Abstract
A colored glass article may include 50-80 mol % SiO; 7-20 mol % AlO; 1-35 mol % RO, wherein RO comprises at least one of LiO, NaO, and KO; 1×10-10 mol % of a colorant, wherein the colorant comprises at least one of CrO, Au, Ag, CuO, NiO, CoO, TiO, CeO; and 12-24 mol % of AlO+MgO+CaO+ZnO. The colored glass article may have a transmittance color coordinate in the CIELAB color space with an L* value of 55 to 96.5. The colored glass article may have a compressive stress profile with a depth of compression ≥0.15t, a thickness t from 0.4 mm-5 mm, a compressive stress ≥200 MPa, and a central tension ≥60 MPa. The colored glass article may have a dielectric constant from 5.6 to 6.4 over the frequency range from 10 GHz to 60 GHz.
