Abstract
The invention relates to a method for producing glass on a metal melt and can be used for improving the quality of float glass. The invention makes it possible to increase the quality of the lower surface of the float glass by removing micro-defects. To do this, a glass strip is raised above draw-in shafts of a slag chamber and kept in a raised position during transport in the slag chamber area by reducing the atmospheric pressure above the glass strip in relation to the pressure acting on the glass strip from below.
