• The Shang dynasty bronze craftsmen employed various casting techniques to create intricate and highly detailed objects
• The most common technique was piece-mold casting, which involved creating a clay model of the desired object and then forming a mold around it
  • This process allowed for the production of complex shapes and intricate decorations
• Other techniques included lost-wax casting and section mold casting, which were used for specific types of objects or decorative elements

Piece-mold casting process

• The piece-mold casting process began with the creation of a clay model of the desired object
• The model was then covered with a layer of fine clay to create a smooth surface and capture intricate details
• The clay mold was divided into sections, allowing for the removal of the clay model and the creation of a hollow space for the molten bronze
• The mold sections were reassembled and bound together, and molten bronze was poured into the mold through channels and vents
• After cooling, the mold was broken apart, revealing the cast bronze object, which was then finished and polished

Clay models and molds

• Clay models served as the basis for the piece-mold casting process and were created by skilled artisans
• These models were often highly detailed and decorated, reflecting the desired final appearance of the bronze object
• The clay used for the models and molds was carefully selected and prepared to ensure the best results
• The quality of the clay and the skill of the artisans in creating the models and molds directly impacted the final appearance and quality of the cast bronze objects
