Abstract
There is disclosed a highly refractory substrate having a vitreous carbon coating formed on its surface, and a method of forming such coating by contacting the substrate, while hot, with an organic material in liquid form. In one form, the substrate is a drawn glass filament which may be coated as part of the drawing operation, and which may, for example, be an optical filament useful in an optical waveguide system.
