Abstract: The invention relates to a glass production method comprising the production of a glass precursor mixture for a glass furnace, in which water, sand and sodium carbonate are mixed in weight proportions of between 0 and 5%, 40 and 65%, and greater than 0 and at most 25% respectively, and, after at least 10 minutes, calcium oxide is added in a weight proportion of between 1 and 20% of the total. The invention relates to a method for producing glass using a mixture containing, in particular, calcium oxide, and a glass melting furnace, said method and furnace using a burner with a flame directed at the glass batch.

Abstract: Installation including an industrial glass furnace (1) including a tank (2) for molten glass (3), a combustion heating chamber (4) situated above the tank (2), and a duct for evacuation of flue gases in communication with said heating chamber (4), and a stone furnace including a firing zone (21) for stone to be fired, the flue gas evacuation duct including a flue gas outlet that is connected to the firing zone (21) of stone to be fired and supplying the firing zone (21) of stone to be fired with flue gases at high temperature.

Abstract: The invention relates to a glass production method comprising charging a glass furnace with solid-state raw materials, said raw materials comprising granular glassy sodium silicate and having a moisture content of less than 1%, preferably 0%, by weight, and powdered calcium oxide.
