Textured glass articles and methods of making the same
A glass article is provided that includes: a glass substrate comprising a thickness and a primary surface; and a textured region defined by the primary surface. The textured region comprises a plurality of sub-surface hillocks, each hillock having a top surface and a base, the base located below the primary surface of the substrate. The plurality of hillocks comprises an average lateral feature size from 0.1 μm to 3 μm and an average height from 5 nm to 200 nm. Further, the primary surface of the substrate is substantially planar.

GLASS FOR AUTONOMOUS CAR
A trim element for a motor vehicle that includes at least one glass sheet having an absorption coefficient lower than 5 m.sup.−1 in the wavelength range from 1051 nm to 1650 nm and having an external and an internal faces. An infrared-based remote sensing device in the wavelength range from 1051 nm to 1650 nm is placed behind the internal face of the glass sheet.
GLASS FOR AUTONOMOUS CAR
A trim element for a motor vehicle that includes at least one glass sheet having an absorption coefficient comprised between 5 m.sup.−1 and 15 m.sup.−1 in the wavelength range from 750 to 1650 nm and having an external and an internal faces. An infrared-based remote sensing device in the wavelength range from 750 to 1650 nm is placed behind the internal face of the glass sheet.
Glass sheet with a high luminous transmittance and with warm-toned to neutral colored edges
The invention relates to a glass sheet having a luminous transmission LTD4≥87% and having a composition free of antimony and arsenic, comprising total iron (expressed in the form of Fe.sub.2O.sub.3) from 0.002-0.04% and erbium (expressed in the form of Er.sub.2O.sub.3) from 0.003-0.1%. The glass sheet composition further having a redox ratio ≤32% and satisfying the formula 1.3*Fe.sub.2O.sub.3≤Er.sub.2O.sub.3−21.87*Cr.sub.2O.sub.3−53.12*Co≤2.6*Fe.sub.2O.sub.3. Such a glass sheet has a high luminous transmittance and has warm-toned to neutral colored edges and is particularly suitable due to its aesthetics as building glass or interior glass, as well as in furniture applications, as automotive glass, or as cover glass in electronic devices/displays.
Feed Material for Producing Flint Glass using Submerged Combustion Melting
A vitrifiable feed material for producing flint glass by way of a process that uses submerged combustion melting includes a base glass portion, an oxidizing agent, and a decolorant. The base glass portion includes an SiO.sub.2 contributor, an Na.sub.2O contributor, and a CaO contributor to provide SiO.sub.2, Na.sub.2O, and CaO, respectively, to a glass melt when melted therein. The oxidizing agent may be a sulfate compound in an amount ranging from 0.20 wt % to 0.50 wt % as expressed as SO.sub.3 based on the total weight of the vitrifiable feed material, and the decolorant may be selenium in an amount ranging from 0.008 wt % to 0.016 wt % or manganese oxide in an amount ranging from 0.1 wt % to 0.2 wt % based on the total weight of the vitrifiable feed material.
