Jade sound identification method
The method to identify the sound of jade was as follows: the usual method was to bind the jade bracelet with a thin thread and hang it in the air. Then, use a rubber rod or glass rod to gently knock the jade bracelet and observe the sound it made. The sound of natural jade was crisp, similar to the sound of metal colliding, while the sound of glued and colored jade was dull and turbid. However, it was important to note that there were many restrictions to identifying jade by listening to the sound. This method was only effective for B grade jade, 83 jade, and some other stones that were disguised as jade. If it was polished and dyed, the sound would be the same. For C-grade jadeite (only artificially dyed, without acid washing to destroy the structure of the jadeite), the sound of knocking was as clear and pleasant as natural jadeite. Moreover, with the development of counterfeit technology, the strength of the organic glue used to fill the "high-grade" jade was very high. The fake jade also had a strong luster, and the knocking sound was very clear. It was almost the same as the A-grade jade, so it was difficult to identify it by sound. Therefore, judging the authenticity of the jade by listening to the sound was only a reference at best. It must be combined with other identification methods to accurately determine the authenticity of the jade, such as looking at the surface characteristics of the jade, comparing the identification certificate, etc. It even had to be taken to a professional appraisal center. Only by using professional instruments to detect the density, refraction index, and Polarized Light of the jade could the authenticity and grade of the jade be determined.

Jade identification method
The method of blood identification
There was a blood drop method and a blood drop method. The bone dripping method was to drip the blood of a living person onto the bones of the deceased, and if it seeped in, it meant that they were related by blood. The blood fusion method was to drip the blood of two living people into a water container, and the blood drops fused into one, indicating that they were related by blood. However, this method lacked scientific basis. In fact, they were not recognizing relatives, but the same blood type. The results were unreliable.
Zodiac Moutai identification method
There were many ways to identify the authenticity of Zodiac Moutai. The following key points could be summarized to identify the authenticity of Zodiac Moutai: 1. Anti-counterfeit label: The anti-counterfeit label of the authentic product uses a special paper. After opening it, the words " National Liquor Moutai " can be printed on the reverse side. There is a fine white frost-like substance on the surface. The labels of the fake goods were made of ordinary paper, which was not exquisite enough and was not transparent. 2. Bottle cap: Genuine bottle cap with exquisite workmanship, bright colors, glittering gold. The cap of the fake wine was mostly golden and dull white, and it felt rough to the touch. 3. " Positive Mark: The diagonal part of the authentic product. The white line is relatively thick, and the last white line is thinner than the previous ones. The white line of the fake wine would be thinner, and the last white line might not be visible. 4. Back label: The words on the back label of the authentic product are clear, printed accurately, and the white space is even. The words on the back of the fake wine were blurry, the size of the white space was inconsistent, and the workmanship was rough. 5. Bottle bottom: The words " National Liquor Moutai " could be clearly seen on the bottom of the authentic bottle, while the fake wine could only be seen as a blurry square. It should be noted that the above method may only be applicable to a specific year of Zodiac Moutai. Different years may have different details. In addition, in order to ensure that you can buy the real thing, it is recommended to choose a formal channel to buy, and pay attention to choosing a reputable collector to trade.
The identification method of Qianlong Tongbao
The identification method of Qianlong Tongbao was as follows: ** 1. Look at the material ** Qianlong Tongbao was made of copper and iron. Most of the authentic products were made of brass or red copper, which had a tight texture and a heavy feel, while the authentic products made of iron would appear dark gray or black. Fake copper was often loose. If it was an imitation made with modern casting technology, its luster would be too bright and it would lack the historical sense of old coins. ** 2. Look at Qian Wen ** The handwriting of the real thing was full, and the knife skills were exquisite. The words were deep and powerful, and there was a smooth stroke charm. The handwriting was natural and harmonious. On the other hand, fakes often had shallow and stiff handwriting, and the strokes lacked cohesion. It looked like it was carved by a machine, especially the words "Qianlong". If the handwriting was rough and unclear, it was likely to be a fake. ** 3. Look at the patina ** The real Qianlong Tongbao would form a natural "patina" due to the passage of time. This was a thin film formed by time. The color of the old coin's patina was deep and natural, smooth to the touch. As for the new imitation of Qianlong Tongbao, although some would deliberately make a patina effect, it was often too uniform and had no traces of natural aging. If one rubbed it gently with their hands, the surface of the fake would often have a rough feeling and even fade. ** 4. Listen to the sound (auxiliary method)** If you have two Qianlong Tongbao, you can tap them lightly. The real one will make a crisp metallic sound, while the imitation usually has a dull or hoarse sound. ** 5. Observe the craftsmanship ** Judging from the overall craftsmanship, the genuine product's casting process was regular, while the fake product was rough and had obvious traces of casting. For example, the words on the front should be very neat and upright, with the same thickness and no flaws. If there is a Manchu or Chinese name of the casting bureau on the back, the same font should be standard and neat. ** 6. Check for wear and tear ** Since the Qianlong Tongbao was a currency at that time, the real thing would have some wear and tear, while the fake one was often relatively new. However, there were also methods to fake the wear and tear effect, so it was necessary to judge from many factors. Watching "Safe Entry" wasn't enough. Everyone, please click to read the novel!
Identification Method of 100% Mulberry Silk
Here are some ways to identify 100% mulberry silk: 1. Burning Method: Pull some mulberry silk from your clothes and burn it with a lighter. After burning, real mulberry silk would have the smell of burnt protein, similar to the smell of burning hair. The burning substance would be black-gray powder, which would be crushed with a pinch. If it smelled plastic, it would form a melted ball after burning, and it would be very hard to touch. If it was not crushed, it would be chemical fiber. 2. ** Appearance Observation **: - The surface of high-quality mulberry silk had a pearl-like luster. It was milky white and slightly yellow, and the silk threads were distributed in an orderly and neat manner. If it looked very "pale", lusterless, with more impurities and messy silk threads, it might be low-quality silk. - The real mulberry silk had light absorption, looking silky and soft, with a soft luster, while the imitation mulberry silk had obvious reflection, dazzling luster, light texture, and rough perception. 3. ** Feeling Judgement **: - Real mulberry silk was soft and elastic. It had good elasticity and was easy to stick to the hand. The longer the thread was pulled, the better the quality. The stretch and elasticity of inferior silk would be much worse. - Mulberry silk has good moisture absorption, is air and heat preservation, has a certain degree of elasticity, feels warm and moist, and has good drapability. It will feel cool and hold hands when touched, and slight wrinkles will appear when grabbed by hands. Rayon and chemical fiber products have a blocking feeling when touched, and will generate static electricity when touched, and have a sense of absorption to the skin. 4. ** Look at the washing label **: The washing label should strictly indicate the safety technology category, implementation standards, and composition of 100% mulberry silk. If it was a bunch of foreign languages, especially the English words "HAND FILM LIKEN SILM", or if it only wrote real silk, mulberry silk, and vinegar fiber without specific proportions, it was basically fake. Some clothes that contained 5% mulberry silk were publicized as mulberry silk products that were passed off as fish eyes. 5. ** Price considerations **: High-quality 100% mulberry silk will not be too cheap. If the price is too low, it may be tussah silk (wild silkworm cocoon, yellow silk color, brittle material, hard texture, easy to break), mulberry silk short silk (inferior silkworm cocoon, treated with chemicals), or cloth with very low mulberry silk content. 6. ** Wetting and breaking method **: Take a few threads from the fabric, wet the threads with water and break them by hand. If it was easily torn and the fracture was too flat, it was fake mulberry silk. After wetting, its toughness increased, and there were different lengths of hair at the fracture, it was genuine mulberry silk. 7. ** Judgment of fire **: Genuine mulberry silk burns slowly and will shrink into a ball. After burning, it will emit a burning smell. There is no open fire. After leaving the fire, it will form dark brown particles, which will turn into ashes when twisted by hand. Imitated mulberry silk fabric will have flames when burned. After leaving the fire, the flames will continue to burn. After the fire is extinguished, spherical hard particles will appear at the edge of the fabric, which will be hard when twisted by hand. 8. Drug identification: Ask the merchant for a small amount of the same cloth as the product you purchased, or take off some silk thread from the edge of the product, soak the cloth in a small cup of 84 disinfectant for about 20 minutes and stir it well. Real mulberry silk was made of animal protein, which would gradually melt. When it melted, irregular small bubbles would appear around the cloth, and finally it would all melt. Fake mulberry silk would not melt, let alone obvious bubbles. 9. ** Shrinkage or not **: Genuine mulberry silk is generally processed by the manufacturer in advance. The fabric is shrunk to the best state of the fiber before it is put on the market, so there is generally no shrinking phenomenon. Ordinary mulberry silk generally does not have this process. It may shrink seriously during washing. 10. ** Wrinkle Free **: The seller randomly grabbed a handful of real mulberry silk clothes during the live broadcast and rubbed them between his hands. When rubbing, a silk sound could be heard. No matter how long he rubbed, after releasing his hand, the fabric immediately stretched out. No wrinkles could be seen, and the elasticity was strong. It felt delicate and smooth. 11. ** Electrostatic prickling sensation **: If static electricity occurs when you try it on, or if you feel itchy and stuffy on your skin, it's likely to be fake mulberry silk. Real mulberry silk is not only anti-static, but also has good breathability and anti-itch function. It's also easy to dissolve in the basic solution of NaClO.

