A comparison is made between the attack by NaOH and that by sodium silicate solutions on a borosilicate glass, a lime glass, and a lead glass. Below roughly 0.5 Na2O normality the rate of attack by NaOH is greater, but at higher normalities this is more than doubled in some instances by that of silicate solutions of equivalent Na2O normality. The rate of attack by sodium silicates generally reaches a maximum as a function of the SiO2:Na2O ratio and decreases to low rates for high ratios. A similar behavior is observed for potassium silicate solutions, the maxima occurring at about the same silica‐to‐alkali ratios.
