ABSTRACT:
Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source, and a second orifice vertically spaced beneath and aligned with the first orifice. A chamber surrounds the second orifice and communicates with the second orifice through a metering gap between the first and second orifices. Casing glass is delivered from a second source to the chamber such that glass flows by gravity through the orifices from the first and second sources to form the cased glass stream. The first and second orifices are disposed in respective first and second orifice rings of refractory composition. The first orifice ring has a peripheral flange and an interior passage for glass flow from the first source to the first orifice. The second orifice ring has a peripheral ledge on which the flange rests, and a pocket for cooperating with the underside of the first orifice ring to form the chamber that surrounds the metering gap. At least the underside of the first orifice ring, and preferably the underside of the first orifice ring, the first orifice and the glass flow passage through the first orifice ring, includes a continuous layer of high-temperature erosion-resistant metallic composition such as platinum.
