On the manifestation of jade carving technology

On the expression of jade carving technology

Summarize China's jade carving skills, mainly as follows:

Line engraving: that is, engraving patterns with single lines.

Thin meaning: a very shallow relief with painting significance.

Circular sculpture: it is a three-dimensional sculpture.

Relief: that is, carving a raised pattern or shape on a plane.

Internal carving: it is a jade carving technique that deeply carves round carving and relief modeling from the inside of jade material.

Concave carving: Contrary to relief, the design or shape of a concave is carved on a plane. Also known as yin carving.

Clever color carving: that is, the clever use of multi-color jade materials, so that different colors are properly distributed in the parts needed by jade carving, so that the works have a sense of harmony.

Architectural sculpture: also known as through carving, that is, carving is not limited to one side of the jade material, but penetrates the jade material and hinges the carving, so that there are many spaces connected on both sides in the jade material. In addition, there are many technical terms of jade carving techniques. When we read jade carving books, especially ancient jade books, if we don't understand its meaning, it is difficult to learn appreciation methods according to its meaning. Such as double groove male pattern or double groove line, female engraving, male engraving, wear-reducing male pattern and so on.

Double groove male pattern, also known as double hook female pattern, is a carving technique that only appeared in Shang Dynasty. It's a side-by-side double-line intaglio. It looks like a positive line, but it's not. Instead, the two sides of the line are shallowly ground to remove two depressions. They are shallow grooves with inclined angles, not straight walls, so they look like male reliefs. This feature is directly related to the grinding wheel at that time. Even if you copy the current processing tools, it is easy to make mistakes in details.

Relief relief pattern, also known as relief, refers to a kind of shallow relief, and the decorative pattern is shallow and convex on the ground (plane). This positive pattern is achieved by grinding the ground, that is, reducing the ground. This carving technique has been found in Shang jade articles.

Literally, it is easier to understand intaglio engraving and positive engraving. A concave carving is a concave carving, and a male carving is a convex carving. It's just a description of the decorative patterns, and it doesn't mean to ponder the techniques. Different times may have different methods and characteristics.

In a word, all kinds of jade carving techniques have interpreted magnificent oriental art for the world.
