The difference between filigree and relief

The difference between filigree and relief lies in the different technology.

The history of engraving technology is longer than that of filigree technology, which began in the Spring and Autumn Period and prevailed in the Warring States Period. The main methods of making decorative patterns are engraving and carving. The technical difficulty is great, and the filigree process is to combine silk and pieces into complex cultural relics by means of pinching silk, laying silk, filling silk and absorbing pearls.
