Abstract
A method of incorporating an additive or dopant oxide into a glass body produced by the oxidation of vaporous source material in a flame. The resultant glassy particles are deposited to form a porous preform having a uniform refractive index. During the consolidation process, the preform is subjected to an atmosphere including a drying agent which penetrates the interstices of the soot preform to simultaneously dry and dope the preform.
