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.

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 the jade bracelet, there was a clear difference between fluorescent reaction and reflective reaction. ** 1. Phorescent reaction ** 1. ** Cause ** - It was related to the handling of the jade. After the impurities were removed by acid washing, the B and C grade jade would be "changed" with dyeing agents and gelatins. These processed jadeites contained fluorescent agents and other substances, which would have a fluorescent reaction under the illumination of purple light. For example, jadeite dyed with glue would have a very obvious fluorescent reaction under the purple light. Even after turning off the purple light, one could see that its surface emitted a pale yellow fluorescent light. - In the case of a local fluorescent reaction, for example, some white bracelets had no fluorescent reaction under the illumination of purple light, but there was a fluorescent reaction in one or several parts. This was caused by the merchants adding green paint and colloid to the green part of the bracelet in order to highlight the green color. 2. ** Performance characteristics ** - It was a phenomenon produced under specific violet light. Under the illumination of a purple light, the jade would have a different luminous reaction from the normal state. For example, it would show fluorescence, which was generally related to the artificial treatment of the jade. Under normal circumstances (without the addition of fluorescent agents, etc.), natural jade would not have such a reaction under the illumination of a violet light. ** Two, Reflecting Light ** 1. ** Cause ** - For white jade that was thicker, it would emit purple light under the illumination of the purple light. This was not because of the fluorescent reaction, but because white jade was more reflective. In addition, the purple light itself was purple, and when it shone on this kind of jade, it would emit purple light. This was the reflection effect of its own structure and physical properties on light. 2. ** Performance characteristics ** - Reflection was more of a simple reflection of external light (such as the light emitted by a purple lamp). It did not involve the fluorescent material inside the jade. It was mainly caused by the physical properties of the jade itself (such as surface smoothness, crystal structure, etc.) affecting the reflection of light. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Under normal circumstances, A-grade jade would not have any fluorescent reaction under the purple light. However, there were special circumstances. Most jadeites would use polishing powder and wax boiling processes in the processing process, especially the jadeite that had just been processed. It was difficult to completely clean the gully corners carved on the pendant. There were often polishing powder and wax residue on the surface of the bracelet, which would form a fluorescent reaction under the purple light. There were also a few jades that contained more impurities. Some of the impurities might be sensitive to the purple light and would also produce a fluorescent reaction. However, the intensity of the fluorescence was different. However, these situations did not affect the attributes of the jade. Therefore, it was not accurate to determine that the jade bracelet was not an A-grade item just based on the fluorescent reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the jade was very old, the fluorescent jade would be more expensive because the crystal particles were arranged neatly and could be used as a flat theme. With this premise, it was equivalent to having a ticket to the top auction house. However, it was important to note that fluorescence and glue would not appear on a piece of jade at the same time. The fluorescence was cold, which reflected the hardness, and the glue was oil, which reflected the flexibility. Moreover, fluorescence was a visual optical phenomenon. To achieve this effect, the jade must be very old, which meant that the crystal particles were very small. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
Reading a novel might cause a physical reaction, but an overreaction could cause harm to the body. If you keep reading novels, your eyes might get tired and cause headaches, dry eyes, and other uncomfortable symptoms. If you are addicted to novels, you may be distracted and cause your body and brain to lack exercise, increasing the risk of developing nervous system diseases. In addition, reading too many novels could lead to gastric acid repulsion, indigestion, insomnia, and other health problems. Therefore, it is recommended to limit the reading time to maintain good health.
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>
Some fluorescent agents may cause allergic reactions in some people, and contact with polished jade bracelets containing fluorescent agents may cause skin itching, redness, rashes, and other uncomfortable feelings. However, the possibility of the fluorescent agent accumulating in the human body was small, because in most cases, it was added to the surface of the jade, and it was not easy to penetrate the skin into the body. From a scientific point of view, the fluorescent minerals in the jade bracelet usually did not have a direct harmful effect on the human body. The fluorescent reaction would only occur under specific light. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
In jadeite, there were two types of fluorescent light. If it was natural jade, it was an optical effect that would appear when the water was good. It was a layer of soft white light floating on the surface of the jade when the light changed. In this case, the fluorescence often indicated that the jade quality was better. However, if there was a fluorescent reaction under the illumination of a purple light, it might be fake jade, because the jade would be stained with fluorescent agent during the process of forgery. However, it should also be noted that natural jade may also have a fluorescent reaction due to the residue of polishing powder in the polishing step. There was no problem with the jade itself. Therefore, it was not possible to judge the quality of jade based solely on whether it was fluorescent or not. It needed to be judged comprehensively. The novel "Ledge" is equally exciting.

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>
The types of jade that were fluorescent were jade, bolivian jade, and ice jade. Emerald often appeared dark green or apple green and was very translucent. It would show a bright green glow under the violet light. The colors of emerald varied from light green to dark green, and often showed a rich light blue tone. Under the violet light, it would show a strong blue-green fluorescence. The color of ice jade often showed a cold and arrogant green or warm yellow tone. Under the violet light, its fluorescence was strong and uniform, radiating a bright green light. In addition, when the jade was well watered and absorbed the essence of heaven and earth, the light reflected from the bottom was also called fluorescence. The best way to reflect fluorescence was the curved surface. The curved surface at the bottom of the egg surface or the jade was watered would reflect fluorescence. However, the fluorescence of materials that were not planted enough would be divided into strong and weak fluorescence, which could be divided into weak fluorescence, strong fluorescence, and extremely strong fluorescence. There was also a situation where the jade used polishing powder residue containing fluorescent agent in the polishing process. This situation was not acid washing and glue dyeing, but after polishing, the colored polishing powder was sealed with wax without washing. Such jade would also have a fluorescent reaction and could be issued an A-grade certificate. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
