| Zusammenfassung: | To provide a high-refractive thin glass.SOLUTION: The thin glass has a refraction index of at least 1.68 and an average thickness d of less than 2 mm. The thin glass has a liquidus viscosity of less than 103 dPas and a refraction index of less than a theoretical refraction index by at least 0.001. The thin glass has further at least one surface subjected to flame polishing having a roughness Ra of a maximum of 20 nm.SELECTED DRAWING: None
