    Abstract: A method of marking a glass-ceramic article includes the steps of: illuminating a glass-ceramic article with a beam from a laser, the glass-ceramic article having a thickness, T; and forming a mark in the glass-ceramic article while translating at least one of the glass-ceramic article or laser. The mark has a Contrast Ratio greater than 10. The step of forming a mark includes focusing the beam from the laser within the thickness, T, of the glass-ceramic article. The focusing of the beam results in alteration of a chemical property or a physical property of the glass-ceramic article. The mark produced by the beam from the laser extends through at least 50% of the thickness, T, of the glass-ceramic article. The glass-ceramic article may have a global temperature less than 100° C. during the marking process and does not fracture as the mark is formed.

    Abstract: An article includes SiO2 from about 40 mol % to about 80 mol %, Al2O3 from about 1 mol % to about 20 mol %, B2O3 from about 3 mol % to about 50 mol %, WO3 plus MoO3 from about 1 mol % to about 18 mol % and at least one of: (i) Au from about 0.001 mol % to about 0.5 mol %, (ii) Ag from about 0.025 mol % to about 1.5 mol %, and (iii) Cu from about 0.03 mol % to about 1 mol %, and R2O from about 0 mol % to about 15 mol %. The R2O is one or more of Li2O, Na2O, K2O, Rb2O and Cs2O. R2O minus Al2O3 ranges from about −12 mol % to about 3.8 mol %.

    Abstract: A colored glass article may include 50-80 mol% SiO2; 7-20 mol% Al2O3; 1-35 mol% R2O, wherein R2O comprises at least one of Li2O, Na2O, and K2O; 1 × 10-6-10 mol% of a colorant, wherein the colorant comprises at least one of Cr2O3, Au, Ag, CuO, NiO, Co3O4, TiO2, CeO2; and 12-24 mol% of Al2O3 + 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 5.6to 6.4 over the frequency range from 10 GHz to 60 GHz.
