Theory, statistical modeling, and experiment all indicate that soda-lime silicate compositions with improved properties required for more efficient chemical strengthening can be developed. Currently, more than 90 % of chemically strengthened glass are alkali alumino-silicates having high melting and processing temperatures that are not generally suitable for cost sensitive products, such as glass containers, consumer glassware, and float glass. SLS based compositions are rarely strengthened due to low K-Na interdiffusion coefficients. Exchange times required to achieve acceptable compressive stresses and case depths of 40 - 50 µm are on the order of 24. SLS glasses and post-forming treatments that permit a minimum 50% reduction in the processing times for 40-50 µm exchange depths, while maintaining efficient melting, reliable forming and acceptable performance, are required. The present paper considers how statistical modeling, experimental results and theoretical considerations indicate possible paths forward for commercial production of such glasses.
