Abstract: For improving the refractive index homogeneity of quartz glass bodies, at least one burner is disposed movably in a melting device with respect to the quartz glass object which is to be produced. The burner has three essentially concentrically disposed groups of nozzles for metering the raw material, supplying the hydrogen and supplying the oxygen. Corresponding to the changes in the distribution of OH and H2 between the center and the edge of the quartz glass object, the volumes of hydrogen and/or oxygen of the burner gases flowing change as a function of the burner position with respect to the quartz glass object in order to bury the mixing ratio in the burner gas.
