Chapter 306 Professional appraisal

"Old Wang, I'm very curious. How do you do the tests here?" Jia Sidao glanced at the middle-aged man next to him and said, "Especially, the tests for jadeite must be analyzed very accurately?"

For jade, its texture and water head are of course very important, but the carving craftsmanship and artistic conception of the work are also important. After the trip to Yunnan and Jieyang, Jia Sidao had a deeper understanding of the carving of jade works, not to mention that Jia Sidao is still learning the skills of carving.

So, after coming to the jewelry and jade testing center, what you want to know is undoubtedly starting from the jadeite group that Jia Sidao is most familiar with!

Facing Jia Sidao's inquiry, Lao Wang did not show any surprise on his face. On the contrary, he showed a lot of energy. He helped his glasses and said, "This is natural... The testing method we need to do is naturally very different from the methods of identifying jewelry on the market. Especially in jade and nephrite, in jade stores on the market, most of them can determine whether the thing is genuine based on experience and simple instruments. In our testing center, in addition to the simple judgment like in jade stores, each piece of jade used for testing needs to be detected and all the parameters are detected. At this point, I think you should understand it!"

"Well, I can understand this." Jia Sidao nodded after hearing this. Otherwise, what's the use of so many precision instruments in the testing center? If there is no one instrument used during testing, I'm afraid these precision instruments are just decorations. Moreover, by testing the instrument, comparing the parameters of the jade brought by customers with the real jade, it is clear at a glance whether it is true or false, and it is even more convincing.

"However, except for jade, do other jewelry, jade and other things follow this process?" Jia Sidao asked.

"It's almost the same. Basically, the general process here is like this. First of all, we need to register and number all the things sent, and take photos and file them one by one, so as not to be confused at that time, or just be thrown away by someone. Such a thing happens not only shows that there are loopholes in our management, but also an irresponsible act for customers!" Speaking of this, Lao Wang also looked at Jia Sidao, and when he saw Jia Sidao's expression, the smile on his face became more kind.

The circle of jewelry and jade identification is very small, and not many people know about it. Moreover, it is like the "Jewelry and Jade Inspection Center" in the provincial capital. In terms of the province, such similar institutions are really a handful of. Once any fraud or theft or fraud occurs, they will soon be promoted in the circle.

Then in this circle, he will become the point where everyone shouts and beats the rats across the street.

This is not like the nature of the wrong identification due to some negligence during the inspection process. If it is just an error in the identification, it will not have much impact on other people in the circle. For example, some famous artists cannot be determined 100% when identifying an antique. However, these famous artists, considering their reputation, will not only not admit their mistakes, but will also stick to their initial identification results.

Anyway, most of the antiques industry follow the crowd and are very chaotic. Most collectors who are a little more knowledgeable will not recognize their words in their hearts just because of the identification of an expert! Generally, they will retain some of their views on the antiques in their hands!

Jia Sidao has really entered the antique industry, and he naturally knows these small paths! Not to mention the "experts" in the antique market, the antiques identified by experts in some programs broadcast on TV stations, not to mention the authenticity of those antiques identified by experts. Just the value estimated by experts is a lot of moisture!

Jia Sidao could not control these things, and he had no connection with the so-called experts, so he naturally treated them with the attitude of "entertainment".

"After registering the jewelry and jade, the next step is to weigh it to determine the specific gravity of these jewelry." Lao Wang said with a smile, "Many fakes can show their true shapes at this step. You must know that different substances have different densities. Just say jade. Although most jades are very bright and are also treasures, we have received a lot of jade jewelry shaped by gums. Then, we can also use the naked eye to observe, or use the magnifying glass or microscope to further determine the authenticity of the jewelry identified. In this regard, there is color, whether it is dyed or not. Then, we use various precision instruments to conduct a parameter test...."

As he was talking, Jia Sidao and Lao Wang had already walked to the door of a laboratory together.

Jia Sidao turned his head and looked at Lao Wang. Lao Wang also walked to the door as Jia Sidao wished, looked inside from the glass window installed on the door, and then knocked on the door. When someone inside opened the door, Jia Sidao followed Lao Wang and entered the laboratory together!

