METHOD AND APPARATUS FOR FLOAT GLASS MANUFACTURE

摘要

The surface of glass is modified by migration of an element from a molten electrically conductive body into the glass, and a continuous gaseous flow in the vicinity of the glass surface emerging from contact with the molten body removes harmful vapors originating from the molten body. The gaseous flow is induced by directing a laterally elongated opening toward the glass surface and the molten body, and causing gas to be either sucked into the opening or emitted therefrom to create a gas flow longitudinally of the glass surface.
