Abstract: Various embodiments of the present invention relate to glass fiber forming bushings, to methods of controlling the temperature of bushings having multiple segments, to systems of controlling the temperature of bushings having multiple segments, and to other systems and methods. In one embodiment, a method of controlling the temperature of a bushing having multiple segments comprises forming a plurality of filaments from a bushing comprising at least two segments, gathering the filaments into at least two ends, measuring the size of each of the at least two ends, comparing the measured size of the at least two ends to a desired end size, adjusting the amount of current passing through the at least two bushing segments in response to the end size comparisons.
