A composition study was made in this work to find a more durable, easily fabricated phosphate glass with a suitable glass transition temperature Tg allowing for moulded optics. Glass samples were characterised for Tg, hardness and chemical durability. Composition of interest involves an introduction of a small amount of tin oxide which was found to increase the chemical durability while keeping the Tg at an acceptable level.
