A glass-fiber bushing including a bottom tip-plate and side walls surrounding the bottom tip-plate forming a container for molten glass. The bottom tip-plate including a plurality of tips arranged to permit molten glass to flow there through to produce a multiplicity of individual molten glass streams from which glass fibers may be formed. The glass-fiber bushing includes at least one tip-plate thermocouple having a platinum tube housing, a pair of thermocouple wires transversing the tube housing and terminating in a weld junction. The tube housing, thermocouple wires and the weld are attached directly to the tip-plate such that the thermocouple junction is formed directly at the tip-plate surface.
