Zusammenfassung:Glass forming devices can comprise a first outer surface of a first wall, a second outer surface of a second wall, and a heater. Glass forming methods can comprise flowing a first stream of molten material over a first outer surface of the first wall and flowing a second stream of molten material over a second outer surface of the second wall. Methods can further comprise drawing a glass ribbon. Methods can also comprise heating the first wall with the heater to heat an inner portion of the first stream of molten material contacting the first outer surface of the first wall to maintain a viscosity of the inner portion of the first stream of molten material below the liquidus viscosity of the first stream of molten material.
