Starting from a multicomponent lead phosphate glass composition given in the literature, a glass was developed suitable for the protective overclad of heavy-metal fluoride glass fibres. Besides a low glass transition temperature 18.10-6K-1, the phosphate glass material developed had a water resistance at 60 degC for 10h comparable to that of commercial container glass.
