Abstract
An electric open-top melter for use in the manufacture of mineral fibers, such as fiberglass, is provided with a side-discharge outlet. The side-discharge outlet allows the melter, conditioner/refiner, and forehearth to all be located on substantially the same level, thereby allowing molten glass to flow from the side of the melter, through the conditioning zone, and into the forehearth from which spinners produce glass fibers or the like. Isolation members are provided in the conditioning or refining area so as to enable molten glass therein to be isolated from the melter and forehearth when the molten glass level is lowered below the tops the isolation members.
