Query: Fragility and molar volumes of non-stoichiometric chalcogenides -- the
  crucial role of melt/glass homogenization   Melt-fragility index (m) and glass molar volumes (Vm) of binary Ge-Se
melts/glasses are found to change reproducibly as they are homogenized.
Variance of Vm decreases as glasses homogenize, and the mean value of Vm
increases to saturate at values characteristic of homogeneous glasses. Variance
in fragility index of melts also decreases as they are homogenized, and the
mean value of m decreases to acquire values characteristic of homogeneous
melts. Broad consequences of these observations on physical behavior of
chalcogenides melts/glasses are commented upon. The intrinsically slow kinetics
of melt homogenization derives from high viscosity of select super-strong melt
compositions in the Intermediate Phase that serve to bottleneck atomic
diffusion at high temperatures.
