How to judge the value of ivory collection

In January 2006, the Ministry of Culture announced the list of recommendations for the first batch of national intangible cultural heritage lists. Ivory carving was famous as a folk work list. Ivory carving application for national intangible cultural heritage has made this ancient traditional art attracting attention to the world again. People who pay attention to the art of ivory carving are constantly influxing. How can they judge the size of ivory collection value for the first entry of ivory? He Zhongwei believes that the value of judging ivory collection is mainly to judge from four aspects.

1. Dynasties. Because the characteristics of ivory have always been consistent with the aesthetic values ​​of the upper society, the ivory of different ages not only represents the craftsmanship of the age, but also reflects the cultural characteristics of dynasties and nations. Therefore, according to the perspective of historical and cultural research, the longer the ivory value of the age. For example, in 1973, Yuyao, Zhejiang, was produced in Yuyao, Zhejiang more than 7,000 years ago, "ivory Shuangfeng Chaoyang" in the Hemodu culture period, and 1976 The "carved pattern inlaid ivory board unearthed from the Yin Dynasty) of Anyang, Henan Province The cup ", the" bird and beast pattern rifle "of the Tang Dynasty, as well as the value of the" ivory panels "that have been used in the Ming Dynasty and have been used in the Ming Dynasty and the status of representative officials. In addition, the Ming and Qing dynasties were the heyday of ivory carving in my country. At that time, many masterpieces were worth collecting.

2. Process. The other aspect of ivory value is to reflect its carving. Therefore, the height of the carving process also determines the value of ivory carving. The ivory carving is found to the cosmetic lady and beautiful round carved flowers in the fairy -like appearance, which has an unique artistic style of elegant, simple, fine, and vigorous. Ivory carving must be made through five processes such as chiseling, shovel, opening, grinding, and color smoke. The chisel is the shaping of the blank; the shovel, that is, fine processing; opening the face, is a meticulous expression on the face of the character; grinding, making fine polishing; color smoke, according to different requirements, dyeing the work. The carving method is also diverse, mainly using shades of relief, hollow carving and three -dimensional round carving. Generally speaking, the value of ivory carving with superb craftsmanship will rise. Because the ivory carving technology produced by the court is higher than the folk, the collection of court works is higher.

3, texture. It is mainly produced in India, Thailand, Myanmar and other places in Africa and Asia. African public elephants and mothers have teeth, and they are also longer. The tooth produced by the Eastern Africa equatorial area, nine feet long, is the largest of ivory. African ivory is mostly pale yellow, with fine texture, good luster, and high hardness, but it is easy to crack when the temperature changes. The mother of Asia does not have teeth. The color of ivory produced in Asia is relatively white, but it will gradually age after a while, yellowish color, and poor luster, and its dental hardness is lower than that of African teeth. The ivory texture is delicate, the hardness is moderate, the luster is soft, and the teeth are fine. Naturally, it is a natural good material for making high -end crafts.

4. Famous masters. Many micro -carving artists have emerged from the Qing Dynasty, among which Yu Shuo and Wu Nanyu, who were called "South Wu" by the collection world, are the most famous. Jiangnan's famous ivory micro -sculptor Yu Shuo is good at using blind engraving, that is, when the naked eye cannot be seen, it is carved with a knife with the feel. , Smooth and natural, its skills are deeply stunning. Another micro -sculptor with Yu Shuo is Wu Nanyu. Later generations commented that he "can engraved more than a thousand characters on the ivory surface of the five -point circle and has a lot of posture. It is the so -called ghost ax. " There are fewer and fewer works of such famous works. Whether from the perspective of "things and rareness" or unique to famous artists, the collection space is huge.

The ivory carving in the cost -effectiveness of materials and craftsmanship, there is room for rising. Coupled with the scarcity of ivory resources, the preciousness of the product, the limited nature of the stock, the ivory is as precious as the rhino horn product and cannot be renewed. These have reserved unlimited space for the market market.

It with the prospect of ivory carving, many imitation products appear on the market. He Zhongwei suggested that investors to identify ivory to identify ivory must be good at using small secrets. One is artificial chemical imitation. For artificially making "tooth patterns", under the observation of the magnifying glass, it will find that the pattern is too rigid and has a sense of bumps, which is easy to recognize; the weight is relatively light. The second is the bone imitation product, which generally has the bone -specific bones, but the bone and corner products do not have the natural texture of the ivory, and the overall color is also dark. Even after bleaching, it cannot reach the smooth and nourishing state of ivory, and the hardness is more crispy than ivory. The third type is the imitation of fish tooth, and the fish tooth is lighter than the ivory and the toughness is poor from the weight.

Please wait patiently.nQuestion to identify ivory pendantnWhether it is truenThe answer is good, wait a bitnHow long is the question?nAnswer to see weight, the same thing, the heavier of ivory! There are small ripples on the top. The ivory is more delicate. The ivory has a tooth pattern and the shape is cross -horizontal human shape. The teeth are thick and thin, and the bones are relatively rough! The gloss is round! Not as dry as the bones! Give people a warm feeling!nThere are some small patterns in the real ivory. Put it in vinegar for soaking overnight, it will be soft and can make fine craftsmanship. After the production, use wooden thieves to slow down the fire and cook, and it will be hard. If you do not have these characteristics, it is not a genuine ivory. Another way is to use a tadpole to cook the ivory, which will soften, and then recover with the first method.
