Chapter 853 Du Yile Was Deceived Too

After hearing the ins and outs of the incident, everyone felt that this matter was tricky. Otherwise, if the bottle was genuine, even if the booth was a bit remote, there were so many people in the ghost market, and it was coming to the end of the ghost market. It's impossible for no one to see it, right?
Therefore, both Yuan Hongjian and Du Yile felt that this jade pot and spring vase should have a relatively large flaw, so they saved it until the moment when Zhuang Shengjing discovered it.Besides, a total of less than 2 yuan, is it just to deceive Zhuang Shengjing?How much hatred would there be to set up a bureau just for Zhuang Shengjing?

Of course, even if there is something wrong with this jade pot spring bottle, it cannot be concluded without evidence. Therefore, everyone looked at Chu Chen, who had already been identified, and wanted to hear his answer.

Chu Chen said with a chuckle: "This jade pot spring bottle is indeed very good in terms of performance, but I don't know if the maker is superfluous or what, but he actually made flint red at the bottom of the bottle. A fatal flaw has been opened."

Hearing this, Zhuang Shengjing had a different opinion and said, "Mr. Chu, if I remember correctly, there is flint red because there is flint red in the fetal soil. If the fetal soil is finely refined, then there are very few flint red. For example, in the third Qing Dynasty, the smelting of fetal soil was used to smelt fine small utensils, etc. But the porcelain firing technology of Xianfeng Dynasty was weak, and the smelting of fetal soil was not as good as that of the third generation of Qing Dynasty, so it is normal to have flint red?"

"You're right!" Chu Chen nodded.

Generally speaking, fine porcelain stones and soil ores are often highly weathered and contain trace amounts of iron. Ancient craftsmen used the old-fashioned iron removal method to dilute the porcelain clay, filter it with a net, and put a few original magnets in front of the net. , cannot absorb trace iron cleanly.

Porcelain bodies made of this kind of porcelain clay need to be aired for a long time after being glazed, so that the moisture in the body and glaze juice can evaporate.Next, with dry pad cakes, slag, and saggers, put them into a dry kiln to produce porcelain as white as jade, and the flint red phenomenon will not occur on the astringent body.This is the real reason why there is no flint red phenomenon on most ancient porcelain astringent tires.

On the contrary, when the blank glaze is not completely dry, the iron molecules in the blank will undergo physical and chemical reactions under specific conditions at a specific high temperature in the kiln, so the iron molecules will become iron oxide and firmly adhere to the glaze. On the astringent tire.This is the flint red phenomenon.

"Mr. Zhuang, what you said is indeed possible, but this is under the condition that flint red is formed naturally, but what about your jade pot and spring bottle..."

Speaking of this, Chu Chen hung up the bottom of the bottle to dry: "Flint red looks unnatural, and there are dots of black matter, if you look carefully, you will know that these black spots are actually iron slag. "

"Iron slag?!" Hearing what Chu Chen said, the three of them were quite surprised. They hurriedly stepped forward to take a closer look, and found that it was really iron slag, especially with the help of a magnifying glass, it was even more obvious at a glance.

In fact, Chu Chen had heard about the method of making Flint Red for a long time. At that time, Uncle Wu told Chu Chen that when he went to the porcelain capital in the 80s, he saw someone using slag and iron powder from an iron factory to adhere to On the bottom foot, he asked the man why he did this, and the man told him that he was making flint red.

However, with this method, although there is still flint red after the porcelain is fired, the black iron slag also sticks to the feet. This is a relatively low-level technique, and it can only deceive some beginners.

Zhuang Shengjing smiled wryly: "It seems that my eyesight is too bad, and I didn't even see such a flaw! However, since this jade pot and spring vase is so realistic, why did the maker add another thing?"

Regarding this question, Chu Chen and others were a little puzzled. They couldn't say that the producers didn't care about such a high-quality imitation, so they used it to test the production method of Flint Red, right?

Everyone looked at each other in blank dismay, unable to think of a reason for a moment.

Yuan Hongjian is a relatively open-minded person, and he never digs into a dead end. When he came back to his senses, he said: "Forget it, if you can't figure it out, don't think about it, but you should pay attention to those who are teachers. I think this person is still very problematic." of."

Zhuang Shengjing nodded. If Teacher Ren hadn't reacted and acted like that at that time, he wouldn't have fallen for such a trick.However, even if he knew that Mr. Ren had a problem, he couldn't go to the other party to settle the account. Not to mention that he jumped into this pit by himself, Mr. Ren could also say that he didn't know much about porcelain and misunderstood it, because he was proficient in porcelain. What is jade.

"Oops!" Suddenly, Du Yile's expression changed, and he exclaimed, then stood up and hurried into the back room.

The three of them were taken aback by Du Yile's sudden movement. After a while, Yuan Hongjian's mind was moved, and he said in surprise:
"You wouldn't have bought something from that teacher Ren, or listened to his advice, would you?"

