Natural jade jade contains more or less different clefts, and these cracks are also fatal weaknesses in jade, but it depends on the situation. If the crack is small, not obvious enough, the overall impact on jade Smaller, the crack is usually negligible, but if the crack contained in the jade is too large and deep, it can basically be judged as waste. The so-called splitting is a general term for all cracks contained in jade, and depending on the size of the crack, a small crack is called a sputum; a large crack is called a crack. Usually the formation of these splits may be caused by geological effects in the process of jade formation; it may also be caused by improper mining and processing. According to the shape and distribution of the splitting, the whole can be subdivided into two categories, one is the splitting and the other is the active splitting: Dead cleft palate refers to the obvious cleft palate, the thickness of the crack is different, the length and the length of the crack are different, the long and deep meets the cockroach, the two sides are shallow and the middle is deep, the jade inside the jade, etc.; The split refers to the relatively small splitting. It is mainly distributed on the surface of the jade, such as the crevice-like gap. From the outside to the inside, there is a scaly-like fire damage, and most of them are small cracks with the same direction. Generally speaking, the cleft palate inside the jade material is difficult to predict, and the dead cockroaches are easy to remove, and the live cockroaches are often difficult to remove. 100% Cotton Woven Fabric,Multi Size Cotton Poplin,100% Cotton Poplin,100% Cotton Fabric For Dress SHAOXING CITY CHENYAO TEXTILE CO,LTD , https://www.chenyaotextile.com
