My system is not decent

People like Wu San, who are in the rivers and lakes, can always play like a fish in water. No matter whether they have a bit of cultural background, they should not be underestimated. At least they can speak very well.

Wu San started the conversation, and the rest was the performance time of the two old men.

"Do you know how Flint Red is formed?" Elder Zhou said indifferently.

As long as you play antiques, you should know Flint Red. If you don't know it, it is pure leek.

Several people here understand it, even Wu San understands it, but he doesn't understand much.

As for Chen Wenzhe, he really hasn't studied Flint Red specifically, but he knows how to make qualified Flint Red, and that's enough.

Of course, Jingzhen is a professional. As long as it is related to porcelain, they have studied it very deeply.

For example, this seemingly ordinary flint red, flint red refers to the exposed body of ancient porcelain, which shows red, and there are also yellow red, purple red, gray red and so on.

Individuals with serious flint red can also climb one or two millimeters from the tire to the glazed surface.

Many people think that this phenomenon must only be seen in antiques.

In other words, the appearance of this phenomenon is a phenomenon of aging.

But the fact is not entirely the case, because some porcelains are there when they come out of the kiln, commonly known as "flint red from the kiln".

It gradually formed after leaving the kiln, which is called "acquired flint red".

The ancient kiln was made of flint red, and its appearance at that time can only be inferred from modern porcelain.

After several years of experience, it is beyond recognition, because a series of other ancient porcelains have interfered with it.

Therefore, looking for the characteristics of ancient porcelain, we will mainly produce flint red in the future.

Generally, it will appear in the recesses of the utensils, on the nails, on the seams, on the tendon spit lines, on the fiery dirt, and there will be a metallic luster on the surface, which is caused by millennium oxidation and fiery exhalation.

If the time does not exceed several decades, it will not produce metallic light.

The older the age, the stronger the metallic light.

Of course, not all porcelain will form flint red, because the main component of flint red is iron oxide.

If the iron content of the porcelain itself is extremely low, it is not easy to find flint red, and some have to use a hundred times magnifying glass.

If you can't find any flint red, it can be judged as new porcelain.

If the flint red metallic luster behind the concave part of the porcelain is not obvious, it needs to be judged comprehensively in combination with other ancient porcelain features.

He had known for a long time that the two old men were masters, and Chen Wenzhe was not surprised that they knew Flint Red.

And the large plate he made was kiln flint red, but he made it old again later, such as metallic luster and so on.

In fact, it is definitely not Flint Red that he is the most old-fashioned, because this is too obvious, and too many people can do it.

For example, the obvious features of cow hair pattern and flint red will certainly not be difficult for the masters at Jingzhen.

Therefore, Chen Wenzhe just listened to their flattery without saying a word. If he had to be serious, maybe the two old men would laugh at him.

However, these two old men were not blind. Although they didn't look carefully, they also saw some bubble pits on the surface of the porcelain.

This is the real strength, and this is also some unexpected gains that Chen Wenzhe obtained through the secret color porcelain.

After being collapsed for a while, Elder Zhou looked at Chen Wenzhe again: "Xiao Chen, is the foam on your porcelain?"

Hearing this, Chen Wenzhe laughed. The old man really could bear it, and he only mentioned it now.

"The treatment is great. After the bubble is broken, it can be soaked in water to form the current appearance. It's not easy!"

Lao Li is also a little bit emotional, after all, the porcelain in front of him is very beautiful, which requires high processing of the bubbles.

"Really!" Chen Wenzhe was still very interested in Jingzhen's old-fashioned methods.

The main reason is that he has seen too few modern high-quality imitation porcelains, because as long as they are high-quality imitations from Jingzhen, they usually go to the top auction houses, and finally flow into the treasury of some big private collectors. How can he see them? arrive?

Only by seeing a lot can one know a lot. He has never seen a few high-quality antique porcelains, so naturally he doesn't know the technology of Jingzhen.

Just like the living flow pattern mentioned earlier, he has never even seen it before, so how could he imitate it?

These two have already shown their hands several times, and it's time for Chen Wenzhe to show off, otherwise these two old people will really look down upon them.

After meeting two masters, it seemed that they also wanted to communicate, and Chen Wenzhe naturally would not refuse.

After all, he really has a deep understanding of the bubbles in the glaze layer of porcelain, as well as broken bubbles, and even all the subsequent changes.

Bubble breaking refers to the bubbles on the glaze surface, which are ruptured due to weathering, silica gelation, cleaning and friction.

Generally, bubbles are seen in the upper layer of the glaze, and when the damage to the glaze is too serious, the bubbles in the middle and lower layers are seen.

Song porcelain, there will be this phenomenon, it is difficult to imitate.

If you find smelly dry black or yellow water spots in the broken bubble, it can be judged as ancient porcelain.

There is also a feature called ice cracking and bursting bubbles, which is magical and wonderful. The top of the bubbles is radioactive ice cracking, which is more difficult to imitate, and few people can imitate it.

This is also an important reason why Ru kiln and ice cracked porcelain are difficult to imitate.

As for the smelly dry black and yellow water spots, they are also special signs on ancient porcelain!

Smelly dry black refers to the ancient porcelain stained by corrupt organic matter, most of which are manifested in plain tires and broken bubbles.

After long-term blistering, it will soften, swell, and be washed off.

Those who make fakes are made of river pond sludge.

There are differences under the magnifying glass: smelly dry black, amorphous, river pond mud, with soil particles.

In particular, the stinky dry black drilled in the micro-broken bubbles takes hundreds of years to form, and generally appears on ancient porcelain before the Ming Dynasty.

There are also porcelains from the third dynasties of the Qing Dynasty, but they are rare, and it is difficult to find them with a magnifying glass.

In the late Qing Dynasty, only a little bit can be found on low-temperature porcelain that is underfired.

As for yellow spots, or gold spots, this refers to the golden traces left behind by gold wares pressing ancient porcelain all the year round and penetrating into glaze bubbles or rough hairs.

This kind of spot cannot be imitated. The older it is, the deeper it penetrates, and it is not easy to wash off.

Of course, yellow water spots are very easy to make. As the name suggests, the yellow marks left by water soaking in the broken air bubbles are yellow water spots, which are easy to imitate.

But there is another kind of soaked yellow paste that is more difficult to imitate. This phenomenon generally appears on Songguan and Geci.

Soak in clear water for a day, and the clear water will have a yellowish, turbid feeling, such as Huangyuguan, Huangyuge, Liaohuangyu, and more conspicuous.

This is suspected to be formed after the iron-chloride compound in the gold wire and yellow glaze was hydrolyzed. Until now, Chen Wenzhe has never heard of it, let alone seen any imitation.

For communication, there must be exchanges. Chen Wenzhe talked about some methods for breaking bubbles.

Bubble hole means that after the large bubble on the glaze surface breaks, a large hole appears in the glaze, with a small mouth and a large inside.

The inner shape is different from the brown eye, and the broken eye is a spherical hole.

And as long as the blisters are broken, dust will definitely accumulate in these blisters after a long time.

Here the difference appears, because the external environment is different, the substances contained in the blisters are different, which forms various blisters.
