  This report shows the universal previtreous behavior of the pressure related
apparent fragility, i.e. the steepness index Basing on this finding, the
3-parameter relation for portraying the previtreous behavior of the primary
(structural) relaxation time is derived. The fair portrayal of experimental
data was shown for glass forming 8*OCB (liquid crystal), EPON 828 (resin) and
diisobutyl phthalate, propylene carbonate (low molecular weight liquids). On
decompressing, the dynamic crossover dynamic domains is clearly detected. All
these recalls the mode-coupling-theory behavior, but for the pressure path. It
is notable, the discussed description offers the fair portrayal of experimental
data even in the extreme pressure range P up to 2.2 GPa.
