The increasing production of fly ashes from carbon combustion in thermal power plants has compounded environmental problems worldwide. As one of promising solution the vitrification of fly ashes could be considered. For potential application chemical durability of material should be known. Dissolution of coal fly ash glass grain samples was studied. The glass was obtained by melting a mixture of coal fly ash, Na2CO3 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 = 950C for t =2h. It was shown that dissolution rate of glass in distillated water and NaOH is negligible, while in HCl solution was shown significant mass loss.
