The following anti-counterfeit measures require fluorescent reaction:

The fluorescent reaction of agate was more complicated and required a comprehensive judgment of many factors. When identifying the relationship between the color of agate and the fluorescence reaction, it could be compared to the purple light reaction of the gray skin of ancient jade. If there was a reaction to the color of the agate under the purple light, it was necessary to observe whether the agate plastids under the color had corresponding changes. For example, whether the erosion in the place with heavy color had a corresponding depth, because the color of the agate also needed to be distributed naturally and layered. If the depth of the color was scattered and contrasted with each other, the fluorescent reaction could be used as evidence. If it was only on the surface, the internal agate plastids did not change significantly, and could not echo with the color, even if there was a fluorescent reaction, it should not be used as a basis for judgment alone. In addition, different colors of agate had different fluorescent reactions under violet light. For example, red or purple agate might have fluorescent reactions under violet light. This may be because the violet light stimulated the fluorescent substances inside the agate, which may be rich in specific minerals. In the market, natural agate and imitations may have fluorescent reactions, so the fluorescent reaction to identify the color of agate could not only be based on whether there was fluorescence, but also combined with the color, texture, shape, weight, hardness and other factors of agate to make a comprehensive judgment. Moreover, agate fluorescence reaction was a complex physical and chemical reaction. If you want to accurately determine, you may need a professional laboratory to test and analyze. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There could be many reasons why the bracelet had a fluorescent reaction. If it was a jade bracelet, the fluorescent reaction did not necessarily mean that it was a B grade jade (pickled, glued, or dyed jade). In the early days, B grade jade would have a fluorescent reaction under purple light because it was filled with epoxy after being pickled. However, now that the forgery technology had improved, the B grade jade might not contain fluorescent agents and would not have a fluorescent reaction. At the same time, if the bracelet was made of dyed chalcedony, dyed glass, Lone Dragon Jade, or azure jelly, which were fake jadeites, there might not be any reaction under the purple light. In addition, during the processing of natural jadeite, the polishing powder and wax boiling process may cause a fluorescent reaction, especially for jadeite that has just been processed. When there are polishing powder and wax residue on the surface of the pendant carving, there will be a fluorescent reaction under the purple light. There are also a few jadeites that contain more impurities. Some impurities may be sensitive to the purple light and produce different fluorescent reactions, but it does not affect the quality of the jade. Therefore, the quality or authenticity of the bracelet could not be determined simply based on the fluorescent reaction of the plaque. It had to be judged by a combination of various factors. If an accurate result was needed, it was recommended to seek the identification of a professional appraisal agency. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

At present, there was no scientific evidence that the fluorescent reaction of jade was harmful to the human body. Jade was usually worn on the body as an ornament. It would not come into direct contact with the skin or be ingested by the human body, so the fluorescent reaction had no direct effect on the body. However, if there were any chemical coating or treatment agents on the emerald gemstone, these could have negative effects on the human body, but this had nothing to do with the fluorescent reaction.

If it was a natural coral string, some of them would have a fluorescent reaction. For example, the ice red coral would emit green fluorescence under violet light because it contained a certain quartzite component, and the quartzite would have a fluorescent reaction under violet light. Shallow corals that grew in the Red Sea were green. At a depth of 50 - 60 meters, some corals appeared yellow, orange, or red, which provided light for the growth of symbiotic algae and was also a fluorescent reaction. If the coral string was polished and not cleaned thoroughly during the production process, the residual brightening agent, polishing powder, and other chemicals on the surface would also show a fluorescent reaction under the purple light. This situation was more likely to occur on coral jade carvings because the surface marks were easy to hide these chemicals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The fluorescent reaction of jade could be caused by many reasons. First of all, if it was B, C, or B + C jade, it would be pickled, glued, dyed, etc. during the production process. The chemical substances filled in it might produce a fluorescent reaction under the illumination of the purple light. This was because the internal structure of these processed jadeites had been changed and contained substances that would react under violet light. Secondly, even if it was natural jade, if colored polishing powder was used in the polishing process and sealed with wax without thorough cleaning, the residue of the polishing powder would also cause a fluorescent reaction. Although this kind of jade was A natural jade, it was artificially enhanced, so its value was lower than that of the raw natural jade. Moreover, after wearing it for a long time, as the wax on the surface peeled off, the color would become lighter and uglier. In addition, if the natural jade had been waxed, and the structure was not tight enough, the wax would penetrate too much, and the fluorescent reaction under the purple light would be relatively strong. There were also some white jades that had a faint orange glow. The last thing to note was that some new types of fake jadeite were now filled with non-fluorescent substances and stains. Even if it was fake, there might be no fluorescent reaction under the purple light. Therefore, the purple light detection of jadeite had certain limitations. It could not be completely relied on to determine the authenticity of jadeite. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!

In jadeite," fluorescent reaction " had a specific meaning. In the early days of the counterfeit goods on the market, due to the limited technology, the pickled jade was mostly filled with epoxide-based resin. This organic resin would stimulate visible light under a purple light, which was the fluorescent reaction. The jade that was dipped in wax would show blue-white fluorescence under the fluorescent light, and the jade that was injected with glue after artificial strong acid rinsing would show blue-white or green-white fluorescence under the fluorescent light. Generally speaking, jadeite with fluorescent reaction was often treated with chemicals and not natural A-grade jade. However, there were special circumstances. For example, natural jadeite used polishing powder during the polishing step. When the polishing powder remained on the surface of the jadeite, it might also cause a fluorescent reaction. Moreover, fakes were also being upgraded. Some of the new B + C fakes were filled with non-fluorescent substances and stains. They did not react under the purple light and were difficult to distinguish from natural jade. Therefore, the fluorescent reaction could not be used as the only basis to determine the authenticity of jade. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
