How to identify the authenticity of Ming Dynasty jade through Qin color?

1. Comparison of jade raw materials in the Ming Dynasty and materials used in modern imitation jade.

In the Ming Dynasty, jade materials were mainly Xinjiang Hetian jade, in addition, jade materials such as white jade, topaz, jasper, and black jade were also widely used. Generally, high white jade is used for the processing of official products and fine products, and the rest are folk jade. Qing Dynasty jade generally said that the craftsmanship of good jade quality was also exquisite, and the craftsmanship of poor jade quality was relatively general.

Jade with willow cracks, dirt and skin is mostly used for the processing of general jade and antique jade. In addition to the use of a small amount of high-white jade materials to make jade pendants, jade plaques, etc., modern jade production rarely has large materials or large materials to make antique jade. The more extensive is the use of green and white jade, old materials and other jade materials.

Due to the difficulty of the material, counterfeiters often use newly developed substitute materials, which are significantly different from Hetian jade in terms of jade structure, hardness and density.

2. Comparison of the accuracy of jade-making equipment in the Ming Dynasty and modern imitation jade-making equipment.

In the Ming Dynasty, there was no electric device for jade-making equipment, let alone a continuously variable speed device, and the material, structure and accuracy of the equipment were relatively primitive. Due to the low degree of mechanization of the equipment and the poor material structure of the equipment, it will inevitably lead to the self-wear of the equipment and materials, which will make the accuracy and stability of the equipment poor, and the grinding processing efficiency will be low. Therefore, large process errors are unavoidable process defects and process characteristics in jade processing in the Ming Dynasty.

This defect and characteristic is clearly reflected in the artistic effect of jade, which can be found in the Qing Dynasty jade, and there are many errors in its process accuracy, such as the error in symmetry, the error in line grinding and parallelism, and the error in grinding the base surface, which also fully shows the level of jade-making equipment and technology in the Ming Dynasty.

3. Comparison of Ming Dynasty jade and modern imitation jade paintings.

Calligraphy and painting in the Ming Dynasty not only inherited the traditional art of painting, but also created and developed the artistic style of the era, and continued to influence other art categories. The art of jade painting is to fully reflect the history and culture of the Qing Dynasty with the help of various artistic styles of the Qing Dynasty and the unique expression of jade, so the painting design of jade in the Ming Dynasty has a strong sense of the times.

Generally speaking, the soil in the north of China is mostly alkaline, and the color of jade is mostly yellow. The soil in the south is moist and acidic, and the color of the jade is mostly white. After the ancient jade is unearthed, after the human body plays, the material components in its body are nourished by popularity, and the jade will slowly recover, so that the original color of the ancient jade will undergo a wonderful change, showing a colorful and rich color.

1. The jade of the Ming and Qing dynasties was mainly based on Hetian jade, and of course other jade materials were also available. 2. The jade of the Ming and Qing dynasties has belonged to the stage of folk jade, and the style of jade has a meaning, mostly with auspiciousness, many sons and blessings, harmony and other themes. 3. The authenticity of jade in the Ming and Qing dynasties is mainly judged from many aspects such as pulp, color, workmanship, shape, jade quality, and background of the times, which requires a lot of practical experience.

3.Knowledge of the maintenance of ancient jade.

There are many regions in the world where jade is produced, and jade is also divided into nephrite and jadeite. Chinese jade, which we generally call nephrite, belongs to amphibole, but there are tremolite, anthophyllite, blue amphibolite, actinolite, etc. in the hornblende stone family, and they themselves are also soft and hard.

Summary. "Qin color" is an alternative color that is different from the original color of jade after it is buried in the soil and the elements in the soil are acted.

"Qin color" is an alternative color that is different from the original color of jade after it is buried in the soil and the elements in the soil are acted.

There are two definitions of monochrome Qin can be repentant: to maintain the same color as the face and color of the essence of jade, that is, the primary and secondary colors are the same color. In addition to the essential color of jade, a color other than the essence of jade is called monochrome, which is also a color that exists opposite to the natural color of jade.

Multi-color Qin: contains two or more colors, commonly understood as: rose red for potassium manganese, red for rust, yellow for chromium, green for copper, black for gold (or mercury), white for water and other worldly suspicions, by a variety of minerals after the infiltration, the color of the town return stove is also combined with each other.

The difference between the color of Qin color and the natural color of jade: Qin color - in addition to the natural color of jade, it is the color of Li Bisheng; The natural color of jade, that is, the primary color, refers to the color of the jade itself; The transition color is the color produced between the natural color of jade and the color of Qin, which can also be called the intermediate color and intermediate color, and can also be explained by the brightness of the color.

Modifiers of Qin color: such as chicken blood red, decay flower faint yellow, crab roe green, parrot green, eggplant purple, black lacquer ancient, fish belly white, etc. are all words that modify Shiqiao, which has nothing to do with the essence of Qin color.

Summary. 1. Ancient jade is buried underground, and is disturbed by the calcium substances in the groundwater and soil for a long time, forming a layer of white shell on its surface, and the length of burial time is different, and the calcification layer is thin and thick, and some ancient jade will even be completely calcified, showing white bones, commonly known as "chicken bone white" in the industry, and the typical Liangzhu culture jade is the representative.

2. In ancient times, there was a custom of storing mercury, believing that mercury could prevent the corpse from decaying, and the mercury came into contact with the burial jade, leaving a black mark, which Heiqin called "mercury Qin".

3. Jade and iron are buried with them, and the brownish-red color formed on the jade after the iron is rusted. This kind of Qin color has been produced after the appearance of iron tools, from the Spring and Autumn Period and the Warring States Period to the Ming and Qing dynasties unearthed jade, there are Tieqin found. Tieqin is sometimes similar in color to cinnabar, but it is not difficult to distinguish after careful observation

The color of Tieqin is dark, and the color of cinnabar is reddish; After the iron is corroded, it is mixed with the liquid in the tomb, and the erosion of the jade is relatively deep, often deep into the texture; Most of the cinnabar is bonded and floats on the surface, and the skin is shiny.
