Although I didn't think it was genuine, I couldn't resist Wu Er's urging.
Chen Wenzhe put on his gloves and carefully took out the things from the gift box.
This is really a heavy weapon, it feels very comfortable to hold in your hand.
This blue and white plum vase with cloud and dragon pattern is 41.6cm high, 6cm in diameter and 14cm in foot diameter.
The plum vase has a folded rim, a narrow neck, and plump shoulders. It gradually converges below the shoulders and has a circle foot.
The sole of the foot is unglazed and is flint red.
From top to bottom, the outer wall is divided into five layers with blue and white double string lines.
The shoulders are painted with curly grass patterns and drooping cloud shoulder patterns. The inner cloud shoulders are painted with intertwining chrysanthemum patterns, and the cloud shoulder patterns are decorated with curly grass patterns.
The abdomen is painted with cloud and dragon patterns, and the shins are painted with curly grass patterns and Yanglian petal patterns.
It can be said that Yuan blue and white flowers have everything they should have, but this is just the appearance.
The counterfeiting of Yuan blue and white porcelain began in the Republic of China, because at that time no one in the country believed that blue and white porcelain existed in the Yuan Dynasty, and they all thought it was something after the Ming and Qing Dynasties.
Therefore, no one had imitated it before, because the Chinese people did not know the existence of Yuan blue and white.
Isn't it ironic that this thing was discovered by foreigners?
The porcelain of Jingzhen only started to be marked down in the Yongle period of the Ming Dynasty, so the Ming and Qing porcelains after Yongle are very easy to confirm.
In the Yuan Dynasty before the Ming Dynasty, due to the short reign, it was not long enough to form its own characteristics and had no sense of style, so there was a lack of convincing objects to demonstrate the porcelain of this period.
It was not until 80 or 90 years ago that an Englishman named Pope, after comparing porcelain from Turkey and other museums, came to the conclusion of Yuan blue and white porcelain and published it.
The object of this main argument is the "elephant ear vase with blue and white clouds and dragon patterns".
Like this one, it also has a cloud and dragon pattern, and there is also a blue and white plum vase with a cloud and dragon pattern in the National Palace Museum.
This one was probably copied from that one.
Chen Wenzhe doesn't know that he is professional in judging the shape of a device by feeling it.
This blue and white plum vase is very delicate in workmanship, with clouds and dragons painted on it, and the image is quite distinct, but the shape of the vase cannot be said to be beautiful, especially the center of gravity, which is a bit tilted.
This is entirely due to the unqualified embryo-making process. This plum vase is more than 40 centimeters high.
The embryo is not good and cannot reach the master level. This is obviously different from the workmanship on the outside, including the blue and white and cloud-dragon patterns.
This kind of situation would not have happened in ancient times. How could the master who made such a tall and heavy weapon be an ordinary person?
This is the reason why Chen Wenzhe is unwilling to touch Yuan Qinghua. If he didn't have a super strong hand, how could he see some defects in the internal embryo?
Just looking at the blue and white exterior, the workmanship and the cloud and dragon patterns, I usually give in.
If you were not very good at it, you would probably have your heart pounding at this moment, thinking that you have met a national treasure.
Nowadays, many people know what the techniques of blue and white painting on the outside of Yuan Dynasty are like. It can be said that all the characteristics have become popular.
For example, there are curly grass patterns or cloud-head pattern trimmings, as well as wishful cloud-head patterns, banana leaf patterns, etc. But these things are all visible and can be imitated.
What cannot be imitated, or in other words cannot be imitated, is the fetus, which is also an important reason why many antique counterfeiters resort to counterfeiting.
The quality of Yuan blue and white porcelain is not as fine as that of Ming and Qing porcelain, so there are many blisters, brush marks and iron spots on the sand bottom, and the bottom foot, mouth edge and the exposed parts of the shrunken glaze appear flint red.
Also, the utensils of the Yuan Dynasty were made of Macang soil. After aging, trachoma is likely to appear on the bottom of the utensils.
Therefore, the real Yuan blue and white base tire looks very rough, but when touched by hand, it feels very delicate. This is the typical characteristic of Macang soil.
By this time, Chen Wenzhe had almost figured out the Yuan Qinghua routine.
This piece of porcelain seems to have master-level craftsmanship except for the body. This is not because of lack of skill, but because of the makang soil.
You must know that Ma Cang soil has disappeared now, and without Ma Cang soil, there is no way to imitate Yuan Qinghua.
If Chen Wenzhe guessed correctly, the inner tube of this porcelain should be a plum vase made of Macang clay.
It is definitely not from the Yuan Dynasty, but probably from the Ming Dynasty. You must know that before Wanli in the Ming Dynasty, there was still Macang soil.
That's right, the unknown master of counterfeiting used a Ming Dynasty utensil embryo, refired it in a kiln, and made a high-quality imitation of Yuan blue and white.
His porcelain making skills should be very good, but he had no choice but to use an old tire with slight flaws.
Such a high imitation of Yuan blue and white can easily deceive experts in the industry.
Chen Wenzhe glanced at Wu Er and really didn't know where he got this thing.
By this time, Chen Wenzhe became more serious.
In addition to looking at the tire, there is also a glaze. There are definitely differences between modern cobalt materials and Yuan Dynasty cobalt materials.
In fact, what has had a greater impact on the collection world are the imitations that have appeared in the past ten years or so.
Nowadays, the level of craftsmanship is much higher than in the past, and information is more developed. Counterfeiters can easily get access to genuine products through various channels.
Such conditions are better than those during the Guangxu, Xuantong and Republic of China periods in the Qing Dynasty.
However, the green material used in painting now is basically chemical green material, which is the chemical cobalt oxide.
In theory, relatively pure chemical green materials can produce any blue and white hair color, but in practice, it is extremely difficult to achieve this.
Cobalt oxide is black gray powder, light gray green powder, or peach red powder. The color of the prepared pigment is not equal to the color of blue and white after firing at 1300 degrees high temperature.
It is extremely difficult to deduce the cause (the ratio of cobalt oxide raw materials) from the result (blue and white color), and requires a lot of process exploration.
The coloring effect of cobalt oxide is relatively strong. One of the reasons why imitation Yuan blue and white is so popular is that the color of Yuan blue and white is also relatively strong and it is easy to get away with it.
Many collectors hide away when they see Yuan blue and white flowers, which must be related to this point.
After all, there is a big difference between chemical green materials and natural Suma Liqing.
Chemical green materials are relatively pure, while suma-liqing contains many impurities. It will definitely not be easy to use chemical green materials to prepare suma-liqing.
As a result, high imitators will have to spend a lot of money if they want to cover everything.
They are here to make money, not to pursue art, so they still won't do many details even though they know they may be discovered.
For example, this piece of Yuan blue and white has two main flaws. One is that the shape of the vessel is not regular, and the other is that the blue and white material imitates Suma Liqing.
As for the pockmark soil exposed from the bottom tire, it is real and no one can find the problem.
In fact, the most important things to identify Yuan Qinghua are two things, Su Ma Li Qing and Ma Cang Tu. As long as these two conditions are met, everything else is trivial.
Through this piece of Yuan blue and white, Chen Wenzhe gained some insights.
