A biocompatible glass which can be melted using infra- red radiation is described which contains, based on oxide, 65-68% by weight of SiO2, 0 - 3% by weight of Li2O, 12 - 14% by weight of Na2O, 2.5 - 4% by weight of K2O, 15 - 17% by weight of .SIGMA. alkali metal oxides, 2 - 3% by weight of MgO, 4.2 - 5.5% by weight of CaO, 0 - 2% by weight of BaO, 3 - 4% by weight of Al2O3, 0 - 1% by weight of B2O3 and 2.7 - 4.1% of FeO. The glass, due to its infra-red meltability and its physiological accep- tability, is suitable for the encapsulation of sensitive materials, such as transponders or minitransmitters, which are implanted in a living body, or as ampoule glass for melt- encapsulation of sensitive substances.
