What is the feel of a good Hetian jade?
Hetian jade is warm and delicate, and has a strong sense of oil. Hetian Yupan is more delicate when played. It is a kind of slightly slippery feeling of resistance, just like holding a piece of oil in his hand and pushing it with his hand. The feeling that the oil has to be opened is the most distinctive aspect of Hetian jade. So, what is the feel of a good Hetian jade?
1. Hetian jade feels oily:
The oiliness of Hetian jade feels a slightly slippery feeling of resistance, just like holding an oil in his hand and pushing it with his hand. There is a feeling that the oil has to be opened.
The oiliness of Hetian jade is mainly:
a, from the visual point of view of the oil luster, which means that Hetian jade's fat light is strong and at the same time has a warm and soft but not glare. It is inseparable from the density, hardness and polishing method of white jade.
b. The oiliness on the hand feels a slightly slippery feeling. The natural Hetian jade holds it in the hand and there is a feeling of holding a piece of oil in the hand. If we push it by hand, there is a feeling that the oil has to be opened.
2, a little resistance:
There is a slight roughness, because the seed material has the "pores" characteristic of tens of thousands of years of running water impact, it feels slightly resistant and feels. In addition, Hetian jade's ambiguity also makes the oily slip with a sense of resistance.
3, Hetian jade's pressure feel:
Because Hetian jade has a higher density than general jade, the hand feels heavy and the specific gravity reaches between 2.9 and 3.1. Therefore, the seed material has a feeling of pressure in the hand, and 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.
4, cold touch:
When the hand touches the seed material, it will have a cold and smooth feeling, because Hetian jade has good thermal conductivity and can quickly transfer the heat from the hand. This kind of heavy, cold feeling when Hetian jade started was unmatched by other jade.
5, the feel is sticky:
If a piece of seed is slippery to the touch, it means that it has no "pores" or insufficient thickness. The hand feel is too rough, it may be artificial frosted imitation seeds or jade is too bad. The feel of the seed material is sticky, which is too slippery and too sloppy.
Rubber Damper, also known as Shock Absorber, Isolator, and NBR grommet, NBR is a unsaturated rubber copolymer with polar unsaturated carbon chains, which is copolymerized by propenenitrile and butadiene, according to propenenitrile content from low to high, the higher the resistance to oils but the lower the resistance to cold. Oil resistance is the greatest advantage of NBR elastomer so it has excellent resistance to petroleum base oils and non-polar solvents but poor resistance to polar oils and polar solvents.
Nitrile rubber (NBR, Buna-N) grommet provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
