To distinguish its authenticity, it can be observed from three places:
1. Because the texture of the glass is very brittle and hard, the structure is loosely arranged, and the density and toughness of jade are lacking, and it cannot withstand strong high-speed rotary engraving, therefore, high relief and round carving can not be processed on the glass.
2. Use a magnifying glass to find bubbles, even if you can only see one, which is glass.
3. Glass plus chromium oxide, color nearly ruby; Cobalt oxide is added, and the color is nearly sapphire; Add chromium oxide and copper oxide, color near emerald, etc., and many colors. But its tone always looks thin, lacking the oily and rich feeling of natural jade. The more difficult varieties are mainly fake jade made of polymer materials.
Its color can be arbitrarily adjusted, magnifying glass is also difficult to find bubbles, it is said that the infrared spectrometer can immediately show the original shape, but the visual inspection in addition to the general impractical destructive inspection, knock to find the stone section, fire to see its reaction and other methods, the key is to see whether there is a natural stone pattern on the surface. After all, it is unnatural to be artificially processed, and it will be exposed under the magnifying glass.
The identification of jade is divided into two categories: new jade and old jade. The identification of new jade focuses on the true and false varieties, the quality of the texture and the finesse of the carving. Some of the technical aspects have already been covered before.
However, the identification of old jade is not ordinary, in addition to several basic requirements of new jade, it is also necessary to recognize the era of jade production and its historical value.
The confirmation of the historical value of jade is based on a clear era. Familiar with the common shapes, characteristic crafts, and popular colors of jade in various eras. Then refer to the ** on the characteristics of jade in a certain era, and if they are related to each other, your level of dating of jade will produce a rational improvement, and at this time, you should have as much contact with the real thing as possible to correct the parallax between the picture in the book and the real thing.
In addition, the judgment of the era allows a certain span on some jades. Because jade artifacts are more precious and less perishable, there are many precedents for early jade artifacts to appear in tombs hundreds of years later as heirlooms. The late jade of the previous era and the early of the next era are not exactly one-size-fits-all in style.
There is no jade with a dating, and slight discrepancies are normal.
