Abstract: A glass-ceramic article is provided that includes a surface passivation layer. The passivation layer is an oxide layer and has a thickness of greater than or equal to 20 nm to less than or equal to 200 nm and a RMS surface roughness of less than or equal to 3 nm. The surface passivation layer may be formed with a liquid phase deposition process. The glass-ceramic article may include an easy to clean layer disposed on the surface passivation layer, and the glass-ceramic article may be chemically strengthened. The glass-ceramic article may be used in a consumer electronic product.

Abstract: A glass article is provided (and methods of making the same) that includes: a glass substrate comprising a thickness and a first primary surface; and a porosity-graded layer that extends from the first primary surface of the substrate to a first depth within the substrate. The first depth is from about 250 nm to about 3000 nm. The porosity-graded layer comprises a plurality of pores having an average pore size from about 5 nm to 100 nm. The article comprises a single-side average reflectance of less than 9% at an incident angle of 60 degrees across a spectrum from 350 nm to 2000 nm. Further, the porosity-graded layer comprises a surface porosity at the first primary surface and a bulk porosity at the first depth, the surface porosity greater than the bulk porosity.
