Identify Hongshan jade first look at jade

The Hongshan culture jade is rough, atmospheric, and concise. It pays attention to the overall charm and does not stick to the style characteristics of the body. It has always been a favorite of the ancient jade collection, and it also brings difficulty in identifying the authenticity. At present, the "Hongshan-style" jade articles in the hands of the market and individual collectors are conservatively estimated to be more than 300,000 pieces. How to identify the true and false, and to save the good, in addition to grasping the momentum characteristics of the overall shape, it is also necessary to Start with microscopic aspects such as ochre, shape, craftsmanship and ornamentation.

The materials of Hongshan culture jade are mainly in three categories: the first category is the amphibole jade “river abrasive”. The Hongshan jade made of this kind of material has been subjected to sputum after burial, but most of them still contain translucent yellow-green. Advocating blue and green, not only in ancient China, but also the world's other two major jade cultural centers: Mexico and New Zealand select the main standard of jade. However, slightly different from the prehistoric jade culture in other parts of the country, the Hongshan culture jade uses the river abrasive with reddish-brown hulls, in the oblique mouth shaper, hook cloud shaper, multi-joint jade, jade, Yulong, jade turtle shells and many other large pieces or round jade carvings on the edge or the table, see the deliberate remaining red and brown leather shell. The second type of jade used in Hongshan jade is leaf serpentine, which is easy to be affected by cockroaches. It is often opaque "chicken bone white" color after use, and jade dragon, jade and jade comb back are all used. The third type of jade material has greater transparency, grayish white and greenish white, with black plaques or spots. It has the characteristics of the Neolithic jade in the Baikal region of Russia and the Jilin-Heilongjiang region. See the rounded square jade and double.璧, double beast first three holes jade comb back and other types of use. In addition to the above three main jade materials, Hongshan culture also uses jade materials such as turquoise and other jade materials. Turquoise fish-shaped pendants and bird-shaped peony unearthed from the Hutougou and Dongshanzui ruins are beautifully crafted and have a turquoise black hull.

At present, the high-end imitation of Hongshan jade, which is seen in the domestic collectibles market, is mainly made of the Shiyan Yuhe abrasive and the serpentine produced from Xiuyan. The color and texture of the Xiuyan Shiyan Yuhe abrasive are very close to the unearthed Hongshan jade. After the dyeing is done, it is easy to confuse right and wrong. However, there are few red-brown hulls left in the imitations currently seen. Serpentine, the main mineral in the "Yuyan Jade", is often used to imitate the "chicken bone white" color of the jade jade, but the difference between the artificially rapid synthesis of the twilight and the five thousand years of burial Not small, it is not difficult to distinguish.
