Helium permeability has been measured for a wide range of soda-lime-silica glasses. The results have been used to define the interconnectivity and miscibility limits for this glass-forming system. Results of heat-treatment studies have also been used to determine the interconnectivity boundary temperature for the 2Na/sub 2/OxCaOxXSiO/sub 2/ compositional line. It has also been shown that the replacement of Na/sub 2/O by CaO substantially reduces the mobility of helium in those glasses lying outside the immiscible region.
