Jade identification was the process of studying the age, authenticity, and artistic level of the jade. The following are some common jade identification methods: 1. ** Color distinction **: The color of natural jade is natural and evenly distributed. However, it was necessary to be wary of some illegal merchants who would use dyeing and other means to pass off the inferior ones as good ones. They could use the spectrum to detect the spectral characteristics of the color, and at the same time, observe the degree of color distribution under natural light. The color of natural jade was too natural, and the color of dyed jade might be piled up or too uniform. 2. [Touch: Due to the different density of the jade, the touch will be different.] For example, Hetian jade was denser and heavier than ordinary jade. 3. ** Light observation **: For example, when the light shines on the Hetian jade, you can see the evenly distributed fiber interwoven texture. 4. [Distinguish by sound: The sound of natural jade is crisp, but the sound of artificial processing is muffled.] For example, the sound of the real jade was clear and loud, while the fake jade sounded low. 5. [Water Droplet Identification Method: When a drop of water is dropped on a piece of jade, it will turn into a dewdrop and not disperse for a long time. It may be a real piece of jade. If the drop of water disappears quickly, it may be a fake.] 6. [Tongue Licking Method: When the tip of the tongue licks real jade, it will feel astringent, but fake jade will not feel astringent.] 7. ** Magnifying Glass Observation **: Use a magnifying glass to see if there are any cracks. Those without cracks are high-quality jade, and those with cracks are second-class. The more cracks there are, the lower the value. In addition, from the perspective of historical aesthetics, it could also assist in the judgment. If an ancient jade was very much in line with contemporary aesthetics, then it might be necessary to pay more attention to its authenticity. During the identification, professional instruments could also be used, such as a high-power magnifying glass to see the fine structure of the jade, and a refraction instrument to measure the refraction index of the jade to provide reliable data support for the identification. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some free jade bracelet identification methods: 1. ** Color observation **: The color of a natural jade bracelet is evenly distributed and the transition is natural, but the color of a fake jade bracelet is unnatural. When you look at it with a magnifying glass, you may see traces of dye residue. 2. ** Check the luster **: Natural jade has a strong luster and is clear and translucent; B grade jade has a weak luster and looks foggy. The color of the bracelet treated with polishing powder is floating on the surface. The fine particles can be seen with a magnifying glass. The color is turbid and unnatural. When the light is turned on, the fog can be seen. It may fade if it is wiped with a white cloth stained with alcohol. 3. ** Look at the internal structure **: The internal structure of the A-grade jade is tight. The well-planted jade will have a sticky feeling and hardness through reflection. The B-grade jade can be seen under the reflection of light, and the internal structure is loose. 4. ** Check the cleanliness **: The jade of Grade A contains a small amount of impurities, such as black spots, other dirty colors, and rust color. The jade of Grade B is clean inside and generally does not have rust color. It will be purple fluorescent when it is illuminated. 5. ** Look at the jadeite nature **: The jadeite nature is a unique feature of jadeite. It refers to the reflection of the jadeite mineral cleavage surface that can be seen directly on the surface of the jadeite. It is commonly known as the "fly's wing". Other imitation jadeite materials do not have the jadeite nature. 6. ** Listen to the sound **: Gently knock on the jade bracelet. The sound of the natural jade is crisp and pleasant. The fake jade bracelet has been damaged due to the acid washing process. The sound is dull. 7. ** Observe the surface **: Use a magnifying glass to observe the surface of the jade bracelet. Fake jade bracelets can see the net-like acid wash patterns, but natural jade bracelets don't. 8. ** Hardness check **: Real jadeite is very hard and not easy to be scratched or worn. The texture is relatively hard. Fake jadeite is relatively soft. However, these methods could not guarantee 100% accuracy. If you were not sure, it was best to choose a regular jewelry store or appraisal agency for identification. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!

Currently, there were some channels that could provide free jade appraisal services. For example, the Nanjing Quality Inspection Institute once launched a quality monthly public welfare inspection activity. During this period, the National Gold and Silver Quality Supervision and Inspection Center provided jewelry and jade identification services to the public for free, but this was an activity for a specific period. In addition, some organizations claimed to provide professional free appraisal of jadeite, but the specific details and authenticity needed further verification. At the same time, although some of the e-commerce platform's appraisal shops had paid appraisal services, they also mentioned that they could provide online appraisal services (for example, jade could be appraised online by providing photos and videos for 10 yuan per piece). There was no general and long-term service that was completely free and specifically for online appraisal of jade. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!

