In this work we used two glass stability (GS) parameters, which best correlate with the glass-forming ability (GFA), in an extensive study for analyzing the influence of alkali and alkaline earth modifiers and five glass-formers, in the crystallization resistance of binary oxide glasses. For the good glass formers silica, boria and germania, the addition of small amounts of modifiers rapidly reduces the GS, whereas for the conditional glass formers telluria and alumina, it initially increases the GS. Lower liquidus temperatures are associated with a better GS, and above 50 molar percent of modifier oxide, the liquidus temperature seems to be the main factor controlling GS (except for telluria). Lithium containing glasses show the lowest GS between the alkali systems, while the alkaline earth modifiers show the same effect on the GS. The TeO2 is the only exception, for which the barium tellurites show better GS. The pure oxides rank in the following order of GS: B2O3>SiO2>GeO2>TeO2>Al2O3. (AU)
