Filed:
Mar 19, 2002
Appl. No.:
10/101242

International Classification:
C03B018/14
US Classification:
065/022000, 065/051000, 065/093000, 065/099200, 065/146000
Abstract:
The present invention provides a method of producing patterned and/or textured glass by applying a material onto at least a portion of a glass substrate, e.g., a float glass ribbon, at or above a softening point of the material and/or the glass substrate. The material is configured to affect the surface of the glass substrate to scatter light rays. An apparatus of the invention for forming patterned glass in a float glass process includes an applicator extensible into and out of a float bath chamber above a molten metal bath. A glass article of the invention includes a first surface and a second surface spaced from the first surface. The second surface includes a patterned portion configured to scatter light rays.