While walking, Lao Wang also explained: "Xiao Jia, there are many professional instruments in our testing center. Come on, let's take a look in this laboratory first."

Jia Sidao looked around and saw several staff members in the laboratory who were detecting something. Because of distance and because of the obstruction of the staff's hands, Jia Sidao could not see clearly. However, just the instruments in the laboratory, wherever they came into view were gem refractometers, gem microscopes, gem polarizers, gem spectrometers, infrared spectrometers, etc., all kinds of things that Jia Sidao had only seen on the Piaotianyi network before.

It really made Jia Sidao want to have a few more pairs of eyes!

Perhaps seeing Jia Sidao's curious eyes, before taking a few steps, Lao Wang pulled Jia Sidao to the side of a staff member, pointed to the instruments that the other party was detecting a ruby, and said: "The laboratory is equipped with advanced instruments such as infrared spectrometers, gem microscopes, spectrometers, etc., through which they can observe the waveform diagram of the gem, the color and other data after spectroscopy, and then conduct a general analysis. By comparing the basic parameters of the gems in the computer, you can draw a relatively accurate conclusion."

"Then the one in front of you..." Jia Sidao looked at the instrument and asked with a little hesitation, "It should be an infrared spectrometer, right?"

"Yes!" Lao Wang replied proudly, "The price of this instrument is relatively expensive among the many instruments in the testing center. It costs hundreds of thousands of yuan in the testing center. And its function, based on your understanding, I think it is very clear."

Lao Wang knew very well that judging from the conversation just now and Jia Sidao's current performance, Jia Sidao is not a young man who knows nothing, especially in jade, who is more likely to be an expert. Therefore, when talking to Jia Sidao now, he is not as clear as he did at the beginning, and he explained it very clearly.

Jia Sidao didn't care about this either.

The infrared spectrometer in front of you can quickly and accurately detect the characteristics of some jewelry and jade based on the characteristics of the infrared absorption spectrum of jewelry and jade through the emergence of strong absorption peaks. For example, those jades that have been bleached and filled will have nowhere to hide under such instruments.

Although, in Jia Sidao's view, such detection ability is somewhat similar to his ability, it is just a guaranteed detection, and it does not have such ability perception, which is more delicate and emotional. However, even so, not every detection center can be equipped with such equipment.

Now, after the initial surprise of seeing these precision instruments, Jia Sidao recovered and his eyes became much calmer. Lao Wang also took this opportunity to introduce Jia Sidao to more operation methods and their specific uses. Jia Sidao was very satisfied with Director Chen's arrangement.

Isn’t Lao Wang’s role and his talkative attitude just a most qualified tour guide to the “jewelry and jade testing center”?

Of course, after visiting several laboratories, Jia Sidao naturally appreciated the style of many staff members in the testing center when testing jewelry. His concentration made Jia Sidao feel a little reluctant to disturb their work.

"By the way, Lao Wang, I think today is a weekend off day. Why, there are a lot of staff in the testing center." Jia Sidao said, "When you usually do, wouldn't you say that more testers here will be there?"

"This will naturally be a little more." Lao Wang thought about it and said, "But the work of this testing center actually depends on the season. For example, holidays, or something good, and many people are preparing to get married. Then, for a while ago, in contrast, places like our testing center will be much more busy. And under normal circumstances, our testing center, about 20 or 30, can still be busy."

"Haha, that's great. I just visited it now and felt a little tired. Especially when analyzing the instruments and data, it takes a lot of energy." Jia Sidao said, "If you are still very busy at work, it will be too tiring."

"That's not true." Lao Wang replied, "The most important thing for our work is to rest. We must pay attention to our eyes, body and other health issues. Otherwise, when we are busy, each of us will have four or five hundred pieces of jewelry and jade that we need to test every day."

"So many?" Jia Sidao was a little surprised. If these twenty or thirty people were four or five hundred pieces each, wouldn't it mean that in a day, the entire testing center needed to test nearly 10,000 pieces of jewelry?

