An apparatus (10, 100, 200, 300, 400, 500, 600) is provided for supplying molten glass material to one or more bushings (50) or spinners. The apparatus (10, 100, 200, 300, 400, 500, 600) comprises a melter (20, 120, 220, 320, 420, 520, 620), delivery equipment (30, 130, 230, 330, 430, 530, 630) and a forehearth (40, 140a, 140b, 240a, 240b, 340, 440, 540, 640). The melter (20, 120, 220, 320, 420, 520, 620) provides a main stream of molten glass material. The delivery equipment (30, 130, 230, 330, 430, 530, 630) receives the main stream of molten glass material from the melter (20, 120, 220, 320, 420, 520, 620) and transports the stream to a receiving station. The forehearth (40, 140a, 140b, 240a, 240b, 340, 440, 540, 640) defines the receiving station and comprises a receptacle (42, 541) having a length, a width and a height. The receptacle (42, 541) includes two or more columns (46a, 46b, 346a, 346b) of openings (44a, 44b, 344a, 344b, 544, 644) spaced a given distance from one another along the width of the receptacle. Each column (46a, 46b, 346a, 346b) includes at least two openings (44a, 44b, 344a, 344b, 544, 644) through which molten material passes from the receptacle (42, 541) to the bushings (50) or the spinners.
