摘要： A method and furnace for supplying glass for flat glass production in which the body of molten glass is contained in an elongate furnace chamber having melting and conditioning zones adjacent to opposite ends and an intermediate refining zone, the glass being subjected to general heating in the melting and refining zones while being substantially undisturbed in the conditioning zone, and a control column of glass being established in the refining zone by passing alternating electric current between longitudinally spaced transversely extending electrode arrays to establish a rising current or spring of glass, part of which flows horizontally upstream and part downstream at the surface of the glass to control the velocity and acceleration of glass flow in a surface layer of the conditioning zone.
