There are some flaws in the natural jade agate, and this problem is naturally unavoidable in the South Red Agate. Common jade mites are mainly cracks, lines, water lines, cotton, etc. Different ç‘•ç–µ have different effects on Nanhong. Outer crack The formation of Nanhong is inseparable from iron. Baoshan in Yunnan and Liangshan in Sichuan are the main producing areas of Nanhong because they are rich in iron ore. With the popularity of Nanhong, its "fracture" characteristics are gradually becoming known. In fact, this is no stranger to South Red, it is also no way, Nanhong is the ore formed after the volcanic eruption, often subjected to high temperature and high pressure, plus various crustal movements, temperature changes and other environments, it is difficult to crack. Outer cracks, generally throughout the entire block of South Red (at least the majority), are white lines, you can touch the hand, you can also feel the obvious bump. Although it is said that “no cracks are not southâ€, serious cracks will greatly affect the price of finished products. However, there is a cloud in the old saying: beautiful jade is not awkward. If it is a slight outer crack, you don't have to care. After all, this is also a natural proof of Nanhong. And some small cracks can increase the beauty of its precipitation. In addition, some highly skilled masters will cover up the existence of external cracks by engraving. Internal crack The cause of the internal fissure is the same as that of the outer fissure, but the internal fissure is not as obvious as the outer fissure. It is mostly subtle and untouchable (hidden inside), and some can be seen in natural light, but most need to be glare to see . In fact, the internal crack is extremely common in South Red, and its impact on the value of the finished product is not large, unless it is particularly obvious. Impurity Nanhong's "heterogeneous" is as common as its "crack". The cause of miscellaneous is very simple. Nanhong is formed by volcanic eruptions. During its formation, it is mixed with black volcanic rocks (or associated minerals, sundries, groundwater, etc.). ).....It became "hetero". If the area of ​​the miscellaneous is large and obvious, it will make Nanhong’s price plummet. "Miscellaneous" includes black, black lines, black spots, ore points, etc. These things only affect the aesthetics of Nanhong, and do not affect its physical properties. There are also a lot of Nanhong's shackles in the hands of the sculptors. Instead, they have the effect of adding icing on the cake, making Nanhong look more beautiful. So we can't call it ç‘•ç–µ, but the magical highlights. Water line The waterline is formed due to changes in the geological environment. There is a squeeze and re-fusion between the jade, the density of the material is different, and then the waterline is produced. In fact, Nan Hong will have some water lines more or less, even if the texture is even better. The waterline is a bit like a crack, and many people can't tell. At this time, it is necessary to use tools. Under the illumination of strong light flashlight, the water line can transmit light and crack. Whether the waterline is a bright spot or a slap, it is mainly based on personal preferences. Nanhong, which has a waterline, is generally fine in texture and looks fresh and beautiful, so it is loved by many people. For example, a lot of ice-floating materials, even if you can directly see the waterline without lighting, but almost no one thinks it is awkward. Cinnabar point Cinnabar point, in fact, this is a unique feature of Nanhong. It is to observe Nanhong through a strong light flashlight. You can see a grainy closely arranged substance. It is the "cinnabar point" in Nanhong (the main component is red). iron ore). The combination of many fine cinnabar points forms the "red" that we finally see. The more densely distributed, the more the number, the more reddish the color. If you want to enjoy the cinnabar point or go to see the ice floating south red, many engravers will use the distribution of cinnabar to create some beautiful pictures. So now, the obvious red cinnabar point has begun to be loved by everyone, and the price should gradually increase. suzhou bangneng textile co.,ltd , https://www.bangnengtowel.com