"It's not because there are too few such testing centers, and the profits of counterfeiting on jewelry and jade on the market are too high?" Lao Wang spread his hands and said, "Our customers are not only popular consumers, but also many merchants! In general, the number of jewelry appraisals sent by merchants and consumers is about 64. The difference is that almost all the goods sent by merchants are genuine, while those sent by consumers are just the opposite. Most of them are fakes."

At the end, Lao Wang was obviously helpless and sighed. Everyone knew the truth about it! Fortunately, Lao Wang had been working in the testing center for a long time and had witnessed such a thing for many years. There was nothing to sigh about, and he quickly regained his expression.

"So, our colleagues in the entire testing center have to pass on every piece of jewelry sent for testing. Only after the system summarizes the parameters and indicators of the jewelry can the final result be determined and the appraisal certificate is issued." Lao Wang said, "It can be considered as, helping those consumers check."

"However, as far as the current jewelry and jade market is concerned, it is far from enough for your testing center to do so." Jia Sidao said. When he walked out of a laboratory, he suddenly saw a promotional window in the corridor with some simple methods for identifying jewelry and jade, and many illustrations to illustrate, just like the wall stickers in kindergartens, it is very vivid and vivid.

"Haha, these are all our colleagues who are free to play." Lao Wang said with a smile, "It can be regarded as doing some effort to purify the market. Sometimes, we will make some time and choose to go to some squares to do a free appraisal for everyone..."

Jia Sidao remained silent. Although Lao Wang's last words made the image of the entire testing center taller. Even if he held such an event, most of the time, there were sponsorships from other jewelry stores. No matter how bad it was, there were potential factors to improve the image of the testing center.

But it is undeniable that such an event is indeed beneficial to consumers. Just as Jia Sidao participated in the folk antique treasure appraisal activities organized by Ji Yanran and others, I am afraid that the same is true? As for why Ji Yanran came to the "Jewelry and Jade Inspection Center" to invite appraisal experts in this field, Jia Sidao felt at this moment.

"By the way, Lao Wang, I have been visiting for so long, and I can't help but feel itchy. Look, are you asking me to participate in the testing process as well?" Jia Sidao raised his hand and looked at the time. It was still early. Ji Yanran did not send anyone to call him. If he continued to wander like this, it would not be of much significance to Jia Sidao. Anyway, in the past time, Jia Sidao had traveled almost every laboratory. Suddenly, he saw a new customer coming in at the entrance of the hall. Jia Sidao felt a move and had the intention to try these instruments with his own hands.

However, as soon as he said that he felt a little hesitant on Lao Wang's face, Jia Sidao understood in his heart that the other party might be worried that Jia Sidao's incorrect operation would damage the instrument.

"Otherwise, when I was testing, Lao Wang, you stand by me and help me check it?" Jia Sidao said hesitantly, "In this way, you don't have to worry about any major problems." As for the plan to apply directly to Director Chen, Jia Sidao definitely wouldn't raise it now.

Although, as long as Jia Sidao spoke and Ji Yanran’s relationship was on the other side, Director Chen would agree. However, this would be a big offense for Lao Wang. If Lao Wang could agree first, Jia Sidao would not make a fuss about his relationship with this testing center if he wanted to take the test on his own!

Sure enough, just after Jia Sidao's suggestion was expressed, Lao Wang's face, which was a little hesitant, quickly calmed down and said, "Okay, I see, let's find a jade jewelry that Xiao Jia is familiar with to test it. How about it?"

"Okay." Jia Sidao was naturally happy to do so. If you detect other things, such as diamonds, and not familiar with them, it would not have much practical significance for Jia Sidao. However, if you detect jade jewelry at this time, it would make Jia Sidao more confident at tomorrow's folk treasure appraisal conference!

Regarding how to identify jade jewelry in the professional "Jewelry and Jade Inspection Center", Jia Sidao had just learned about the program from Lao Wang, but this was ultimately because he understood the program, not? Specifically, what would happen under the inspection of precision instruments is not something Jia Sidao could understand by imagining it out of thin air.

Immediately, Lao Wang led Jia Sidao into one of the laboratories, where there was already a young staff member, and in front of him, there were a lot of jade jewelry. Such jade bracelets, jade Guanyin pendants, jade ring faces, etc., everything was included!
