Why can t the hair on the surface of the jade be burned?

If you tie a hair to a glass and burn it, it won't break! You can also use agate! This is not an accurate identification! This is to see the real and fake, this is a relatively simple way to identify the real and fake!

1；It is to stick the jade on the face, and it feels very cold, and after two or three seconds, it is not cold, which means that it is true. Because jade transfers heat quickly and dissipates heat quickly! If it doesn't cool on your face, it's fake.

2；That is, the magnifying glass should look at the crystals inside 10 or 30 times to see if there are any small cracks like spider webs, and whether the color is on the cracks or on the surface of the jade, if there is, it is fake. Hetian jade looks like rice cereal, because the crystals are more delicate and the color is more uniform. Some jadeite looks like fly wings, some like a little sand star, and some like broken glass, because the jadeite crystals are not delicate enough, the color is not uniform, and there are many colors on the same piece of jade.

3；It is the identification of destruction, and it is burned with fire. It's blackened, burnt, yellowed, and smelly. Black and yellow, if the water can't be washed off, and the original color is different, it's fake.

Burnt and smelly that's more fake. (If the fire is really burned, there will be small droplets of water attached to the surface of the jade, and when it is blackened, it will return to its original color when it is washed with water.) However, we generally don't use this method, which is not good for jade.

The denser the texture of jade, the better its thermal conductivity. The heat of the flame is quickly conducted by the jade, and the hair or thread wrapped around the jade will not overheat and burn immediately.

If you're not afraid of pain, you won't burn if you wrap it around your fingernails. This does not determine the authenticity of the jade, it is just a matter of ignition point.

It's not that it can't be burned. A short time is doable, a few seconds. This method of identifying jade is not very effective in my opinion. It's okay to scam the layman.

Put the hair in the jade.

It is used to prove the authenticity of the jade, and there is no scientific basis for this method. Hair is not at all.

There is a principle of rapid heat transfer, and jade is a conductor of heat, and the thermal conductivity is very fast, so the hair is not burned.

However, when the fire burns the hair to a certain ignition point, the hair will also burn out. And in addition to jade, as long as the surface is smooth and the hair is tied tightly, many materials can make the hair burn continuously, such as glass products, stainless steel products, etc. This method can only be used as a reference, and cannot be used as a standard for judging whether it is true or false.

No. bai

Put the head on the glass or porcelain piece (silicate mixture) and burn continuously, because the DAO will undergo heat transfer, the ignition point is not reached, and therefore it will not be fired.

Rebirth burning. Answer.

The first and foremost reliable way to distinguish is to see, hear, and test. Secondly, there are three contents of detailed identification of jade, one is to identify the quality of jade, the second is to identify manual processing, and the third is to identify counterfeit products and even synthetic products.

Look, mainly look at the crystal transparency, the real jade has strong transparency, and the grease is luster; Listen, Zhenyu's voice is crisp, on the contrary, the voice is hoarse; In the test, the real jade was scratched through the glass, leaving scratches on the glass, while the jade itself was not damaged in the slightest.

Common fake jade includes plastic, colored glass, marble (marble), electric fake jade, jade made of jade powder and crystal and salt water, and jade imitated by glass, etc., and the means of identification are also different. The texture of plastic is lighter than jade, the hardness is poor, and it is generally easy to identify. Tinted glass is also easy to distinguish, as long as you take it to the light or check in the sun, you will see that there are a lot of bubbles in the glass.

It's ridiculous, I'm giving you a lesson upstairs.

None of the explanations are correct, they are all half-knowledgeable.

The head of the board burns constantly This is the physical right.

The nature proves that this thing conducts heat quickly, and it burns like other stones that conduct heat quickly, so it cannot be proved to be jade.

The hardness of jadeite is about 8 Generally, there are 26 kinds of water The knife does not move, which is determined by the hardness, and the glass can be scratched (the same as the stone, this can only prove 1 of the points, but it is absolutely incomplete) The comprehensive is based on experience, and the jade generally has natural cotton inside the jade B goods are pickled and miscellaneous, and c goods are pickled and impurities, and the filling color is also based on experience, don't think that it looks good and is cheap, some ugly but expensive.

The hardness of Hetian jade is about 6, there are many types, and the glass can also be scratched, but the market is flooded with a large number of Gobi rocks to pass off as Hetian white jade, Xinjiang white jade, which is actually a stone, which depends on professional institutions to test or experience.

Xiuyu includes several kinds of serpentine jade, the hardness is a little lower, but it has a very good color ** is also moderate This kind of knife can be scratched The identification method is to scratch the edges and corners of the glass without damage It is also from the hardness of the premise is to judge whether it is true It is best to have a professional organization to recognize.

There are many others, such as Tianhuang, Duyu, Huangwax Stone, etc., all rely on experience or China Quality Inspection Center jewelry identification.

