A lightweight, precious metal containing, glass fiberizing bushing having a novel power terminal ear arrangement is disclosed. The novel terminal ear arrangement has two relatively thin ears which extend from an area located near the midpoint of each end wall of the bushing, their elongated bases lying generally in the same plane and being generally parallel to the bottom wall of the bushing. The thin ears are spaced a relatively great distance apart but yet are relatively wide. This arrangement minimizes precious metal usage but still provides uniform heating of the molten glass within the bushing.
