Both stiff and cotton belong to Hetian jade. Both seem to have a certain similarity. They are all white dots and are easily confused. Panyu is also a study. Many people pay more attention to the problem of stiffness and cotton. Is it a problem in the process of playing for a long time? First you have to know what is stiff and cotton? Hetian jade's stiffness: In the formation process of Hetian jade, the whiteness and grease luster of jade have increased due to the absorption of calcium and magnesium in the permafrost surrounding rock. However, if the content of absorbed calcium is too much, it will be precipitated by the microcrystals during the formation process to form a white loose point. These white dots are the rigid words of the saying. Hetian jade's cotton: Cotton is an aggregate of white crystals in Hetian jade. It is mostly needle-shaped or flower-like, and its composition is silica. Most of the cotton can be seen only by the naked eye, but there is also a little bit of cotton in the jade, which is hard to find in the natural light. But a light can be found. Generally speaking, if the cotton spot is difficult to find with the naked eye, then its influence on the aesthetics of the jade piece is relatively small. Unless it is perfect for perfection, the cotton spot that is generally invisible to the naked eye can be ignored. Although the two of them look similar, they are all white dots, but there are essential differences. Cotton is generally easy to appear in relatively transparent materials, like mountain materials, especially Qinghai. Why is cotton easy to appear in a more transparent material? Because the more transparent material is rich in silica, the white jade cotton is also composed of silica. However, silica is very stable, so cotton cannot be smashed during the playing process. White jade with a higher calcium content will appear white, and it will easily appear in these materials, and its penetration is extremely strong. Now I know why the stiffness is easy to follow! The extremely thin stiff surface on the surface is likely to be discarded. The calcium oxide in the grain gap is slowly taken away by the uric acid in the sweat. But sweat is difficult to get into the jade, so you can only discard the thin stiff flowers near the surface. The ancients "the beauty of jade is innocent", possessing an innocent jade is undoubtedly the desire of everyone who loves jade. But no one is perfect, and jade is the same. Even the collectors who have been playing jade for many years are also coexisting with Yu Yu, and there are some "faulty" jade materials. Therefore, it is necessary to correctly understand the cotton and stiffness of Hetian jade. SHAOXING YINGSIPE TEXTILE CO.,LTD , https://www.chinayingsipei.com
