Note on the Solubility of Sodium Chloride in a Soda-Lime-Silica Glass
JSGT 1939 V23 T265 -T267
By melting increasing and excessive amounts of sodium chloride in the batches, it was found that a soda-lime-silica glass of initial composition SiO2 75, CaO 9.2, Na2O 15.8% dissolved sodium chloride at 1400° in amount equivalent to 1.42% of Cl, or 2.34% NaCl.
