My system is not decent

For example, blue and white hair color, Yuan blue and white hair color has three types: rich, elegant, and blue gray.

The rich and colorful is made of imported Sumali green material, and the elegant is a mixture of imported and domestic materials.

A considerable part of the blue and white has black spots and is darker after firing.

The most authentic Yuan blue and white are made of imported Sumaliqing material, and Sumaliqing material has a characteristic, that is, high iron and low manganese, the blue and white are deep blue with a little purple, and the green is slightly green.

And this is also Chen Wenzhe's main goal in the later stage.

It turns out that this point is easy to be seen by others, but now that he has a layer of impurities on it, plus the processed blue and white color, it is difficult to find the problem if you want to look here.

Now the color is right, it depends on the crystals contained inside.

Here, another pit.

It is really not easy to complete the real high imitation yuan blue and white.

The "Sumaliqing" used in the Yuan Dynasty is mainly composed of cobalt oxide and a small amount of iron oxide.

Under the action of high temperature, the iron oxide in "Sumaliqing" will aggregate in the silicate liquid to form dark crystal spots.

Observed under a microscope, most of them are irregular sauce brown spots sinking under the glaze.

However, most modern imitations simply add iron oxide powder to domestic blue and white.

Under the action of high temperature, these iron oxides will quickly float to the surface of the glaze to form crystals.

On this point, the faker did a good job, and Chen Wenzhe wasn't worried at all.

The next thing is simple, after looking at a few important points, the rest is to look at the device type.

For example, most of the blue and white flowers in the Yuan Dynasty have wide and short ring feet. Generally, the bottom and inside of the utensils are not glazed, but most of the utensils and the bottom of the utensils have glaze spots.

In addition, most of the carcasses of Yuan blue and white pots and bottles are four sections and three connections, and there are also five sections and four connections.

The joints are on the bottom, abdomen, and neck, and the joints are glued with mud. There are obvious protrusions at the joints, and traces of mud extrusion can be seen at the joints.

These obvious features are better imitated.

Especially flint red, it is perfect without imitation.

When looking at porcelain, look at the bottom first, and at the end, you still have to judge the authenticity of porcelain by the exposed part of the bottom of the bottle.

The bottom of the blue-and-white wares in Yuan Dynasty is not glazed, so it is called rough bottom or sand bottom. The signal transmitter is hidden in one of the trachoma.

Of course, if you don't destroy it, you won't be able to find it.

Moreover, everyone's eyes are now attracted by the red spots on the rough surface, which is commonly known as the phenomenon of flint red, and they would never think that there are evil intentions here.

As long as the signal transmitter is not exposed, they can look at the bottom of this plum vase however they like. Anyway, this is a pure old bottom!

Therefore, the more they look at it, the more they are satisfied, because the characteristics of this piece of porcelain are really good.

This kind of real natural aging phenomenon, if Chen Wenzhe is made old, he really can't do it to this extent.

At this time, he felt a little impulsive to upgrade his old-fashioned skills.

However, he held back, because it required too many skills to make an old piece of Yuan blue and white.

Not to mention the blue and white hair color, there are also tire mud, vessel shape, decoration, mouth edge, flint red, crystallization, etc., all of which must be old.

Therefore, it is very difficult to really imitate a piece of Yuan blue and white.

Let’s just talk about Chen Wenzhe, if he hadn’t encountered this high imitation Yuan blue and white, he would never have thought of imitating one by himself, because it was too difficult.

Just like now, the little devil Fujino Shoji has made a fool of himself again.

He actually took out a camera that can take pictures from a bag, and it also has a searchlight. What is this?

When he first saw such high-tech equipment, Chen Wenzhe hadn't reacted yet, but he soon realized that something was wrong.

That probe can penetrate deep into the plum vase.

The plum vase is a wine vessel, which was later developed into an ornamental product. Its mouth is so small that Chen Wenzhe himself didn't even think about checking the inside of the plum vase through the mouth.

But the little devil just thought of it, and he used high-tech equipment.

At this moment, Chen Wenzhe was absolutely guilty. What he was most afraid of was that the master of fraud would be Tailang.

In case he can't think about it alone and wants to leave a name on this blue and white piece of Yuan Dynasty, such as Qiaoshou Liu or something, then this time he will reveal his secret.

It was too late to say anything at this time, and I could only resign myself to fate.

Things are not bad, as the probe goes deeper, the first thing you see is a light red flint red.

Seeing this situation, Chen Wenzhe was overjoyed.

This is professional. If you stay steady and don't waste money, he will definitely make a fortune.

This Yuan blue and white piece is a pure high imitation, even the inner wall is a very good imitation.

In other words, this is a natural situation, that faker didn't move his inner tube at all!

After all, this is an old tire with a new fire, and the internal situation is deliberately full, which is normal.

The inner wall of Yuan blue and white is generally not glazed, only a light flint red.

In the production process, there are still some artificial traces.

This is very clear under the illumination of the camera.

While checking, Fujino Soji also took a lot of photos.

Zoom in on the photo to see it more clearly, so some artificial traces can be seen more clearly.

For example, some traces of cleaning, or even some fingerprints and fingerprints.

Unexpectedly, the shape of this Yuan blue and white vessel is not very good, but some small details inside are handled very well.

At the very least, all the artificial traces inside are left.

It doesn't look like it was done on purpose, it should have been there before, and this can be regarded as an unintentional detail that got it right.

Therefore, to make a high imitation of Yuan blue and white, one must start with the practice of clay, otherwise, if there is a problem in any link, it will be identified by others.

It is more difficult to deliberately fake the fingerprints left on the inner wall of the plum vase.

Many people don't think that with such a small bottle mouth, who can see what's inside?

Now, Fujino Shoji saw it.

Seeing the internal situation, Fujino Shoji was obviously very satisfied.

Artifacts in the Yuan Dynasty were mostly drawn by hand or stripped into shape, so that it was inevitable to leave obvious fingerprints and swirls on the inner walls of bottles, cans and other utensils.

If no fingerprints and swirls are found on the inner wall of the utensil, it is a low-grade imitation produced by modern grouting molding technology.

In addition, anyone who knows Jingzhen’s ceramics production process knows that there are two types of knives used for trimming, one is called "strip knife", which is used to trim the inner wall of the utensils;

One is called "board knife", which is used to trim the outer wall and foot ring of utensils.

The appearance of "ban knife" has a history of at least more than 2000 years, while "bar knife" only appeared during the Kangxi period of the Qing Dynasty.

In other words, the porcelain before Kangxi only repaired the outer wall, not the inner wall.

After the mid-Kangxi period, the inner wall of the porcelain began to be trimmed.

Some imitators don't understand this, they just make it according to the catalog, and often superfluously trim the inner wall.

Therefore, if you see the modified inner wall of Yuan blue and white, it is an imitation.
