seam lines
- Scope note
- Faintly raised lines that form at the joints between mold sections when a molten material or slurry is poured into a mold. Seam lines are found on plaster or wax casts as well as on bronzes cast in piece molds. In ancient Chinese bronzes, some seam lines were exaggerated and integrated into the design of the casts. The term also refers to the line along which the pieces of a refractorypiece mold join, which is the locus of the line that forms on a bronze. Depending on how well the piece mold pieces fit together, the seam line may be more or less raised. More extreme flashing occurs with ill-fitting pieces.
