Abstract: Methods for reducing the oxygen concentration in an enclosure including a platinum-containing vessel through which molten glass is flowing are disclosed. The methods include injecting hydrogen gas into an oxygen-containing atmosphere flowing between the enclosure and a reaction chamber. The atmosphere is heated with a heating element in the reaction chamber, whereupon oxygen in the oxygen-containing atmosphere reacts with the hydrogen. In other embodiments, the hydrogen gas and oxygen-containing atmosphere can be exposed to a catalyst comprising platinum positioned in the reaction chamber.

Abstract: A method for forming a laminated glass article may include flowing a molten first glass composition having a first R2O concentration and a first fining agent with a first fining agent concentration. The method may also include flowing a molten second glass composition having a second R2O concentration less than the first R2O concentration of the first glass composition and a second fining agent with a second fining agent concentration that is greater than or equal to the first fining agent concentration of the first glass composition. The molten first glass composition may be contacted with the molten second glass composition to form an interface between the molten first glass composition and the molten second glass composition.

Abstract: Methods for making a glass article are described that include flowing molten glass through a metallic vessel, and supplying alternating electrical currents to multiple electrical circuits, each electrical circuit including a power supply, a pair of adjacent electrical flanges connected to the power supply, and a portion of the metallic vessel extending between and in electrical communication with the pair of adjacent flanges. At least two adjacent electrical circuits of the multiple electrical circuits share an electrical flange that is a common electrical path for the two adjacent electrical circuits, the two adjacent electrical circuits being supplied with alternating electrical currents, wherein at least one of the electrical currents is cut by a phase-fired controller.

Abstract: A glass melt delivery system vessel has at least one sidewall and floor made of a refractory material, such as zirconia, and at least one electrode extending through the refractory material. The at least one electrode is configured to heat a glass melt in contact with the refractory material at an average temperature of at least about 1600 C° without exceeding a breakdown condition of the refractory material in contact with the glass melt.

Abstract: In embodiments, a melter for melting glass may include an inlet wall, an outlet wall opposite the inlet wall, and sidewalls extending from the inlet wall to the outlet wall. The inlet wall, outlet wall, and sidewalls define a glass melting space enclosed by a floor and a top. In embodiments, the inlet wall may comprise a glass contact wall comprising a glass contact surface facing the glass melting space. A superstructure of the inlet wall comprises a jack arch positioned over the glass contact wall and at least a portion of the glass melting space. A plane of an interior face of the jack arch and a plane of the glass contact surface are off-set in a horizontal direction. A vertical distance from the floor to an underside of the jack arch is less than a vertical distance from the floor to an underside of the top.
