  While lot of measurements describe the relaxation dynamics of the liquid
state, experimental data of the glass dynamics at high temperatures are much
scarcer. We use ultrafast scanning calorimetry to expand the timescales of the
glass to much shorter values than previously achieved. Our data show that the
relaxation time of glasses follows a super-Arrhenius behaviour in the
high-temperature regime above the conventional devitrification temperature
heating at 10 K/min. The liquid and glass states can be described by a common
VFT-like expression that solely depends on temperature and limiting fictive
temperature. We apply this common description to nearly-isotropic glasses of
indomethacin, toluene and to recent data on metallic glasses. We also show that
the dynamics of indomethacin glasses obey density scaling laws originally
derived for the liquid. This work provides a strong connection between the
dynamics of the equilibrium supercooled liquid and non-equilibrium glassy
states.
