In jadeite related concepts," fluorescence " and " lustre " were actually the same concept. It referred to an optical phenomenon that appeared in jadeite that was old, had small crystal particles, sufficient water head, and high clarity. When light passed through the jade, its outline would reflect a bright line. When the jade was gently shaken under natural light, a soft white light could be seen. From a physical point of view, it was because of the high degree of clarity of the jade. When the light was transmitted to the polished surface, the surface micro-ripples produced reflected light to form reflective spots. A portion of the light entered the jade, and before the internal and air media were converted, the surface micro-ripples of the jade produced a strong diffuse reflection. Together with the refraction between the jadeite grains, they formed a hazy white light. This phenomenon was more common at the edge of the carved outline or in the circular area. Usually, only some jadeites would have this phenomenon. The price of fluorescent jadeite was often higher. 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.

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!
The jade with fluorescent reaction was likely to have been processed, but it could not be said that the jade with fluorescent reaction was not authentic. In the past, since the jade was mostly filled with organic resin such as epoxy after being pickled, it would have a fluorescent reaction under the purple light. However, the technology of forgery had changed. It was possible for the fake goods to not contain fluorescent agents, so even if there was no fluorescent reaction, it could not be determined that it was fake goods. Moreover, during the processing of natural jadeite, such as the gully corners of the pendant carving and the surface of the bracelet, there may be polishing powder and wax residue. These substances will have a fluorescent reaction under the purple light. There are very few jadeites with more impurities. The impurities may be sensitive to the purple light and will also produce a fluorescent reaction, but these jadeites are still A-grade. In addition, if one used dyed chalcedony, dyed glass, Dulong jade, or azure jelly to pass off as jade, there would be no reaction under the purple light. Therefore, the purple light detection was only an auxiliary method. It was not possible to determine the authenticity of the jade based on the fluorescent reaction alone.

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 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!
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>
In web novels, the difference between spiritual jade and stone jade might be as follows: 1. Spirit jade was a kind of jade with spirituality. It usually had a mysterious power that could help cultivators improve their cultivation. As for stone jade, it was an ordinary jade stone with no special effects. 2. The quality of spiritual jade was more delicate than stone jade. It had a higher luster and a brighter color. The texture of stone jade was rough, the luster was low, and the color was dull. 3. Spiritual jade was usually formed from the spiritual energy of heaven and earth, and it was relatively rare. Stone jade, on the other hand, was made from ordinary stones that had been processed, and there were more of them. 4. The price of spiritual jade was much higher than that of stone jade because it had mysterious power and special effects. The price of stone jade was relatively cheap because it was just an ordinary jade.

There were the following differences between mountain and water jade: 1. [Mining environment: Mountain materials are mined from mountains, while water materials are mined from water.] 2. ** In terms of texture, the mountain material is rough, uneven, and loose in structure, while the water material is fine, even, and compact in structure. 3. ** Color performance **: The color of the mountain material is relatively light and the green color is darker; the color of the water material is full and the green color is brighter. 4. ** Appearance characteristics **: The surface of the mountain material is rough, while the surface of the water material is smooth. 5. ** Grease Glow **: The luster of mountain materials is weak, while the luster of water materials is strong. 6. ** Processing technology **: The processing technology of mountain materials is more complicated and requires fine carving. The processing technology of water materials is simpler and easier to carve. 7. ** Price and Mining Difficulty **: Water materials are relatively expensive and difficult to mine; mountain materials are relatively cheap and easy to mine.

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!
