Abstract
In embodiments, a method for operating a glass manufacturing apparatus may include heating a delivery conduit with resistive windings positioned around an exterior surface of the delivery conduit, the delivery conduit extending between a mixing vessel and a delivery vessel. The method may also include injecting electric current through the delivery conduit while heating the delivery conduit with resistive windings and prior to flowing molten glass through the delivery conduit thereby increasing a temperature of the of the delivery conduit, wherein an input heat flux into the delivery conduit is greater than an output heat flux away from the delivery conduit prior to flowing molten glass through the delivery conduit.
