Recently, I heard from my friends that the longer the Hetian Yudai, the more the color will become yellower. So, is this really the case? Generally speaking, the color of Hetian jade white jade does not change much. The jade of real material is relatively stable, and it usually does not change much when it is worn and played normally. If there are changes in depth, this may be related to your usual maintenance and length of wearing. First of all, Xiaobian will analyze the reasons why Hetian Yuyue wears yellow: 1. From the jade, there are some jade materials that are relatively unblocked, and it is easy to turn black and yellow. For example, the Russian material in Hetian jade, its structure is rough, and it will gradually turn yellow when worn for a long time. Therefore, when we choose jade, we should try to pick the material as stable as possible, which is not so easily affected by external factors, such as Xinjiang Hetian seed jade. 2. Jade will have an oxidation effect, because there will be some iron elements in Hetian jade. When these iron elements are in contact with air, they will produce an oxidation effect and produce iron oxide. Therefore, the color of jade will also have a little yellow of iron oxide, so we feel more and more yellow. In particular, Hetian jade of the mountain material is mined and cut into contact with the air, so it oxidizes very quickly. 3. The sweat secreted by our body slowly stays on the surface of the jade. If we don't clean for a long time, then the sweat will make Hetian jade gradually turn yellow and black, and the quality of Hetian jade will be degraded. 4. There is also a way we usually do not care about jade maintenance. The real jade is relatively stable and will not find too much color change. However, the yellowing of white jade is the most obvious in Hetian jade, because many white jade will gradually turn yellow and black after being played for a long time. In fact, this is because we are not properly maintained. SHAOXING YINGSIPE TEXTILE CO.,LTD , https://www.chinayingsipei.com
