10. Surface treatment and heat treatment: The piece is sandblasted to remove every speck of investment. The sprues and pour spout are cut off and the nubs ground down, and any mold marks or other blemishes polished away ("chasing" the bronze). If the sculpture was cut into pieces to be cast, it is welded together and weld marks ground off. The welds create bumps and a dark rainbow hue on the bronze, and these nubs and color are also ground off. At this point, the bronze is a bright brassy color.
