How to judge the authenticity of jade

To identify the authenticity of jade, one could start from the following aspects: ** 1. Color ** 1. ** Natural jade color characteristics ** - The color of natural jade was naturally formed. The color was natural and evenly distributed. For example, Hetian jade, a high-quality white should be warm and shiny, not a dazzling cold white, but a soft white with a "fat feeling." If a piece of jade was as white as a piece of paper, it might be a "fake white jade" that had been treated with whiteness. - For jade and other jades, if the color was too thick, stiff, and not as natural as the color of natural jade, it might have been processed or forged. 2. ** Fake Jade Color Specialties ** - Fake jade was dry, dull, and lifeless. It was like jade that was made of glass. Its color was often too transparent and perfect, and it did not have the natural feeling of natural jade. ** 2. Hand feeling ** 1. ** True Jade Touch ** - True jade had a certain density, and holding it in his hand would give him a corresponding feeling. For example, Hetian jade had a high density. When held in one's hand, it would have a heavy feeling, and it would have a slight cool touch. It would have a cold and warm feeling. 2. ** Fake Jade Touch ** - Fake jade might seem light when held, like a glass imitation of jade. It felt rough and almost did not have the cold feeling of real jade. ** 3. In terms of structure ** 1. ** Observing the structure of the real jade with light ** - For Hetian jade, you can use a small flashlight or a mobile phone flashlight to observe the jade. There was a fiber interwoven structure inside the real Hetian jade, like layers of fat fibers. - Different jades had their own unique natural structure when observed by light. For example, if the jade was processed by acid corrosion (B grade jade), some grid-like patterns that were not found in natural jade might be seen in the structure. 2. ** Fake Jade's structural characteristics ** - Inferior fake jade was either too transparent or the fiber structure could not be seen at all (for jade with fiber structure characteristics like Hetian jade). ** 4. Sound ** 1. ** True Jade's Voice Attribute ** - Good Hetian jade would produce a crisp echo when struck, especially the best seed material. When struck, one could hear a long and deep tone. As for the other jade pieces, they were hung up with thin threads and knocked lightly with a hard object. The sound of the real jade was crisp and pleasant, and the aftertaste was melodious. 2. ** Fake Jade's voice characteristics ** - The low-quality fake jade was mostly a dull "plastic sound" or a metal-like "hard sound". ** 5. Other special identification methods ** 1. ** Hetian Jade's Water Drop Test ** - The surface of Hetian jade was extremely dense and smooth. If a drop of water was dropped on its surface, the water drop would remain round and not spread easily. If it was a fake jade, the water droplets would disperse very quickly. 2. ** For the pore identification of Hetian Jade Seed Material (For Hetian Jade Seed Material)** - ** Pore shape and size **: The pores of the natural seed material are traces left by running water. They are small on the outside and large on the inside. They have a certain depth and are shaped like the pores on human skin. They are delicate and smooth to the touch. The pores of the sandblasted seed were large on the outside and small on the inside, showing the shape of an open trumpet. In the beginning, the pores of the sandblasted seed were rough and shallow, but after improvement, they were too small. - ** Direction and angle of erosion marks **: Natural seeds are formed by being washed in the river for a long time. The erosion angle of each position will change according to the shape of the original stone, and it looks smooth and natural. The sandblasting machine carried out a flat impact, and the angles of the pores were often the same. Even if the shape of the jade stone changed at the corner, the sandblasting marks remained the same, which seemed unnatural. - ** The relationship between the degree of pore exquisiteness and jade quality **: The finer the jade quality of Hetian seed material, the finer the pores. The pores of different parts of the natural seed material have significant differences. Even if the quality of the jade stone was poor, the pores might be processed to be extremely fine. The appearance of overly well-proportioned pores on the raw materials should be vigilant. - [Over-naturalness: The pores of the natural seed material are naturally formed in the water. The changes are smooth and natural. There are no traces of deliberate creation.] Although the sandblasting imitation seeds could be adjusted, the changes were step-by-step, and the details were often abrupt. - ** The relationship between the skin color and the pores: The skin color of the natural seed material and the pores are produced simultaneously, and it is difficult to distinguish the order. The surface skin color and the pores are integrated into one. Sandblasting imitation seeds were first sandblasted and then dyed. The skin color often floated above the pores, and sometimes there would be deposits in the potholes. 3. ** Hardness test (applicable to some jade)** - When the jade was slid across the glass, the glass would leave obvious scratches, but the jade itself would not leave any marks. However, this method was not suitable for all jade, and it might cause some damage to the jade, so it needed to be used with caution. The novel "Dream of Silk Fate" is equally exciting.

