The method of distinguishing the true and false bian stone belongs to the category of medical instruments in traditional Chinese medicine. It can be used to distinguish the true and false masonry by various scientific methods such as parameters and magnetic field changes, but experienced appraisers can also identify it through perceptual knowledge. This paper introduces the method of identifying the authenticity of Bian Shi.

What are the methods to distinguish Bian Shi 1 from the real one?

1, Bian Shi belongs to the category of TCM medical devices. Only the products approved by the Food and Drug Administration are formal, and only when they act on the human body can they play a role in regulating diseases.

2. As the Bian Shi products of Tongrentang have always been the best-selling products and the best reputation, many merchants have made false propaganda under the guise of "Tongrentang" recently. Tongrentang has only sold Bian Shi products of Spinibao brand in recent ten years, so consumers should recognize the brand clearly when buying.

3. The mineral crystal size of Spine is small, about 0,03 03mm, with fine surface and high polishing degree. Take the scraping board as an example. The real Spence Stone can be directly dipped in clean water and scraped without scraping oil. When buying, you should read the test report of mineral crystal size clearly.

4. Wearing or using bian stone can speed up the blood flow of human microcirculation by 20%, which is called promoting blood circulation and qi circulation in Chinese medicine, and can be interpreted as "far infrared phenomenon" in modern science. Therefore, bian stone with far infrared characteristics is a good bian stone.

5. When Spine rubs against human body, it will generate 3708 ultrasonic pulses with frequency range of (200-2000, kHz, which is much higher than other materials. This is why Bian Shi Scraping Board is more suitable for scraping. When buying, you should read the ultrasonic parameter test report of the product clearly.

6. Some enterprises only sell trademarks or test results issued by personal testing institutions, and there is no test report issued by state authorities. Product trademarks are only used as brands of Bian Shi products sold by enterprises, and any enterprise can register them.

7. The cost of real stone raw materials in Sibin is very high, and there is not much room for big discounts. The cost of fake stones or fake stones is extremely low, and it is easy to sell them at 50% or 40% discount. The authenticity of Bian Shi can also be distinguished from the price.

8. There are hundreds of real stones in Sibin, and each batch has tens of thousands of fake stones or fakes. Genuine sales enterprises have limited supply capacity, while fake sellers have strong supply capacity. You can also know the truth and falsehood of Bian Shi from the quantity.

9. Depending on the concept of stealing jewelry appraisal certificate, it can't provide authenticity and reliability, or tamper with the production registration batch number, quality and technology implementation standards, enterprise registration and business premises, chemical composition test report, radioactive test report, etc. of relevant state departments in Bian Shi. Wearing or using Bian Shi with unknown ingredients can cause chronic heavy metal poisoning, so consumers are advised to pay attention when purchasing.

10. At present, most of the black stones sold in the market pass off as Spine Stone, but most of the "Spine Stone" sold by merchants have not been tested for chemical elements. What's more, they used the concept of "jewelry appraisal certificate" to steal "microcrystalline limestone" for Spine stone. Some "black-hearted" vendors pass off black marble, lingbi stone and even building stone as "Sibin stone" to deceive consumers.

Correct method of distinguishing true and false bian stone

1, thin-section microscope observation method. A small piece of rock was cut from the fixture and made into thin slices, and the photos were taken under the polarizing microscope, and compared with the polarized micrographs of the standard thin slices of Sibin pumice.

2. Infrared spectrum. The infrared spectrum curve of bian Shi was measured by infrared spectrometer and compared with the standard infrared spectrum curve of Sibin pumice.

3. Comprehensive mechanical parameter method. Various dynamic, static, elastic and inelastic mechanical parameters of bian stone were measured and compared with the standard mechanical parameters of Sibin pumice. Professor Geng Naiguang, an expert in rock physics at the Institute of Geophysics, Seismological Bureau of China, published the standard thin polarization micrograph, standard infrared spectrum curve and standard mechanical parameters of Spence pumice in his monograph "New Bian Shi Therapy". Any Bian Shi enterprise responsible to its customers can test their products according to these standard materials.

Identification method of true and false bian stone II. Correct method to distinguish true and false bian stone.

Microwave ovens use high-frequency alternating electromagnetic fields to generate eddy currents inside objects, and then heat the objects through the thermal effect of current. The temperature rise of the object in the microwave oven reflects the conductivity of the object to some extent.

The temperature of an object with high conductivity increases, while that of an object with low conductivity decreases. The electrical conductivity of Sibin pumice is not high in rocks. Its electrical conductivity is slightly higher than dolomite and marble, similar to granite and limestone, and lower than gabbro, basalt and sandstone. Therefore, the microwave oven can't be used to identify the authenticity of pumice in Sibin.

Some people claim that they have "special functions", and as long as they make great efforts, they can distinguish the authenticity of Spencer's pumice. This statement not only denies the scientific detection method of Spence pumice, but also denies that the search and discovery of gems must rely on modern technology. Imagine, if there really was such a "master" with miraculous powers, you wouldn't need time-consuming and laborious scientific experiments to find a good stone.

As long as you respectfully invite this "master" to make contributions in the wild, you can know which mountain this jade is on. If you try harder, you will know which stone is the best on the mountain, and it will be inconvenient to take it when you arrive. At present, the pumice resources in Sibin County are not sufficient. If someone can find more resources through hard work, it will also be a great contribution to the cause of Bian Shi. In fact, the discovery and identification of Bianju gems depend on modern science and technology.

People who have frequent contact with Sibin pumice have a certain perceptual knowledge of Sibin pumice. This experience is very valuable. It can be said that the authenticity of Spence pumice is insufficient, which has a certain role in identifying fakes. For Bian Shi enterprises, it is not easy to ensure that more than 80% of the products are authentic Sibin pumice if they rely on experience to test their products. To achieve qualified products, we must rely on scientific testing, not experience.

However, experience often plays an important role in the process of distinguishing fakes. Because most of the fakes in Bian Shi are not forged at a high level, you can tell by experience. The counterfeiters usually target people who have never seen Spine's pumice. People who have been exposed to pumice in Sibin, especially doctors who treat pumice patients in Sibin every day, can identify these fakes with their hands, at least they feel suspicious and won't buy them. The handle of Sibin pumice is: astringent, smooth, soft and hard, warm and cool. For a few fakes with a high level of counterfeiting, they can only be identified through scientific detection.
