Here are two ways to identify jade glass and ice.
The first point, whether it is fluorescent
This method is relatively easy to identify jade glass and ice species. Because the glass type of jade will have a strong fluorescence; while the ice type jade is very transparent, it does not produce strong fluorescence. One of the things that needs attention is the thickness of the jade. The thinner the jade will look more transparent. This requires extra attention when identifying jade glass and ice. Some merchants like to make the ice jadeite very thin, and then use the K gold inlay and the reflective surface to the bottom, so that the ice jade is very similar to the glass jade. Therefore, when identifying ice and glass, it is necessary to consider the thickness.
Second point, transparency
The transparency of the glass is very high, as clear as glass; the ice is like ice, and there is no glass.
