My system is not decent

There are too many pitfalls in Chapter 181 (both order 300 plus updates)

The price of Yuan blue and white is too high, and the quantity is very rare. No one wants to give up when they encounter it. However, everyone who encounters Yuan blue and white can't be too cautious.

Especially in recent years, the Yuan blue and white craze in the field of ancient porcelain collections has continued to heat up. It can be said that there are hundreds, thousands, or even tens of thousands of "Yuan blue and white" in the domestic market and in the hands of collectors. Many ancient porcelain lovers are at a loss.

The blue-and-white porcelain of Yuan Dynasty mentioned in the world of ancient porcelain and the identification of blue-and-white porcelain of Yuan Dynasty generally refers to the blue-and-white porcelain of Yuan Dynasty in Jingzhen.

The blue and white porcelain of the Yuan Dynasty in Jingzhen can be divided into "Zhizheng" high-quality porcelain painted with imported Sumali blue material and ordinary porcelain with domestic blue material.

It turns out that this piece of porcelain is made of domestic chemical green material, which can be easily recognized by people.

But now after Chen Wenzhe's cover-up and transformation, ordinary people really can't recognize it.

At the very least, top experts who are not often in contact with genuine Yuan blue and white products will definitely not be able to recognize them.

Chen Wenzhe still has this confidence.

However, the so-called experts in the market are afraid of being deceived, so no matter who encounters Yuan Qinghua, they are very cautious.

If it weren't for this, Wu Er's high imitation should be easily fooled by him.

However, if you want to sell at a high price, you will naturally face high risks, so as long as you are a slightly cautious buyer, you will not be fooled.

Now it's in Chen Wenzhe's hands. He has reformed it a bit to see if he can fool these little devils.

At this time, Fujino Sooji carefully lifted the plum vase. He held the thing in his hands and carefully felt the weight of the plum vase.

Especially the bottom of the bottle, if it is connected to the bottom, the bottom of the bottle will inevitably become heavier. If you feel it carefully, you will find a slight incongruity, and even the abnormal weight can be felt.

From this small action, Chen Wenzhe knew that this guy still knew Yuan Qinghua very well.

Pick it up, not only to look at the bottom of the bottle, but also to evaluate the entire shape.

You must know that the blue and white porcelain of the Yuan Dynasty was heavy and firm, with thicker walls and more large vessels.

Therefore, the light and fluffy ones are definitely not Yuan blue and white. As for the glaze color, they can't see anything.

The chemical blue material used in the past, although the gray is clear, it can be regarded as the authentic Yuan blue and white hair color, but if you look carefully, you will find that the blue and white are very pure, but now there are impurities and Baoguang.

And this impurity is not only manifested on the blue and white material, but also manifested in the fetus.

Due to the many impurities, there are mostly iron-brown dots in the fetus. Chen Wenzhe didn't need to do these, the original master has already done it perfectly.

"The fetus is made of kaolin Machang soil."

"White but not fine, that's right!"

"Well, you can see a lot of air holes!"

Kaolin Machang soil is characterized by being white but not fine. Because the crushing conditions and techniques were limited at that time, many pores can be seen.

Today's tires are very thin and have no pores. The old tire mud in the past has undergone a process of aging, and the organic matter will change after aging.

Therefore, its tires have a delicate feeling, and the tires made now are not stale and dry.

These characteristics are very obvious, because this is an old tire and old mud, not old porcelain.

"Not much retouching!"

"There are some traces, but there are relatively few repairs!"

Chen Wenzhe listened to the discussion between Fujino Zongzhi and Qian Kaiming, and found that they really had something.

"Isn't it three-point stretching and seven-point trimming?" Honda asked curiously.

"On the contrary, the plasticity of the porcelain-making raw materials processed by modern machinery is generally not as good as that of the raw materials prepared by hand in the Yuan Dynasty. The popular ceramic molding process in modern Jingzhen is said to be: three parts for casting and seven parts for trimming.

That is to say, the shape of the utensils is mainly repaired with a knife, but the craftsmanship of the Yuan Dynasty is just the opposite. That's right, the fetal soil is fine, and with the manufacturing process, it can be said that there are no flaws. "

Chen Wenzhe had learned the manufacture of Yuan blue and white in his dream, but it was only basic manufacturing, so he also knew some basic techniques.

However, Chen Wenzhe knew that Fujino Zongji was right, and he probably had a deep research on Yuan Qinghua.

However, no matter how much research you do, it's useless if you haven't really tried it.

In fact, there is a contradiction here. The walls of large blue and white utensils are relatively thick, but when the embryo is drawn, it can be drawn very thin.

This is mainly due to the strong plasticity of the clay in the Yuan Dynasty, so it can be pulled very thin.

Therefore, the upper half and the interior of the utensil do not need to be trimmed at all, but the lower half and the ring feet need to be simply trimmed.

Therefore, the mouth edges and necks of Yuan Dynasty utensils have smooth lines, round shapes, and no knife marks.

The drawing of the modern imitation is very thick, not only the upper part, but also the inner wall must be repaired.
Therefore, the lines are blunt, more than regular, and full of knife marks.

It's a pity that this piece is very neatly made, perhaps because the embryo was too thin when it was drawn, so the entire embryo was slightly deformed during firing.

This is also something that can’t be helped. The skill of the ancient people is to advance through exploration.

Most of the time, they just try their luck when firing porcelain. If they are unlucky, the shape of the fired porcelain will change a little bit. What can you do?
Such a situation is generally called a kiln change!
This is what Chen Wenzhe is most afraid of. If he finds a problem with the shape of the device, it will probably arouse suspicion. At that time, he will feel wrong everywhere he looks.

Obviously, it is not a professional ceramic craftsman, and it is not easy to find the problem of the shape of the vessel.

So, at this time, Fujino Shoji and Qian Kaiming had already begun to study the air bubbles in the blue and white.

It turned out that Chen Wenzhe hadn't thought of this point. After discovering that they were studying so seriously, Chen Wenzhe realized that there was also a big flaw in the bubble.

It's just that the flaws are not too obvious. Since they didn't find the problem of the shape of the vessel, they certainly won't find the problem of the kiln.

The old blue and white flowers of the Yuan Dynasty were all fired in firewood kilns, but now most of the imitations are fired in air kilns. The two processes are different, and the chemical changes and physical changes of the enamel are also different.

Especially in the formation process of the bubbles in the glaze, it is different. The bubbles fired in the ancient firewood kiln should appear to be of different sizes, and the bubbles are bright.

The air bubbles fired in modern gas kilns are thinner, alternate in size, and opaque.

This is only relatively speaking. If modern counterfeiters use firewood kilns to imitate utensils and conduct in-depth research on the shape and decoration of utensils, it will be difficult to judge the authenticity.

After Fujino Soji took out the magnifying glass, Chen Wenzhe breathed a sigh of relief again.

Don’t look at the bubbles anymore, now you can look at the crystals inside the glaze.

In this regard, Chen Wenzhe is still very confident, because the faker is very qualified.

It can also be seen from this that if you don't touch Yuan Qinghua, you won't touch it, because there are too many pits in it.
