- Piece-mold casting served as the primary method for creating bronze vessels during the Shang Dynasty
- Process involved creating a clay model of the desired object, then covering it with sections of clay to form a mold
- Clay mold sections were removed, fired, and reassembled around a clay core, leaving a gap for molten bronze
- Decorative patterns were carved into the inner surfaces of the mold sections before reassembly, creating raised designs on the final bronze object
- Technique allowed for the production of larger and more complex bronze objects than previously possible
- Shang artisans perfected the creation of clay cores and molds, enabling the production of hollow vessels with thin, uniform walls
- Multiple-piece molds allowed for the creation of more elaborate and three-dimensional designs
