Hetian jade identification, oiliness is a very important factor, but also a term we often hear. There are still some questions about the oily and oily degree of Hetian jade. The following is a simple popularization. Let me tell you where the oiliness of Hetian jade comes from?
In addition to the feeling of oily, Hetian jade can also be felt in the sense of touch. The feeling that Hetian jade looks oily is mainly the reason for the hardness, shape and arrangement of Hetian jade mineral particles. Under normal circumstances, when the light is refracted or reflected on the surface of Hetian jade, the characteristics of Hetian jade's internal mineral particles make the reflected light more soft than the irradiated light, and the special luster of Hetian jade will form a A grease luster that is weaker than glass and stronger than waxy luster.
Hetian jade's oily feel is generally affected by three factors: the degree of detail, the polishing process and the playing time. In general, the finer the mineral particle structure of Hetian jade, the stronger the oily feeling, the weaker the opposite; the different polishing process will make Hetian jade different in oily feeling; the longer the playing time, the stronger the oily feeling of Tianyu .
