  Glass forming ability (GFA) is a property of utmost importance in glass
science and technology. In this paper, we used a statistical
methodology---involving bootstrap sampling and the Wilcoxon test---to find out
which glass stability parameters can better predict the glass forming ability.
We collected or measured the necessary data for twelve stoichiometric oxide
glasses that underwent predominant heterogeneous nucleation (the most common
case). We found that some GS parameters could predict the GFA of these oxide
glasses quite well, whereas others perform poorly. Parameter $K_w$ was the top
ranked, closely followed by the $K_H$, $\gamma$, $H^{'}$, $\Delta T_{rg}$, and
$K_{cr}$. Our results corroborate previous reports carried out using a smaller
number of glasses, much less GS parameters, and less rigorous statistics. We
also found that using $T_c$ instead of $T_x$ improved the predictive power of
these parameters. Finally, the Jezica, the only parameter considered here that
predicts the GFA without requiring the production of a glass piece (i.e.,
without relying on any crystallization information), ranked reasonably well in
our analysis.
