1. Jade bracelets become hot after being rubbed by hand for a period of time, even a little hot, and then cool after being left for a period of time, which is not an objective criterion for judging whether they are A goods. This phenomenon occurs in crystals and agates. Density measurement: 33 ~ 34g/cm3. Spot measurement: refractive index 66 infrared spectrum: typical absorption peak amplification inspection of jadeite: fiber structure is not filled.
2. When the jade bracelet is hot in hot water, it does not give off heat, but because the heat of external hot water is transferred to it, making it give off heat.
3. Jade bracelets are not hot, and jade should not be hot. Jade is not suitable for high temperature and high fever, and you can't wear bracelets to soak in hot springs.
4. Because jade has good thermal conductivity, the water is hot, and it dissipates slowly after absorbing heat, so you will feel that the jade bracelet is a little hot, and it will be normal after a while.
5, it should not be the problem of the jade bracelet itself, but largely caused by the short-term paralysis of the cold and heat receptors on your wrist skin. Unless you fixed the evidence by scientific temperature measurement at that time, the short-term fever of the jade bracelet is puzzling and there is no scientific explanation. The physics teacher in high school asked if you could accept this answer.
How is it that jade is very hot after playing for a while?
1, jade handle, it is normal to have a certain temperature after playing, but it will not exceed the body temperature of the player. Otherwise, it is abnormal. It is suspected that it is not natural jadeite, but may be a synthetic product.
2, jade pendant, it will get warmer after wearing for a while, which is a normal phenomenon, not an objective basis for judging whether it is true or not. To judge the authenticity of jade, it is necessary to trouble the authoritative jewelry and jade appraisal institution to identify it with instruments and then issue an appraisal certificate.
3, jade pendant will be hot when worn for a long time, which is caused by accepting the heat of the body, normal.
Why does the jade handle get hot when you play with it for a while?
Hotan jade's handle is getting hotter and hotter because Hotan jade has better thermal conductivity. However, Hetian jade was cold when it was first acquired. The longer it was worn, the temperature of Hetian jade itself would tend to human body temperature, which was similar to human body temperature to the touch.
It is normal for the jadeite handle to have a certain temperature after playing, but it will not exceed the body temperature of the player. Otherwise, it is abnormal. It is suspected that it is not natural jadeite, but may be a synthetic product.
Second, look at the thermal conductivity. Jade A has strong thermal conductivity, and it takes a short time to get close to the body temperature on the hand and a short time to cool on the glass. Third, you can look at the feel. Natural jade feels greasy.
Why is there such a change? In the jade bracelet, the hair color factor in the color is not completely solidified, but it will still play a role, and the sweat in the human body also plays a very key role. There is a substance in jade called chromium.
Friction heat generation is a basic physical phenomenon, so is any material. Hetian jade is no exception. It is normal to rub it with your hands.
First of all, we must determine whether our jade bracelet is true, and secondly, whether it is Hetian jade. If it is not true, it is an allergic reaction. Just go to the hospital for an allergy test.
