What is the "water head"? In fact, it is a kind of evaluation standard for the degree of transparency of glass jade. In the jade industry, the use of transmitted light for every 3mm of jadeite is called “one waterâ€. The better the water head, the better the degree of transparency. Correspondingly, the impurity content of jadeite is less and the texture is finer. The smaller the mineral crystal particles. Another factor that affects the jadeite product is the fineness of the jadeite. The finer the texture of the jadeite, the visual effect after polishing the “water†is definitely better than the coarse jadeite. "Water" is an important factor in the evaluation of jadeite. It is commonly known as "water head" in the industry. The high transparency is the water head. This kind of jade is crystal clear and translucent, giving people a feeling of water, and the poor transparency of the jade is dry and dull. With a dry feeling, it is the head difference and the water is insufficient. The transparency of jade can be roughly divided into transparent, transparent, translucent, micro-transparent and opaque. The more transparent the jade, the higher its value: Level Transparency Sunshine progress Common commercial varieties Level 1 Transparent 10mm or more Pure colorless old glass Level 2 is more transparent 6~10mm A small amount of old glass grade special grade Level 3 Translucent 3~6mm Old-fashioned glass and ice specialties Grade 4 Micro-transparent 1~3mm Concentrate, coarse grain, new and old species Level 5 opaque sunlight does not enter color, bottom, new species JINAN DASHUN TEXTILE &GARMENTS CO.LTD. , https://www.dashuntex.com
