It is easy to engage in appraisal and say that everything is false, and it is easy to show their unique eyesight that is not ordinary with ordinary people. Many "Mr. NanGuo" in the antique world have followed suit. In fact, the difficulty is to pick out the real things at a glance from thousands of fake things! That's eyesight! Of course, for an eyeless antique, it is understandable that it is not true or false. Some people say, "It's so hard to identify the true and false porcelain, I won't play!" And I think, "It's so hard that it's so much fun!" A road that is always full of magic and has no end is the most exploratory and challenging fun, and the real charm of porcelain is also here!
The author believes that the difference between genuine ceramics and fakes at present is as follows: 1. The difference in process. The ways and methods of firing porcelain in ancient and modern times are different. The artistic sense and aesthetic perspective are also different. The porcelain made naturally presents a different aesthetic. 2. Years. Genuine products are old, and fakes are generally new imitations. 3. Scarcity. Genuine products are non-renewable. Counterfeits can be produced without restriction. 4. Value. Things are more expensive than rare, and genuine products are often worth much higher than fakes. The production of counterfeits is often due to the high value of genuine products and imitate genuine products.
Although some of the high imitation porcelain produced by the anti-identification hand method in the market today is indeed very similar to the real thing, the appraiser will also achieve "one foot high and one foot high" in the process of continuous learning, and there is still a difference between ancient porcelain and new porcelain.
Ancient porcelain ornamentation and utensils, its painting method and engraving method are natural and smooth, although the new porcelain is skilled in brushwork, it is inevitable to be stiff and rigid, just like writing, one person and one kind of brushwork, different, words like its people, imitation words can be imitated, not easy to imitate God.
New porcelain will leave unnatural traces of copying during the imitation process. Another point worth noting is that the ancient porcelain blue and white model is deep under the glaze, and the new porcelain blue and white style seems to float on the glaze. Due to the long-term erosion of natural air dust and scale, coupled with the change of temperature, the glaze molecules are lost, the glaze is opened tightly, and the opening pieces of new porcelain are cracked.
Due to the different ancient and modern porcelain-making processes and the formula of tire and glaze raw materials, the outer edge of the ancient porcelain shrinkage glaze is rolled up, and the new porcelain shrinkage glaze is closely related to the blank. Although some new porcelain is old, it can still be seen that there are flaws when you look closely at the subtleties of the glaze.
Due to the age of ancient porcelain, the glaze of the utensils is deep and warm, and the light is emitted from within, and this light is naturally formed.
New porcelain often has a layer of glaze, bright and dazzling, or called "raw", that is, the use of matting agents or other methods to remove the surface floating light, will not show the ancient porcelain warm lustrous glaze will have countless fine marks, stains, loss of luster, but also lost the charm. The painting of ancient porcelain, the color is calm and subtle, and the color and the cover of the tire are bonded naturally. However, after the colored utensils, the color of the place where the color is added is particularly bright, the gloss is strong, and it looks dazzling.
Another example is the melon skin green in ancient porcelain, which will be silvery over the years, and there is a layer of silver light color on the surface of the utensils, which is very natural, and this natural silver new porcelain cannot be imitated.
The gold of ancient porcelain will wear and change color over time, or leave only traces. The imitation is brightly golden and not easy to peel off. Ancient porcelain has a back-painted gold color, and if you look closely, there will be traces of peeling off the original gold.
In addition, the color of gold color on ancient porcelain is also different, and the gold on porcelain before the Daoguang decade of the Qing Dynasty (1840) is generally depicted with gold powder, and the gold is deep and stable. After 1840, the imitation of ancient porcelain is painted with gold and water, although the gloss is good, but it is not as dark as before.
Distinguishing between ancient porcelain and new imitations must look at the bottom foot. Just like brand-name clothing, one depends on the layout, and the other depends on the treatment of the corners. Distinguish between truth and falsehood in the subtleties.
Generally, the tire quality of the ancient porcelain bottom foot exposed tire has a kind of maturity. Due to the age, some dust has been immersed, but the dust has been eaten into the fetus and immersed in the tire tightly.
The tires at the new imitation exposed tires are biological. Its dust floats on the surface, and some are glued with glue mixed with dirt. Some ancient porcelain shows a unique color due to the particularity of raw materials. It is also beyond the reach of imitations.
For example, the Longquan porcelain carcass contains more iron elements, and the foot edge of the utensils after firing shows iron red, which is called "secondary oxidation". Imitation of Longquan porcelain, the shape of the vessel, glaze color can be chaotic, but the practice of the bottom foot is different from ancient times.
The rust on the excavated ancient porcelain will be immersed in the porcelain interior, which is closely combined with the porcelain glaze and is not easy to remove. Forged unearthed porcelain on the rust, some are mixed with glue and soil to glue, if the glue is not used, the rust is loose, floating but not solid, a little touch, rust spots will be scraped off.
The sound of ancient porcelain tapping is crisp, which is due to the delicate tire quality and the tire nature is ripe. The sound of the new porcelain buckle is short and dull, which is due to the birth of the fetus, just like stone, pay attention to the raw pit or cooked pit, the raw pit refers to the newly mined stone. There is a natural nature.
