Abstract: A laminated glass article having a glass core and at least one glass cladding fused to the glass core, the cladding having a porous region at an outer surface thereof. The laminated glass article has a transmittance across an entire spectrum from 875 nm to about 2000 nm that is greater than or equal to 97%, and that has a reflectance across an entire spectrum from 875 nm to 2000 nm that is less than or equal to 3.0%. A method for forming a laminated glass article includes obtaining a laminated glass article have a glass core and a cladding, and heating the laminated glass article to form a phase-separated cladding having an interconnected matrix with discrete dispersed regions. The phase-separated cladding layer is etched to remove the discrete dispersed regions, thereby forming a porous region at a surface of the phase-separated cladding.

Abstract: A method of forming a glass laminate includes providing a substrate having a core layer and at least one cladding layer; heat treating the substrate at a temperature such that the at least one cladding layer is phase-separated after the heat treating; and etch treating the substrate for at least 10 sec. A phase-separated glass laminate includes a substrate having a core layer and at least one phase-separated cladding layer, such that the glass laminate has a % transmission of at least 96%, and the at least one cladding layer comprises a grain size in a range of 10 nm to 1 μm, or a graded glass index of greater than 5 nm.
