Why is Hetian jade cold? What is Hetian Jade?

Jade is a good conductor of heat. Real jade, heat conduction is very fast. If you touch it with your hands, you will feel a little cool.

This principle is similar to the principle of watering in the ground in the summer, not that the temperature of the water cools down, but that the water absorbs heat before it evaporates, lowering the temperature of the room. When touching the jade with the tip of the hand, the heat will be quickly directed to the jade, and in an instant, it will be quickly directed into the air, so that the air temperature will increase and the temperature of the finger will decrease. The jade only plays a conductive role, and the energy is still conserved.

Put the jade on, or hold it in your hand, and feel cool for a while, because of its good conductor nature, after a while, the jade will be equal to the body temperature, and then expose it to the air, and you will find that in a moment, it will return to the original very cool and cool temperature. This is the embodiment of its fast heat conduction, the faster the heat conduction, the better the quality of the jade.

Hetian jade conducts heat slowly, so you feel the jade cool!

Due to the tight quality of Hetian jade, it is difficult for external substances to penetrate its body! When you sweat, the heat is big, and the heat can't penetrate into the inside of Hetian jade! Therefore, there is a large temperature difference between your body surface and Hetian jade, and you naturally feel that the jade is cold!

Hetian jade is cool, its jade is dense, the thermal conductivity is poor, the temperature changes little, when placed naturally, it is in a slightly cool state for a long time, and it will not heat up easily when worn on the body, often giving people a sense of coolness. In summer, the temperature is high, the weather is hot, and people are irritable, so wearing Hetian jade on the body can play a role in cooling down the heat to a certain extent, relieving the wearer's irritability, and calming down. When wearing, Hetian jade should be avoided in a high-temperature environment, so as to avoid the molecular gap becoming larger, expanding by heat, and causing cracks.

Hetian jade should be cool, its jade is dense, the thermal conductivity is poor, and it is often slightly cool when placed naturally, and it is not easy to heat up when worn on the body. In summer, the temperature is high, and people are irritable, so putting Hetian jade on the body can cool down the heat to a certain extent and relieve irritability. When wearing, it should be avoided close to high temperatures, so as to avoid it expanding by heat and causing cracks.

Because its jade is dense and has poor thermal conductivity, it is often slightly cool when placed naturally, and it is not easy to heat up when worn on the body. In summer, the temperature is high, and people are irritable, so putting Hetian jade on the body can cool down the heat to a certain extent.

Because jade is a special stone, every piece of jade feels cool, but after wearing it for a long time, it will feel warm.

Jade is originally a stone.

Hetian jade, one of the four famous jades in China, is the first of the four famous jades in terms of popularity.

Hetian jade, in the traditional narrow sense, specifically refers to the jade produced in Hetian, Xinjiang, and is also named after Hetian, Xinjiang. However, in terms of a broad scope, Hetian jade refers to nephrite (real jade), and China calls stones with tremolite components of more than 98% of the stones Hetian jade, which are also within the scope of the national standard.

The main origin and characteristics of Hetian jade:

The overall quality of Xinjiang Hetian jade is high, and the market is relatively higher than that of other origins, especially good seeds.

Russian white jade, although the origin is similar to Xinjiang Hetian jade, there are also differences, the Russian material has very little seed material, most of it is mountain water material and mountain material. The characteristics of the outer skin of the mountain material are "sugar skin white jade", "white skin white jade" and "gray skin white jade", the output of mountain material is large, the block is also large, the transparency is poor, and the texture is not fine and waxy enough. The mountain water material is similar to the mountain water in Xinjiang, but there are some differences in color and light color.

Qinghai white jade, only mountain material, large, gray-white wax-white color, transparency is higher than Xinjiang white jade and Russian white jade, but common cotton-like cotton or black-brown spots.

Korean white jade, commonly known as "Korean material", its overall quality is low, blue-yellow or light brown, waxy light sense is obvious, texture structure is relatively loose, "Korean material" generally belongs to the low-grade material in Hetian jade, rich reserves, low mining difficulty, large output, but many collectors still do not accept, so ** compared to Qinghai and Russian material to be cheap.

Hetian jade is a kind of tremolite-based stone, which used to mainly refer to the stone produced in Hotan, Xinjiang. But now the country has defined that as long as it is tremolite, it is called Hetian jade.

1. Touching jade is a good conductor of heat. Real jade, heat conduction is very fast. The jade only plays a conductive role, and the energy is still conserved.

Put the jade on, or hold it in your hand, and feel cool for a while, because of its good conductor nature, after a while, the jade will be equal to the body temperature, and then expose it to the air, and you will find that in a moment, it will return to its original very cool and cool temperature.

