Water color is the three natural properties of jadeite, to understand jadeite, you must recognize its three major attributes. Species rely on microscopy, color can be intuitive, water depends on the sense, and the sense is often the most charming. Water is good and bad, how to distinguish whether it is good or bad? And the water can be adjusted, do you know how to adjust?
Water is the head of the water, according to the length of the distance that light can pass through inside the emerald, the industry calls it "a few points of water", generally one to three points, three points of water is the most transparent. One part of the water means that the light transmission depth is about 3 mm. The transparency depth of bipartite and tertiary water is about 6 mm and 9 mm.
In other words, it is easier to understand that jadeite with a thickness of 3 mm is fully transparent, and in the same way, bi-water and three-point water refer to jadeite with a thickness of 3 mm and 9 mm respectively are fully transparent. Emeralds with a thickness of less than 1 mm are poorly transparent or opaque, which is commonly known as water difference and dry water, and the length of the water head is generally estimated by the naked eye. The state of transparency reflects, to some extent, the length of emerald water, that is, jadeite water can be metered with transparency.
Water is inextricably linked to transparency.
Transparency refers to the degree of light transmission of jadeite, and the national standard for jadeite grading divides the transparency of jadeite into five levels: transparent, sub-transparent, translucent, micro-transparent, and opaque. Transparent: Most of the light is permeable, and the internal features of the emerald are clearly visible. Sub-transparent: Most light is permeable, and the internal features of the emerald are visible. Translucent: Some light is transparent, and the internal features of the jadeite are still visible.
Emerald water is a comprehensive state formed after the light propagates inside the jadeite and is reflected and refracted by the multiple disorderly cross-reflections and refractions of the grains, like a fog haunting, deep, no sense of layering, and is a combination of transparency and seed and substrate.
The water that can only be produced when the jadeite species is old, the grain is small, the structure is tight, and the substrate is pure is an optical phenomenon that is more transparent than the transparency. Water is the effect of the synthesis of various factors, is the result of the action of light inside the emerald, transparency is the basic element of water, the lack of species, the bottom of the cooperation, simple transparency will not be converted into water. Where there is water, it must be transparent, and transparency does not necessarily mean water. Emerald water is a state, transparent or translucent condensed like a dark wave in the lake, as if still and like a surge. Green contains water, then green is faint, elastic, and seems to be boundless. If there is no color and water, it is as clear as a stream.
Transparency ≠ water
Transparency is a physical definition, expressing physical properties, such properties exist in large quantities in other mineral crystals, such as crystal, glass, etc., but these mineral crystals are only transparent, there is no water, there is water is a unique property of jadeite. For jadeite, transparency is the basic condition for jadeite to have water, there is transparency may not have water, many transparent or translucent jadeite have no water, disguised affirmation of the fact that the essence of jadeite water is not transparency, the understanding of transparency as water is an illusion, the two can not be equated. The biggest difference between jadeite and other jade types or mineral crystals is that transparency is more common, while water is only unique to jadeite!
Although transparency is not the only factor that determines water, if it is not transparent, there will never be water, transparency or not has a huge impact on water, and the level of transparency can affect the shape of water. The more transparent it means that more light enters the depth of the jadeite, and the light alternates with the combination of seed and substrate, and it is easier to form water. Thus, the trick to purposefully let more light into the jadeite is the water transfer of the jadeite. 【Water transfer】Adjustment: adjustment, adjustment. Water: Head. Water transfer is the regulation of the water head.
Water is the natural property of jadeite, and the reflection of the head of the water is closely related to light, natural properties we can not change, but we can change the light. So knowing the principle of the head, we can transfer water.
Polishing, forcing the surface of jadeite to be smooth and delicate, as shiny as a mirror, translucent, can well concentrate external light, favorable light penetrates the surface into the interior, and then forms water. If the surface of jadeite is rough, the species is poor, and the transparency is weak, and the water is weak or waterless. Therefore, by adjusting the light and transparency, the purpose of water transfer can be achieved.
The use of sculpting techniques is the main method of water transfer. For example, when carving, the back of the uncarved is processed into a concave yin side (arc surface), expanding the light receiving area, absorbing more light, sacrificing thickness, improving light transmittance and transparency, so that the jadeite is easy to get out of the water, the back of the head of Guanyin, the belly of the Buddha and the back of the head are often dug thin, that is, this method is used to adjust the water.
For the case where the green is darker and the thickness of the color block affects the transparency, the carving process outlines the demarcation between green and colorless, appropriately reduces the green thickness of non-important parts, makes the light transmittance better, the transparency is clear, and achieves the effect of water, reflecting the green ice fresh and tender, color grading.
There are also restrictions on thinness, too thin jadeite, there is a visual effect of light transmission and high transparency, but often there is still no water, which is due to the fact that the light needs a certain depth to interact with the species and the bottom to produce water.
Inlaid back cover is another type of water transfer method. The bottom refers to the back, and the inlaid back cover is that when inlaying, the back of the jadeite is wrapped in a whole piece of metal. Using the curvature and metallic gloss of the back cover material, additional light is collected and reflected on the jadeite, strengthening the surface gloss, which in turn affects the adjustment of the color, playing the same effect as water. It must be pointed out that with the cancellation of the back cover or the opening of the active back cover, the light and shadow created by the back cover also disappear, which is essentially different from the carving of water transfer.
Emerald water, mysterious and amazing, after unveiling the hazy veil, found that the emerald aura that was painstakingly sought was water. Water, but also a distinctive and unique feature of jadeite can distinguish it from other jade, no one can stand out, her lust, her beauty, people can not resist, can not forget. That's the beauty of jadeite.
Well, today's jadeite knowledge is introduced here, continue to pay attention to Oh ~
