International Classification:

C03C 15/00

Abstract:

Glass-based substrates are described herein that may be processed by methods including applying a cover article onto a glass-based substrate, submerging the glass-based substrate in an etchant, and maintaining the submersion of the glass-based substrate in the etchant. The glass-based substrate may include a covered surface portion and an exposed surface portion. At least a portion of the covered surface portion may be in direct contact with the cover article. The covered surface portion may not be in contact with the etchant and the exposed surface portion may be in direct contact with the etchant. The etchant may contact the exposed surface portion and the cover article fora time sufficient to etch the exposed surface portion. The cover article may provide a barrier between the etchant and the covered surface portion for the entirety of the submerging.

H05K 5/00

Abstract:

A method is described herein of making a textured glass article where the method includes: providing a glass substrate having an initial primary surface and an opposing primary surface; disposing a protective coating on at least one of the initial primary surface or the opposing primary surface; and etching the glass substrate with a hydrofluoric acid-free etchant having a pH of about 7 or less to form a leached layer in the glass substrate.
