Abstract
The invention concerns the use of a convexing/tempering installation for the manufacture of flat sheet glass or, in general, of glass not bent into convex shape on said installation. It proposes passing glass plates are passed through a conventional convexing/tempering installation, omitting the convexing operation, providing additional heating in the space initially set aside for convexing and/or modifying the tempering conditions initially provided for glass bent into convex shape in said installation. It makes it possible to take advantage of a given convexing/tempering installation for manufacturing tempered flat sheet glass or for heating glass plates with a view to having them bent into convex shape in another installation.
