Liu Yuan was a little speechless at first, and then a little fluttering.

Brother is such a stylish man, no matter where he goes, he can shine and attract attention.

Introducing experience or something, Liu Yuan has no opinion, the profits of the Jinyu family are rich enough, there is no need to do anything with the materials, teach yourself the experience of distinguishing gold and silver, and there is no loss to yourself, plus this is a great opportunity to show your face, how can you not miss it.

When everyone's applause and praise were almost expressed, Liu Daguan stood up a little "embarrassed" and signaled everyone to be quiet, and then said with a smile: "Actually, the head of the meeting is too high-minded, there are so many experts and seniors here, how dare the younger generation say anything to advise, it is difficult to say that it is almost the same." ”

"Brother Liu, just give me some advice, to be honest, I'm a fat man who obeys you, I'm licking my tongue here so numb, you just throw it away, it's fast and accurate, I am dazzled." Zhang Fatzi of Jin Yuzhai on the side said with admiration.

Xu Lao's shopkeeper Xu Ji said convincingly: "Now it is the world of young people, and it is really not good to be old." ”

"Two, let's get together again when we have time~~" Liu Yuan smiled at the two, left his seat, and walked in front of Zheng Dong.

"You please, you please~~" Zhang Fatzi said hurriedly.

Now is not the time to chat, not only some peers, but also Cui Tingshi, Zhao Sima, Mr. Su and others, all of them are looking at Liu Yuan with interest to see what methods he has used to stand out among so many senior peers.

In full view of everyone, Liu Yuan walked to Zheng Dong's location, took the two problematic materials, and carefully observed them.

As soon as the two things were started, Liu Yuan immediately saw that there was no problem with the gold and silver nuggets in terms of color and hardness, the color was natural and harmonious, and the hardness was a little soft

With the second sound of "pop", Liu Yuan threw the two pieces of material on the table, and he already knew it.

"Shopkeeper Liu, I don't know if you like the clues?" Seeing Liu Yuan's confident appearance, Zhang Chengqi's heart moved, and he couldn't help but ask curiously.

Liu Yuan said with a smile: "Although this material has been carefully camouflaged, the fake is fake, and the younger generation is lucky to see it." ”

"Oh, listen up."

Liu Yuan held up one of the yellow gold nuggets and said: "Take this piece as an example, there is no problem with the color, the gold with good color, there is no problem with the hardness, with a light stroke of the hand, there will be scratches on it, which is also the characteristic of good gold, many shopkeepers or customers see this, they feel that there is no problem, in fact, this is wrong, because this is only the surface." ”

"Sheng Meng is here to appreciate the face, the younger generation does not dare to hide private, share some of my experience with you, a complete test, including the color, weight, hardness, listen to the sound of four steps, look at the color and hardness is two of them, but can detect the outer layer of gold, it is difficult to say whether there is a problem inside; The first three methods, many of which are old and respectful, know even deeply, and do not talk about it below, and the fourth to listen to the sound is summarized by the younger generations when they are bored. ”

"When the good gold and silver are thrown on the ground, they make a dull sound like a trumpet, without reverberation or trembling, and vice versa."

"Shopkeeper Liu, you said that listen to the voice, I know for the first time that there is this detection method in the Dao, it is indeed not, but the weight you said, I will also do this, I can't detect the problem with the piece in your hand for anything, and please ask the shopkeeper Liu to give advice." Zheng Dong humbly asked for advice.

Liu Yuan said confidently: "This is very simple, in fact, like the skill of weighing, relying on practice makes perfect, the usual fake silver, fake gold, the most used, is to fill lead, in the gold and silver in the lead, fill more, big, light weight, obviously light and fluttering, there is no sense of heaviness, you can find out a weigh, like this piece of gold in my hand, in fact, it is also filled with lead, but he did it very cleverly, everyone was blinded by it." ”

"The usual lead is poured inside the gold and silver, because the lead is lighter than the gold and silver, no matter how well he does, in his hand, there is always a very slight sense of awkwardness, very simple, either this head is heavy, or that light, or this side is heavy, that side is light, in fact, this is related to the balance point, and this problematic gold nugget in my hand, if I guess well, there is more than one place in it with lead, but in several places with lead to make a sense of balance, and deliberately cast into gold cakes, the amount of water is small, so that That's not easy to figure out, am I right, Zhang Huishou? ”

"Ha Lu Ha, wonderful, wonderful, and then terrifying." Zhang Chengqi didn't say "yes" directly, but this also confirmed what Liu Yuan said.

