ABSTRACT:
A method for the manufacture of glass, in particular, for glass fibers for optical communications, is provided, wherein glass particles on a substrate rod rotating about its axis, are deposited from a flame. In order to increase the yield of the deposition, two or more substrate rods are arranged at a distance from one another such that, between them an interstice with a diameter which is preferably smaller than the diameter of the free flame remains free and the flame is conducted through the interstice. By this method it is possible for the flame to be surrounded by substrate surfaces from several sides, as a consequence of which an increase in the yield of the deposition rate results.
