ABSTRACT:
A method is described of producing an elongated glass body, particularly a preform for SiO.sub.2 -base optical waveguides, in which starting glass powder material is shaped to a porous body and the latter is sintered to form a glass body. In order to obtain uniform density throughout the porous body, the starting glass powder material is filled into and simultaneously compacted in a mold. Subsequently, the powder material compacted during the filling is consolidated by a heat treatment to result in the porous body. Molds of different design for the production of tubular or rod-shaped porous bodies are described.
