How to identify jade? Chinese jade is divided into two categories: nephrite and jadeite. If you don't ask an expert, you should first judge the true and false of jade, you can observe it from three aspects, let's take a look!
First, because the glass texture is very brittle and hard, the structure is unblocked, lacking the compactness and toughness of jade, and can not withstand the high-speed rotary engraving, so high relief and round carving are generally not processed on the glass.
Second, use a magnifying glass to find bubbles, even if you can only see one, you can confirm that it is not jade.
Third, glass added chromium oxide, color near ruby; added cobalt oxide, color near sapphire; added chromium oxide and copper oxide, color near emerald ... and so on, there are many kinds of fake jade. However, their color tone is always thin, lacking the natural oily and lustrous feeling.
The identification of new jade and old jade is different. The identification of Xinyu focuses on the true and false varieties, the quality of the texture and the fineness of the carving. The identification of old jade is relatively complicated. In addition to several basic requirements for new jade, it is also necessary to identify the production of jade and its historical value.
