In order to make a quantitative evaluation of stress-enhanced corrosion on glass surface in aqueous solutions, an indentation method was adopted. Using this technique, the stress corrosion limit, K_<SCC> was measured in three different glasses, a soda-lime silicate glass and two kinds of alumino-silicate glasses. Influence of a surface active agent on the stress corrosion limit of soda-lime silicate glass was also estimated using soda kaplinate acid solution. The present results can be summarized as follows : (1)The indentation method can be generally used provided that a median/radial crack can be introduced on the glass surface, and it enables to distinguish subtle differences in the extent of the corrosion process. (2)Accurate K_<SCC> data can be obtained within a 3% standard deviation. (3)By the indentation method the K_<SCC> can be estimated in small specimens or at localized parts.
