Abstract
The invention pertains to a stirrer apparatus for glass melts. A stirring element and a stirrer shaft are provided, each comprised of a metal or a metal alloy having a high melting point temperature. A drive shaft for the stirring element comprises a different metallic material, for example an ODS alloy on the basis of iron or nickel. The junction between the stirrer shaft and the drive shaft is located approximately in the region in which the level of the surface of the glass melt is located during use. The end portion of the drive shaft or the end portion of the stirrer shaft, which can be covered by the melt during use, are isolated by a platinum casing.
