Glasses were melted in three systems viz., borosilicate, phosphate and pure silicate system. In the present work we could melt the glass at much lower temperature (800-950oC) with a soaking period of 30 min-1 hr which were earlier reported to be melted not below 1000o C. The effect of different modifier ions like Pb²⁺, Ba²⁺, Na+, Fe³⁺, Al³⁺, Y³⁺, Ca²⁺, Ce⁴⁺ and Sr²⁺ on melting temperature and time of melting in each system has been found to be evident. The pH determination in the range 6.43 to 8.18 of the leachate solution at ambient temperature under varying time intervals shows interesting and regular variations. The findings have been corroborated in terms of ionic size, ionic radii and hence ionic potential of the modifier ions.
