Does the coral string have a 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. Read more exciting novels for free
agate 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>
The bracelet has a fluorescent reaction
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>
Why does the jade have a 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!
What is the difference between the fluorescent reaction and the reflective reaction of the jade bracelet?
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>
The jade bracelet had a fluorescent reaction and was tested to be a good
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>
Analysis of the principle of fluorescent reaction method for identifying jadeite beads
The fluorescent reaction method for identifying jade beads was based on the principles of minerals and light. Jadeite was mainly composed of minerals, and the trace elements contained in it, such as calcium, could affect its fluorescence reaction. From an optical point of view, when the violet light such as a purple lamp shone on the jade bead, energy transfer would occur. Taking the element of Chromiumas an example, the purple light stimulated the element of Chromiumand caused its electrons to jump from a low energy level to a high energy level. Then, when it returned to a low energy level, it released a photon of a specific energy, producing a specific color of fluorescence, such as red fluorescence. The Lanthanum element in the jade would release a specific energy when the energy level transition occurred under the effect of the purple light, resulting in an emerald green fluorescence. From a mineral perspective, the trace elements such as mercury and iron contained in jadeite minerals would affect its color and fluorescence properties. The geological environment and origin of jadeite deposits in different regions were different, resulting in differences in the types and contents of trace elements, which led to slight differences in their fluorescence reactions. In addition, natural jade and processed jade had different fluorescent reactions. Real jadeite contains a certain amount of specific elements, and it will show a strong green fluorescence under the violet light (such as when the calcium meta-acid works). Fake jadeite is often made by dyeing and other means, and usually has no fluorescence or weak fluorescence. For example, jade soaked in wax would produce a blue-white fluorescent reaction; jade washed with acid and then injected with glue would produce a blue-white or green-white fluorescent reaction; if it showed a pinkish blue fluorescent reaction under long-wave ultraviolet-light, then this jade was likely to be a b grade jade, and the fluorescent part was likely to be injected with resin. However, the fluorescent reaction was not the only basis for determining the authenticity of jade. It was also necessary to consider its color, texture, clarity, hardness, and other characteristics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Which is more expensive, the fluorescent jade or the fluorescent jade?
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!

Is the fluorescent jade good?
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.

The night is waning, slightly fluorescent
The night sky was waning and the faint glow was the lyrics of the song " Night." This song was originally sung by Teresa Teng, and later other singers covered it. The lyrics described the night scene and hinted at a romantic atmosphere. The specific content and meaning of the song could only be understood by referring to the complete lyrics.
