The identification of sugar jade and seed jade

Sometimes it is very difficult to distinguish between two types of jade. It has no distinction between true and false. It is only good or bad. If two people have different opinions, the result of not knowing the goods is not getting good goods. Since ancient times, those who play jade jade, are all in love with Hetian jade seed material. This is not only because it has a more delicate and moist jade than the mountain, but also because of its unique colorful skin that has been dyed in years.

What is Tsai in the end? Aberdeen, also known as Aberdeen, refers to the Hetian jade seed produced in rivers or on riverbeds. It is the snow melting water carried and washed from the hill. Because of long-distance transportation and abrasion, it forms many small pieces of material that are sleek and shaped like goose eggs. The big ones are like fists and the others are like millets. Tsai's delicate texture is less cracked, shiny and oily, highly transparent, often with skin. Sugary jade and Tsai jade have similar appearances and are often considered to be the same jade material. In fact, there is a difference between the two. The reason why Tsaiyu and Yucai are favored by people is because their skin color is festive and they can enhance the movement of jade. Second, the quality of jade is very good. For Tsai Yu and Yuchao Yu, the "Qiao" of color is "Heaven and Earth", while the "Qiao" of work is "Aura of People". Doesn't the combination of the two make a wonderful masterpiece? Jade color jade production, in the long history of Chinese jade is a rich cultural heritage chapter, the use of a variety of colored jade craftsmanship made of jade, do not be rich and interesting.

There is a layer of brownish-red or brown-yellow skin on the surface of the jadeite. The thickness of the skin is very thin, generally less than 1 mm, and its various forms, such as clouds, veins, scattered spots. The formation of color skin is due to the fact that ferrous oxide in Hetian Yuzhong is converted to iron trioxide under oxidative conditions, so it is secondary. Jade skin varies in shades of color. The jade circle is named after various colors. There are light white, tiger skin, orange peel, autumn skin, black skin, and deer skin. From the skin color, the quality of the jade can be seen. The same kind of quality jade, such as the skin color with autumn pear, is more valuable. It can be seen that Hetian Yuzhong's sugar jade and Tsai jade are not side-by-side varieties, and their classification basis is different.
