Up knowledge: the ancient jade has the knowledge

古玉沁色

"Twilight" is an alternative color that is produced by the jade being buried in the soil and the elements in the earth are different from the original color of the jade. "Twilight" is often an important feature to identify the price of ancient jade and its authenticity. It is like the signature of ancient jade. Modern people can't use the power of powerful electric hand tools to copy, everything is naturally formed.

Due to the different materials contained in the soil in the burial area, the length of burial is different, so the color of the jade is not the same, and the color is ever-changing. In the "Yu Ji" of the Qing Dynasty, Chen Yuanxin made a detailed classification of the jade's twilight. Among them, there is such a record: "It is difficult to deeply test the origins of the various colors, and the total name is the thirteenth color."

Twilight color

Monochrome enamel can be defined in two ways: to maintain the same color as the jade essence, that is, the original and secondary colors are the same color. A color other than the color of jade essence is called a monochrome enamel, which is also a color existing opposite to the color of jade.

Multi-color enamel: contains two or more colors, usually understood as: rose red is potassium manganese bismuth, red is rust 沁, yellow is chrome enamel, green is copper enamel, black is gold (or mercury) 沁, white For leeches, etc., the colors produced by the infiltration of various minerals are also combined under the action of mutual matching.

The difference between the color of the ochre and the color of the jade: the 沁 color - the color other than the color of the jade is the secondary color; the color of the jade - the original color, refers to the color of the jade itself; the transition color - the color of the jade and the color The color produced between them can also be called inter-color, intermediate color, and can also be explained by the brightness of the color.

Modifiers of ochre color: such as chicken blood red, sassafras yellow, crab green, parrot green, eggplant purple, black lacquer ancient, fish belly white, etc. are all modifiers, which has nothing to do with the essence of ochre.

Clever and twilight

Since the Song Dynasty, the antiques (pretending to be false) have become more and more popular. In addition, there are more and more leather and skillful crafts in the jade. The modern pseudo-personalists have made full use of this point to give people a recognition in the ancient jade. There have been many difficulties added. However, if we carefully examine it, in addition to the comprehensive processing technology, scoring features, and the shape and decoration factors, we can still find the difference between the color and the color.

Border material, primary color and earthy color

The former has two kinds of monochromatic and multi-color, which is formed during the jade mineralization. The nature is very stable and there is no trick; the latter is the secondary change after entering the soil, there are tricks, and there are more between the twilight and the original jade. There is a clear transitional dizziness phenomenon.

Leave skin, sugar and ochre, sugar 沁

On the prominent point of the carving performance of the object, the original jade sugar part is also related to the theme of the sculpture; while the ochre and sugar mash are naturally formed after the soil is placed, and the distribution is not transferred according to the will of the work, not only at the prominent point. Oh, and the transition phenomenon.
