Detail the classification of Hetian jade raw materials
Hetian jade raw materials are generally divided into three types: mountain material, mountain stream water and sub-jam. The mountain material is collected from the original jade mine on the mountain; the mountain water and the sub-material are the weathered caving of the original jade mine, and then washed and transported by rainwater and river. In the river, the aquatic jade mine formed by the river's long-term rolling, weathering and abrasion is usually taken from rivers or dry riverbeds. First, the seed material Ziyu is also known as Zizi and Zizi. Hetian jade seed material is a secondary mine, which comes from mountain materials. The jade quality is better than the mountain material and has high value. It has become the first choice for people. The texture of the seed material is fine, the oil is smooth and clean, and its shape is not big. It is like pebbles. It is round and full. The surface of the seed material often has a skin color. This is because the river water will change the color of the jade, the skin color of the seed material is beautiful, and it can be made. Into a beautiful and pretty jade. "Ten seeds and nine cracks", the seed material is often collided by the river water, and there are more splitting, which is its distinctive feature. Because of the action of the river water, the corners of Hetian jade raw materials are smoothed and the oil is very strong. Second, mountain material The mountain material is the Hetian jade original ore. It is characterized by large and small blocks. The jade shape is irregular and the edges and corners are distinct. The surface of the jade material is rough and the structure is relatively loose. The quality is often inferior to the seed material. Despite this, the mountain material has become the main material used in Hetian jade with its huge output, and there are also jade stones of excellent quality in the mountain material. Third, mountain water It is also the Hetianyu secondary mine. Like the seed material, the jade material is formed by the mountain material being brought into the river. However, the mountain water is not fully affected by the river water. The upper reaches of the river is not as good as the seed material. Better than mountain materials. Its characteristics are closer to the original jade mine, the edge of the jade is slightly rounded and the surface is smooth. It is mostly distributed in the middle and lower reaches of the riverbed, and the jade is exposed to the surface or buried underground. Fourth, Gobi materials It is formed on the Gobi material and Hetian jade. Because of the harsh natural environment in the Gobi area, the jade is more cracked, but the hardness is very high and the oil is better. Regarding the source of Gobi materials, it is said that after the river is dried up, the seed material is exposed to the ground; it is also considered to be the jade material formed by the falling of Hetian jade during transportation. The amount of Gobi material is extremely rare. With the increase in the price of Hetian jade seed material in recent years, there are more and more seed-seeding phenomena. Let's say a few judgments about the characteristics of Hetian jade seed material, in case it is not the real seed. First, the shape: the bulk of the seed material is generally not too large, the shape is similar to pebbles, no angular, round and smooth, the most common seed material is a few kilograms, and then it is rare, after thousands of years of picking The blockiness of the seed material in the river channel has become smaller and smaller; Second, cracks: People often say "ten seeds and nine cracks", basically there are many cracks on the surface of the seed material. This is because the jade is caused by collision under the river water scouring. The crack is the sputum of the seed material, but it is also important when distinguishing. feature. Third, the texture: Hetian jade seed material texture is more delicate and dense than the mountain material, because under the power of the river, the looser part of the jade is taken away, leaving the hardest part of the jade, and the river Rushing is equivalent to long-term friction, making the jade more oily and compact. 4. Sweat pores: Sweat pores refer to small pits distributed on the surface of Hetian jade. The distribution of such small pits is natural and uniform, and the gloss inside and outside is such that it cannot be faked. It is an important basis for identifying seed materials. 5. Skin color: Most of the seeds have a skin color, and now the skin color is higher than the same quality jade material.
