The density and refractive index of soda-lime-silica glasses are greater than those of vitreous silica due to the filling of interstices in the network by the sodium and calcium ions. As a result, the density increases to =2.5 gcm, while the refractive index increases to = 1.51. The small variations in these properties with typical variations in glass composition for commercial soda-lime-silica glasses is rarely of pragmatic importance.
