    摘要: A glass-ceramic of the lithium aluminosilicate type includes a solid solution of β-spodumene and exhibits, for a thickness of 4 mm; a light transmittance within a range extending from 0.3 to 2%, an optical transmittance for a wavelength of 625 nm of greater than 3.0%, an optical transmittance for a wavelength of 950 nm within a range extending from 50 to 75%, an optical transmittance for a wavelength of 1600 nm of at least 50%, and L*, a*, b* colorimetric coordinates in diffuse reflection for an illuminant D65 and a reference observer at 2° such that 15.0≦L*≦40.0, −3.0≦a*≦3.0 and −10.0≦b*≦3.0. The chemical composition of the glass-ceramic includes the following constituents, varying within the limits by weight defined: SnO2 0.2-0.6%, V2O5 0.015-0.070%, Cr2O30.01-0.04% or Bi2O3 0.05-3.0%, Fe2O3 0.05-

    摘要: A glass-ceramic article is at least partly coated with at least one layer of enamel, including a glass frit. The frit includes, expressed by weight, SiO2, 45-60%; Al2O3, 12-22%; B2O3, 12-22%; Li2O, 0-5%; Na2O, 0-2%; K2O, >2%; CaO, 0-4%; MgO, 0 - 4%; ZnO, 0-4%; BaO, 0-4%; ZrO2, 0-4%; and TiO2, 0-1%. The sum of oxides CaO+MgO+BaO+SrO+ZnO is at most 10%, preferably from 2 to 8%. A process can be used to obtain the article.
