How to judge the old and new jade materials

There was no simple answer to this question. It depended on one's personal preferences and the purpose of collecting. From the perspective of texture, the old material had undergone weathering, river impact, etc., so its structure was relatively compact, and its quality and color were basically better. It was a secondary ore formed by the second time, while the new material was a primary ore, and the texture was generally slightly different. The old material had been underground for a long time. Its foundation was fine and its surface was shiny. The new material's foundation was relatively rough. Moreover, the new material might turn yellow if worn for a long time. From the perspective of appearance and collection value, if you pay attention to historical inheritance and cultural accumulation, old jade is a better choice, which can make people feel the accumulation of time. If you pay more attention to quality and appearance, new jade may be more in line with taste. It is usually more dazzling and has higher clarity and purity. The novel "Ledge" is equally exciting.

There was a big difference in the price between new and old jade. New jadeite was a raw material that had not been naturally oxided for a long time after being mined from the mine. Its texture was relatively coarse, its color was light, and it was easy to fade. It lacked historical and cultural value. Old jadeite was formed after a long period of natural oxidization, weathering, and other geological processes. It had a certain historical and cultural value of jadeite raw materials. In most cases, the texture was fine, the water was sufficient, and the color was stable. These factors made the value of old jade higher, while the value of new jade was relatively lower.

There was no simple answer to this question, because each had its own merits, depending on one's personal preferences and collection purposes. If one paid attention to the inheritance of history and the accumulation of culture, the old material jade was a better choice. It could make people feel the accumulation of time and the inheritance of civilization. The old material jade had been eliminated and screened by nature again. For example, the old pit material jade had a compact texture, a finer structure, a higher degree of clarity, a fine and tough texture, a soft color, and a sufficient water head. If one paid more attention to the quality and appearance of the jade, the new jade might be more suitable for the taste. They were usually more dazzling and had higher clarity and purity. The new material jade was the original ore jade. It had not undergone the elimination and screening of nature again. Its structure was relatively coarse, and its texture and clarity were relatively poor. In short, whether it was old jade or new jade, they all had their own characteristics and irreplaceable value. When choosing, one should weigh it according to one's personal preferences and the purpose of collecting it, so as to better experience the fun brought by jade and the satisfaction of collecting it.

To determine whether the jade was pickled or not, one could start from the following aspects: 1. ** Acid Erosion Web Pattern **: Observe whether the jade has an irregular grid-like acid erosion web pattern and whether there are impurities inside. 2. ** Color **: The color of pickled jade is dull and dull. 3. ** Sound **: The sound of pickled jade is dull, while the sound of natural jade is crisp and pleasant. 4. ** Weight **: The jade gives people a comfortable feeling of weight, but the density of the pickled jade will change, and the structure will not be as compact as before, so the weight will be reduced. 5. ** Flaw **: The purpose of acid washing is to remove impurities, so acid washing jade will give people a flawless sense of perfection. You can use a magnifying glass to observe carefully. 6. ** Gloss **: Acid washing will make the surface of the jade potholes, loose structure, and produce diffuse reflection when the light shines on it, without the glass luster of natural jade after polishing. 7. ** Translucency and color **: pickled jade may have unnatural clarity, and the color is too uniform and bright. 8. ** fluorescence reaction **: When illuminated by a purple light, the jade that was pickled and glued would have a yellow-green or other color fluorescence reaction. However, some natural jadeites that were soaked in wax had a weak fluorescence reaction, and some of the resin-filled jadeites that were pickled and glued did not produce a fluorescence reaction. Therefore, this method is only for reference. 9. ** Electrostatic friction **: If the jade contains resin (pickled rubber-injected jade contains resin), the friction will generate static electricity to absorb small paper scraps, but it is not necessarily natural jade that cannot absorb paper scraps. 10. ** Soak in hot water **: Soak the jadeite in hot water. The jadeite that will fade after being heated may be the jadeite that has been pickled and glued. Natural jadeite will not fade. 11. ** Magnifying Glass Observation **: If you observe under a magnifying glass, you may see traces of pickled jade fillings. The novel "Ledge" is equally exciting.