The method to identify the sound of jade was as follows: the usual method was to bind the jade bracelet with a thin thread and hang it in the air. Then, use a rubber rod or glass rod to gently knock the jade bracelet and observe the sound it made. The sound of natural jade was crisp, similar to the sound of metal colliding, while the sound of glued and colored jade was dull and turbid. However, it was important to note that there were many restrictions to identifying jade by listening to the sound. This method was only effective for B grade jade, 83 jade, and some other stones that were disguised as jade. If it was polished and dyed, the sound would be the same. For C-grade jadeite (only artificially dyed, without acid washing to destroy the structure of the jadeite), the sound of knocking was as clear and pleasant as natural jadeite. Moreover, with the development of counterfeit technology, the strength of the organic glue used to fill the "high-grade" jade was very high. The fake jade also had a strong luster, and the knocking sound was very clear. It was almost the same as the A-grade jade, so it was difficult to identify it by sound. Therefore, judging the authenticity of the jade by listening to the sound was only a reference at best. It must be combined with other identification methods to accurately determine the authenticity of the jade, such as looking at the surface characteristics of the jade, comparing the identification certificate, etc. It even had to be taken to a professional appraisal center. Only by using professional instruments to detect the density, refraction index, and Polarized Light of the jade could the authenticity and grade of the jade be determined.

Jade ornaments of different historical periods had their own characteristics, which could be used to identify them: ** 1. Neoliths ** - Most of the jades were plain and had no patterns. Even if there were, they were very simple, with inky lines, dragon patterns, fish patterns, and animal patterns. The style was simple and unadorned. ** 2. Xia, Shang and Zhou dynasties ** 1. ** Xia Dynasty ** - The carving was simple, it was a Yin line carving. 2. ** Shang Dynasty ** - The patterns were mainly cloud patterns, string patterns, dragon and phoenix patterns, among which cloud patterns were the most basic. The carving technique developed into double Yin lines, forming a Yang line between the two Yin lines. There were also unique ridge tooth patterns and dish patterns. The ridge tooth patterns were no longer used in later generations, and the dish patterns were unique to the Shang Dynasty. 3. ** Zhou Dynasty ** - One side of the decorative carving was a Yin line, and the other side was a slope line. The Yang character formed between the two had a slanted feeling, and there was a change of light and shadow. ** 3. The Spring and Autumn Period and the Warring States Period ** - Cloud patterns, valley patterns, nail patterns, and taotie patterns were more common. The dragon and phoenix patterns were very unique. Most of them were back-to-back in an "S" shape. The patterns on the jade wall were carved densely, using techniques such as carving, embossed, and line carving. The inner and outer circles protruded the outline, and the lines were twisted and psychedelic. The grain pattern was a row of dense small dices in the shape of a vortex. The dices pattern was commonly seen on jade. The pattern was in the shape of a raised papillary-shaped round dices, which were either vertically and horizontally or arranged with the body. The circle pattern was popular. It was a small circle arranged in rows. There were single circles, concentric circles, and small dots in the circle. ** IV. Han Dynasty ** - In addition to the geometric patterns (such as vortex pattern, valley pattern, cattail pattern, hole nail pattern, etc.), the elephant pattern dragon pattern, animal pattern, bird pattern, etc. were more complicated. There were also some simple and freehand decorations, such as Han Yu Chan and Yu Weng Zhong Ren, which reflected the style of "Han Eight Blades". ** V. Tang Dynasty ** - Plant patterns increased, such as lotus petal patterns, sunflower patterns, peony patterns, lily patterns, etc. The realism of the decorative patterns was mostly expressed by a large number of fine Yin lines. When depicting bird feathers, the fine semi-circular scale patterns or square patterns were used to express its lightness and delicacy. The lines were soft and smooth, soft and firm. ** 6. Song and Yuan Dynasties ** - The patterns were rich and colorful, mostly dragon and phoenix auspicious patterns. In addition, there were ancient dragon patterns, inscriptions, breast patterns, phoenix, peony and other patterns. ** 7. Ming and Qing Dynasties ** 1. ** Ming Dynasty ** - There were mainly patterns of pine, bamboo, plum, cloud, cloud, dragon, flowers, mountains, rivers, people, and so on. Engraving also began to appear on the jade. 2. ** Qing Dynasty ** - In addition to the ancient decorative patterns, new decorative patterns such as flowers, birds, and wormgrass were added. Imperial poems and various inscriptions also appeared on the jade articles. In addition, understanding the time of the "birth" of the decorative patterns could help determine the "birth" of the jade ware. If the decorative patterns of the previous dynasty appeared on the shape of the previous dynasty, it was likely to be a pseudo-ancient ware. For example, the web-like pattern in the Hongshan culture appeared in the form of auxiliary patterns in later generations; the unique animal face pattern of Liangzhu jade articles did not appear in later generations; the silk pattern was used for a long time and was still used on bracelets until the Qing Dynasty; the string pattern appeared in the Hongshan culture, but it was more common in hoop-shaped and wall-shaped articles in the Shang Dynasty, but rarely seen in later generations; the cloud pattern first appeared in the Shang Dynasty and was popular in the Spring and Autumn Period, the Warring States Period, and the Western Han Dynasty. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
