hand, and muttering to himself without tears: "I have been appraising treasures for decades, but I didn't expect that the thing I have been wearing for six years is actually a piece of jade."
Glass, what qualifications do I have to stay in the Antiques Association!"
"Snapped!"
As Mr. Zhang spoke, his face changed, and he waved his hand and threw the 'Glass Seed' to the ground. It immediately broke into pieces. If it was difficult to judge at first, but at this moment, everyone could see clearly that this pile on the ground,
It's clearly broken glass.
“It’s really a high imitation of glass!”
No matter when, where, or who you are, there is always no shortage of people eating melons. At this time, some people were already watching the excitement and shouted out without fear of trouble.
Mr. Zhang was simply ashamed. After the fall, he strode outside.
Seeing this, Qin Fen winked at He Wanfeng. He Wanfeng understood and hurriedly chased after him. He grabbed the other person and persuaded him: "Mr. Zhang, please calm down. President Qin is right. In our industry,
, how can you be careless? You can’t give up on yourself just because of this failure.”
"But... I really don't have the shame to stay in the association. It's too embarrassing." Mr. Zhang said with shame on his face and continued to walk out.
"Mr. Zhang, it's inevitable for people to make mistakes. When working in the antique industry, it's common to get caught in the eye. It has nothing to do with your ability, and it has nothing to do with your status, age, etc. So, it's nothing, just treat it as tuition.
Now, my knowledge has also increased, hasn’t it?!”
Seeing this, a smile appeared on Qin Fen's face. It seemed that these people all had a sense of arrogance, but some people would be too arrogant, which would be serious arrogance, such as Peng Wanli.
As soon as these words came out, everyone present felt ashamed. Those who originally wanted to see Mr. Zhang having fun all lowered their heads.
Mr. Zhang was startled immediately, turned around, and said to Qin Fen with a look of shame on his face: "President Qin, you are right. I criticized you a lot before, but now it seems that you are the real one."
