A post titled "Look at how the jade bracelet slowly kills you" has been widely spread on the Internet recently. The post tells the "terror" production process of the jade jade bracelet, and said that "the flower has bought a huge amount." Baby, I don’t know if it is a highly carcinogenic 'baby' that will release toxins and radioactive elements for a long time. This has made many consumers who are fond of the emeralds uneasy.

Many netizens said that they like jade but don't know jade. I hope that when I buy it, I will learn from experts and how to distinguish between true and false jade. In this issue, we invite industry insiders and experts in the gemological identification to answer questions.

"High carcinogenic" production is actually B cargo processing technology

The net sticker "Look at how the jade bracelet slowly kills you" said that before making the jade jade bracelet, a pile of water, no bottom, no color stone material is soaked with a strong acid and a chemical containing a large amount of radioactive elements. Month (the process is called "washing the bottom"), then artificially add color to the washed stone, and then enter the vacuum high-pressure injection machine, injection with highly toxic chemicals, a few days later, the semi-finished product is released, the original The wool has already had a color of water. "The general market price is called 70,000 and 80,000, and the counter price will be sold."

The jade jade bracelet is a high-end decoration favored by many people, and this post has made many consumers feel uneasy. Zhang En, an associate professor of the Department of Earth Sciences at Sun Yat-Sen University and a gemologist at the China Gemstone Association, said that from the content of the net post, it is actually about the artificial processing of jade B goods.

Zhang En said that this process is not new and has appeared and been widely used in the 1990s. The raw materials used in B cargo processing are natural jade stones, but the texture is not good or contains more impurities. It is commonly called “poor head”, instead of the general stone used in the net post, and other jade materials use this treatment. The process is relatively rare, because not all jade materials can withstand the soaking of strong acid and alkali, "For example, marble can be corroded with weak acid." Plus jade is more expensive, higher grade in jade, so the process is more Used for the treatment of jade jade.

"In an inappropriate example, this process is equivalent to plastic surgery such as 'cutting double eyelids' and 'high noses' for jade. Generally speaking, it is normal to give jade beauty." Well said.

Chemical soak does not release toxins

According to the net post, when washing the jade jade bracelet, "sweet for half a month with strong acid and a chemical containing a lot of radioactive elements", which leads to the jade bracelet "will release toxins and radioactive elements for a long time." In this regard, Zhang En said that this statement is alarmist.

Zhang En said that in the treatment of Jade B, it will indeed be soaked with strong acid or alkali preparations, and it will generally be carried out under heating conditions. The purpose of this is to corrode and dissolve the jadeite. Contains the impurity components, and does not use the so-called "radioactive element-containing chemical", because "not at all", the jadeite after soaking with strong acid and alkali will be washed and dried, and will not be "long-term release." toxin".

As for the "re-injection of highly toxic chemicals" after washing the bottom, Zhang En said that the structure of the jade stone washed with strong acid is loose, so it is necessary to fill the crack after the acid etching. The common method is to use the vacuum negative pressure method to inject the glue. The material used for filling glue is epoxy. "This is not very toxic, of course, unless you eat it in your stomach."

"The jade jade bracelet processed in this way is harmless to the human body, but the texture is not so good. It is not as natural as the jadeite. The more people wear it, the more likely they are. After a long time, there may be problems such as cracks." Zhang En said.
