Gao Gu jade, a kind of jade with profound historical and cultural connotations, has attracted much attention due to its unique color characteristics. Dipping color, also known as dipping color, is the color change of jade surface after a long period of natural oxidation, soil and water erosion, human use and other factors. This change not only enriches the visual effect of jade, but also becomes an important basis for identifying the authenticity of ancient jade and evaluating its value.
First, the cause of the formation of color
The formation of color is a complex process, which can be caused by a single factor or a combination of factors. Common causes of color include the texture of the jade itself, the burial environment, soil pH, temperature and humidity, etc. For example, iron-rich soils may cause a red or yellow discoloration on the surface of jade, while acidic soils may give the surface a green or black discoloration.
2. Types and characteristics of the color
1. White Qin: White Qin is the most common color in ancient jade. It usually appears as white spots or patches on the surface of the jade, and some may also form textures. The formation of white qin is related to the calcium component in jade, and after a long period of oxidation and erosion, the calcium component is gradually precipitated to form white qin.
2. Black Qin: Black Qin usually appears as black spots or patches on the surface of jade. The formation of this color is related to the presence of manganese in the soil. In the process of long-term erosion, manganese gradually penetrates into the jade and reacts with other elements in the jade to form black Qin.
3. Green Qin: The formation of Green Qin is related to the copper element in the soil. When jade is buried in copper-rich soil for a long time, copper will gradually seep into the jade and react with other elements in the jade to form a green tin. Green stains usually appear as green spots or patches on the surface of jade, and some may even form textures.
In addition to the above three common colors, there are also various types such as red and yellow. These colors not only enrich the visual effect of ancient jade, but also become an important basis for identifying its authenticity and evaluating its value.
3. The value of Qin color and ancient jade
As a natural feature of ancient jade, it is of great significance for evaluating its value. On the one hand, the color can prove that jade has undergone natural oxidation and erosion for a long time, and has historical precipitation and cultural connotations. On the other hand, Qin color can also be used as an important basis for identifying the authenticity of ancient jade. Genuine ancient jade often has a unique color, and forgeries often have difficulty mimicking this naturally occurring color.
In addition, the color of Qin also has a certain impact on the market of ancient jade. Generally speaking, ancient jade with its unique color characteristics tends to be more favored by collectors, and its market is relatively high.
In short, as a natural feature of ancient jade, Qin color not only enriches the visual effect of jade, but also becomes an important basis for identifying its authenticity and evaluating its value. For collectors and enthusiasts, understanding and mastering the color characteristics of ancient jade is the key to better appreciate and identify this ancient jade.
