摘要: A glass has a basic soda-lime-silica glass portion, and a colorant portion including total iron as Fe2O3 selected from the group of total iron as Fe2O3 in the range of greater than zero to 0.02 weight percent; total iron as Fe2O3 in the range of greater than 0.02 weight percent to less than 0.10 weight percent and total iron as Fe2O3 in the range of 0.10 to 2.00 weight percent; redox ratio in the range of 0.2 to 0.8, and tin and/or fin compounds, e.g. SnO2 greater than 0.000 to 5.0 weight percent. In one embodiment of the invention, the glass has a fin side and an opposite air side, wherein the tin side of the glass is supported on a molten fin bath during forming of the glass. The tin concentration at the tin side of the glass is greater than, less than, or equal to the fin concentration hi “body portion” of the glass. The “body portion” of the glass extending from the air side of the glass toward the fin side and terminating short of the tin side of the glass.

摘要: Glasses are provided that are highly transparent and have very good resistance to solarization. The resistance to solarization is favored to a special extent by the production method. The concentrations of reduced polyvalent ion species are reduced by targeted use of bubbling with an oxidizing gas. Methods for producing glasses and to the uses thereof, particularly as core glasses in optical waveguides, are also provided.

摘要: A method of producing glass using submerged combustion melting is disclosed. The method includes introducing a vitrifiable feed material into a glass melt contained within a submerged combustion melter. The glass melt contained in the melter has a redox ratio defined as a ratio of Fe2+ to total iron in the glass melt. The method further includes combusting a combustible gas mixture supplied to each of the submerged burners to produce combustion products, and discharging the combustion products directly into the glass melt. Still further, the method includes adjusting the redox ratio of the glass melt by controlling one or more operating conditions of the submerged combustion melter selected from (1) an oxygen-to-fuel ratio of the combustible gas mixture supplied to each of the submerged burners, (2) a residence time of the glass melt, and (3) a gas flux through the glass melt.

摘要: An apparatus and method for producing a glass article includes a melting vessel, a fining vessel located downstream from the melting vessel, and a bubbling vessel that is downstream from the melting vessel and upstream from the fining vessel. The fining vessel may include at least a first zone and a second zone downstream from the first zone, wherein the average temperature of the first zone is higher than the average temperature of the second zone.

摘要: A gradient fining tank and a method of operating the tank to refine foamy molten glass is disclosed. The gradient fining tank includes a floor, a roof, and two laterally-spaced sidewalls that at least partially define an interior chamber of the tank. The floor of the tank is profiled to provide the tank with an extended shallow portion that defines an inlet to the interior chamber and a deep holding portion that defines an outlet from the interior chamber. An entry section of the floor provides the extended shallow portion of the tank and a transition section and exit section of the floor provide the deep holding portion. A depth of the interior chamber at an outlet end of the deep holding portion is greater than a depth of the interior chamber at the outlet end of the extended shallow portion.

摘要: A submerged combustion melter includes a floor, a roof, and a sidewall structure connecting the floor and roof defining an internal space. A first portion of the internal space defines a melting zone, and a second portion defines a fining zone immediately downstream of the melting zone. One or more combustion burners in either the floor, roof, the sidewall structure, or any combination of these, are configured to emit the combustion gases from a position under a level of, and positioned to transfer heat to and produce, a turbulent molten mass of glass containing bubbles in the melting zone. The fining zone is devoid of combustion burners or other apparatus or components that would increase turbulence above that in the melting zone. The melter may include a treating zone that stabilizes or destabilizes bubbles and/or foam. Processes of using the melters are a feature of the disclosure.