The following methods could be used to determine whether a jade was real or fake: 1. ** Color distinction **: The color of natural jade is natural and evenly distributed; the color of dyed jade is gorgeous and not natural enough. 2. ** Touch **: Different jade density has different hand feel. For example, Hetian jade has a higher density, so it will feel heavier. Holding it in your hand will give you a cold and slippery feeling. If you push it with your hand, you will feel that the oil is pushed away and there is a sense of resistance. Fake jade does not have these characteristics. 3. ** Light observation **: Under the light or sunlight, the internal structure of natural jade is naturally orderly; artificial imitation jade has obvious artificial traces, and there are even air bubbles inside. When observing the texture of the jade, if it is uniform and transparent and has a good luster, it may be real Hetian jade; if it is very rough and the interior is vague and opaque, it is mostly fake Hetian jade. 4. [Distinguish by sound: When jade is knocked against each other, the sound of natural jade is clear and melodious, while the sound of fake jade is muffled.] One could hang the jade in the air with a rope and then use another jade to gently knock it to judge. 5. ** Judgment of special circumstances **: - For the fake materials (such as glass imitation jade, resin imitation beeswax, etc.), you can observe and compare the texture and texture of the jade, and weigh it by hand. Jade made of glass was too transparent and perfect, without any natural traces, and was lighter than jade, while jade made of resin and plastic could not compare to real jade in terms of weight and hardness. - For fake jade made from inferior real jade, one could look at the texture, structure, and color. For example, the color and texture of B grade jade processed by acid corrosion were not as natural as natural jade. There might be grid-like patterns in the structure that natural jade did not have.

To determine whether the jade was cracked or not, one could start from the following aspects: 1. ** Color **: The stone patterns are generally white or milky white, while the cracks are generally colorless or white. However, it is difficult to distinguish them from the color. 2. In terms of touch, the stone patterns were "visible but not touchable", and there was no strange feeling when touched with the hand. The cracks were damage from the inside out, and the obvious texture could be felt when scratched and touched with the nail. 3. ** Light up and observe **: You can use a flashlight to observe the cracks and distinguish the "crack" and "growth pattern" of the jade. Do not use too strong light during observation. 4. ** Magnifying Glass Observation (auxiliary method)**: If the above methods are still unable to determine, you can use a 10x magnifying glass to observe. Under a 10x magnifying glass, the crack was an open structure without any filling, while the stone pattern was a thread-like structure similar to bread.

" Old jade " was a relatively broad concept. It usually referred to jade that was older, and its focus was on the age of the jade. For example, antique old jade might cover various types of jade, including Xiuyu, Hetian jade, and other different types of ancient jade. These jade may have a certain historical and cultural value due to their age. Old Pit Jade had a different meaning. Taking Hetian jade as an example, from the perspective of mining time, the jade mined in the old Kuangqu is the old pit jade; from the perspective of composition and other characteristics, the Qinghai material with higher tremolite content and closer to the traditional Hetian jade can be called the old pit material. Among the jadeites, the jadeite gravel that had been mechanically weathered and transported to the river valley and riverbed was called "old pit jade" or "young material". In general," old jade " emphasized the age of the jade, while " old pit jade " focused more on the source of the jade or the specific composition and formation conditions.

In jadeite, the fine texture of the meat was an important characteristic, but it was not the only criterion. Judging from the internal structure of the jade, it meant that the crystal particles were fine and tightly bonded to each other, which usually showed a delicate state of meat. For example, the crystal particles had small gaps and a compact structure, which often made the texture of the jade look more delicate. This was also one of the characteristics of the old jade. However, to determine whether the jade was old or not, other factors needed to be combined. For example, the clarity of the jade was also an important consideration. The clarity of the old kind of jade was often better. The content of impurities in the jade would also affect the judgment of the old kind of jade. The jadeite content of the old kind of jade reached the theoretical content, and there were very few impurities. If there were more impurities, it would make the jade become new. Even if the meat was fine, it was difficult to judge the old kind of jade when there were too many impurities. In addition, from the broad concept of jade species, even if there were cases where the meat was fine and delicate in the species named after certain characteristics such as ice species and glutinous species, it might not be determined to be old due to other factors when comparing within the species.

The old jade was a type of jade. Its material was a type of metamorphosed rock, and its main component was a meta-mineral. After experiencing high temperature and high pressure, it formed a unique jade structure. Observing it under a microscope, it showed a fiber structure, which made it have high toughness and hardness. At the same time, the material contained a certain amount of moisture and grease. These moisture and grease formed a protective film on the surface of the jade, giving it an oily appearance and feel. The color of the Old Oil Jade was unique. It was a deep and full green. This green was different from the common emerald green or tender green. It was more like a deep green that had been baptized by time. It had a greasy feeling and would emit a greasy luster under the sun. The color was generally translucent. The texture was warm and delicate, and it felt smooth. The novel "Listening to the Rain in Green Bamboo and Watching the Egrets" is equally wonderful. Everyone is welcome to click and read it!
