Abstract
A nonprecious metal drain bushing for use in the start-up of a glass melting furnace. The bottom wall of the bushing is relatively wide and thick and is bent downwardly near the ends of the bottom wall to form integral terminal ears. The end portions of the terminal ears are of reduced thickness for attachment by the power clamp. The side walls coverage at an angle down to the bottom wall to facilitate flow of the molten glass through the bushing, and the thickness of the bottom wall and terminal ears is substantially greater than the thickness of the side and end walls.
