摘要： An energy-efficient device for refining a glass melt to produce a glass and/or a glass ceramic is provided. The device includes a refining crucible defined at least by lateral walls with a metallic lining as a melt contact surface, so that a melt refining volume is defined by a base surface, a top surface and a circumferential surface; at least one heating device that conductively heats the lining by an electric current in the lining, so that the melt is heated through the lining, the heating device and the lining are connected to one another by a feeding device. The feeding device establishes contact with the lining so that an electric current runs from the top surface to the base surface or from the base surface to the top surface, at least in sections of the lining.

摘要： A method of manufacturing a glass article includes flowing molten glass through a first vessel to a downstream second vessel, the molten glass flowing through a conduit connecting the first vessel to the second vessel, the first vessel and the conduit defining a continuous free volume above a free surface of the molten glass extending into at least a portion of the conduit. The method further includes venting a first atmosphere contained in the free volume to a second atmosphere external to the first vessel through a vent tube connected to the conduit proximate a top of the conduit and above the free surface, the vent tube extending downward from the conduit to a distal end of the vent tube along a longitudinal axis at an angle a relative to horizontal and providing fluid communication between the first atmosphere and the second atmosphere.

摘要： The present invention is directed toward a method of reducing contamination of a glass melt in a stirring apparatus by an oxide material. The oxide material, such as platinum oxide, may be volatilized by the high temperature of the glass melt, and then condense on the inside surfaces of a stirring vessel, particularly the stirrer shaft and surrounding surfaces of the stirring vessel cover. A build-up of condensed oxide material may then be dislodged and fall back into the glass melt. Accordingly, an apparatus and method is provided that includes a heating element disposed adjacent an annular gap between the stirring vessel cover and the stirrer shaft. The heating element heats a surface of the stirring vessel cover bounding the annular gap and prevents condensation of volatile oxides that may flow through the annular gap.

摘要： Disclosed is an apparatus and method of making molten glass. The apparatus includes a vessel for conveying the molten glass and at least one flange configured to supply an electric current to the vessel through the flange, the flange including a first ring extending completely around the vessel in a closed loop, the first ring comprising a first portion including a first thickness and a second portion including a second thickness different from the first thickness, wherein the first portion and the second portion overlap in a plane of the flange such that at least a portion of the first portion is positioned between at least a portion of the second portion and the vessel wall, and neither the first portion nor the second portion extends completely around the vessel. Also disclosed is a method of making glass using the disclosed flange.
