Abstract
In the manufacture of flat glass, molten glass is delivered along a substantially horizontal delivery path onto a pool of molten metal. A stream of molten glass is deeper along its marginal portions than its central portion in order to provide for substantially uniform flow rates across the entire stream of molten glass. A continuous ribbon of flat glass of any thickness may be uniformly formed in a very short distance extending downstream from the delivery as a result of delivering the glass in this manner.
