How to identify the black gold glazed porcelain of the Ming Dynasty, and which period this black gol

The identification of Wujin glazed porcelain in the Ming Dynasty can be started from the following aspects:

1.Observe whether the porcelain soil has been manually washed. Generally speaking, the fetal soil of Ming Dynasty porcelain will be manually washed, and the firing fetal material will appear particularly clean. Due to the precipitation of time, the fetal material of these old porcelains appears to be both powdery and fine-grained.

2.Check the thickness of the carcass. The thickness of the porcelain carcass of each dynasty is not the same, and the thickness of the porcelain carcass of each dynasty is grasped well, and the basic consistency is likely to be genuine.

3.Observe whether the density of the carcass is too large or too loose. Ancient porcelain will be artificially adjusted when making mud, and the fetal density of the tire burned by artificial and clay billet is suitable, and there is no excessive density or too loose phenomenon.

On the other hand, in modern imitation porcelain, the mud used to make tires is refined by a mud refining machine, and the density of the fired tires is too large, and it feels too heavy in your hands. Of course, counterfeit products are also made by grouting tires, and their density is too loose, and they feel too light in your hand.

4.Pay attention to whether the surface of the porcelain is painted with modern chemical pigments, and if it looks unnatural, the color is too bright, and the color is too uniform, you need to judge carefully.

5.Good black gold glazed porcelain glaze moisturizing, treasure light can be seen. Observe the gloss reflected on the surface of the porcelain, if the reflected gloss is harsh, it may be an artificial chemical glaze. The surface of real ugin glazed porcelain is shiny and lubricating without glaring.

6.For porcelain without slurry, the false slurry under the polishing process generally floats on the surface of the utensil, which is unnatural.

7.If a piece of porcelain looks like it has been painted, it is most likely a newly made imitation. The cladding on the real ancient porcelain is like a glass light and looks very soft.

Ugin glaze is a type of monochrome glaze. Compared with other monochrome glazed porcelain, the black gold glazed porcelain is deep and watery, dignified and luxurious, with its own momentum, and it is also more precious. Wujin glaze began in the Chenghua period of the Ming Dynasty and is represented by the works of the Kangxi Dynasty of the Qing Dynasty.

It is a kind of pure black glaze that is smooth and translucent, black as lacquer and fired by Jingdezhen porcelain workers using the black gold clay glaze with iron content. After the 20th century, Jingdezhen also used industrial waste or chemical raw materials to produce a very bright black gold glaze, which was higher than the black and brightness of the historical black gold. The main feature of the black gold glaze is that it is black and bright, with a sense of solemnity.

The rest is redundant.

The black gold glaze is first of all black, jet black and bright; followed by gold, microscopic Venus is brilliant; Finally, the glaze is smoother than any porcelain. Anything that paints, bronzes, or inlays gold on black-glazed porcelain is not black gold glaze.

This piece is supposed to be a black gold glaze made in the late Qing Dynasty. But the bottom foot flint red bottom foot, the traces of imitation are obvious, because if it is a genuine flint red bottom foot, then he is a black gold glazed porcelain made in the Kangxi year.

Ugin glaze:

Wujin glazed porcelain began in the Chenghua period of the Ming Dynasty in China and is represented by the works of the Kangxi Dynasty of the Qing Dynasty. Later, Jingdezhen's Wujin glazed porcelain made from industrial waste and chemical raw materials was improved compared with the Wujin glazed porcelain of previous dynasties.

It is not easy to distinguish between black glazed porcelain and black glazed porcelain with the naked eye, but it is easy to distinguish between the enlarged glaze under the electronic magnification closed-state travel mirror.

The glazed surface of the black gold glaze is distributed with golden yellow dots, like a slap on the satellite to the mountain, winding, uneven.

The glaze of the black glaze is like a piece of black paper under the magnifying glass, which is very flat.

Based on the reference articles provided, it can be judged that this item is a black gold glazed porcelain.

1. The main judgment is that the glaze is dark black and dark yellow, which can be used together with gold painting techniques.

2. There are two kinds of materials: pure black and black ground color: pure black is one color; Black ground color is painted on black ground, with yellow, green and purple three colors.

3. Use the glaze of Wujin clay with large iron content to burn a pure black glaze with translucent luster and black color.

4. The difference between Wujin glaze and the general is that in addition to iron, there are also elements such as manganese and cobalt.

5. Here we use a magnifying glass to compare the difference between the black gold glaze and the black porcelain building lamp: under the computer electronic magnifying glass, the magnification is 75 times, and the high-quality black gold glaze glaze (black gold glazed elephant ear bottle).

First, there must be a jade texture. The porcelain of the Song Dynasty pursued the effect of jade, and the jade texture was the top quality, especially as the porcelain made by the court, and it was necessary to burn the jade texture. Therefore, to get started with a piece of porcelain (whether it is white or color glaze), the first thing to see is whether there is a jade texture?

The genuine product should be glazed and moist, full of agility, just like white jade. Imitations are not easy to grasp because of the raw materials of the tire glaze and the firing temperature, so it is difficult to burn the texture of jade. Generally, the aura is sluggish, the glaze is pale, and there is no jade texture at all.

Individual can burn out the texture of jade, but the common color is new, and there is a sense of fire.

