How to identify the new and old porcelain, nine tips for the identification of old porcelain

There are many differences between the old and the new porcelain.

1. The shape and charm of the instrument are different. Imitations can only imitate the likeness, but not the likeness.

2. The raw materials of the fetal soil are different. The raw materials used to make porcelain in ancient times are different from those used in modern times.

3. The production process of tires is different. There is a difference between the tire made by manually crushing porcelain clay and the tire made by crushing porcelain clay by ball mill; There is also a difference between the porcelain tire produced by artificial mud and mud and mud training machine.

4. The enamel formula is different.

5. The glaze is different. There is a difference between the glaze produced by long-term oxidation and weathering in the air and the glaze of freshly fired porcelain.

6. Different colors. Ancient porcelain paintings used mineral color, and modern porcelain painting mostly uses chemical color.

7. The characteristics of painting are different. Each era has its own aesthetics, which will inevitably be reflected in the paintings of porcelain.

8. The traces of use are different. The traces of use produced by the years are not the same as those made by the characters.

Two methods: 1. Listen to the sound The old porcelain has gone through the years The sound is crisp and long when struck, and the sound of the new porcelain is sharp and short.

2. Look at the watch Side light to observe whether there are micro scratches or other traces of use on the surface of the porcelain Generally, old porcelain will definitely leave traces on the surface after time, and new porcelain generally has no or very little glossy surface.

It is difficult to explain this sentence or two, and the most basic way to distinguish it is from his vessel shape ornament and tire glaze, as well as his mouth and feet. Hope it helps.

Nine tips for the identification of old porcelain: 1. The sense of lightness and heaviness is constantly self-perceived, realized, compared, and corrected by touching the porcelain, and finding the sense of lightness and heaviness that suits you to distinguish between the old and the new. The system and system that form its own sense of lightness and heaviness play an important role in the dating of unknown porcelain and the distinction between kiln mouth, quality, taste, old and new, authentic and fake, imitation and fake.

1. Glaze feel identification method. All new porcelain, no matter how old, feels astringent and sticky, similar to the feeling of touching the glass with your hands, and if you rub the glaze quickly with your hands, it will even make a sharp and harsh sound;

2. Use a magnifying glass of more than 100 times to see the bubbles in the glaze, because the new porcelain is directly fired with electricity or natural gas, the temperature rises quickly, and the temperature is constant and lasting, and the temperature fluctuates little, so the bubbles in the glaze are as small and dense as prickly heat, and there is no sign of aging and decay;

1. Look at the firelight: The firelight of the new porcelain is also known as the "thief light", which looks flashy and dazzling; And the light of the old porcelain is the warm light that comes out from the inside of the porcelain, which is pleasing to the eye. 2. Look at the painter:

The paintings on the new porcelain are mostly prints and appliqués, while the old porcelain is mostly painted by hand. 3. Look at cracks: the surface of new porcelain is smooth and generally has no cracks, while old porcelain has different degrees of cracks.

How to distinguish between old and new porcelain

Porcelain is made of porcelain stone, kaolin, quartz, mullite, etc., and is covered with a glass glaze or painted surface. The forming of porcelain is to be fired at high temperature (about 1280 1400) in the kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to the difference in temperature, which is a treasure of Chinese civilization. China is the homeland of porcelain, which is an important creation of the ancient working people.

In China, the word "porcelain" was first used in Xu Shen's Shuowen Jie Zi. The word "porcelain" referred to "pottery" before the Han Dynasty, and Xu Shen's "Shuowen Jie Zi" explained that "porcelain" was "pottery, from the watts." "The Book of Sui: The Biography of He Chou" recorded that "the craftsman did not take the clear intention, and the thick was made of green porcelain."

The green porcelain of that time should have included some of the glazed glass products that are called celadon today. Cixian Museum has a collection, but at that time it was not called "celadon", but "green porcelain".

In addition to this, you can also see the clam light of porcelain. Some old porcelain has been formed in a variety of colors, such porcelain is at least 60 years old, while new porcelain does not have such light. Or you can also listen to the sound, as long as there are no cracks in the old porcelain, the sound of the knocking is as crisp and pleasant as the sound of a bell, while the sound of the new porcelain is more muddy.

The glaze of the old porcelain is generally matte, the glaze is not very bright, there are traces of friction at the bottom of the porcelain, often showing dark red or yellowish, the old porcelain generally has cracks due to the use of time for a long time, and the glaze of the new porcelain is very bright, the bottom of the porcelain is very new, there is no trace of friction, and the bottom is generally white, and the new porcelain generally has few cracks due to the lack of use.

