These data are from the literature and for the following glasses: 44Na2O∙56SiO2 (N44S56)8,16, Li2O∙2SiO2 (LS2)8,11, BaO∙2SiO2 (BS2)10, 5BaO∙8SiO2 (B5S8)10, and xNa2O∙(50-x)CaO∙50SiO2 (NCS) where the x-values are 33.38,15, 24.47,13, 22.47,13, 21.37,13, 19.27,13, and 16.78,12,13,14, respectively. The solid lines serve as guides to the eye. (Reproduced from refs. 7,8,10 with permission from Elsevier.)
