There was a commotion in the crowd.

But Big Scar is not stupid, and after listening to what I said, he sneered and said, "Based on this, how dare you prove that it is fake?" ”

"This bronze mirror is a family heirloom, and the devil knows whether its origin is true or false!"

"What if my ancestor accidentally dyed it with mercury?"

"You're an archaeology student, that's all you can do?"

The crowd looked at me again.

This reason is indeed not convincing enough.

But I still said calmly: "Of course, what I just said is just to point out the mistakes you have exposed in your language. ”

"Whether it's lead or silver, it's really not enough to be proof."

"Next, what I'm going to say is the key."

Big Scar was stunned.

"To identify the bronze mirror, you can distinguish the real from the fake from four aspects: listening to the sound, seeing the shape, distinguishing the rust, and smelling the smell."

"To listen is to knock on the bronze mirror, and to distinguish by the sound made by the bronze mirror."

"Because the new and old copper mirrors are made in different proportions of copper, tin, lead and other raw materials, the sound emitted is also different."

"The old bronze mirror generally has a low and mellow voice. The sound of the new imitation copper mirror is relatively crisp, even harsh. ”

I picked up the bronze mirror, bent my fingers, and tapped it on its surface.

Bite.

The sound, it's crisp.

The crowd was in an uproar.

"Oh, really."

"This sound is comparable to my high school alarm bell."

"It's not buddy, you really know how to appreciate treasures?"

"This young man, what he said is reasonable and credible!"

Big Scar's eyes narrowed, his face already wrinkled.

The stall owner waited intently for me to continue.

Without a pause, I continued: "In addition to the recognition of sound, it is to look at the shape and find the difference from the shape. ”

"In order to ensure that the copper mirror can have a real and clear effect, the ancients cast the copper mirror, and the size of the mirror and the arc have a strict proportional relationship."

"Smaller copper mirrors can see a relatively gentle arc, and copper mirrors of more than 20 centimeters are basically a plane, and there are no obvious arc fluctuations."

"The curvature of the new imitation copper mirror is generally disproportionate to the size of the mirror, the arc of the large copper mirror is very large, and the arc of the small copper mirror shrinks unnaturally."

"Therefore, the people and scenery reflected in the imitation copper mirror are often not clear and even deformed."

I turned the bronze mirror over and aimed it at Chen Meng.

She immediately understood, looked at herself crookedly in the mirror, and couldn't help but cover her face and say in surprise: "Mom, you look so ugly, hell!" ”

Everyone laughed.

I took back the bronze mirror and said lightly: "Your mirror, the arc is too weird, in ancient times, if you present this thing to Cixi, you will have to lose your head the next day." ”

Big Scar twitched and was silent.

"The third is to distinguish rust."

"In terms of rust, the rust of the new imitation copper mirror is made by chemical reaction, or the rust on some old bronze objects is scratched off and glued to it."

"The method of identification is also very simple, if the imitation copper mirror is placed in water, there will be an obvious feature, that is, it does not stick to water."

"The rusty areas do not get wet, just like the water droplets on the lotus leaves, they can't melt in."

"Besides, there's the fourth point."

"Smell it!"

"After the imitation copper mirror is watered, it will emit several flavors, one is the smell of sulfuric acid, one is the smell of alkali, and the other is the smell of copper."

"And the old bronze mirror generally only has a copper fragrance."

Without waiting for everyone to react, I grabbed an unfinished bottle of Cestbon on the ground and was about to pour it on top of the bronze mirror.

The big scar couldn't hold it back, and immediately glared and scolded: "You stop Lao Tzu!" If you break it, you'll lose money! Little bastard! ”

I ignored it and fell upside down.

"You ......"

Big Scar gestured to get his hands dirty.

I raised the bronze mirror in my hand: "You can see that my half bottle of water was poured on it, and it didn't get any touch at all, and there was a copper smell!" ”

"That's not enough to prove a fake?"

The crowd applauded.

"Brother, you deserve to be a top student in the Department of Archaeology!"

"Well-founded and convincing!"

"How can this person sell fakes, isn't this a cheat?"

"Stallholder, you have to thank this classmate!"

"If it weren't for him, you would have given the 500,000 for nothing!"

Many people began to help stall owners.

Big Scar was already pale, and he opened his mouth to refute, but he couldn't find a reason.

The money-walker stall owner, but his face also became gloomy, he had already reacted, and he almost suffered a big loss!

He said coldly: "This brother, you have your own rules for taking money, since you know those doorways, you also know the rules!" ”

"Today's business is not done, I don't care about you, take your things and get out!"

After saying that, he grabbed the bronze mirror in my hand and smashed it on the big scar.

Big Scar's body shook, his chest rose and fell violently, and it seemed that he couldn't help but explode, but there were too many people around, so he still endured it.

But soon, he turned that resentful gaze at me, and looked at me a little madly:

"Boy, you remember!"

"I'll settle this account with you!"

"Usually walk at night, be careful!"

After speaking.

He wiped his chin with his hand.

It's his signature move.

Whenever he wants to vent.

That's what it does.

I can't forget the scene six years ago.

It proves that he has murderous intentions towards me.

My purpose was achieved.

But I still pretended to be not afraid of heaven and earth, and said coldly: "Okay, you have a kind of stabbing Lao Tzu to death now!" ”

"So many people are watching, do you have a seed?"

"Why don't you speak? It can't be a turtle with a shrunken head, right? ”

"If you don't have a seed, get out of here!"

Taunt, pull full.

Sure enough.

When Big Scar heard my words, his whole body trembled, his eyes were even more violent, and the green tendons on his forehead also flare.

A disgusting vicious dog, no matter how much it looks like a poultry, can't be changed!

Instead of making a move, he pointed at me twice, then pushed through the crowd and quickly left.

When he was gone, the crowd applauded.

"Lao Tie, awesome!"

"Dude, what's your name? I also have a baby at home, so I'll have time to identify it! ”

"Sure enough, it's still a great student of Ling University!"

"Tsk, this copper mirror seller is also a bad thing, hahahaha!"

I waved my hand to everyone: "Don't do it, don't do it, it's not too early, it's time to go back to school, let's let everyone go!" ”

I took Chen Meng's hand and was about to turn around and leave.

"Wait, lad."

The stall owner stopped me, picked up a pair of jade bracelets from the bag on the side of the stall, and said to me with a smile: "Come, you can put away these jade bracelets." ”

"Although it is not an expensive object, and it is worth hundreds of yuan on the market, it is also a good jade handed down from my family, so I should thank you two for your help."

"If it weren't for you, if it weren't for you, the 500,000 yuan would have been spent, and my wife would have to chop me up!"
