The engraving techniques of gold jewelry are rich and complex. The following are some detailed explanations of the main techniques:
"" : On the surface of a plain base, use various degrees of" "to outline the basic pattern. One side of the chiseling is flat and the other is curved. It varies in size, length, thickness and fineness. Generally, the curvature of the lines in a pattern is the curvature of the chiseling. This is the basic method of chiseling, which can determine the basic outline of the pattern.
Lift (platform) : Raise the pattern outline on the front of the product from the back of the object to achieve the design requirement of the chiseling effect. Select the same "last" as required by the product, lay the material sheet on the "last", and use different hammers to strike the sheet into the shape of the "last", that is, the mold. Through this technique, the pattern can present a three-dimensional effect.
Step: Chisel the parts of the product's surface pattern that need to be recessed from the front of the object to achieve the required intaglio effect as designed. This is an important technique used in chiseling to shape the concave parts, which can enhance the layering of the pattern.
Qiang: A manual technique of cutting and removing on the surface of objects. When operating, use a relatively sharp chisel to remove certain materials to express the contrast of light and shade in the pattern.
String: Operate on the back of the base material. According to the design requirements, use round head chiseling of different areas from the back of the product to raise the height of the local area. This technique is often used to adjust the convexity of certain parts in a pattern to achieve the desired effect.
Silk: It refines the structure and details of the product after the overall shape is engraved, making the lines of the pattern clear and fine. The head of a silk chisel is flat, with horizontal and vertical lines on it. There are various types such as dense and sparse, large and small. It is mainly used for engraving the hair, beard or linear patterns of people or animals, which can enhance the refinement of the patterns.
Pressing, also known as "stamping", is a process that uses molds and stamping equipment to apply pressure to the surface of gold jewelry, causing it to deform and thus obtaining relief patterns. When combined with engraving, it can enrich the shape of the jewelry.
"(qiāng) : It involves cutting and removing on the surface of an object, which can be used to express the contrast of light and shade and enhance the artistic expressiveness of the pattern."
String: Operate on the back of the base material. According to the design requirements, use round head chiseling of different areas from the back of the product to raise the height of the local area. This is often used in the areas where the convexity in the basic pattern is insufficient, and it is punched from the back to achieve the required height.
In the basic pattern, the areas that do not need to be raised are chiseled down with sand to create the basic layers of the pattern. Luohuo is also an operation carried out on the front side of the plain fetus.
The surface of the pattern is processed smooth and bright by using square, round and differentially sized chisels.
Silk: It refines the structure and details of the product after the overall shape is engraved, making the lines of the patterns and designs clearer and more refined.