To determine the authenticity of the gold gilding, one could start from the following aspects: 1. ** Color **: The color of the real gilded gold is golden yellow. After being placed for a long time, the color will become dim, but the light reflected from it is soft and warm. The color of the fake gilded gold is too saturated and bright, lacking a natural feeling, and the light reflected from it is more dazzling. 2. ** Quality **: The real gilded products contain more copper, the metal copper used is purer, the weight is relatively heavy, and the thickness of the casting objects is larger; the objects made of fake gilded products are mostly made of alloy materials, the copper content is low, and the weight is not as heavy as the real gilded products. 3. ** In terms of smell **: Real gilded gold is usually gilded by fire, and there will be the smell of fireworks on the surface. If it is buried underground for a long time, you can smell the smell of mold. Fake gilded gold is a modern imitation, and it smells like chemical corrosion. 4. ** Observation of rust **: Most ancient gilded copper Buddha statues have rust. The rust can be dissolved with sulfuric acid or sulfuric acid in the laboratory. According to whether copper ions or impurity ions can be decomposed, it is determined whether it is rust or natural rust. 5. ** Check the gilded part **: Most of the real gilded parts are gilded in specific parts. For example, gilded plates only have a layer of gilded on the surface of the plate, but fake gilded parts are usually gilded on the entire metal part. 6. [Inscription Appraisal]: To identify the authenticity of an inscription, you can look at the font (the style of each period is different), the saber technique (good or bad, and whether it is natural), and also observe the old or new copper color of the words. In addition, you can check whether the content of the inscription conforms to the style of the era displayed by the Buddha statue (targeted at the inscriptions on the Buddha statue).

To determine the authenticity of the kindergarten game, one could start from the following aspects: From the perspective of children's autonomy, if the game is an activity that children voluntarily participate in, the child can decide how to play, what to play, and who to play with. For example, during the independent play time, the child can freely choose materials, playmates, and decide the way of play. On the other hand, if the teacher's will is the dominant factor, such as the teacher pre-arranging the child to play a fixed role and not allowing it to be changed, repeatedly rehearsing to achieve the effect of the "high-control" game, or a one-sided understanding of the child's autonomy and the game content and form do not match the characteristics of the child's age development, and there is no rule or development goal to reflect the "sheep" game, it is a pseudo-game. From the point of view of the purpose of the game, if the child's game has no external purpose and is only for the happiness brought by the game itself, such as the child simply playing building games, role-playing games, etc., this is a real game; If the game is carefully designed by adults and has sufficient intervention, with a utility purpose, such as a game set up just to show others or achieve a certain educational result, it is a fake game. From the perspective of the game process, real games pay attention to the process rather than the result. Children will tirelessly use different methods to do the same thing. In the process, children constantly challenge themselves. For example, in the game of building a slide, children constantly adjust the materials to make the slide more fun. If the game is mechanically repeated or the child quickly loses interest and lacks exploration, it may be a fake game. From the perspective of children's emotional experience, real games mainly allowed children to experience positive emotions such as joy, pride, satisfaction, etc. Although there would be tension when challenging or frustration when failing, these negative emotions would not be stronger and lasting than positive emotions, nor would they be stronger and lasting than negative emotions in utilitarian-based activities. If children experienced too much negative emotions in the game or the game could not bring the positive emotional experience that children should have, it might not be a real game. From the perspective of whether the game represented the child's existing experience, real games were activities for children to show their existing experience. When they encountered difficulties with insufficient experience, they would also explore and solve them based on their existing experience to obtain new experience. If the game was separated from the child's experience base and there was no space for exploration and experience expansion, it did not conform to the characteristics of real games. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Among the virtual simulation software for jewelry and jade identification mentioned at present, the infrared spectrum three-dimensional simulation software could be used for jade identification. It was based on the national standard," Gem and Jade Identification by infrared spectrum method ", which simulated the whole operation process of Thermo Fei Nicolete iS5. It also established a typical infrared spectrum library of gems and jade. Students could identify gems and jade through peak marking, amplification and other functions, including the identification of gem species, the distinction between natural and synthetic gems, and the identification of whether they had been artificially optimized. However, there was no mention of whether there was a generally applicable software that specialized in identifying the authenticity of jade. In actual jade identification, professional tools such as magnifying glasses to observe defective bubbles, infrared lamps to see if there was abnormal fluorescence, and spectrum analyzer were used. At the same time, there were professional official appraisers in the jade app to identify the quality of Hetian jade. Zhuang Jadeite established the GID Jadeite Laboratory to identify the origin of the jade. " Fairy Dream of Tang Shi: Fate of Peony " is equally wonderful. Everyone is welcome to click and read it!

