    摘要: A transparent low-colour lithium aluminium silicate (LAS) glass ceramic and the use thereof are described, said glass ceramic having an environmentally friendly composition with high-quartz mixed crystals as the main crystal phase and advantageous production features. The glass ceramic contains the following components (in wt% on the basis of oxide): TiO
    2 1.6 - 2 O
    3 0.005 - 0.15; MgO 0.2 - 1.0; ZnO 1 - 2.5; CaO + SrO 0 - 1.5; BaO 0 - 1.5 with the condition B1: MgO + ZnO > CaO + SrO + BaO. The glass ceramic has a hue c* of less than 5.5, a light transmission Y greater than 81% and has no visually disruptive diffusion.

    摘要: The invention relates to a method for producing bubble-free glasses, in which a glass mixture that is arsenic-free, antimony-free and tin-free with the exception of any unavoidable raw material impurities and at least one sulphate compound as refining agent are used. The glass mixture comprising refining agent is melted in a melting tank (1), melting down taking place and a primary refinement being carried out in a first region (10) of the melting tank (1), an average melting temperature (T
    1 ) being set at T
    1 > 1580 °C and an average melt residence time (t
    1 ) being set at t
    1 > 2 hours in the first region (10). A secondary refinement is carried out in a second region (20) of the melting tank (1), an average melting temperature (T
    2 ) being set at T
    2 > 1660 °C and an average melt residence time (t
    2 ) being set at t
    2 > 1 hour in the second region (20), and the proportion of the (SO
    3 ) resulting from the decomposition of the sulphate compound being reduced to less than 0.002 wt.%, at the latest as the secondary refinement is being carried out. A high-temperature refinement is carried out after the secondary refinement.