Second, the glaze is as white as ivory. Five generations later, the kiln ware was no longer glazed with soil.

The glaze of the white glaze is white and yellow, so the color of the glaze is the so-called "ivory white" color. A few poor quality glazes are gray and yellowish in white. The glaze surface of Baiding is translucent, because the glaze is thinner, so the tire color can be faintly seen in the thin place.

At the fold of the waist, you can see that the glaze is light yellow-green. The bubbles at the glaze are sparse and transparent, and the size is different. This is also a point to pay attention to when discerning.

Because the imitation cannot grasp the specific firing atmosphere of the kiln, it is difficult to fire the glaze color of "ivory white". The glaze color is often either white or yellowish, and it is difficult to see light yellow-green at the waist of the utensil.

Third, to see the "bamboo silk brush marks". In the tire making process of the kiln, when the tire is half dry, there is a bamboo wire brush to rotate this process, so there are some "bamboo wire brush marks" on the tread. Because the glaze is thinner, after firing, the brush marks left by the bamboo wire tire repair can be faintly seen through the glaze in the thin glaze.

This is one of the basic characteristics of Dingyao porcelain, and special attention must be paid to when appraising. This kind of "bamboo silk brush marks" is often not seen in imitations. Some have done it, but it is done bluntly and clumsily, and it is not natural enough, so it can be identified according to this.

Fourth, the glaze is common "wax tear stains". This "tear stain" is caused by uneven glazing and sagging of glaze water when firing. The lower part of the vertical glaze resembles a waxy tear-like protrusion, and the lower part of the spherical surface is light water green.

This "tear stain" only appears on the outside of the bowl. Whether there are "tear stains" has also become a basic feature of whether to determine whether it is Beiding. Of course, not every kiln porcelain has "tear stains", but it is easier to confirm that there are "tear stains" than those without "tear stains".

It is difficult to make this kind of "tear stain" with ordinary imitations.

If you don't know how to consult.

The general process of appraising antiques is as follows:

One look at the styling. Ancient porcelain is not the same as the dynasty has different shapes, and sometimes you can judge from the shape of the porcelain in what era.

Second, look at the fetal quality. Different ages of porcelain are different in the quality of the fetus.

Three look at the ornamentation. It is not the same as the times, and the ornaments are also distinctive.

Fourth, look at the style of Hu to hide. Some ancient porcelain has to be printed at the bottom of the style, each dynasty has a different way of writing, from the style can also identify an ancient porcelain age and value.

Fifth, look at the process. Sixth, look at the feeler's staring.

This requires the appraiser to have a wealth of historical knowledge and practical appraisal skills, and you can take things to Saga Appraisal to have a look, which are all some of the top experts and are very authoritative internationally. If you can't find it, you can search for "Family Collection", and the first one is.

The difference between black gold glazed porcelain and black glazed porcelain is not easy to distinguish with the naked eye, but under the electronic magnifying glass, it is easy to distinguish between the magnified glaze. The glazed surface of the black gold glaze is distributed with golden yellow dots, like the slap on the satellite to the mountains, meandering, uneven. The glaze of the black glaze, like a piece of black paper under a magnifying glass, is very flat.

The Song, Yuan, and Ming and Qing dynasties of Wujin glaze Wang dig this area trapped Xun Bei 1, Song, Yuan, Ming and Qing dynasty porcelain modeling differences.

The Song Dynasty was more simple in shape, mainly imitating bronze shapes, and there were many small pieces, but the corners of the utensils, the edge of the mouth, and the bottom foot were very particular about decoration. For example, the utensils of Ru, Guan, Ge, Ding, and Jun are all very standardized.

The repair of the Yuan Dynasty utensils is not very particular, especially the bottom foot of the utensils is very rough, and the large pieces often have warped edges, angles, concave cores, convex bottoms and other deformations.

The shape of Yongle in the Ming Dynasty is simple and beautiful, especially the hand cups, plates, bowls, etc. are made more finely. The shape of Xuande utensils is rich, the production is exquisite, the shape of the Chenghua ware is small and light, and the workmanship is excellent, so that the imitators are beyond reach. Hongzhi and Zhengde are dignified and beautiful.

The shape of the vessel after Jiajing and Wanli is both heavy and simple and light and gorgeous, but the production is relatively rough. Sanzhou.

The three dynasties of Kang, Yong and Qian in the Qing Dynasty were the peak period of Chinese porcelain. Kangxi's utensils are thick and clumsy. There are many imitation Ming Yongle, Xuande and Chenghua utensils. Yongzheng ware type is famous for its exquisite lines.

2. The difference between the bottom foot of the porcelain of the Song, Yuan, Ming and Qing dynasties.

The bottom of the Song Dynasty utensils is made in a fine and regular manner, there are foot wrapping and burning, glazed all over, and there are also no glazes, only brushing a layer of tire glaze water. The exposed part of the official kiln is dark gray or gray-brown, commonly known as "iron foot", and the cross section of the nail is gray-brown. The cross-section of the Ru utensil nail is pinkish-white.

Most of the Yuan Dynasty utensils are exposed and coarse, with flint red. The bottom of the bowl is made of chicken heart, and the inside is pointed and the outside is round, which is a characteristic of the entire Yuan Dynasty.
