Abstract: A low-NOx end-fired furnace for melting glass equipped with an overhead burner includes an inlet duct for oxidizer, including 15% to 30% of oxygen, in its upstream wall, a duct for receiving the combustion flue gases in its upstream wall, and a sonic injection system including at least one injector for injecting a jet of a gas at a speed at least equal to 80% of the speed of sound, referred to as a sonic injector, opening into the upstream wall or opening into the duct for receiving the combustion flue gases, the sonic injector injecting its gas counter-current to the stream of the combustion flue gases that are heading toward the duct for receiving the combustion flue gases.

Abstract: The present invention relates to a hollow glass, such as a bottle, glass, flask or pot, consisting of a glass substrate having, on at least one portion of its outer wall, a hydrophilic organic coating, for instance based on polyvinyl alcohol crosslinked with at least one acid selected from citric acid, polyacrylic acid and poly(acrylic acid-co-maleic acid). In order to manufacture this hollow glass, a solution containing the ingredients for forming the coating and at least one solvent is applied to the glass substrate by spraying, dip-coating or, when the hydrophilic organic coating is a partial coating, by spraying onto the outer wall of the glass substrate on which a mask has been applied, or by screenprinting; the glass substrate coated with said solution is dried; and the substrate is cured thermally or by UV radiation or by electron beam. It is possible to use this hollow glass for revealing a pattern thereon when said hollow glass is removed from a cold storage zone.

Abstract: A soda-lime-silica glass composition, includes the optical absorbers below in contents varying within the following weight limits: Fe2O3 (total iron) 100 to 1600 ppm, Cr2O3 20 to 100 ppm, S2? 10 to 50 ppm. The composition has a redox, defined by the molar ratio between the ferrous iron and the total iron, of less than 0.7.
