Abstract: In a known melting crucible for use in a crucible drawing method, it is provided that the interior face of the crucible wall facing a crucible interior space is covered at least partially with a protective layer made of a noble metal. The known melting crucible does have good corrosion resistance with respect to the quartz glass melt, but the material costs are high because of the expensive coating metals. In order to provide a melting crucible for use in a crucible drawing method for quartz glass that exhibits good corrosion resistance at low material costs, it is proposed that the protective layer (2) be composed of a gas-tight, oxidic material that is not subject to a phase transition in the temperature range of 20° C. to 1800° C., and that the crucible interior space (17) have a gas space (17) above the quartz glass mass (27) to be held, and that the protective layer (2) be provided exclusively on the surface of the melting crucible interior face adjacent to the gas space (17).
