Abstract: 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.

Abstract: A process for obtaining a glass sheet including antimony oxide, the process including a step of melting a batch mix, a step of transporting the molten glass to at least one forming device, and a forming step, in which glass frit including a weight content of antimony oxide between 2 and 30% is added, concurrently or alternately, to the batch mix, during the melting step, or during the step of transporting the molten glass to at least one forming device.

Abstract: The subject of the invention is a glass sheet, the light transmission of which is greater than or equal to 89% for a thickness of 3.2 mm and the chemical composition of which comprises bismuth oxide in a weight content between 0.05 and 1%.
