In order to increase the price of jade, some black-hearted antique dealers often use various means to make jade artifacts old. Now several kinds of pseudo-methods are revealed to prevent Tibetans from being deceived.
Old oil: It is said that there is a kind of rainbow grass in the deep mountains of Gansu, which is made into juice, mixed with a little sand and mixed well, then the new jade is immersed, baked with fresh bamboo branches, and the grass juice penetrates into the jade texture. In the middle, it shows chicken blood red.
New oil extraction: This method is suitable for stone jade with poor quality of stone. Choose red wood chips or ebony chips into the water, then put the stone jade into the soaking, use fire to dry, the juice can penetrate into the jade texture, and the stone is red. Or black.
Pseudo-lime ancient: There is a jade in the ancient jade, commonly known as "chicken bone white", which is due to the fact that Ziyu is exposed to fire. Wherever the jade passes through the fire, it turns white and is shaped like lime. The jade made by this method, although similar in color, has a fire crack, but the ancient jade is crack-free.
Yang Yu: Cut the legs of live or live sheep, and fill the small pieces of jade into the suture. After several years, the blood is immersed in the jade, posing as the red silk in the ancient jade, but this jade has no ancient jade temperature. Quiet, it seems to be dry.
Dog jade: kill the dog, cut open the abdomen, when the blood of the dog is still hot, the jade is placed in the dog's abdomen and sutured, buried in the ground, and taken out after a few years, there is a blood spot on the jade. But compared with the real ancient jade, with the color of the new jade and the traces of the carving.
Meiyu: Use loose jade material, such as stone or jade, which is heavy in stone. It is cooked with heavy ebony water and repeated several times. The loose land is soaked in ebony water to reveal water immersion marks. The law is colored to imitate the "water puddle ancient", but not as natural as the ancient jade.
Wind jade: Use the heavier jade stone. After cooking with ebony water and thick gray water, place the jade on the cold wind and snow, so that the hard jade will freeze and crack the texture like hair. Finally, It is also colored with the "extraction method" to pretend to be "cow hair" ancient jade.
Rust: Mix jade with iron filings and hot vinegar, then bury it in a damp underground for a few days, and take it out to the main road for several months. The jade has a deep red orange peel pattern due to the corrosion of iron filings, and has soil spots that are difficult to eliminate. However, the red color of this fake ancient jade is relatively shallow, and the gray spots and red will fade in a little longer time.
