Abstract:
An apparatus for forming glass tubing is described. The apparatus for forming glass tubing comprises an endless former with an outer surface and an inner passage defining an inner surface. The apparatus for forming glass tubing further comprises two chambers from which molten glass may flow. One chamber flows molten glass to the outer surface of the endless former and another chamber flows molten glass to the inner surface of the endless former. The two flows of molten glass meet at the bottom of the former to form glass tubing.
Abstract:
A method of manufacturing a laminated glass article having a first clad layer, a second clad layer, and a core layer between the first clad layer and the second clad layer, by exposing an edge of the core layer. An etchant can be applied to the edge of the laminated glass article to form the recess. The recess can then be filled.
