There are several common methods for pseudo-manipulation and identification of jade artifacts in the past:
(1) Ancient jade change
The ancient jade pieces that have been handed down from ancient times are full of primitives, so the pseudo-persons will be transformed into sporadic small pieces according to the shape and ornamentation of the original objects, or the remnants will be trimmed. Traces, focusing on dyeing and matting.
(2) After the ancient jade carving
It refers to the processing of ancient jade that is not in shape or irregular in shape and incompletely carved. The ancient jade ware with a plain or one side ornamented with a plain surface will be re-discussed and carved. The ancient jade articles such as jade axe, jade, jade, jade and jade are more used.
(3) Artificial dyeing
It is mainly used for the antique counterfeiting of new jade. Among them, burning, roasting, boiling and frying are the main methods of artificial dyeing, and they can be used alone or in combination. The most common are:
Oil extraction method
Also known as the frying method, the jade is to be dyed in a frying pan. The length of the frying time varies with the length of the jade, and the surface of the jade has different shades of red, orange and red.
2. Acid etching
The antique jade is placed in a strong acid, causing unevenness on the surface of the jade. Some of them show white bone after being corroded by strong acid, and some are dyed as needed.
3. Fading method
The antique jade will be rubbed into the bran, and the oil of the bran will be used in the friction to evenly fade, so that the new jade will have the soft and moist luster of the ancient jade.
4. Imitation cow hair pattern
In the winter lunar month, immerse the jade that has been made with thick gray water or thick ebony water, cook it for two days in a simmer, take it out and put it outside in the snow, and make the jade pattern freeze and crack like a fine hair. Crack marks, then add a little cinnabar to the yarrow juice, ignite the barbecue with bamboo branches, or put the jade in the ebony or red wood chips, and the red cow hair pattern will come out, commonly known as "wind jade".
5. Imitation chicken bone white method
In the ancient jade, you can see the white jade like "cooked chicken bones", commonly known as "lime æ²", which is caused by the fire of the ground and is extremely valuable. The forgers artificially put the jade articles made of sub-white jade, sub-Yuyan jade and other inferior materials in the fire. When the ash is hot, the water is drastic, and the chicken-bone white "ancient jade" is made, but there is no jade. The warm and transparent luster, like the decaying stone, has no aura.
6. The red spot on the ancient jade of the plaque method, commonly known as blood stasis. The pseudo method is to put the prepared jade on the fire and immediately put it into a pre-prepared dog or cat abdominal cavity, sew it firmly, bury it in the ground, and take it out after one year. The jade is bloody. There are also jade in the live leg of the sheep, and then the wound is sewed, and taken out a few years later, the jade is naturally also brought with blood, commonly known as "dog jade." If you put it in the leg of a lamb to make a blood core, it is commonly called "Yangyu".
7. Rusting method This is the method of forging soil rust in ancient times. According to legend, in the dry years, Wuxi aunt first made a rough jade, then mixed with iron filings, and quenched with hot vinegar, and then placed in a damp ground. After ten days, people were buried in the streets of the people. After a few months, they were taken out. The jade was eroded by iron filings. The orange rust was everywhere, and the rust in the lines was dark red. After boiling with water, the color will become darker and there will be soil spots, and the lime soil will not easily fade away. It is very similar to ancient jade, commonly known as “å©çŽ‰â€.
8. Forged black spot method After boiling the jade with water, mount it on the iron shovel and burn it with fire. Apply wax oil to the jade while burning, without time limit until the black spots are formed. Or wrap it in old cotton soaked, burn it with firewood, and pour it with water when it is dry. Wait until the black bones instead of floating on the surface, not white, black spots are caused.
