Abstract
A soot glass deposit body is manufactured by placing a starting rod and a burnerfor producing glass particulates in a reaction container, introducing a source material gas to the burnerthrough a supplying pipe, producing glass particulates by a pyrolytic oxidation reaction of the source material gas in a flame formed by the burner, and depositing the produced glass particulates on the starting rod. At the time, the source material gas to be supplied to the burneris a siloxane, the burneris heated so that temperature of the burnerfalls within the range of from −30° C. to +30° C. relative to the boiling point of the siloxane, and also temperature of the supplying pipe is controlled within the range of from the boiling point of the siloxane to the boiling point plus 30° C.
