Blue and white jade is generally made up of jade and white jade in two colors, that is, "blue and white" is the overall name for a piece of jade ink and white. This is the same as blue-and-white porcelain. Blue-and-white porcelain is generally composed of two colors, "flower" is not flower, "flower" is not color, and the actual dominant color is "cyan". Blue and white jade draws on this title, black (ink is black), white is mainly ink, white is the base or embellishment.
The composition of Hetian Qinghua seed jade and blue-and-white mountain is exactly the same. The difference is that the former is from the Karakash River Basin in Xinjiang, while the latter is from Qinghai Golmud and Xinjiang Yecheng County. The price of blue-and-white seed material is also higher than that of blue-and-white mountain material. . Their composition is exactly the same, the colors are similar, how do you distinguish them?
The most important method for distinguishing blue and white seed and blue and white mountain material is based on the distribution of ink color among them.
First, let's look at the ink color distribution of blue-and-white seed material. The ink color distribution of blue-and-white seed material is mainly cloud-like, flake-like and silky. The surface looks like it is gathered or naturally dispersed, and the ink color is relatively stable and pure.
The ink color of the blue-and-white mountain material is distributed in a point-like manner. The whole is roughly seen, and the black color becomes a block. However, if the naked eye observes it or observes it with a magnifying glass, it can be found that its ink color is densely formed by dots. And there will be some "silver sand" material (lighting sand points), which is common in Qinghai blue and white mountains, so once you find this sand point Certainly it is blue and white.
In addition, the oiliness of the blue and white seed material is relatively good, the material quality is fine, generally clear, the border is clear, and the black and white distribution of the blue and white mountain material is blurred, and the material is slightly looser and slightly dry than the blue and white seed material. If the blue-and-white material is artificially patterned into blue-and-white seed through the drum, the color of the leather part is additive, unnatural, and not as moist as the leather part of the blue-and-white seed.
