In our work we melt the glass batches at in the temperature range from 800���900��C and soaked for 90 min to achieve homogeneity of the glass. We study the pH of the leachate and it was ranging from 6.18 up to 7.45 under different time. We performed the Leaching behavior the sample glasses in a apparatus called Soxhlet with a maximum time period of 200 h with distilled water. Weight losses of the glasses were measured electronic balance with time interval. Residual activities were followed by ���Radiotracer technique��� with cumulative time period for leaching. Leaching rate is calculated by measuring the surface area of the leached glass samples. The findings are 4.14��10���4 and 8.26��10���3 (in g.m���2.h���1) respectively at 90��C. The result are explained with ionic potential value (the ionic charge/ionic radii) of modifier doped in glass structure. Leaching studies are important because waste glasses have to be kept under ground for a very long time period.
