黄龙玉为什么会褪色

Huang Longyu is also hot in recent years, but some people who bought Huanglongyu will encounter some problems. For example, if jade wears and wears, it will fade. Is it a fake or a reason? Today, Xiaobian will explain why Huang Longyu will fade.

First of all, Huanglongyu, like ordinary jade, will have some fading phenomenon, especially deep pits, and the deeper the pit, the more obvious the fading phenomenon.

When Huanglongyu is buried underground, it is in a state of strong pressure, constant temperature, no light, constant water, and lack of oxygen. This is a very stable state. When it was taken out, the environment in which it has undergone tremendous changes, the nature of the original stable chemical, there will be a process of re-adapting to the new environment. Of course, the phenomenon of fading, cotton, etc. in this process is very normal. But this process of change will not continue indefinitely, and after a period of time, it will reach stability again.

In short, there will be some changes in the deep pit stone, which is certain. Since the puddle material and the semi-mountain material are on the surface for a long time, there will be no change or some small changes. Moreover, the yellow and red series of yellow dragon jade coloring are the final stable products of iron element oxidation - ferric ions, namely rust yellow, orange, iron red, brown, so it is stable high-priced iron ion coloring.

There is also a fake fade. The specific appearance of this phenomenon is that the coloring ions do not change. In the dry environment, the jade dehydrates and causes it to scatter light, which causes the light to refract and reflect, which causes the human eye to feel the illusion. When this happens, it is often refueled or often played, and it can be restored to color.
