The Optical Properties of some Lime-Soda Glasses

JSGT_1920_V04_T111_T115 (5 pages)

The measurements recorded in this paper refer to the series of lime–soda glasses, the composition and various properties of which have already been described in previous papers. It is not imagined that the series of glasses investigated, namely, those of the trisilicate type between 6SiO₂.2Na₂O and 6SiO₂.Na₂O.CaO is sufficiently wide to satisfy the designer of optical instruments, but the results at least serve to demonstrate the influence of lime, relative to soda, on some of the fundamental optical constants.
