First of all, the oil: Hetian jade feels oily on the hand, which means a slightly slippery feeling of resistance, just like holding a piece of oil in the hand and pushing it with your hand. There is a feeling that the oil has to be opened.
Secondly, it is sticky: it has a slight roughness, because the seed material has the "pores" characteristic of tens of thousands of years of running water. Then it feels a little resistance and feels. In addition, Hetian jade's ambiguity also makes the oily slip with a sense of resistance.
Hand feeling: Because the density of Hetian jade is larger than the density of general jade, the hand feel is heavy, and the specific gravity reaches between 2.9 and 3.1. So there is a feeling of pressure in the hand, the hand feels full weight. Different varieties have slight differences. Generally, the density of Hetian Qingyu is relatively large, and the density of white jade and ink jade is small.
Cold: When you touch Hetian jade, you will feel cold and smooth, because Hetian jade has good thermal conductivity and can quickly transfer the heat from your hand. This kind of heavy, cold feeling when Hetian jade started was unmatched by other jade.
Slip: If a piece of jade is slippery, it means that it has no "pores" or insufficient thickness.
涩: It means that the hand feel is too rough, it may be artificial frosted imitation seeds or jade is too bad. The feel of the granules is sticky, which is too slippery and too sloppy.
Russian material: Although the Russian material also has a glass luster, it has a slight porcelain feel. The white jade appears to be “dead whiteâ€, and the hand feels more dry. There is no sense of warmth composed of Hetian jade by oiliness and moistureiness. In addition, due to the coarser grain size. It feels lighter.
