Chapter 980 The problem of blue and white materials
Chu Chen was very interested in these two pieces of bamboo root carvings, but at this time he was too embarrassed to keep them alone, so he asked other people for their opinions.

Needless to say, Uncle Wu, both Zhao Xueyi and Yuan Hongjian said that they didn't need it. Among them, Zhao Xueyi was because he had already gained something today, while Yuan Hongjian was not very interested in bamboo root carving works.

So, Chu Chen negotiated the price with Fu Lilei, but the other party didn't say anything, and everyone was happy in the end.

When Chu Chen's side completed the transaction, Chen Dewang finally put down the magnifying glass in everyone's eyes.Everyone didn't say anything about it. After all, this thing is very valuable, and it is quite normal to carefully appraise it.

However, after Chen Dewang looked at it, he frowned slightly, and his eyes flashed a little puzzled, which made everyone feel a little strange. Is there something wrong with this Longquan kiln plum celadon dish?
At this time, Fu Lilei was frightened like fifteen buckets fetching water. He hurriedly asked, "Old Chen, is there something wrong with this thing?"

Seeing his nervous appearance, Chen Dewang gave him a calm look, and said, "Xiao Fu, don't worry, the thing must be genuine. I just think there is something wrong with the patina."

"What? Could it be that this thing is old with patina again?" Hearing what Chen Dewang said, Fu Lilei's face immediately changed. If it was made with patina again, the value would be reduced by another third. It is said that if you make money, you can thank God if you can not lose money.

Uncle Wu hesitated and said, "Old Chen, I think this patina is quite natural, shouldn't it be made artificially?"

Chen Dewang nodded and said: "I also think it is formed naturally, but after looking at the patina before, I think the patina of this thing is a bit strange."

When everyone heard that this was the case, they all became interested and began to observe one by one.

After Uncle Wu and Zhao Xueyi observed it, it was Chu Chen's turn. He took the things in his hands and observed them carefully. He saw that this longquan kiln plum celadon glazed dish was light and beautiful in shape, and its texture was fine and dense.

This is because the Longquan Kiln in the mid-Southern Song Dynasty improved the tire soil formula, and added a proper amount of purple gold soil to the porcelain stone, which increased the content of alumina and iron oxide, improved the bending resistance, and was not easy to deform at high temperatures, making the tire blank thinner and overcoming The shortcomings of "bulky and thick" in the early Southern Song Dynasty were eliminated.

Besides the glaze, the Longquan kiln in the mid-Southern Song Dynasty also improved the formula of the glaze, changing from the original lime glaze to lime alkali glaze.Lime alkali glaze is characterized by high viscosity at high temperature and is not easy to flow, which can make the glaze layer thicker and make the appearance of the utensils more full.In order to obtain the best effect, the craftsmen adopted the complex process of multiple times of biscuit firing and multiple times of glazing, so that the glaze layer becomes richer and the color is more stable.

This vessel has a thicker glaze layer, a bright glazed surface, a high degree of vitrification, no cracks on the glazed surface, and a jade-like quality, which also conforms to the craftsmanship of Longquan kiln plum green glaze in the mid-Southern Song Dynasty.

In addition, in the mid-Southern Song Dynasty, Longquan kiln wares paid attention to tire repair, and the ring feet were repaired very thinly. The thin lines of glaze were scraped off on the bottom feet, and after firing, a circle of thin lines of vermilion appeared, commonly known as "cinnabar bottom", which gave celadon porcelain a unique charm. .

The exposed part of the sole of the foot of this device is purple, which is a typical feature of the cinnabar bottom.

In addition to the above three points, Chu Chen carefully observed the decorations and firing techniques of the things, and finally he was sure that this Longquan Kiln Plum Celadon Glazed Folding Plate is indeed an authentic piece from the Southern Song Dynasty, and it is still quite rare. treasures.

However, as Chen Dewang said, there seemed to be some problems with the patina of this utensil. Chu Chen observed it carefully and knew it.

During this period of time, because of the patina, he basically focused his energy on the study of patina. Therefore, although he was not [-]% sure about the patina on the object in front of him, he still had a basic judgment.

Then, after Yuan Hongjian observed, Chen Dewang asked, "What do you think?"

Everyone looked at each other, and Uncle Wu looked at Chu Chen and said, "Xiao Chen, you come first."

Chu Chen smiled, declined, and said directly: "I think this thing should be an unearthed cultural relic. As for the time when it was unearthed, it should have been several decades, but because of storage reasons, it seems a bit strange. "

"Xiao Chen, what is the basis for your judgment?" Chen Dewang asked curiously, and the others also looked at Chu Chen, waiting for him to give an answer.

"I think so for several reasons."

Chu Chen explained with a smile: "First of all, I think the place where this thing was originally buried has become shallow buried due to some special reasons, such as water and soil erosion, so its surface has also oxidized, but Maybe the oxidation time is not long, which caused it to fail to achieve the performance of a general heirloom."

