ABSTRACT OF THE DISCLOSURE A laminated wall for a feeder for supplying streams of molten glass to be attenuated into filaments is provided comprising a refractory metal core having an oxygen imper- vious, precious metal layer intimately bonded thereto by hot isoststic pressing to form a laminate, the laminate having at least one aperture extending therethrough adapted to permit the molten material to flow therethrough. Methods of making such a wall and feeder and of forming glass fibers are also disclosed.
