The invention relates to a process and a device for manufacturing molten glass comprising from upstream to downstream a furnace for melting and fining glass equipped with cross-fired overhead burners, then a conditioning basin supplied with glass by the furnace, the dimensions of this manufacturing device being such that K is higher than 3.5, the factor K being determined from the dimensions of the device. The invention makes it possible to dimension a device for melting glass so that it is smaller and consumes less energy while producing high quality glass.

Process and device for melting and fining glass

This invention concerns glass sheets made from a glass containing, in percentages by weight, from 0.85 to 2% of total iron expressed in the form Fe O , the content by weight of FeO being from 0.21 to 0.40%, said sheets having, for a thickness of from 2 to 3 mm, a factor (T ) of at least 70%, a factor (T ) less than 50% and a factor (T ) less than 25%. The sheets according to the invention are more especially intended for the production of lateral panes for automobile vehicles.