This is a more traditional inspection method! It can prove the authenticity of jade!

Rumor!!

Both the fake and the real can be burned ...

No, you tie your hair to a stone the same as you tie it to a jade.

Legend. Personally, I don't think so.

Not necessarily, put the glass as burn constantly.

There will be no noticeable change in the burning of jade. In popular terms, the beautiful stone is jade, jade is the essence of the stone, Buddhism is called the earth relic, it is a spiritual stone with the ability to dispel evil and avoid evil, and it is widely welcomed in various regions of the world (especially East Asia) The classification of a gemstone.

1. Broadly speaking, as long as it is a beautiful stone, it is jade, including Lantian jade, Hetian jade, Xiuyan jade, Burmese jadeite jade, Nanyang Dushan jade, serpentine jade, quartz stone jade, crystal stone, bloodstone, calcite jade, lapis lazuli, agate, coral, glacier jade, marble jade and other gemstones.

2. China is the earliest and most extensive country in the world to mine and use jade. There are many records in ancient books, and the names are also very miscellaneous, such as water jade, relic jade, peiyu, fragrant jade, nephrite jade, etc. The tremolite nephrite jade block unearthed from the Chahai site in Fuxin City, Liaoning Province, is about 8,000 years old (early Neolithic Age), and is the earliest true jade known in the world so far.

Fake, without scientific basis. You can use: water identification method to drop a drop of water on the jade, such as a dewdrop that does not disperse for a long time; The droplets disappear quickly are counterfeit goods.

Hand touch method If the real jade is touched by hand, there is a feeling of cold lubrication.

Inspection method Orient the jade to the light, such as sunlight and light, if the color is clear and the green color is evenly distributed, it is the real jade.

Tongue licking method The tip of the tongue licks the real jade, which has an astringent feeling; Fake jade, on the other hand, has no astringent feeling.

Magnifying glass** Put the purchased jade under the magnifying glass**, mainly whether there are cracks, those without cracks are high-quality jade, and those with cracks are secondary. Even if it is a real jade, the value of the cracks is greatly reduced, and the more cracks and the more obvious the value, the lower the value.

The jade is cool, tied with hair, burned, and the hair should be able to withstand the burning for a while.

Then, Shinyu will make you feel cold in your hands when you are outside at night.

Also, if you look at the light, it should be a jade flower like a cloud.

It should be true. I tried.

In the traditional jade industry, there is indeed an identification method for hair tied tightly to jade, burned with a lighter, and the principle is as follows.

Principle: The specific gravity of jade is larger than that of most counterfeit products, so the thermal conductivity of jade is relatively good, therefore, the hair is tightly tied to the jade and burned with a lighter, and the heat of the lighter is conducted away through the jade behind the hair, so the hair is burned.

Application: However, for now, many vitrified glasses, lead glasses, etc. have very good thermal conductivity, so this kind of traditional identification methods are somewhat inaccurate.

Modern methods for jade identification.

Structural method: jade has a certain structure, and it is not jade that does not meet the corresponding structure, such as the fiber interwoven structure of jadeite, the felt-like structure of Hetian jade, etc.

Fluorescence method: jade is generally not fluorescent (except fluorite), so the use of 365nm wavelength ultraviolet light irradiation, will not fluoresce, fluorescent is generally for glue injection products.

Refractive index method: Use a refractometer to determine the refractive index of jade, and compare it with the refractive index table, you can easily judge the type of jade and the authenticity.

Scientific explanation: jade is a good conductor, it will quickly remove the surrounding heat, so no matter how hot the weather is, the real jade is always cool. The hair is tied to the jade, and as soon as the fire burns, the jade will quickly dissipate the heat, and the hair will naturally not be able to catch it.

Thank you for the trouble to adopt!

First of all, jade's own characteristics are relatively smooth and have good heat dissipation; Again, when the hair is tied to the jade and burned with a lighter, the flame temperature of the lighter is not particularly high, and the contact surface between the flame and the hair is much less. If the landlord is told to use this method to verify the authenticity of the jade, I advise the landlord to find another method. If you don't believe me, you can try tying your hair to other smoother stones or metals, and your hair will burn like it.

Summary. No, jade is not flammable, so lighting it with a lighter will not burn out under normal circumstances. However, it should be noted that if there are paints, pigments, paints and other flammable materials on this jade, it may cause disaster if it is ignited by a lighter, so special caution is required.

In addition, when using a lighter to heat jade, you also need to be careful not to overheat it, as overheating will affect the texture and color of the jade.

Is there any paint or pigment on this jade?

There is no overheating pro.

It's excessive. This is mutton fat white jade, and the top is old green skin.

Uh-huh, overheating can affect the color and texture.

Will it explode if it's too much?

Yes, if the jade is burned excessively, it may explode in the case of extreme dryness, and this situation has great requirements for the firing temperature and production process of the material.
