My system is not decent

In the late Qing Dynasty and the Republic of China, red-bodied porcelain was also valued by merchants, gamers and collectors.

But it cannot be sold at a high price. After all, the ultimate consumers are collectors and scholars, and the number of them is very small. This is also the reason today.

Since there are red tires, there must be tires of other colors, such as black tires.

All black-bodied porcelain is relatively ancient. In the late Northern Song Dynasty, there was less black soil, so it was mixed with white soil, and the color was gray.

Above the Northern Song Dynasty, there were many black fetuses, and they were black.

There is a kind of black tire Song Ding kiln, which is hard, black and thin.

Longquan in the Northern Song Dynasty was considered a gray fetus, not a black fetus.

There is a kind of black fetus, which has formed red silk for a long time, which is called "red silk black fetus". It is extremely rare, and it comes from Guan and Jun.

Now there are imitations, so the black fetus cannot be used as an isolated evidence, and it can be used as an independent reference for identification and can be used as a clue to help date.

In addition to these two types, there are pig liver tires, bronze tires, etc. Of course, the latter two are unique to some classic types.

For example, pig liver fetuses, this is the face with shrinkage glaze or shrinkage glaze scars, and the color of the fetuses is like pig liver color, darker and purple, which is the same as bronze fetuses. Pig liver is older than bronze fetuses. The higher the iron content, the darker the fetal bone.

Even if someone imitates it, it doesn't resemble it.

Bronze tires also have glaze shrinkage or glaze shrinkage scars, and the color of the fetus is bronze-like, reddish and yellowish, which is the same as pig liver fetuses, but the color is different due to different fetal qualities.

This is Guan and Ge kiln, special terms.

Other kiln mouths rarely appear.

The two fetal colors on it are related to the scarred faces of elder brothers and official kilns.

Scarred face is one of the unique phenomena of Guange Kiln. Due to the high temperature of the kiln and the separation of the make-up soil and the tire, a large glaze shrinkage scar is left on the porcelain. Most of them are oval, resembling human faces, so it is called shrinkage glaze scar Face.

Some people imitate it now, but it does not show the color of bronze or pig liver.

This scar color is not what it was when it came out of the kiln, but it has been transformed for thousands of years, so no one can imitate it at present.

Geguan scar face is quite different from the shrink glaze scar face of other kilns or varieties.

The edges of the scars on Brother Guan's scarred face are particularly thick and easy to distinguish.

Chen Wenzhe listened very carefully. Through the words of the two old men, he was able to confirm each other with what he had learned from his inheritance.

After all, these all belong to the category of porcelain making. It turned out that Chen Wenzhe must have learned it, but when he learned the basics of porcelain making, because the knowledge involved was too wide, he gave up some knowledge that was not needed and did not delve into it.

It's different now, with the rapid improvement of his various skills, by analogy, as long as he has a little contact, he will know what to do.

Since the two old men were sincere, they talked about some ancient porcelain production techniques, especially for some ancient porcelain features that are difficult to imitate, and analyzed them in simple terms, which made Chen Wenzhe gain a lot.

That way, he doesn't mind talking about some real craft.

Just now they mentioned red tires, which involves ruby ​​red.

Regarding knowledge in this area, Chen Wenzhe's attainments are not weak. Ruby red glaze cannot be said for sure, but red glaze can.

"Then let me talk about the glaze color. I wonder if your elders have seen the phenomenon of red clouds?"

The phenomenon in porcelain like Hongyun is still very beautiful.

The red cloud here refers to the red spots formed due to color difference in the red glaze.

This kind of erythema is like the clouds in June, with various shapes and shapes, and it is more obvious under strong light sources.

This does not refer to the phenomenon of flying copper, but specifically refers to the color difference characteristics of the combination and repulsion of substances in the glaze.

The colors vary in shades and are not obvious.

Tang Hong and Lang Hong are similar phenomena.

So far, no copper-red glazed porcelain that can imitate one or two percent of the flavor of ancient porcelain has been seen. From this, it can be seen that copper-red glazed porcelain is not easy to imitate.

Special attention is paid to the fact that the red cloud has a sense of flakes, and the red cirrus cloud has a sense of lines.

Since there are red clouds, there must be blue clouds, which are the same as red clouds, which are blue patches.

In addition, silver and gold dots are often found under the blue glaze, which may be related to the material of the glaze, which is also flake.

Others include rose purple, which is a kind of hair color on the glaze of Jun kiln. It is actually composed of red cirrus clouds, living flow patterns, multicolored bubbles, purple dots, blue dots, green dots, and gold dots.

It looks like rose-like purple on the whole, but if you study its parts carefully, you can see different colors.

These phenomena have not been imitated so far. According to records, the above-mentioned red glazed soil was extinct in the middle of the Ming Dynasty.

The frequency of rose purple is higher than that of begonia red, and it is as difficult to burn as Jihong, Tanghong and Langhong in copper red glaze.

The last is Begonia Red, which is similar to Rose Purple, but the overall color is brighter, with fewer purple spots, blue spots, and green spots. There are more red cirrus clouds forming the main color.

Again, whether it is Jun kiln, Ge kiln, official kiln, or copper-red glazed porcelain, it is difficult to fire.

It is a very rare opportunity to be able to exchange information in this area, any knowledge point.

After all, it involves the five famous kilns of the Song Dynasty, and the knowledge in this area should be considered the highest in the antique industry.

The more the two sides talked, the more in-depth and serious they became.

As long as both sides can still feel that they have gained something, they will naturally not stop.

Just now Chen Wenzhe mentioned ornamentation and glaze color.

The two old men can only reciprocate. Chen Wenzhe mentioned various glaze colors earlier, and also emphasized some various color points.

There are many such phenomena in ancient porcelain.

Such as blue dot, azure glaze, tanglanhuajun, songjun, duck egg green ground glaze, etc., most of them can find blue mineral spots in the glaze.

All glazed surfaces with blue spots will change color, and the color will turn light when it is protected from light for a long time, and the color will become darker soon after being exposed to sunlight.

In addition, the viewing angle is different and the color is different, and the light source radiation is different and the color is different.

According to the predecessors, it contains agate juice.

It is worth noting that before the Ming Dynasty, as well as some blue and white flowers from the third Qing Dynasty, they will also change color, and the material of Sumaliqing is the most obvious.

There are also green spots, which can appear in the nails of Ru Kiln. The name is diabase. It is a mineral body that is resistant to high temperature and acid and is bright green.

Only with it can the support nail be as small as a sesame seed.

This is really the first time Chen Wenzhe knows that he has learned Zhiding Yaki specially, but he really didn't know that the sesame burning in Zhiding Yaki is actually related to diabase.

It can be said that paying attention everywhere is learning!

Without this exchange, where would he learn these knowledge?

Even Chen Wenzhe didn't know these things before, so can modern people imitate them?

Ru kiln imitation has always been difficult.

As for the green dot, many of the current counterfeit producers don’t know the effect of the green dot, so the studs of the counterfeit are too thick and lose their charm.

It is speculated that the green dot is not purely studied by physical methods. The ancients used Taoist alchemy and chemical methods.

Then there are gold and silver dots, and silver dots are silver-white objects that appear in the glaze of the Jun kiln system of ancient porcelain.

It is not common, about one-tenth of the ratio, and it is displayed only when the pyrotechnics are higher.

Gold dots, the golden objects appearing in the glaze of Jun kiln series of ancient porcelain.

The probability of appearance is higher than that of silver dots, accounting for about one-fifth of the ratio, and it does not require excessive temperature.
