"The layman looks at the color, the insider sees the species" I believe you must have heard it. Many people like colored jade, but for example, if it is a full-color bracelet, but there is no water at all, it seems that it is missing. A smart feeling.
The species of jade refers to the general term for the green and transparency of jade, and there is also a saying that the structure and transparency of jadeite. It is an important symbol for judging the quality of jade. Its importance is no less than the color, the intrinsic amateur color, and the kind of jade that can be used to make the jade of light color look warm and crystal, and even green. Full of jade, clear and full of aura.
What is water?
Water is the head of water. According to the length of light that can pass through the interior of the jade, the industry calls it “a few points of waterâ€, usually one to three minutes, and the three-point water is more transparent. The water transmission depth is about 3 mm, and the water separation depth of the two water and three water is about 6 mm and 9 mm.
Another common way to understand this is: a water-dividing finger with a thickness of 3 mm is completely transparent. Similarly, two-water and three-point water refer to the thickness of 3 mm and 9 mm, respectively, which is completely transparent. The emerald with a thickness of less than 1 mm is poorly translucent or opaque. It is commonly known as water difference and water dryness. The length of the water head is generally estimated by the naked eye. The state of transparency reflects to some extent the length of the jade water, that is, the water of the jade can be measured by transparency.
Water and transparency: Transparency refers to the degree of light transmission of jadeite. The national standard for jadeite classification divides the transparency of jadeite into five levels: transparent, translucent, translucent, micro-transparent and opaque. Transparent: Most of the light is permeable, and the interior features of the jade are clearly visible. Sub-transparent: Most light is permeable, and the interior features of the jade are visible. Translucent: Some of the light is permeable, and the interior features of the jade are still visible.
Transparency is not equal to water
Transparency is a physical definition that expresses physical properties. Such properties exist in many other mineral crystals, such as crystals, glass, etc., but these mineral crystals are only transparent, without water, and water is unique to jade. nature.
For jadeite, transparency is the basic condition for jadeite with water. There is no need for water for transparency. Many transparent or translucent jadeites have no water. In disguise, the essence of jadeite water is not the fact of transparency. Transparency is regarded as water. Understanding is an illusion, and the two cannot be equal. The difference between jade and other jade species or mineral crystals is that transparency is more common, while water is only unique to jade!
The goodness and poorness of jadeite water also determine the quality and difference of jadeite quality, and their prices may differ by a thousand times or more. If the water is not good, even if it is full of green jade, its color will be dull and monotonous.
No-alkali accelerator are used to increase the rate of concrete strength development or to reduce concrete setting time. It is non-toxic, non-corrosive, non-flammable, chlorine-free, harmless to human health, low in springback, no dust and no pollution during construction, which can greatly improve the construction environment .
