A small piece of porcelain can be mounted on a necklace. How big can it be?
A small thing with a diameter of two to three centimeters can be sold for 700,000 yuan. Do you think it is artificially fake?
Not to mention the private sector, even the official ones are imitating many of them.
The celadon from the official kilns of the Northern Song Dynasty was very popular among the emperors of the Qing Dynasty because of its high artistic quality and the noble character of palace porcelain.
Therefore, the imperial kiln factories in the Qing Dynasty copied a large number of them.
At that time, it was called "factory official ware", which mainly imitated Northern Song Dynasty official kiln celadon.
Jingzhen has a strong material and technological foundation. It imitates official kiln celadon, mostly for palace display porcelain.
The workmanship is meticulous and very exquisite.
It is characterized by a white body celadon glaze, and the glaze color is azure.
If these official imitations of the imperial kilns of the Qing Dynasty are complete, they must be carefully identified.
But for porcelain tiles, it's not that troublesome because the inner tube can be seen.
Therefore, with just a quick glance, Chen Wenzhe knew that this could not be an official imitation of the Qing Dynasty.
As for other dynasties, none of them fit the characteristics.
Then it depends on the feel. In the old society, antique dealers imitated the originals and worked meticulously. The imitations they produced were always different from the originals.
Generally, it feels a little light, which is caused by the raw materials not being processed finely, the aging time being short, and the texture being loose and not dense.
Genuine official kiln ware is 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 particles are dense and have a large specific gravity, so it feels heavier when you hold it. This generation is exactly the opposite of Yuan blue and white.
The fake official kiln wares are imitated in order to increase the weight of the work. Due to the short time, the hand-feel of ancient porcelain cannot be reproduced.
Therefore, they gradually thickened the carcass from the edge of the utensil down during molding.
Especially thickening the bottom can increase the weight.
However, the lines of the utensils will inevitably change, losing their due elegance, and the lines of the utensils will 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 container and measure the height of the inside and outside of the container. If you look at the difference in size, you will find that the bottom is very thick and uncoordinated. This is the illusion of a heavy hand feel.
When looking at porcelain shards, you don’t have to worry so much. You can tell with just a little attention.
Of course, this alone cannot determine the authenticity, it can only be used as a reference.
Because there is a modern factory called a tire mud factory, which specializes in producing tire mud, and if you provide the mud tire formula, it can produce any tire mud you want.
For example, if you want some official kiln tire mud and provide a detailed ingredient ratio, they can produce it for you with the same ingredients as the real official kiln tire mud.
Therefore, those who say in the video that one can determine whether a piece of porcelain is an antique by analyzing its composition is simply deceiving fools!
The feel and tire mud are fine, but the final step is to look at the glaze layer.
Chen Wenzhe had seen it before and thought it was very beautiful. However, he also needed to look for it again to see if it might be artificially made.
You must know that his level of distressing is not enough to distress antiques from the Song and Yuan Dynasties.
Therefore, even if someone could really reach the level in front of him, it would be impossible for him to identify it.
Looking at the glaze layer, the genuine Northern Song Dynasty official kiln celadon has a good degree of vitrification and a beautiful and pleasing luster.
The fake product has a thicker glaze layer and a glossy glaze, but the degree of vitrification is not enough and it does not have the brightness of the official kilns of the Northern Song Dynasty.
At first glance, the glaze color is pure, almost too pure, but if you observe it with a magnifying glass, you will feel that the glaze surface is stagnant, slightly flashing yellow, and has a feeling that it is not cooked.
This is also done by lowering the temperature or adding reducing agents to prevent the glaze of celadon from becoming shiny when fired.
At this point, Chen Wenzhe was a little unsure, because he had never seen authentic official kiln wares, so he didn't know what the authentic ones looked like.
However, he still knew some of the salient features.
For example, is the glaze dull or yellowish?
Also, were there any defects when the kiln was fired, resulting in an undercooked feeling?
These are his strengths. After looking at the glaze, you have to look at the opening. This is a pitfall that neither Guan Kiln nor Ru Kiln can avoid.
Chen Wenzhe has never seen the real thing, but he knows the flaws of the imitation.
These do not require much effort in studying, as long as you are willing to study hard and write them down.
He knew that the imitation glaze had fewer flakes and shallower flakes.
Some of the flakes are white, just like the flakes that appear when glass is just broken.
A few are processed to form a light yellow color, which only has one tone and cannot produce the effect of gold wire.
The texture of the authentic piece is that the large piece and the small piece are staggered. The large piece is dark brown and black, which is the iron wire. The small piece is yellowish brown and very light in color, with the effect of gold wire.
Another advantage of looking at porcelain shards is that you can see the thickness of the glaze layer.
This makes it easy to identify the authenticity of official kilns.
The official kiln imitations have thick glazes and neat glazes, so it is not common to use a foot-wrapped foot for firing, because it is too complicated and difficult to control.
Therefore, most official kilns use cushion cakes and washers, and a few use support nails. The support nails are very large. After the support nails are broken, white tires are exposed in the damaged areas of the glaze.
The authentic product has foot-wrapped legs, nails, and pancakes to support the oven. The craftsmanship is relatively complex and the workmanship is very fine, which cannot be achieved by imitations.
You must know that Chen Wenzhe has learned kiln-firing technology professionally, and he is definitely a master-level technique. Even now, after several times of intensive study, analogy, and comprehensive understanding, his kiln-firing technology has somewhat surpassed the master level and reached the level of master.
trend on.
Therefore, looking at the glaze layer, he has master-level glaze application skills, but looking at the level of kiln firing, he is above the master level.
At this point, no one should be able to hide it from him.
It's just a small piece of porcelain, and there really isn't much to see, only the clay body, glazing, opening, glaze layer expression and firing process.
This is not a complete vessel, but a small piece of broken porcelain. Through the cross section, the authenticity can be easily identified.
After careful re-identification, Chen Wenzhe believed that this was a fragment of Northern Song Dynasty official kiln celadon, a genuine piece!
"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 improved.
Sure enough, after looking at the attribute list, Chen Wenzhe discovered that his identification skills had been upgraded from basic level one to professional level two.
It was at this time that countless information poured into his brain again.
Can I upgrade myself through self-study and gain knowledge from the system?
Chen Wenzhe was now considered to have rich experience, so he immediately sealed all this information deep in his brain with a thought.
This identification knowledge will only be sorted out and studied when he is free.
Looking at the small porcelain piece 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.
