FLAME HYDROLYSIS MANDREL AND METHOD OF USING Abstract of the Disclosure There is disclosed a method and apparatus for pro- viding optically pure glass blanks, tubing, crucibles and the like for use in forming optical waveguides, lenses, prisms, filters, lamp envelopes and the like. A glass layer is formed at a high temperature on a mandrel which includes a support rod or tube upon which is disposed a layer of refractory metal wire, gauze, foil or the like. The mandrel is so constructed that stresses, which here- tofore have developed in the glass layer during cooling, are avoided, and the mandrel is easily removed from the glass layer, thereby forming a hollow glass cylinder that is free from cracks, checks and the like.
