My system is not decent

The hand-pressing cup is a unique utensil of the Yongle Dynasty. Because of its small firing volume and complicated craftsmanship, it has become an extremely rare and precious thing in the Chenghua period for more than ten years.

The flow of such precious porcelain abroad is generally believed to be due to official rewards and gifts, and the possibility of folk trafficking is very small.

Therefore, it is not unreasonable to regard this batch of porcelain as brought out by Zheng He.

Therefore, no matter where this kind of green material is produced, it has become a recognized fact that "Su Ma Li Qing" was introduced from Southeast Asia by Zheng He's voyage to the West.

Although many professionals believe that the blue and white cobalt material in the Yuan Dynasty is Su Ma Li Qing.

However, many research institutes later conducted research on the blue and white flowers of the Yuan Dynasty and the Yongxuan period of the Ming Dynasty, and found that the elements contained in the cobalt material were significantly different.

Of course, Chen Wenzhe didn't want to study academic issues, he just wanted to find out the most suitable ingredients for imitating Yongxuan blue and white, especially Su Mali green.

Because this kind of green material was gone by the middle and late Ming Dynasty.

This can be confirmed by the fact that the porcelain paintings after Chenghua have not been painted by Su Maliqing.

In other words, the Chenghua period still existed.

Since there is such a high-quality green material, the imitation effect must be achieved.

It is no wonder that he kept improving, because the Yongle and Xuande periods were the heyday of blue and white porcelain production.

During this period, there was a saying that "all materials are refined, blue and white are the most expensive".

Its achievements are praised as: "opening a miracle that has never been seen in a generation".

The blue-and-white porcelain made by Yongle and Xuande is close in production age and traditional craftsmanship, so there are many similarities, so they can only be distinguished through comparison.

The blue-and-white porcelain of the early Yongle official kiln was indistinguishable from the blue-and-white porcelain of the Hongwu official kiln when domestic materials were used.

After using the "Su Ma Li Qing" imported from abroad by Zheng He's voyages, this green material contains less manganese, so the fired blue and white flowers do not contain purple and red, but are pure "sapphire blue" color.

At the same time, due to the high iron content of this green material, there are often sunken black iron spots when fired.

The blue-and-white porcelain of the Yongle period is white and delicate, and the glaze is dark blue with black.

The glaze used is rich in divergence. After firing, the green material penetrates into the fetal bone, vivid and flexible, without the slightest pen marks, and some are like splashed ink on paper, with a strong painting effect.

Xuande blue and white porcelain bodies are made of hemp warehouse soil, which is white and delicate, and the raw material of blue and white porcelain is "Su Ma Li Qing".

This kind of green material has clear and bright hair color, stable color, scattered between the glaze of porcelain body, green and bright, vivid and vivid.

If the material is thicker, the ink will be muddy and solemn;

If the material is light, the color will be light and elegant.

More importantly, painted porcelain artists have absorbed the previous production experience and can master the performance of green materials and porcelain painting skills proficiently.

The porcelain decorations of this period are bold and unrestrained, with moderate thickness and clear layers.

"Tao Ya" contains: "Xuan kiln blue and white is an outstanding product in the heyday of Ming kiln. The selection of materials and samples, and the painting and inscription are all exquisite. They can be called porcelain, color and painting."

This feature is most representative of the Yongle blue and white seawater river cliff pattern tripod furnace in the Forbidden City.

Its main hair color characteristics are: the hair color is blue and bright, crystal and bright, like sapphires inlaid under the glaze, shining and shining, and showing a clear violet color;

There are obvious thick black crystal plaques or spots at the place of condensation, and the halo is serious.

This kind of color is precious, so the book "Ming and Qing Porcelain Appraisal" written by Mr. Geng Baochang uses the drawing of this tripod furnace as the shadow of the book, that is, the shadow of the picture under the inscription on the cover of the book.

If you want to imitate, you must imitate to the best, and this requires a lot of modern research results.

Modern society can be different from ancient times, transportation is underdeveloped.

Now as long as you want to find something, whether you can find it depends only on whether you have enough money.

Chen Wenzhe had long thought about Su Mali Qing material in the Yuan and Ming Dynasties.

Therefore, whether it is from Southeast Asia, Yin Lak, or even the green materials from the Persian region, Chen Wenzhe now has them in his hands.

He prepared this for the imitation of Yuan blue and white. Of course, if he can get enough macang soil or kaolin with the same effect, he will definitely want to imitate the porcelain of Yongxuan and Chenghua periods.

Now the green material in his hand must be qualified, but it is not so easy to imitate the effect.

For example, when imitating Yongxuan blue and white according to the ancient method, there are problems of halo and crystal spots.

This must be caused by the roughness of the green material. If it is exposed to strong light, it can be clearly seen that the crystallization spots are actually rust spots in the shape of particles in the green material. The reason is most likely due to the high iron content. .

The green material is rough, which is also very likely to be the cause of halo and crystallization spots.

Halo and crystalline spots are inherently a defect.

From the 80s to the mid-90s of the last century, Jingyu Ware Factory unearthed a large number of physical specimens in Ming Yongle and Xuande.

Among them, excessive halo or deep coloration are often one of the main reasons for being abandoned or eliminated, which also illustrates this point.

Therefore, it is really not easy to solve this problem.

However, it is not impossible, especially Chen Wenzhe who has a cheating device.

By studying some porcelains from the Yuan and Ming Dynasties and absorbing a lot of experience from the Yuan and Yongle Dynasties, he can skillfully and accurately grasp the characteristics of Su Ma Li Qing materials.

In this way, it is not too difficult to produce a pure blue cyan and achieve the best artistic appreciation effect.

Of course, it is not so easy to get the color of Chenghua Doucai.

The bright red is as bright as blood, the apricot yellow is reddish, and the water green, leaf green, and mountain green are all transparent...

These are some of the glaze colors used in Chenghua Doucai, and these glaze colors are reflected on the five imperial porcelain cups mentioned earlier.

It is definitely not easy to perfectly reproduce these glaze colors, but also to make the cup unique and elegant, and the decoration painting full and vivid.

In addition, in order to make bucket color porcelain more ancient, every small step is very important, such as the ratio of glaze water, the mineral preparation of color materials, and the weight of painting techniques.

For example, when drawing, it is necessary to use light outlines and heavy colors, and use a large number of traditional painting techniques such as dots, paints, flats, and extensions.

Only in this way can the painting style be concise and clean, and the whole picture has rich layers and aura.

All of these must be done well, and finally the drawn green body must be placed in a sagger and fired in a firewood kiln.

This is to restore the firing process of Ming and Qing imperial porcelain, because the firewood kiln is still significantly different from the modern process.

Of course, the firing cost is even more disparity.

After one kiln is fired, the consumption of bare pine wood is nearly 2000 catties, and the firing and cooling time is as long as 96 hours.

From material selection, mud refining, proportioning, casting, drawing, and firing, there are 12 major processes and more than 90 complicated detailed processes.

If there is a slight difference in any link, the fired works will be very different.

For example, only the trimming process includes 16 process details.

The thickness difference of each green body should be less than 0.2mm.

The weight difference should be less than 3 grams.
