Tian Huangshi is produced in the paddy fields and sands of the Shoushan River basin in Fuzhou. The original stones are mostly natural ovoid monoliths, which resemble Hetianzi jade, which is especially precious because of the excellent stone quality and difficult excavation. Tian Huangshi is delicate and moist, slightly transparent or translucent, and the radish pattern is obvious. The surface of the new field yellow has more stone skin and has a check pattern. These are important features of Tianhuang.
The total length of Shoushan River is about 8 kilometers. It is divided into geographical locations. The origin of Tianhuang is divided into Shangyu, Zhongli, Xiayu and Xiaxia. Shangyu is located at the source of the stream. The yellow is slightly lighter and clearer. The middle of the field is the most standard, the color is thick and tender; the lower jaw is in the lower stream, the stone is slightly lower than the upper and middle, and the color is dark.

There are many changes in the yellow color and texture of the field. According to traditional customs, it can be divided into four types: Tianhuang, Hongtian, Baitian and Hetian. According to the difference in hue, Rantian Yellow is divided into “Golden Yellowâ€, “Orange Orangeâ€, “Yellow Yellowâ€, “Osmanthus Yellowâ€, “Chicken Yellowâ€, “Rhu Lihuangâ€, “Saponin†and “Tung Oil Yellowâ€. "A lot of things." Among them, the special psychic fat, also known as Tian Huang frozen. The color of Hongtian is bright and colorful, like red orange peel. This kind of stone is very rare. Baitian is white and yellow, not pure white; blackfield has pure black, gray and black, etc., pure black field, its black body is slightly black; gray black field is not pure black, slightly light gray. Another "silver bag gold" (white appearance, yellow inside) and "golden package silver" (as opposed to the former), which is called "golden and silver land" by local people, is very rare.
Because Tian Huangshi is rare and rare, its counterfeit goods and shoddy yellow are often seen on the market. However, as long as the stone of other Huangshou Mountain mixed with Tian Huang is clarified, it is not difficult to distinguish them. Although the excavation Duling pit, the excavation mountain and the excavation pit are all alluvial sand ore monoliths like Tianhuang, but the secondary living environment is different from that of Tianhuang, the degree of acidification of the stone surface is not as deep as Tianhuang. Although these stones also have radish patterns, they are not warm and greasy, and the excavation dulings are clean and firm. The excavated alpines are fine and loose. Although the excavation pits are similar to Tianhuang, there are white spots such as eggs. Also different from Tian Huang. The deer mesh is also a monolithic monolith, fine and moist, but opaque and without radish. The underarms are hard and sturdy, without stone skin, without radish lines, and many white bubbles in the stone. This feature is easy to distinguish. The Shanbo Cave is the totem of Duling. It is slightly firm and translucent. The muscles contain fine metal dots and powdery white blocks like “peanut cakesâ€, so it is not difficult to distinguish. Lianjiang yellow matter is hard and multi-cracked, its grain is thick and straight, and it is obviously different from Tianhuang. The color of Litchi Cave is psychedelic and radiant, but it is not enough.
The old and new fields of Huangshi have new pits and old pits. Generally speaking, the old land was unearthed before the Republic of China, and the modern production was called the new pit yellow. People think that the old pit is better than the new pit. That is because the texture of the old pit is fine, warm, greasy, and the radish pattern (also known as the orange sac) is clearly distinguishable and slender and dense. The feeling of entering the knife is particularly pleasant, and can be summarized by a word "糯". The chapters are mostly square and rectangular carved buttons, and there are also no carvings, and a natural six-sided square. In addition, due to the age of the old pitfield yellow, there is a layer of cute "shell" (commonly known as patina), which looks ancient. The new pitfield yellow also has radish patterns, but the texture is excellent and inferior, the temperature and fineness is inferior to the old pit, and the shape is especially natural. Another important feature of the new pitfield yellow is that the outer surface is often covered with a layer of yellow or black cortex, and the body has a red rib-like plaid. Through the stone skin, the gradually weakening muscle can be observed. people. Today, there is a saying that "nothing is not a field". In fact, "ge" is the meaning of the crack in the Fuzhou dialect. The crack is a sputum after all, it is a kind of stone disease, and the "grid" is not a good stone. If you look at the "grid" Cheng is the symbol of Tian Huang, and it is a big mistake to judge the authenticity of Tian Huang with or without the "grid" pattern.
