ABSTRACT:
The disclosure embraces a method of and apparatus for processing heat-softenable material, such as glass, involving treatment of a surface of a substrate or body at which the glass is present such as the surface of a glass stream feeder at the stream delivery region, the method and arrangement involving burning or combusting a combustible carbonaceous material in an environment at the stream delivery region under conditions yielding the formation and deposition of particles of carbon on the surface, the carbon promoting separation of the glass from the surface thereby minimizing or eliminating the tendency for the glass to flood the surface.
