Jade can't be directly exposed to the sun, which will damage jade and affect its luster. Therefore, if you accidentally expose jade to the sun for a long time, you must do a good job of "after-sun care". You can put the jade in a box and put it in a dark and humid place for a while. At this time, there will be some fog on the jade, and then gently wipe it with a soft towel.
Extended data:
Distinguish the quality of jade;
Color: The white of white jade is often slightly blue, and there are very few people who are extremely white and pure white, while nitrate is even white and pure white. After the light is on, nitrate still has a slight orange light.
Jade: One of the characteristics of jade is moist, even and greasy, like cream, while the feeling of nitrate is bright, but it feels naked, but it feels like a thief's light flashing in the brightness.
Impurities: There are no bubbles in jadeite, but there are bubbles in nitrate. Sometimes it is difficult to be observed because of its translucent color, and sometimes it is rare because of its good quality. Sometimes it can be detected from the surface. If there is trachoma, that is, there are bubbles on the surface, it can also be proved to be nitrate, because white jade does not have this characteristic, and the bubbles inside can also be detected under strong light.
