My system is not decent

How big can a small piece of porcelain be inlaid on a necklace?

A small thing with a diameter of two or three centimeters can be sold for 70 yuan. Do you think there are any artificial fakes?

Not to mention the folks, even the official ones, there are many imitations.

The celadon porcelain of official kilns in the Northern Song Dynasty was very popular with the emperors of the Qing Dynasty because of its high artistry and noble character of court porcelain.

Therefore, the imperial kiln factory in the Qing Dynasty had imitated a large number of them.

At that time, it was called "factory official equipment", that is, it mainly imitated the celadon of the official kiln of the Northern Song Dynasty.

Jingzhen has a strong material and technological foundation. It imitates official kiln celadon, and most of them are palace furnishings.

The workmanship is meticulous and exquisite.

It is characterized by white-bodied green glaze, and the glaze color is azure.

If this kind of utensils were officially imitated by the imperial kiln factories in the Qing Dynasty, if they are complete utensils, they must be carefully identified.

But with tiles, it's not that much of a hassle because the inner tube is visible.

Therefore, just looking at it for a while, Chen Wenzhe knew that this could not be an official imitation of the Qing Dynasty.

As for other dynasties, there is no one that fits the characteristics.

Then there is the feel of the hand. In the old society, antique dealers imitated the real product and made it meticulously. The imitation product burned out was always different from the real product.

Generally, it feels a little light, which is due to the raw material processing is not fine, the stale time is short, and the tire quality is loose and not dense.

Genuine official kiln wares are different from Yuan blue and white. Its raw materials are finely processed, maturely controlled, fine-grained, and aged for a long time. The tire material is dense and heavy, so it feels heavier in the hand.

Official kiln wares are fakes, and the imitators want to increase the weight of the work. Because of the short time, the weight of the ancient porcelain texture cannot be produced.

Therefore, they gradually thicken the carcass from the edge of the utensils during molding.

Especially the bottom is thickened, which can increase the weight.

However, the lines of utensils will inevitably change, lose their due elegance, and become stiff and lifeless.

As long as you touch the bottom of the mouth with your hands, you will feel that the wall of the device is very thick and something is wrong.

Use a small stick to insert into the device and measure the height of the inside and outside of the device. If you look at the difference in size, you will find that the bottom is very thick and uncoordinated. This is the illusion of heavy hand feeling.

And looking at the tiles, you don't have to be so troublesome, you can see it with a little attention.

Of course, this alone cannot determine the authenticity, it can only be used as a reference.

Because there is a kind of factory in modern times, called the tire mud factory, which specializes in the production of tire mud, and if you provide the mud tire formula, he can produce any tire mud you want.

For example, if you want some official kiln body mud and provide a detailed composition ratio, then they can produce it for you, which is exactly the same as the real official kiln body mud.

Therefore, those who say in the video that by analyzing the composition of a piece of porcelain to determine whether it is an antique, it is purely a fool!

There is no problem with the feel and tire mud, but the glaze layer is the last thing to look at.

Chen Wenzhe had seen it before and thought it was very beautiful, but he also needed to look for it again to see if it might be artificially made.

You know, his old-fashioned level cannot make old antiques from the Song and Yuan Dynasties.

Therefore, if he really wants to achieve the level in front of him, it is impossible for him to identify it.

Looking at the glaze layer, the authentic Northern Song official kiln celadon has a good degree of vitrification and a beautiful and pleasing brightness.

For fake products, the glaze layer is relatively thick, and the glaze is also lustrous, but the degree of vitrification is not enough, and it is not as bright as the official kilns of the Northern Song Dynasty.

At first glance, the glaze color is also pure, almost too pure, but when observed with a magnifying glass, the glaze plate is stagnant, slightly yellowish, and has a feeling of being uncooked.

This is also to reduce the temperature, or add a reducing agent, to avoid the floating and stealth of the fired celadon glaze.

At this point, Chen Wenzhe was a little uncertain, because he had never seen the real official kiln wares, so naturally he didn't know what the real ones looked like.

However, he still knows some salient features.

For example, is the glaze dull and yellowish?

Also, is there a flaw in the kiln firing that creates a feeling of undercooking?

These are his strengths. Once you have seen the glaze, you have to look at the slices. This is a pitfall that cannot be avoided by official kilns and Ru kilns.

Chen Wenzhe has never seen the real product, but he knows the flaws of the imitation product.

These don't need to be studied hard, as long as you are willing to work hard and write them down.

He knew that imitations had fewer glazed pieces and shallower grains.

Some flakes are white, just like the flakes that appeared when the glass was just broken.

A few have been processed to form a light yellow color, with only one tone, and the effect of gold wire and iron wire cannot be obtained.

The real product has large and small flakes, the large flakes are dark brown and black, that is, iron wire, and the small flakes are yellowish brown, very light in color, with the effect of gold wire and iron wire.

Another advantage of looking at the tiles is that you can see the thickness of the glaze layer.

At this point, it is also easy to identify the authenticity of the official kiln.

Official kiln imitations are glazed thickly and neatly, so they are rarely fired with foot-wrapped branches, because it is too complicated and difficult to control.

Therefore, most of the official kilns use pad cakes, washers, and a few use nails. The nails are very large.

The real ones include foot-wrapping sticks, nails, and cake pads. The craftsmanship is more complicated and the workmanship is very fine, which is beyond the reach of imitations.

You know, Chen Wenzhe has professionally studied kiln firing technology, and it is definitely a master-level technology. Even after several intensive studies, his kiln firing technology is a little bit to break through the master level and reach the level of a master. trend on.

Therefore, judging from the glaze layer, he has the master-level technique of glazing, but judging from the level of kiln firing, he is at the level above the master.

At this point, no one should be able to hide it from him.

It is just a small piece of porcelain, and there is really nothing to see, only the clay body, glazing, opening, glaze layer expression and firing process.

This is not a complete vessel, but just a small piece of broken porcelain. Through the cross section, the authenticity can be easily identified.

After careful re-appraisal, Chen Wenzhe believes that this is a fragment of celadon from an official kiln in the Northern Song Dynasty, the real thing!

"If the identification is correct, the achievement value will be increased by one."

Chen Wenzhe breathed a sigh of relief. This time, he felt that his appraisal level had also increased.

Sure enough, after checking the attribute list for a while, Chen Wenzhe found that his identification technique had been upgraded from the basic level to the professional level two.

It was at this time that countless information flooded into his brain again.

Self-study upgrade, but also get the knowledge instilled in the system?

Now that Chen Wenzhe was already experienced, he immediately sealed all this information deep in his brain with a thought.

These identification knowledge will only be sorted out and learned when he is free.

Looking at the small porcelain in his hand, Chen Wenzhe felt a little emotional.

This is the first time he has obtained five famous kiln wares, even if there is only a small piece of broken porcelain, it is enough to make him happy.