Porcelain is a kind of object composed of porcelain stone, kaolin, quartz stone, mullite, etc., and the surface is glazed or painted. The porcelain is formed by firing at a high temperature (about 1280-1400) in a kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to the different temperatures.

It can be identified from the color, glaze, soil quality, painting workmanship, and craftsmanship.

1. Look at the color of porcelain: no matter what kind of old porcelain it is, whether it is blue and white or enamel, etc., after the accumulation of time and the passage of time, its color will appear relatively heavy, because its material is rich in minerals and is easy to gather and disperse.

Therefore, the general old porcelain looks easy to spots, and it is more fetal, and there are very rich shade changes, just do it. This is especially the imported blue and white material from the Yuan and Ming dynasties, with dark blue with purple and black brown spots.

2. Look at the glaze of porcelain: the glaze is the light emitted, and the glaze of old porcelain will show a soft light under the illumination of the light, because the porcelain will leave grease for a long time, and the grease will refract a light similar to a little pale green.

The surface of the new porcelain is very dry, and there is no heavy grease feeling, and the pale green color that cannot be seen clearly or at all under the light may be observed, and a closer look may also observe small cracks.

3. Look at the porcelain soil: The old porcelain fired in the soil used in the past will have small pittings, and the irregular distribution can be seen when the magnifying glass shines on the past.

Nowadays, the new porcelain will use modern techniques to make the old, but in any case, there are still many differences between the soil used and the soil of the past. Therefore, when the magnifying glass shines through and you can't see the fine pitting on the porcelain, then you should pay attention.

4. Look at the porcelain painter: The painter mainly pays attention to the image of the characters in the porcelain and whether it is vivid. The old porcelain is all hand-carved figures, and basically there will be no repetition of the picture, and the painter will pay more attention to the drawing method and the outline of the line.

However, because the new porcelain is machined, the picture will be repeated, and even there will be ink leakage, and the painted figures are also very dull.

5. Look at the porcelain process: many old porcelain are hand-drawn embryos, and the upper body, lower body and bottom are made separately, so there are many joint gaps in the old porcelain that are difficult to see with the naked eye. Although the new porcelain will also be imitated, it can be distinguished by paying attention to whether the traces of the tire are even, whether there are gaps and lines similar to linen.

1. Porcelain clay

Distinguish the old porcelain can look at the porcelain clay, the old porcelain in the production of the porcelain clay has been manually washed, so the porcelain clay appears clean, some old porcelain porcelain clay looks both powdery, and fine-grained. The porcelain clay of the new porcelain looks very delicate, with almost no impurities, and the carcass is relatively light and thin, without a sense of heaviness.

2. Density

Distinguish the old porcelain from the old to see the density, the old porcelain in the production are artificially muddy, so the density of the fired porcelain is suitable, there is no excessive density or too loose phenomenon. The clay blanks of the new porcelain are made with a mud refining machine, so that the density of the porcelain produced is too large, and some new porcelain is made by the grouting method, and the density is too loose.

3. Fetal quality

Distinguish the old porcelain can look at the thickness, the old porcelain in the making of the ware through the stale process, coupled with its exposed part of the long-term contact with the outside material and air, after weathering and absorbing nutrients, resulting in the old porcelain fetal texture has a sense of moisture. The fetal quality of new porcelain is generally relatively dry, and sometimes the surface of new porcelain is only a touch of light, bright but not moist.

4. Specific methods

After getting the porcelain, you can look at the bottom first, the bottom of the old porcelain should have traces of friction that have been used, and the new porcelain without traces of use can be seen, and you can see the degree of new and old at the bottom. You can also see the luster, the light of the old porcelain is from the inside, warm and eye-catching, and the new porcelain will have highlight points, bright and dazzling.

Then touch it with your hands, some old porcelain has agate added to the soil, which not only looks smooth, but also feels like a piece of jade. Then you can listen to the sound, the old porcelain tends to have a higher aluminum content and a dull sound when gently tapped, while the sound of new porcelain is brittle.

Finally, weak acids can be used.

Washing the tire, the surface of the old porcelain will not be easily washed off, and the old new porcelain tire can be washed off. In addition, for people with a relatively high level, they can also judge the age of porcelain from the aspects of charm, ornamentation, painting techniques, etc., combined with books and materials.
