In a specific embodiment described herein there is disclosed a novel method and apparatus for producing glass fibers which includes the steps of issuing a stream of molten glass, attenuating the stream into a fiber, supplying heat to the feeder, regulating the amount of heat supplied to the feeder to maintain the molten glass at a desired temperature, and controlling the environment in a zone adjacent the stream and feeder to assist in fiber formation. A predetermined change in the effectiveness of the environmental control is detected and the effect of the regulation of heat supplied to the heater is modified to change the total amount of heat supplied in response to the detection of the predetermined change in the environmental control.