"In addition, after the porcelain is unearthed, the formation of the patina will also be affected by various aspects, such as washing, handling, storage and so on."

"For example, washing. Some things were unearthed and washed within a few minutes after they came out close to the water source. Some things were washed with various chemicals such as potassium permanganate or 84 washing liquid as soon as they moved home. Some things It takes a few days to more than ten days or even longer to soak once, and the patina of many things is washed away by the full soak.”

"Also, due to the length of storage time and the different locations, the appearance of the utensils is also different. Some are placed in ventilated and light-transmitting houses, and some are placed in ventilated or airtight cellars, haystacks, etc. Both will affect the formation of patina, so the presentation of patina will be different..."

Hearing this, Yuan Hongjian said: "Mr. Chu, according to what you said, there are so many patina surfaces, so how should we usually distinguish between the authentic and the fake?"

Chu Chen replied: "What I just said is that the appearance of the patina is different, but they are actually the same in one thing, that is, the patina is formed naturally, and the identification of the false and the authenticity can be cut from this point. As for other aspects , I should have introduced it to you before."

Yuan Hongjian nodded to indicate that it was indeed so.

At this time, Chen Dewang said: "Xiao Chen, do you think there are any traces of human manipulation on the patina of this thing?"

Chu Chen smiled and said, "Of course there is!"

"What!" Fu Lilei's face changed after hearing this, and he almost jumped up in fright.

Chu Chen smiled and said, "Boss Fu, don't get excited. What I'm talking about is that this plate was cleaned by the original owner in an unscientific way, which caused some impact on the patina."

Hearing that this was the case, Fu Lilei breathed a sigh of relief immediately, and Zhao Xueyi said with a smile: "Xiao Chen, don't just half-talk the next time you speak, or if you encounter someone with a bad heart, it may be all right now." Gotta call an ambulance."

"Understood, understood..."

Everyone laughed, and then, Chu Chen went on to explain in detail why he thought so, and everyone agreed after listening.

With no doubts about the patina, Chen Dewang felt relieved about this rare plum celadon porcelain. Afterwards, he and Fu Lilei went to the side to bargain, and finally completed the transaction at a price that both parties were satisfied with.

After the transaction was completed, everyone was about to leave. Fu Lilei asked, "Mr. Chu, what should I do with my two old things that are wrapped in slurry?"

Chu Chen replied, "Leave it alone."

"Okay." Fu Lilei nodded, and then asked hesitantly: "Then these two genuine items will not be confiscated in the future?"

Chu Chen was slightly taken aback. He really didn't think about this issue just now, but if these things were indeed obtained illegally by the gang, they would definitely be confiscated according to the current law, but Fu Lilei didn't know about this matter. If it is confiscated, no matter who it is, no one will agree.

Chu Chen scratched his head and said, "Forget it, just sell that thing to me, and I'll take care of it when the time comes. Mr. Chen, how about giving me yours too?"

Chen Dewang said with a smile: "It's nothing to give you, but you have to answer me first, what are you going to do with the things?"

Chu Chen replied: "Isn't my private museum being prepared, and these two things will be put on display there then."

Chen Dewang was about to speak when he heard the words, Fu Lilei said quickly: "Old Chen, how about this, I will give these two things to Mr. Chu at the cost price."

Chu Chen smiled and said, "Boss Fu, you are anxiously waiting for the money now, so there is no need for that."

Fu Lilei waved his hand: "After dealing with this Longquan kiln, I am not nervous about the money in my hand, you have to agree no matter what!"

In other words, as a commoner, he would definitely not be able to keep things confiscated at that time. Now that Chu Chen handled it this way, it will undoubtedly save him a lot of trouble and save his money. Of course he has to reciprocate, and he can Forging a good relationship with Chu Chen will always be beneficial in the future.

Seeing that Fu Lilei insisted on this, Chu Chen could only agree.

Afterwards, Chen Dewang expressed that he wanted to see these two items, but when they were taken out, his attention was always on the vase imitating the outing of the Ming Dynasty Wanli Blue Flower Epiphyllum.

After a while, Chen Dewang frowned and said, "This blue vase is interesting!"

"What's interesting?" Zhao Xueyi asked.

Chen Dewang pointed to the blue vase and said: "Compared with the real Huiqing material, the hair color of this blue vase is at least [-]% similar in my eyes. What do you think this means?"

Except for Chu Chen, everyone else present was stunned. They hadn't really thought about this question just now, but now that they came to their senses, they were surprised and worried.

Even an experienced old man like Chen Dewang feels that there is at least [-]% similarity, so for novices, it is basically difficult to tell which is true and which is false.

Chen Dewang went on to say: "Besides, the body glaze and painters you look at are not [-]% consistent with Wanli blue and white porcelain, but they are at least [-]% similar. When will another such powerful figure appear on the market?" Are you a master of antique porcelain?"
