The disclosure provides textured glass components as well as electronic device cover assemblies and enclosures which include the textured glass components. In some cases, a protruding portion of the glass component includes a textured region provided over a camera assembly of the electronic device. One or more openings may be provided in the textured region. The textured region may be configured to provide a translucent or hazy appearance to the electronic device while providing a desirable “feel” to the electronic device and level of cleanability.

A glass structure includes: a glass substrate that includes a thick portion and a thin portion thinner than the thick portion; and a filler that covers a step surface formed by difference in height between the thick portion and the thin portion. A refractive index difference at a wavelength of 555 nm between the glass substrate and the filler is 0.008 or less in an absolute value. A refractive index difference at a wavelength of 507 nm between the glass substrate and the filler is 0.008 or less in an absolute value.

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.
