Treatments for improvement of the alkali extraction characteristics of the internal surfaces of soda lime glass containers are described. The extent of improvement was determined by an alkali extraction procedure considerably more stringent than the conventional USP chemical resistance procedure. The degree of improvement is described in terms of acid titration value, pH elevation and analysis of the extract solution for Na and Si. In addition, the results of surface analyses of the treated surfaces by an ion micro probe (SIMS) technique are described.
