How to identify the drum material in Hetian jade?

In the Hetian jade market, the roller material and the Hetian jade seed material have similar appearances, and the colors are similar, making it difficult to distinguish. It is easy for people to be deceived. The roller seed material is cut into small pieces by a whole piece of inferior mountain jade, and is placed in a large drum with frosted particles to rotate back and forth, and the shape of the imitation small seed material is formed for a long time.

The principle is simple: the drum mimics the process of forming the stock. As the water flow rolls, the jade material collides with the hard excipients, and the surface of the raw material is collided with some uneven pits. This is the so-called "pores." In addition, the collision can sharpen the edges and corners of the mountain material and gradually form a rounded appearance.

The mountain or stone is boiled at a high temperature, placed in such a homemade shaker, sprayed with a dye, and sprayed while allowing it to absorb and rotate the iron bucket to round the stone.

There are some small, high-quality "seeds" that are processed with this small-sized grinder. Put the stone that was bought with mountain material or Qinghai Russia, and grind it with small stones to make it smooth. After the picture is colored, the seed material is sold. This "batch of seed" takes about ten days of grinding!

How to identify the roller material?

The "sweat pores" of the seed material:

There is no sweat pores is a good feature to identify the seed material. The real seed material skin is often filled with tiny sand holes like skin pores. The whole skin is moist and uneven. It is a seed jade in the river. The result of many years of barreling and sanding.

No matter how delicate the seed jade, in the natural state, after thousands of years of experience, it will form numerous small holes in his surface, very like the pores of human sweat. Generally it is not artificially forged, and it is very clear when looking at the light meter or under the magnifying glass.

The most practical way to look at the pores is to look at the surface of a seed, the concave part of the pores is thicker, the convex part of the pores is fine, and the pores from the fine to the coarse excess is very natural and uniform. Mastering this, I found the secret to see the pores of the seed.

Look at color

Hetian jade seed material has various skin types, such as red skin, yellow skin, sprinkled gold skin, autumn pear skin, etc. The color is bright and the distribution is natural; while the roller material is mostly dyed, the color is gorgeous and the distribution is too uniform, and There is a accumulation of pigments at the cracks on the surface of the jade, so sometimes the drum material may be discolored.

Look at oil

The real Hetian jade seed material has a fine structure, smooth and radiant appearance, oily foot and smooth touch, while the counterfeit roller material has different types of jade, the surface is covered with pigment, the hand feels dry, and the oil is insufficient, put the two together. Contrast, you can identify it.

Look at the feel

The natural Hetian jade seed material has a smooth and smooth appearance, and the handle feels smooth. If there is obvious fine pore skin, the hand feels a frictional feeling, while the counterfeit roller material has a smooth surface and no fine pores, and no obvious The impurities are ç‘•ç–µ, so the hand feels too smooth.