2. Look at the jade is translucent, some with a little green, usually called "cui", the more cui, the more valuable. Some live jade only has a little emerald when it is first bought, but after wearing it for a long time, jade raises people, people raise jade, and emerald will become more and more, and jade will appreciate in value. This piece of jade is covered in greenery, and it is still growing.

3. Knock If there is a certain piece of real jade in your hand, take the stone that needs to be identified and knock it with it, if it makes a crisp sound, it is likely to be real jade. If the voice is quite strong, then congratulations on buying a fake. But don't take it directly with your hands when you knock on the jade, you should tie the two with a thin wire, and then swing the thin wire to make the two collide.

4. The five unique cheats for burning and identifying jade are simple in the front and complex and difficult in the back, but they are also more awesome. The fourth method also uses the thermal conductivity of jade to pluck off a long hair, and then wrap her tightly around the surface of the jade and burn it with fire, and you will be surprised to find that due to the good heat conductivity of jade, it is impossible to burn your girlfriend's hair in a short period of time.

Not.

The advantages and disadvantages of jade are identified as follows:

1. Color. The white of white jade is often slightly bluish, and there are few extremely white and pure white, while the glass is a uniform white and pure white. After the lamp shines, the glass still has a slight orange light.

2. Jade. One of the properties of jade is that it is warm and even, like a paste like fat, and although the glass is also moist, it feels that the essence is exposed, and in the moist, it feels that there is a thief light flashing.

3. Fracture. This is a clear distinction between the fractures of white jade and the stony of white jade, which is dull and jagged or jagged, while the fractures of the glass are of material nature, with bright ballast and light and shell-like. Although the jewelry appraisal cannot be used for destructive testing, it can be observed by some accidental bumps, unpolished surfaces, edges and corners, etc.

4. Impurities. There will be no bubble eye in the jade, but there will be bubble eye in the glass. Sometimes it is not easy to observe because of the translucent color, and sometimes it is very rare because of the glass***. But as far as identification is concerned, it is impossible to stop without finding proof.

Sometimes we can inspect it from the surface, such as trachoma, that is, the appearance of bubbles on the surface, it can also be proved to be glass, because white jade does not have this characteristic, and the internal bubbles can also be examined under strong light to get to the end.

5. Specific gravity. The specific gravity of the jade is in between, and the glass is on the left and right, and the glass is lighter in comparison.

6. Sound. The sound of jade is dignified, while the sound of glass is crisp, and in some cases it can be recognized by the difference between the sound of jade and glass by a gentle touch.

To distinguish jade, you should "look at it and touch it". The lights in the jade shop are generally bright, and they know how to "complement each other" with jade, so they should avoid such light in the first place. Secondly, see whether the color is thick, yang, pretty, positive, and harmonious, if there are any, it is a good jade; On the contrary, if the jade is light, yin, old, flowery, and oblique, it is inferior jade.

There is also the feeling of relying on the hand to see if the jade is cool enough, and good jade gives people a feeling of "cool in the heart".

This is not necessarily, there is a kind of jade with a sense of warmth, which is called warm jade!

Hetian jade is not cool to the touch is not necessarily fake, because it has a certain thermal conductivity, and when it is close to the temperature of the human body, there is no cold feeling to the touch. Moreover, everyone has a different perception of temperature, so the accuracy of judging the truth and falsehood according to the temperature is not high. To distinguish the authenticity of Hetian jade, it is best to judge according to various aspects such as structure, fineness, oiliness, gloss, and hardness.

Hetian jade is not cool and not necessarily fake Hetian jade is composed of minerals and has a certain thermal conductivity, and it is not cool to the touch during wearing, which does not mean that it is fake. The authenticity of Hetian jade cannot be distinguished by whether it is cool or not, because when the temperature of Hetian jade is close to that of the human body, it will not feel cold to the touch.

Everyone's perception of temperature is different, so Hetian jade is not accurate in judging the truth or falsehood according to the temperature. Generally, the authenticity of Hetian jade should be judged according to various aspects such as structure, fineness, oiliness, and gloss, in order to draw an accurate conclusion.

When distinguishing the authenticity of Hetian jade, it can also be distinguished by hardness and sound, usually the real Hetian jade is hard, and it is not easy to scratch when scratching the jade surface with metal objects. When tapping, the voice of the real and Tianyu is crisp and loud, and the fake one is relatively dull.

Cool first and then warm. Hetian jade is a metamorphic rock formed by contact metasomatism between magnesia marble and moderately acidic magmatic rock, which contains multi-mineral aggregates such as tremolite, hornblende, actinolite, etc.

When Qin Shi Huang unified China, Hetian jade was called "the jade of Kunshan" because it was produced in Kunlun Mountain, and later it was called "Khotanese jade" because it was located in the territory of "Li Lacks Khotan". It was not until the ninth year of Guangxu of the Qing Dynasty (1883) when the Hetian Zhili Prefecture was established that it was officially named "Hetian Jade".