"Really? I'll see if that's the case. Although Liu Yuan said the truth, but hearing is false, seeing is believing, Zheng Dong asked him to bring a pair of special gold and silver scissors, and cut them in public.

No matter what you say, you can tell the truth as soon as you cut it open.

"Hey, it's revealed, the white one is lead, yes, it's lead, it's lead."

"Yes, yes, there are two places, ah, there is ~~" in the middle~"

"This ~~~~ such a big golden cake is only mixed with a little lead, as for it?"

"No wonder, there are two pieces where I feel that something is not quite right, but I can't find the reason when I look for it, and now it seems that it must be exactly the same as this."

"This chapter is really a good method, so many old connoisseurs have capsized in the gutter."

When Zheng Dong was cutting gold, there was a large circle of heads next to him, they all wanted to see how the material that was difficult for so many experts came out, and now they saw that the gold was cut and the lead flowed out, exactly the same as what Liu Yuan said, and the careful people also counted that the gold nuggets the size of a baby's fist were poured with lead in a total of eight places, probably for the sense of balance that Shopkeeper Liu said.

It's amazing, just shake it like this, throw it again, and you can tell it so quickly?

For a while, the eyes of all the peers looking at Liu Yuan were a little strange, and they became a taste of worship.

It's amazing, how old is he now? The hair has not yet grown, the milk smell has not dried, it is estimated that when the many people present make jewelry and master masters, Liu Yuan is still peeing and playing with mud, and he is still with Yuan Guangtou, who is known for his poor craftsmanship on Jinshui Street, Yuan Guangtou's level is simply not worth mentioning, it is estimated that the craftsmanship of some time-honored gold jewelry apprentices is better than him, God, other people's apprentices, it is very good to be able to learn seven or eight points of the master's craftsmanship, this Liu Yuan, that craftsmanship is dozens of times stronger than his master, hundreds of times.

That's the gap.

Looking at these eyes, Liu Yuan didn't understand what they were thinking, and secretly thought in his heart: If you have a period of experience representing the company to participate in the industry competition of the world, you will not leave the studio for two months, and you will look at and throw and throw the gold every day, and sleep with gold and silver bars in your sleep, and the dream of continuous hair is also related to gold and silver, you will know what kind of feeling it is, and the fraud of gold and silver in later generations will be dispatched to precision machinery, and now the "trap" carefully set by Zhang Chengqi is good. However, compared to the cheating of later generations, it is several grades worse.

It's easy to tell, and naturally it's not a problem.

"Okay, good, it's really young and promising." Zhang Chengqi said with a smile: "I suggest that you once again give our applause to our shopkeeper Liu, and thank him for sharing his experience with us." ”

For a while, the applause at the scene was thunderous, not only those peers, but also the onlookers.

Those who have the ability can naturally afford it.

When the applause stopped, Zhang Chengqi stood up and said with a righteous face: "I guess you are all very strange, how can you set up such a fake and real material for a good exchange?" The reason is very simple, I recently received news that there are some gold and silver jewelry similar to this material on the market, using the same method, a small amount of adulteration in gold and silver, pit customers, these people, is simply the black sheep in our jewelry guild. ”

"If there is such a person in the guild, the head of the guild will not tolerate it, resolutely expel the guild, and then hand it over to the government for severe punishment."

Zhang Chengqi's words were righteous and categorical, which made the shopkeepers in Yangzhou silent, and no one dared to refute it.

It's just that Liu Yuan was a little puzzled in his heart: This is true, but for what, why did he seem to smell a smell of conspiracy
