The effects of both fining agents and TiO 2 concentration on the solarizability of a borosilicate glass proposed for solar energy applications have been determined. Optical and ESR measurements indicate that chlorine‐fined glasses are much less susceptible to solarization than are arsenic‐fined glasses. Titanium dioxide acts as a solarization suppressant with either fining agent. The observed increase in optical absorption in the visible region is in marked contrast with the recent report of a solar‐induced decrease in optical absorption in the infrared range for soda‐lime silicate glasses.
