Workers can use saturated brine to easily determine the true and false beeswax: true beeswax will float on the surface due to its low density.
The staff used the mobile phone's flashlight to illuminate the internal structure of the product. The bubble in the product can be judged to be glass.
On the occasion of the March 15th, in order to help the public understand the consumption, the Morning News cooperated with the Autonomous Region Product Quality Supervision and Inspection Institute, Xinjiang Metrology and Testing Institute, and the Food and Drug Inspection Institute of the Autonomous Region to carry out the “3·15 Rights Testing Office†activities. Publicly ask for clues to consumers. The press conference will bring the products provided by consumers into the testing room for testing and identification, and help the consumers to identify the pros and cons by the authoritative testing of the laboratory.
I spent three or four thousand yuan to buy two Hetian jade bracelets and a honey wax pendant from the exhibition. I don't know if it is true or not. Recently, Chen Mei, a consumer from Urumqi, came to participate in the “3·15 Rights Protection Room†of the newspaper, and wanted to send the three “babies†she had picked up from the exhibition to the testing room for identification.
It is reported that these treasures are sold at a jewelry jewellery store. "The honey wax pendant is priced at more than 11,000 yuan and looks very beautiful. The two Hetian jade bracelets are also oily and fat. Can not withstand the repeated price reductions of merchants. I bought it when my brain was hot." Chen Mei recalled.
On March 3, the reporter took these "babies" and went to the national Hetian jade product quality supervision and inspection center. All the products were identified as fakes. So how do consumers identify themselves and the true and false of Hetian jade? Experts from the National Hetian Jade Testing Center demonstrated through small experiments and instruments.
The fake beeswax was originally "plastic imitation"
How does the national Hetian jade inspection center simply identify the true and false beeswax? The reporter saw the quality inspector Chang Yayun grabbed a beeswax and put it in the salt water.
Suddenly, a seemingly inconspicuous milky white wax floated up. Chen Mei’s yellow chanterelle wax pendant sank to the bottom, and there were several smaller beeswax materials and a beaded pendant. Sink into the water.
“100% of the sinking into the bottom is fake. Many of these 'beeswax' that sink into the bottom are made of plastic. The density of plastic is larger than that of beeswax. It is placed in saturated brine and quickly sinks into the bottom. Chang Yayun, a quality inspector at the National Hetian Jade Product Quality Supervision and Inspection Center, said that the identification principle is: amber (opaque amber called beeswax) density between 1.05-1.10, saturated brine at 1:4 (salt: water) Amber, lightweight plastics and resins can all float, and ordinary plastic, glass, acrylic and bakelite sink.
So what proportion of saturated brine is blended? How strong is it? I saw Chang Yayun slowly pouring salt into a bowl of clear water, and stirring with chopsticks, stirring until the poured salt particles did not melt, and saturated brine was made.
According to reports, due to the high price of beeswax, in recent years, counterfeiting methods have emerged in an endless stream, and plastic counterfeiting is more common. The use of saturated brine to test the true and false beeswax can generally identify plastic imitations. However, some fake beeswax with superb falsification techniques still need laboratory equipment to distinguish them.
Mobile phone photos and Tian Yuzheng fake
Glass or other jade is often used in the market to imitate Hetian jade. How can consumers simply identify Hetian jade? Chang Yayun is able to prepare two things: one is a mobile phone, and the other is a blade.
Among the four bracelets placed on the scene, Chang Asian Games picked up the mobile phone flashlight one by one, and saw a "Hita Biyu" with obvious bubbles under the light. "Hetian jade bracelets and pendants with bubbles are all glass imitation. Chang Yayun said that if the internal structure of Hetian jade is very clean under the illumination of mobile phones, be careful not to have any flaws.
It is even easier to identify with a blade. Hetian jade has a relatively high Mohs hardness of about 6.5 degrees, while the hardness of the blade is generally 5.5 degrees, which is lower than Hetian jade. If the blade can be used to mark the inner ring of the jade bracelet, it is not Hetian jade.
Chang Asian Games reminds: Consumers should buy Hetian jade through formal channels, and don't trust the roadside stalls. One point for the price of goods, the price is too cheap for Hetian jade, fake counterfeit.
If consumers buy Hetian jade, which is difficult to distinguish between true and false, they can also go to the National Hetian Jade Product Quality Supervision and Inspection Center for testing.
The reporter saw at the scene that the staff used an infrared spectrum analyzer to identify two identical bracelets. One is a real sheep fat jade, and the other is a fake sheep fat jade. The infrared maps of the two are completely different. The staff can identify the true and false by 5 seconds.
