Chapter 1562 Seven Color Effects
The content of elements in the raw materials is different, and the color of blue and white porcelain after firing is also different.

Iron oxide is black in reducing flame, and manganese oxide is purple in reducing flame.

Therefore, blue and white flowers fired from "Sumaliqing" materials with high iron content are prone to black spots in the rich blue, which is the main feature of imported green materials.

Now that we know the characteristics of Su Maliqing, can we use modern methods to produce the same effect?
Certainly, for example, Yuan blue and white, do modern people have high imitations?
The high imitation here is the kind of high imitation that cannot be identified even if it is appraised by the top appraisers of the auction house.

There must be, but this kind of high imitation is not accessible to ordinary people, and it will not let many people know about it.

As for those so-called masters in the market who shout that he can make a high imitation, they are all liars.

It is absolutely impossible for a real master to be known easily, nor can it be publicized.

Isn't it good for people to make a fortune in silence?Why spread the word?

Those who promote are all liars who can't find the people who have been taken advantage of.

This is like those famous doctors advertised on the Internet, how famous and powerful each one is.

But, have you ever thought about it, a real famous doctor, does he have time to chatter online?
People who come to see him every day travel two miles away. How can he have the spare time to do publicity on the Internet?There is no need for that.

The same is true for high imitation, and there is this highest level of high imitation on the market now, but it cannot escape scientific identification.

This is also the reason why some appraisers desperately belittle scientific means of appraisal.

All of them use scientific means, who still uses traditional appraisers?
In fact, the best way to identify antiques is thermoluminescence and aging identification.

The composition identification is unreliable, needless to say, this is the best place to forge ancient porcelain.

Traces of natural aging are the most difficult to imitate.

The second is thermoluminescence. This dating method is completely different from the identification of carbon fourteen.

Thermoluminescence effect, sometimes translated as thermoluminescence, thermoluminescence, is a cold luminescence phenomenon.

When some crystals, such as minerals, are heated, electromagnetic radiation, or other ionizing radiation, that was originally absorbed and stored in lattice defects is released in the form of photons.

This phenomenon should not be confused with black body radiation (also known as thermoluminescence).

In archaeological research, it can be used to determine the age of ancient cultural relics.

Because cultural relics are irradiated by natural radioactive elements uranium, thorium and potassium in the surrounding environment during the burial process.

The longer the burial time, the more electrons and holes are generated in the cultural relic, so the stronger the thermoluminescence.

Therefore, using thermoluminescent technology, it can also be made into a radiation dosimeter.

Chen Wenzhe understood this technique, naturally, to understand thermoluminescence dating.

Thermoluminescence dating refers to the technique of dating by using the thermoluminescence phenomenon of insulating crystalline solids.

Suitable for pottery, and other fired clay samples.

The range of dating can reach tens of thousands of years.

Pottery is made of clay, which generally contains traces of radioactive substances such as uranium, thorium, and potassium.

They are subjected to all kinds of radiation all the time.

When pottery is fired, the high temperature releases the energy previously stored in the crystalline solid.

Since then, the energy has been re-accumulated, increasing over time.

The stronger the radioactivity and the longer the age, the greater the amount of thermoluminescence.

That is, the amount of thermoluminescence is proportional to the total radioactive dose received.

As long as the content of uranium, thorium and potassium in the pottery is measured, the radiation intensity and cosmic ray intensity in the surrounding soil are determined, and the annual dose of natural radiation is determined, the age of pottery firing can be calculated.

Therefore, as long as you understand thermoluminescence, you will know the method of using radiation. It is almost impossible to avoid thermoluminescence identification just like avoiding the carbon fourteen identification method, because it is too difficult to control.

Of course, Chen Wenzhe is just imitating now, not imitating antiques, and he doesn't know how to make old ones.

Naturally, he is not afraid of other people's identification, so he only wants the porcelain to show the best effect.

In this way, if the craftsmanship of the ancients is perfectly reproduced, it is not the best choice.

Not to mention ancient crafts, but ancient raw materials, it is difficult for him to reproduce them perfectly.

Even if he has a cheating device and knows the origins of various raw materials used in ancient times, it will be difficult for him to completely restore the ancient environment.

Therefore, the best way to perfectly present the beauty of ancient porcelain is to use modern chemical green materials to mix colors.

And this requires an understanding of the color of porcelain.

Now Chen Wenzhe just wants to study blue and white porcelain, so he must understand the color development of blue and white porcelain in the past dynasties.

In terms of function, color development is the most beneficial tool for porcelain dating.

In terms of aesthetics, it records the history of royal aesthetic evolution for hundreds of years.

Even the personality of the emperor is reflected in it.

For example, he knows that the top and most classic ones should have seven color rendering effects.

Blue and white hair color, the most famous one should be azure and other misty rain.

Anyone with eyes knows that the color of blue and white porcelain has nothing to do with azure.

However, Ru porcelain has indeed made azure color.

The color of blue-and-white porcelain depends entirely on its raw material, cobalt oxide, and its color performance after high-temperature firing.

The cobalt materials with different components also have their own flavors when fired.

Sumaliqing is a kind of blue and white, because of its special nature, the blue and white made by using it is very distinctive.

Of course, any kind of material can be used by anyone.

Used well, it performs well.

If it doesn't work well, it's just a pitch-black mess.

Just like Su Ma Li Qing, if used well, the color will be deep green, thick and deep, and bright in color, as bright as sapphire.

Even Emperor Yongle couldn't put down such porcelain.

But there is no pure gold, and Su Maliqing's beauty also has flaws.

Still because of its special nature, the porcelain fired from Sumaliqing is often accompanied by the coloring.

In addition, there are dark brown rust spots, now known as tin spots.

And this kind of defect is also called the most important symbolic aesthetics of Su Maliqing.

As a unique green material in the Yongxuan period of the Ming Dynasty, Su Ma Liqing created another style of blue and white porcelain.

It is naturally indispensable in the famous blue and white works of that dynasty.

Mingyongle's hand-pressed cups with dense lines and tin spots, and the chicken heart cups are his proud works.

In the Yongle and Xuande periods of the Yuan Dynasty and the early Ming Dynasty, Sumaliqing material was mainly used.

The ingredients of Soviet materials are low manganese and high iron.

Manganese is easy to cause purple and reddish hair color, and low manganese is not easy to appear purple and red, so the hair color is bright and the sapphire blue is bright.

The iron element turns black after firing, and the high iron content makes the blue and white flowers appear black and purple spots after firing.

However, if these scattered black spots are used well, they can bring strange effects to blue and white.

In the hands of masters, such defects are a bit like the heavy ink smudges in ink and wash paintings, and the colors are suitable in shades, reflecting the artistic effect of ink and wash paintings.
