The method of identifying the authenticity of black gold glazed porcelain is as follows:

1.The shape of the observation vessel, the real black gold glazed porcelain are all small vessels, and the height of the bottle and the diameter of the plate and bowl are basically below 25 cm. Fake black gold glazed porcelain is not easy to grasp the scale, and the diameter will exceed 25 cm.

2.Observing the enamel, the enamel of the real black gold glazed porcelain is milky, which appears moist and thick, and the opening pattern is relatively clear, and the fetal glaze is tightly combined. The enamel of the fake black gold glazed porcelain is very bright, and there is no open piece pattern, and there is no joint of the fetal glaze.

Wujin glaze, also known as "iron black glaze", is a kind of precious monochrome glaze created and burned by Jingdezhen kiln in Jiangxi Province, because the raw material of the glaze is taken from the Wujin soil near Jingdezhen, so it is named. Wujin glazed porcelain began in the Chenghua period of the Ming Dynasty, matured and flourished in the Kangxi and Qianlong periods of the Qing Dynasty, the glaze of its utensils is smooth and translucent, the color is black like lacquer, deep like water, dignified and luxurious. Because Wujin glazed porcelain is different from blue and white or colored porcelain, the surface of the small flaws are extremely obvious, not easy to fire successfully, so the yield is very low, after the middle of the Qing Dynasty is rarely fired, so the amount of survival is very small.

Jingdezhen's traditional black gold glaze is made of a kind of locally produced black gold clay, after the rib years of the 20th century, Jingdezhen also used industrial waste or chemical raw materials to produce a very gorgeous black gold glaze, which is higher than the black and brightness of the historical black gold. Thank you.

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.

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).

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.

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.
