My system is not decent

For example, in puddles and blisters, there are often old stains, smelly dry black, or yellow water spots.

This is an important feature of ancient porcelain, which is one of the rare things that Chen Wenzhe can say.

And the two old men also told Chen Wenzhe some secret techniques, such as water flow marks.

Water flow marks refer to the traces of water vapor volatilized by the surrounding objects in the closed space of ancient porcelain for hundreds of years, which has a sense of movement.

It is generally dark yellow and difficult to wash off.

This immersion in the air bubbles under the broken glaze forms the yellow water spot.

These things are all causal, and they certainly did not appear out of thin air.

In this way, the two old men talked about a kind of old-fashioned method, or the characteristics of ancient porcelain, and Chen Wenzhe also reciprocated, going a step further and talking about it in depth.

The two sides have come and gone, and it can be regarded as a pleasant talk.

The old-fashioned technology is different from the porcelain-making technology. If you want to make it perfect, you must know what an antique is.

Ancient, to what extent is it ancient, that is to say, you need to know what kind of characteristics the porcelain of each era has been handed down to the present.

Just like the yellow water spot mentioned earlier, what is its cause?What performance?

The cause of the yellow water spot is the same as the yellow water line, the difference is that the yellow water spot has no obvious dividing line, and it is not linear, but patchy.

The ancient porcelain with yellow water spots must have been destroyed in the early years, and the ancient porcelain was still in place for some reason, and it took several years before it came out again.

If the yellow water spot penetrates the porcelain bone, it is absolutely true, and it cannot be imitated in decades.

As for the yellow water line, many ancient porcelains have a horizontal yellow line inside and outside. The line is wider and the color is gradually thicker. There is a very eye-catching dividing line on one side of the yellow line. The closer to the dividing line, the thicker the yellow. .

This yellow water line has penetrated into the porcelain bone, even penetrated into the porcelain bone, and it will not fade for a hundred years. It has been soaked and washed repeatedly for ten years, but it does not work.

Note that there is only one line of demarcation for genuine products.

If you carefully push why there is a clear dividing line, you will naturally understand another series of tricks.

This feature is imitated now, the difference is that the dividing line is not clear, or multiple dividing lines are concentrated together.

In addition, the imitation characteristics made by imitators can be easily washed.

If it started to be forged 30 or [-] years ago, it is another matter, because it is difficult to wash after a long time, so another identification method needs to be found.

If there are multiple dividing lines, it must be false.

Because Chen Wenzhe made all pastel porcelain this time, he also specifically mentioned stylus yellow spots.

This term is dedicated to pastel multicolored glaze and painted identification.

The outline of the glaze painting is drawn with a stylus, the strokes are darker, and the lines are rougher, and the rougher areas are easy to be polluted. After a long time, there are many colors attached, mainly yellow.

In addition, if it has been immersed in yellow water for hundreds of years, the roughness will be more difficult to wash off, and the macular color will be heavier.

This is mainly an important basis for identifying whether it is handed down from ancient times, whether it is newly released, or whether it has been released for a long time.

Some people also wrote articles, calling it "black color purple light".

Speaking of this, Chen Wenzhe has said a lot, and it is also very deep, and even very thorough.

This kind of performance naturally made the two old people look at each other with admiration.

I already knew that Chen Wenzhe was powerful, but after seeing him, I would inadvertently underestimate Chen Wenzhe because he was too young.

Now they have put away that little thought and started to take it seriously.

Since Chen Wenzhe mentioned macula, they can't let Xiaonian underestimate it!

When it comes to various plaques on porcelain, the two old people sang together and directly talked about several plaques on ancient porcelain.

Like rust spots, blue and white rust spots and tire glaze rust spots.

Due to the weathering of ancient porcelain for a long time, there is a water-soluble phenomenon, so the rust spots become deeper and deeper with washing.

All natural blue and white materials will have rust spots, but the intensity is different.

When it comes to plaque, there are too many, such as old acid plaque, which is formed by long-term exposure to acidic organic matter.

The scars go deep into the fetal bone, the potholes are obvious, and the edges of the potholes have sharp angles.

However, the sour bite spots on the imitation products are rushed and fuzzy, and they are just superficial.

There are also sun spots, which are old yellow and reddish.

This is a spot formed by sunlight after more than ten years of long-term positioning in the wild.

Its spots can see through the porcelain surface, consistent inside and outside.

The fetus is broken and viewed, and the color of the fetus is also tanned into red and yellow spots.

Then there are water vapor spots, which are different from yellow water spots. They are formed by the accumulation of small amounts of water vapor for a long time and have been static for several years, which can be seen directly.

In addition to colored water spots, there are also colorless water spots. Because they are colorless, they are not easy to be felt. You have to look sideways, and there is a slight color difference from the surrounding area, which cannot be washed off.

Finally, there are obvious peeling spots, the glaze bubble is broken, and when rubbed, the broken remains gather together and are perceived by people.

Before and after rubbing, the glazed surface is observed under a magnifying glass, and there is a big change.

Due to the weathering of ancient porcelain, it cannot withstand the friction of human hands.

When it comes to friction, those who understand naturally know that ancient porcelain under what environment will have water flow marks, which are also friction marks.

If not, it is a fake, which is also an important evidence for identification as ancient porcelain, and it is easy to identify it with the naked eye.

Chen Wenzhe mentioned the Huangshui class, and Mr. Zhou talked about more plaques.

In the end, running water marks and so on were extended, which is not a kind, which made Chen Wenzhe feel a little slapped in the face.

And what happened next was completely beyond his expectations.

Could it be that these two old men came here to attack his arrogance?

This made Chen Wenzhe a little skeptical about life. He is also knowledgeable, but in terms of making old things, he is really not as good as others who have passed down hundreds of thousands of years.

Chen Wenzhe naturally didn't want to continue in such a situation.

So no matter what the two old men said next, he would answer a few words.

And when he talked about golden spots, that Mr. Li talked more, and they were all kinds of plaques. In the end, he even mentioned Mercury Qin.

This is another feature of ancient porcelain that Chen Wenzhe has never encountered before. If he came across this kind of porcelain by accident and copied it, he would definitely be beaten in the face.

The formation of Mercury Qin is similar to the formation of gold spots. The formation of gold spots is due to the extrusion of gold utensils.

Mercury Qin is ancient porcelain that has been in contact with mercury for a long time, and it will stick together, making it extremely difficult to clean.

So far, no imitators have been seen.

It's not that it cannot be imitated, if it is really impossible to imitate, Mr. Li will not mention it.

It's just that when this feature is unnecessary, no one will imitate it, because mercury is poisonous.

Besides, it is a bit troublesome to imitate, it is very similar to golden spots, it is not difficult to imitate, and even everyone knows how to imitate, but it is very troublesome to imitate.

It should be noted here that the concept of mercury on ancient porcelain is different from that on bronze.

The ancients used mercury for antisepsis.

In Qin Shihuang's mausoleum, a large amount of mercury was used, with copper as the mountain and mercury as the river.

Mercury Qin means that the ceramics are stained with metallic mercury.