Chu Chen and Zhuang Shengjing thought about it, and felt that there was a possibility. Of course, even so, they might not necessarily buy fakes. The key still depended on what Du Yile bought and how good his eyesight was.However, since the teacher Ren was suspected of playing tricks on Zhuang Shengjing, he should check the things he bought.

After a while, as Yuan Hongjian said, Du Yidong came out of the back room with his things in his arms.

Seeing this situation, Yuan Hongjian asked: "I said Laodu, you have been in the profession for so many years, and your level is not low. Why do you have to ask others how to buy things?"

Du Yile replied: "Aren't you talking nonsense? I study porcelain and only dabble in jade wares. There are many difficulties in collecting jade wares. Even if you like something, you have to ask others!"

For these words, everyone deeply agrees that there are many fake jade wares in the market, and the counterfeiting techniques emerge in endlessly, not to mention people who are new to jade wares collection, even some experts are also hard to distinguish the authenticity from the fake.

And if you want to learn jade identification, you need a lot of background knowledge.The shapes, decorations and usage methods of jade wares in each historical period are different. Collectors should not only memorize a large number of jade wares characteristics, but also understand the historical knowledge and archaeological data of each period, identify jade materials, and understand jade crafts in different eras. features.

This alone stopped many collectors who wanted to learn jade appraisal.

Therefore, the identification of jade is not a one-day job, but requires long-term accumulation of experience.It is not enough to simply look through the catalog of jade wares. You must first look at ancient jades, visit more museum collections, communicate with experts more, and persevere in order to gain something.

"Mr. Chu, I would like to trouble you to help me identify it..."

With that said, Du Yile opened a larger box, and there were three pieces of jade in it, namely a sapphire bear from the Han Dynasty, a jade bibill from the Ming Dynasty, and a jade pendant from the Qing Dynasty.

Chu Chen quickly said that there was no problem, then picked up the jade and observed it carefully.

These three pieces of jade, although the materials used are a bit inferior, but all of them have their own advantages, and they can be regarded as small best. However, because the three pieces of jade are not big, and the materials are not outstanding, the value It's not high, and it's about a hundred thousand in total.

"Du Lao, congratulations, these are genuine products!" Chu Chen smiled and nodded to Du Yile.

Du Yile breathed a sigh of relief when he heard the words. He had shown these pieces of jade to his friends before, but now that they have been affirmed by Chu Chen, there must be no problem.

"I also ask you to take a look at this Han Dynasty jade sword..."

Then, Du Yile opened another box, and what was inside was the jade sword he was talking about.

This sword is made of white jade, but it looks dirty overall, as if it hadn't been unearthed for a long time.The body of the jade sword is plain without ornamentation, the sword grid is embossed with Chi patterns, and the head of the sword is embossed with dragon patterns. The workmanship is done in one go. Judging from the carving work, it is undoubtedly the style of the Han Dynasty.

But as soon as the jade sword was used, Chu Chen immediately felt that the color of the jade sword seemed to be too white, and it was not like the performance that white jade should have. After careful observation, he found that the blade of the jade sword was not made of jade at all. .

"How is it?" Du Yi was happy to see that Chu Chen had finished reading, so he hurriedly asked.

Chu Chen shook his head: "This thing is not real!"

"really!"

Du Yile let out a long sigh, looking a little gloomy for a moment.But after all, he has gone through many storms, and with some preparations in his heart for such a result, he immediately adjusted his mood.

However, after all, he bought this jade sword with real money, so he had to figure it out, so he looked at Chu Chen again, wanting to hear what Chu Chen had to say.

Chu Chen said bluntly: "The blade of this jade sword is actually not jade, but nitrate."

"Glass?" Among the three, except for Du Yile who had heard about this thing, the others had never even heard of it before.

Yuan Hongjian quickly asked: "Mr. Chu, what is this nitrous?"

Chu Chen explained: "Glass is actually a kind of fake crystal made of ore. This thing has been imitated into jade for hundreds of years. Cao Zhao's "Ge Gu Yao Lun" in the Ming Dynasty introduced that "fake crystals are burned with medicine." The mature ones are dark blue in color, with gas eyes, or yellowish blue in color, and white in color, which are pure white and bright, which are called nitrates.'”

"Moreover, the ancients also said that 'jade must be superior to nitrate', which means that white jade must be like nitrate to be considered high-grade. From this, it can be seen that nitrate and jade are difficult to distinguish."

Yuan Hongjian asked again: "Then how to distinguish between the two?"

Chu Chen replied: "No matter how difficult it is to distinguish between true and false, they are different after all. In terms of color, the white of white jade is often bluish, and there are very few pure whites, while nitro is pure white that is even and pure white. As far as the nature of jade is concerned , the jade is warm and delicate, like fat and cream, although the glass is also warm and moist, there is inevitably a glimmer of light in the luster."

"The most important thing to mention is that white jade is a natural product, and it is difficult to have a uniform body, such as jade tendons and jade flowers in the inside. Glass is made artificially, so there is no such appearance. White jade is solid in texture and has no air bubbles to be found. Glass is processed again Well, there are often air bubbles and air holes exposed. For this, you can use a magnifying glass to look at these places..."
