A glass melter (30) having a mixing impeller (34) for converting a feed stre am (38) supplied to a vessel (32) into a vitrified glass melt (50). Heating means such as electrodes (36) or a gas burner (58) are used to heat the glass melt (50). Electrode (36) ar- rangements are proposed for minimizing current flow through the impeller (34 ). Current flow through a special continuous circu- lar impeller or conical pump (70) is disclosed. A cylindrical vessel (98), triangular vessel (94), square vessel (32), and hexagonal vessel (96) are disclosed. Methods of processing particular waste streams ar e disclosed including coated mineral fibers, fly ash, radioactive material, chemical waste and the like.
