When it comes to jadeite water, everyone may think of transparency first. Therefore, many people simply think that jadeite water is the transparency of jadeite. In fact, this is an inaccurate concept. Emerald water seems simple, but it is actually a relatively complicated concept. So what is the essence of it?
Water is the head of water. According to the length of the 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 the most transparent. The water penetration depth is about 3 mm. Divided water and three-part water have a transmittance depth of about 6 mm and a diameter of 9 mm. Or, to put it another way, it is easier to understand that a jade with a thickness of 3 mm is completely transparent. Similarly, dichotomous and three-divided water refer to jade with a 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 is closely related to transparency. Transparency refers to the degree of light transmission of jadeite. The national standard of 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.
The water of jadeite is a kind of integrated state in which light is transmitted inside the jade, and is formed by multiple disordered cross-reflection and refraction of crystal grains. It seems to be hazy, deep, and layerless. It is a combination of transparency and species and foundation. . The water that can be produced when the emerald is old, the grain is small, the structure is tight, and the foundation is pure, is an optical phenomenon more than transparency. Water is the result of the synthesis of various factors. It is the result of the action of light in the interior of jade. Transparency is the basic element of water. Without the cooperation of species and foundation, pure transparency will not be converted into water. If there is water, it will be transparent, and the transparency will not necessarily have water. Emerald water is a state in which the transparent or translucent stagnation is like a dark wave in a lake, and it seems to be static and surging. Green watery, green and sturdy, elastic, like a marginless. Colorless and watery, it is as clear as a stream.
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 biggest difference between jade and other jade species or mineral crystals is that transparency is more common, while water is only unique to jade.
Although transparency is not the only factor determining water, opacity will never have water. Whether transparency or not has a great impact on water, the level of transparency can affect the shape of water. The more transparent, the deeper the depth of light entering the jade, the light interacts with the seed and the base, and it is easier to form water. Thus, the trick to purposefully let more light enter the jade is the water of the emerald.
Grinding and polishing, forcing the surface of the jade to be smooth and delicate, such as mirror-like luster, translucent, can well converge external light, and it is beneficial for light to penetrate the surface and enter the interior, after which water can be formed. If the surface of the jade is rough, the species is poor, and the transparency is weak, the water is weak or waterless. Therefore, the purpose of water transfer can be achieved by adjusting the light and transparency. Tune: adjustment, adjustment. Water: head. Adjust the water head by adjusting the water.
The use of engraving techniques is the main method of water transfer. For example, when engraving, the back surface is processed into a concave white surface (curved surface), the light receiving area is enlarged, more light is absorbed, the thickness is sacrificed, the light transmittance and transparency are improved, so that the jade is easy to effluent, Guanyin The back of the head, the belly of the Buddha, and the back of the head are often dug. This method is used to transfer water.
For the case where the green color is darker and the color block is thicker and the transparency is affected, the green and colorless boundary is stripped in the engraving process, and the green thickness of the non-important part is appropriately reduced, so that the light transmittance is better, the transparency is clear, and the water effect is achieved. The green ice is fresh and fresh. There is also a limit to thinness. The jadeite is too thin, and has a light-transparent, high-viscosity visual effect, but it is still still waterless. This is because the light needs a certain depth to interact with the seed and the base to produce water.
Inlay backing is another type of water transfer method. The back of the bottom finger is inlaid on the back of the jade, and the back of the jade is covered with a whole piece of metal. Using the curvature of the backing material and the metallic smooth surface, the extra light is reflected and reflected on the jade, which enhances the surface gloss, which in turn affects the adjustment of the chromaticity and has the same effect as water. It must be pointed out that with the cancellation of the back cover or the opening of the event back cover, the light and shadow created by the back cover disappears, which is essentially different from the engraving and water transfer.
