  Glass formation is one of the most interesting phenomena in the condensed
matter field. Considerable effort has gone into understanding and predicting
the glass formability. However, the previous prediction requires the glass
first made before the prediction can be performed. Here, we propose a new
prediction formula using liquid properties only. Moreover, we demonstrated that
the similarity between liquid and crystalline structure plays an important role
in determine the glass formability. Previously, only the kinetics of nucleation
and growth processes have been considered.
