ABSTRACT:
A method for depositing glass by decomposition of glass forming compounds in the vapor phase wherein a gaseous mixture of glass forming compounds is introduced into a refractory tube, and a source of heat is applied to the tube while the tube is being rotated. The source of heat is moved parallel to the axis of the tube to provide a moving hot zone therealong and at the same time to cause a conical neck portion to develop in the tube at which deposition of the glass forming compounds takes place.
