"Old cooked" and Tianyu, the material is more delicate, oily and mellow, the material is pure, the biggest feature is that the material is "cooked." Whether or not he is familiar with Tian Yu in the eyes of experts is an important criterion for judging the quality of Hetian jade. How to judge the "old-fashioned" Hetian jade? Hetian jade's "old maturity" is mainly from jade, luster, structure, feel, skin color and so on. "Old cooked" seed jade, some people say that its white is slightly yellow, some people say that its white will be slightly powder, in fact, they all want to describe "fat white." The color of "cooked" jade should be a warm white tone with oily luster. This color will naturally give people a sense of intrinsic light, not very white, but it is more quiet than white, it seems jade And people can be integrated into it. The five characteristics of "old cooked" and Tian Yu: 1, 浑 thickness: When Hetian jade is selected, purity, fineness, thickness and density are well-known indicators. An old cooked material must have good fineness, density and mixed thickness, and a piece of raw material, which may have fineness and density, but under-mixed thickness. 2, gloss: In general, the skin of cooked jade is oily and shiny, with a warm white tone, which looks like a very close and gentle feeling. 3. Structure: Under the condition of various natural and artificial light sources, the naked eye has no structure, which means that the jade is very dense. The density and hardness of the "cooked" jade will be slightly higher than that of the ordinary jade. Sometimes it will be obvious, but it is different from the "sweet" of Qinghai water, which is the "mating" of both toughness and rigidity. The overall observation of the "cooked" jade's texture is flexible and reveals rigidity, which will give off a sense of treasure. 4, skin color: Most of the skin color of "cooked" jade is sprinkled with gold, and most of it is live skin and oil skin. In the old saying, there is a certain reason for "sipping the golden fat from the golden skin." In some "old-fashioned" white-white seeds, we often feel that there is a layer of light yellow wrap on the surface of the skin. In fact, this is also a layer of sprinkled gold, so the meat inside the material will often It is more white than the surface. 5, feel on: The "cooked" jade is held in the hands of the feeling of rubbing, such as the baby's skin-like feeling of fat will appear at this moment, smooth and smooth, no delay, and even worry that it will come out. The concept of relatively familiar is that tender, raw, such as Qinghai. Shandong EMF New Material Technology Co., Ltd , https://www.earthingsilver.com
