Zusammenfassung:	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 (100) configured to supply an electric current to the vessel through the flange (100), the flange (100) including a first ring (112) extending completely around the vessel in a closed loop, the first ring (112) comprising a first portion (118) including a first thickness and a second portion (128) including a second thickness different from the first thickness, wherein the first portion (118) and the second portion (128) overlap in a plane of the flange (100) such that at least a portion of the first portion (118) is positioned between at least a portion of the second portion (128) 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. When the vessel comprises two flanges each connected to an electrode portion (116), current is more uniformly distributed about the vessel, which prevents hot spots.
