"Brother Niu, Brother Niu, this is the real thing, it's really !! hahaha, I also picked up the leak!" Da Zhuang shouted excitedly, his voice was so loud that he wanted to lift the roof.

I felt a little deafening, and hurriedly stopped him, "Don't shout, don't shout, my ears can't stand it." ”

"It's true. The bald young man was also dumbfounded, as he had said before, he had never detected a real bronze.

To be honest, I was also incredulous about the results, and I always felt that something was wrong, but I was speechless in the face of the results of the scientific instrument test.

"Bald donkey, hurry up, give me the certificate. Da Zhuang kept urging the bald youth.

"Can you speak politely, either swearing, or a bald donkey. The bald man said dissatisfied.

"Who knows who you are? Da Zhuang was in a very good mood at this time, and he didn't say evil words to each other because of the confrontation of the bald youth, and he added his fists and feet.

"My name is Jin Guotao, and I am a researcher at the Zhen Group. The bald young man introduced himself.

As soon as I heard about the Zhen Group, I was angry, "Who cares what your name is, is the Zhen Group amazing?" I disdained him, or the Zhen Group.

"Niu, should I call you Mr. Niu?" asked Xiaoya timidly.

I didn't answer, my face was expressionless.

"Mr. Niu, you may not know something. Zhen's Group is a well-known comprehensive collection of various cultural relics identification, exchange and auction in China..."Xiaoya continued to introduce, but I stopped drinking.

"Aren't there any artifacts made?" I said, sarcastically.

"You joked, cultural relics are relics and relics with historical, artistic and scientific value left by human beings in social activities. It has two basic characteristics, the first is that it must be created by human beings or related to human activities, and the second is that it must be a thing of the past that has become historical and cannot be recreated. In other words, cultural relics must have a historical precipitation. Therefore, cultural relics cannot be made in modern times. Xiaoya explained seriously.

I think it's so angry and funny, is this girl too innocent, or is she pretending to be too good? Or does he really not know the ugly face of the Zhen Group?

"I don't care what your group is, I just want to know when I can get a certificate. "Da Zhuang's money addiction is committed again, and the ghost is obsessed with thinking about the certificate.

"Mr. Wang, that, don't worry. Jin Guotao was unexpectedly humble.

This made us really stunned, since we first met, it was sabre-rattling, there was no friendship at all, and now there must be some scheme. If Xiaoya doesn't really understand the Zhen Group, I may still believe it, and this Jin Guotao, a researcher of the Zhen Group, if he doesn't know the inside story of their production of fake antiques, I won't believe it. I couldn't help but raise my vigilance.

"What's the matter?" Da Zhuang has been in the society for a few years, and he still understands this truth, although he is not so polite, but his tone is still somewhat relaxed.

"Because your bronze is very rare, we would like to provide you with a full set of identification free of charge, including the dating just done, as well as the later determination of the content of the elements, and issue you an authoritative identification certificate and identification report. Jin Guotao rubbed his hands together and said flatteringly, and a discerning person could see at a glance that he had bad intentions.

"It's free, how can there be a free lunch in the world, what do you want?" Although Da Zhuang is not a human spirit, he can still see the twists and turns here.

"We wanted to do a detailed study, so it might take a long time. Look..."Jin Guotao said, the implication of his words was already very obvious.

"That's not going to work, what if you lose or break my treasure?" Da Zhuang assertedly refused.

"You don't have to worry about that, if you have the time, you can be involved in the whole process. Jin Guotao said.

I couldn't help frowning, I had the same idea as Da Zhuang, and we both thought that he wanted to take advantage of our absence, using a means of stealing beams and changing pillars, but this is the same test, so what is he trying to do? Don't tell me, in order to learn knowledge.

"You see, if we can, we can start testing now. Jin Guotao saw that we were hesitant and continued to express his position.

Da Zhuang looked at me hesitantly, and I couldn't see the problem for a while, so I nodded in agreement and waited to see what happened.

A set of familiar operations, smooth and smooth, it can be seen that Jin Guotao is very proficient in the use of equipment.

For half an hour, a few of us didn't have a conversation without words. Xiaoya stared at the machine, Jin Guotao stared at Xiaoya, and Da Zhuang and I both stared at Jin Guotao.

Eventually, the machine stopped. Xiao Ya hurriedly looked at the test report, "Lead, tin, copper, what is, what is this?" Xiao Ya read in surprise.

Jin Guotao said, "I'll take a look," and then leaned over to Xiaoya's side, "Cu2(OH)2CO3, which is a copper-bearing carbonate mineral," and then thought.

I did understand a little, although I still don't understand why the fan line and the gasket, but from the dating and chemical element detection, it is also more inclined to the big and strong bronze is a genuine product.

Da Zhuang looked at their appearance, thinking that there was a problem with the detection, and hurriedly pointed at Jin Guotao and asked anxiously, "Say, you should talk about it." ”

Jin Guotao and Xiao Ya looked at each other, and finally spoke: "This, we found a carbonate mineral containing copper, but I have never encountered a real bronze before, so there is no way to compare." ”

"Is that true or false!" Da Zhuang didn't care about any minerals at all, just wanted to know the answer.

I coughed lightly and said, "Da Zhuang, don't worry. They're researchers, and they'll only rely on instruments to detect them, and if they can detect them together, what do they know about the rest?"

I felt very funny to see Jin Guotao's helplessness, and of course I didn't mind making him pay for his previous arrogance.

Jin Guotao was a little angry when he heard this, but he still dared to be angry and didn't dare to speak, after all, we are not really friendly. "You know, you say!"

I sneered and said, "As we all know, bronze ware is made by people smelting and oxidizing raw materials such as lead, tin, copper and other ores, and then refining the aggregates formed by them to extract lead, tin, and copper with high purity, and then casting them together in a certain proportion according to needs. In the complex environment that it undergoes after its formation, various metals are re-oxidized to form salts similar to copper ore. In this sense, this process of change is a process of reincarnation. When the humidity is high and the temperature is high, the chemical reaction on the surface of the copper is relatively violent, and the metal oxides generated are relatively more, and this period is the growth period of the patina. On the contrary, when dry and cold, the production rate of patina slows down or even stops, and the metal oxides produced are also reduced, which is called the dormancy period of patina. The growth period and the dormant period are not, but they are constantly alternating. When the growth period arrives, new chemical reactions occur in the pores of the previous product and patina, and the porosity of the patina becomes less and less, and there are frequent reactions between the rusts. ”

I paused, enjoying their expressions of relish and fascination, and Xiaoya didn't know where to find the banknotes, quickly recording them. I was very satisfied, and continued: "Specifically, patina is mostly composed of various salts of copper formed by complex chemical reactions between the metal components of bronze, such as copper, tin, lead, and other elements in the surrounding environment, and the color is mostly green and blue..."