The following are some ways to distinguish the authenticity of jade: ** 1. Distinguish by appearance ** 1. ** Look at the luster ** - Natural jadeite (Grade A) had a typical glass luster, looking bright and clear, while jadeite (Grade B, C, etc.) that had been injected with glue and bleached had a resin luster, dull luster, and even a wax texture, lacking in hardness. 2. ** Look at the structure ** - The color and base of the natural jade were natural and generous. The green color was like the distribution of tree roots or lumps, with clear and distinct contours. The color of the processed B grade jade was blurry and unclear. The color and base were like Chinese paintings, with spots, black spots, or floating fragments. Most of them showed this green on grayish-white or bean-green land. - Natural jadeite had a green nature, which was a kind of structure that was intertwined with fiber crystals and mottled crystals. One could see star-shaped, needle-shaped, or sheet-shaped shiny surfaces, also known as fly wings. The emerald nature of the A product was obvious, but the emerald nature of the B product might also be obvious when the degree of acid treatment was light, but if the degree of treatment was heavy, the emerald nature would be blurred. - Looking at it with a high-powered magnifying glass, the surface of Grade A was smooth and delicate. It could be seen that different mineral particles had subtle bumps and grain intersection patterns on the surface due to the difference in hardness. For inferior quality goods, the grooves caused by poor polishing usually only appeared in local areas, especially in the pits that were not easy to polish. The surface of the B goods was messy, and the lines were bent and straight. They were spiderweb-like and branch-like grooves. Due to the difference in hardness, there was an orange-peel-like structure on the surface. The more processed B goods had cracks on the surface. 3. ** Look at the color ** - The color of natural jadeite was uneven, with color roots. One could observe the places with color on the jade, analyze the distribution of color shades, and find the source of the color. If the color appeared out of thin air or only appeared at the crack, it was mostly dyed jade. The color of natural jadeite was not flirtatious, but clear and varied. ** 2. Other auxiliary identification methods ** 1. ** Look at the impurities ** - Since jade was formed in nature, if it was A grade, it would inevitably have some impurities, such as black, yellow or gray. However, the processed B grade had very few impurities because it was corroded by strong acid. 2. ** Touch and feel ** - Natural jadeite had a fast heat transfer and a cold feeling, while fake jadeite that had been processed with a large amount of chemicals had lost its original thermal conductivity. 3. ** Listen to the sound ** - During a slight collision, the sound of the A grade jade was crisp and continuous, while the fake jade (such as the B grade jade) would make a dull and intermittent sound. 4. ** Special Test Method ** - The hair could be wrapped around the jade and burned because the heat transfer of real jade was fast, while the heat transfer of fake jade was slower (such as glass). Therefore, if it really burned on the jade, the heat would spread quickly, the temperature would rise slowly, and the hair would not burn easily. The temperature of the fake jade rose very quickly, so it was easy to burn, but it should not burn for a long time. It could be judged as long as it was 1 second. - Prepare an electronic scale and a container filled with water. Place the container on the electronic scale, then reset the electronic scale to zero. Pull the bracelet up and let the bracelet float in the air (don't expose the top of the water surface and don't sink to the bottom of the water). This way, it can assist in the judgment. - Using a purple light, if it was a natural jade, it would not have a fluorescent feeling. If there was a very obvious fluorescent feeling, it must be a fake bracelet (mainly for fake jade that had been dyed and injected with glue). However, one had to be careful to choose a flashlight with three lights and turn on the purple light to illuminate it. 5. ** Weight Method ** - By weighing, it could also be used as a method of identification, but it required a comprehensive judgment based on relevant knowledge such as the density of the jade and practical experience. 6. ** Appraisal by a professional organization ** - If it was difficult to determine the authenticity of the jade, they could also seek professional appraisal.

To know the authenticity of jade, one could start from the following aspects: - ** Appearance observation **: True jade is a natural product. It is difficult for the texture to be completely uniform. There may be jade veins and jade flowers. Looking through the light, the surface had a warm luster. If there was color (such as green) inside, it was evenly distributed and there were no bubbles. Fake jade was dry, dark and lifeless. Some fake jade (such as glass fake jade) had small bubbles, and jade made of glass generally could not be processed into high embossed and round carvings. - ** Check Origin **: Take Hetian jade as an example. The authentic Hetian jade is produced in Hetian, Xinjiang. - ** Feel the weight and touch **: True jade feels warm and heavy. For example, Hetian jade from Xinjiang Real Estate had a strong sense of grease. Compared with ordinary stones, it had an obvious feeling of pressure and convenience. When it was first touched, it had a warm and cold feeling. Without rubbing it vigorously, it would not be heated by the hand immediately. Fake jade was rough and had no cold feeling. - ** Using optical identification **: You can use a magnifying glass or professional optical instrument to observe the internal structure of the jade. The texture of the real jade is natural and smooth. Fake jade may have unnatural features such as bubbles and flaws. - ** Distinguish skin color and pores (for Hetian jade seed material)**: observe the shape and size of pores, examine the direction and angle of scouring marks, explore the relationship between the smoothness of pores and jade quality, examine the degree of naturalness, and analyze the relationship between skin color and pores. Real Hetian jade seed material may have characteristics that are difficult to imitate, such as nail patterns, and the distribution is natural. - ** Pass hardness test **: When the jade is scratched on the glass, the glass will leave obvious scratches, but the jade itself will not leave any marks. - Listening to the sound: hang the jade with a thin thread and knock it with a hard object. The sound of the real jade is crisp and pleasant, and the aftertaste is melodious. The fake jade is dull and dry. - ** Check the color **: The color of real jade is natural, warm, and evenly distributed. For example, the color of natural jade has a gradual layering; the color of fake jade is often too bright and dull, and the color of artificially dyed jade is stiff and unnatural. However, even with these identification techniques, it was difficult to guarantee that there would be no mistakes in the face of the dazzling array of jade on the market. If necessary, they could seek professional institutions for identification. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
