    摘要: A method for making a float glass convertible into a glass ceramic, by which a largely crystal fault-free glass can be produced. In this method the glass is cooled from a temperature (TKGmax), at which a crystal growth rate is at a maximum value (KGmax), to another temperature (TUEG), at which practically no more crystal growth occurs, with a cooling rate, KR, in ° C. min−1 according to: KR UEG KG max ≥ Δ ⁢   ⁢ T UEG KG max 100 · KG max , wherein ΔT=TKGmax−TUEG, and KGmax=maximum crystal growth rate in μm min−1. The float glass has a thickness below an equilibrium thickness, a net width of at least 1 m and has no more than 50 crystals with a size of more than 50 μm, especially no crystals with a size of more than 10 μm, per kilogram of glass within the net width.

      摘要: This invention relates to a flat float glass that can be prestressed or transformed into a glass ceramic with high quartz mixed crystals or keatite mixed crystals. To eliminate undesirable surface defects during floating and to achieve superior characteristics of the glass or of he glass ceramic, in particular with regard to a low coefficient of thermal expansion and high light transmittance, the glass has a concentration of less than 300 ppb Pt, less than 30 ppb Rh, less than 1.5 wt. % ZnO and less than 1 wt. % SnO2, and is refined during melting without the use of the conventional fining agents arsenic oxide and/or antimony oxide.
