Coal fly ash represents huge ecological problem and its reutilization should be considered. Vitrification of coal fly ash could be one of the solutions. The glass was obtained by melting a mixture of coal fly ash, glass cullet and CaCO3 at T = 1500 oC and quenching the melt in air. The chemical durability of the glass was determined by dissolution test in distilled water, HCl and NaOH at T = 95 0C for t = 2 h. It was shown that dissolution rate of glass in distillated water and NaOH is negligible, while in HCl solution was shown significant mass loss.
