Abstract
In a method of forming a thin sheet glass by the float process, a thin layer of molten glass is formed by making molten glass flow through a sluice formed on the surface of a molten metal bath, and the glass layer is drawn lengthways of the bath to further reduce its thickness and advance while its upper surface is exposed to a cooled atmosphere. The sluice is a vertically narrow gap between the surface of the molten metal and a lower end face of a wall extending above and transversely of the molten metal bath. By shaping a lower end portion of this wall and avoiding particularly heating the molten glass in the vicinity of the sluice, it has become possible to obtain defectless sheet glass thinner than one millimeter.
