How to identify the mountain material dyed skin imitation and Tianyu seed material
When Hetian jade seed material is processed into a brand, pendant, bracelet and other accessories, it often leaves a little stone skin. This stone skin as the "identity card" of the seed material is also an important reference in the identification. After some of the seed material has been processed, the original skin is completely removed, and sometimes a small piece is dyed by artificial dyeing at the edge to indicate that the material is a seed material.
The cause of Hetian jade seed material
The Hetian jade pieces rolled down the mountain, entered the water with the river, and passed through the Yulong Kashi River for hundreds of years or even tens of thousands of years to form a smooth surface seed. The surface reacted with the minerals in the water to form a layer or Thin or thick skin.
Mountain material for leather imitation seed
Because of the high price of Hetian seed material, some people use the mountain material with better texture. After carving, use the method of making skin to imitate the seed material, thus selling a higher price. In fact, this situation is a superfluous addition to the paintings. Some of the jade is fine and the color is white. The texture of Hetian Yushan material itself is already good. It is not necessary to dye the skin to imitate the seed material.
Different from the real seed stone skin, the seed material imitation by the dyeing method has the following differences:
After long-term erosion and friction, the skin color of the seed material forms a slightly thick and transitional stone skin, while the artificially dyed stone skin is thin and has no thickness.
The color of the leather is often deep in the cracks, and the color will break into the jade. The artificial dyed skin is evenly colored and floats on the surface of the jade.
