Abstract
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.
