MANUFACTURE OF GLASS BODY WITH BONDABLE LAYER

摘要

A process for the production of coated glass bodies in which a glass layer is provided by a cycle including applying a glass forming material on a surface of a rotating body and transforming the glass forming material into the glass layer by locally heating a zone of the body and moving the local heating zone along the surface of the rotating body characterized by changing either the direction of rotation or initial point of commencing the rotation or both during the commencement of each cycle so that the effect of anisotropy of the plurality of glass layers is largely eliminated.