Free jade identification online
Currently, there were some channels that could provide free jade appraisal services. For example, the Nanjing Quality Inspection Institute once launched a quality monthly public welfare inspection activity. During this period, the National Gold and Silver Quality Supervision and Inspection Center provided jewelry and jade identification services to the public for free, but this was an activity for a specific period. In addition, some organizations claimed to provide professional free appraisal of jadeite, but the specific details and authenticity needed further verification. At the same time, although some of the e-commerce platform's appraisal shops had paid appraisal services, they also mentioned that they could provide online appraisal services (for example, jade could be appraised online by providing photos and videos for 10 yuan per piece). There was no general and long-term service that was completely free and specifically for online appraisal of jade. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!

identification method for small clump of water
There were several ways to identify small molecular water. One method was to identify it by observing its appearance. The appearance of small molecular water should be clear, transparent, colorless, odorless, and odorless. If the water was turbid, colored, or had a peculiar smell, it meant that it was not small molecular water. The other method was to identify it by the taste. The taste of the small molecular water should be more mellow than ordinary water, with a faint sweetness. In addition, shaking and standing could also be used to identify small molecular water. After mixing the edible oil and water, shake them up, and observe the color of the mixture and whether it is attached to the wall. After mixing the small molecular water with the edible oil, it is milky white and attached to the wall, while after mixing the ordinary water with the edible oil, it is yellowish white and does not attach to the wall. After standing for a period of time, the mixture of small molecular water and edible oil would remain milky white and hanging on the wall. The above were several common methods to identify small molecules.
