A method for producing quartz glass cylinders includes producing soot bodies using depositing burners to deposit SiO2 particles for mass deposition on a rotating substrate and vitrifying the soot bodies to form quartz glass cylinders. Prior to producing the soot bodies, the following steps are carried out: producing first and second test soot bodies, determining the density distribution of the first test soot body in the axial direction; vitrifying the second test soot body to generate a test quartz glass cylinder; determining the mass distribution of the test quartz glass cylinder in the axial direction; and setting the mass deposition of SiO2 particles to be deposited as a function of the axial mass distribution of the test quartz glass cylinder. As such, the mass distribution of the produced and vitrified soot bodies is improved and/or made more homogeneous relative to the axial mass distribution of the test quartz glass cylinder. |
