Yin engraving and Yang engraving are two basic methods of traditional carving in China. Sculpture is to carve the three-dimensional lines under a plane object with strokes. The intaglio is concave. Relief is a sculpture term, which refers to a convex shape and a three-dimensional line that displays strokes on a plane object. Yin engraving is mainly used for seal cutting, calligraphy and painting, calligraphy and paper cutting. Most other uses use positive engraving.
Precautions and key precautions for sealing:
There are three main materials for ancient seals: stone, wood and copper. The copper seal has a long preservation time, but it belongs to metal and is harmful to human body for a long time. Wood is easy to wear and tear, which is not conducive to long-term preservation. Therefore, the best materials are stones, such as Qingtian stone, Shoushan stone, Balin stone, bloodstone and Xiaoshanhong, all of which are very good materials.
It is generally recommended that you engrave the seal script, not the official script, regular script and cursive script. With Xiao Zhuan, it is visually atmospheric and cultural, and Xiao Zhuan is slightly older than us. If your name is engraved, the three-character name is the name plus the word "seal"; If it's two words, just engrave the name directly.
