  In the last few decades, theoretical and experimental studies of
glass-forming liquids have revealed presence of universal regularities in the
viscosity-temperature data. In the present work, we propose a viscosity model
for scaling description of experimental viscosity data. A feature of this model
is presence of only two adjustable parameters and high accuracy of experimental
data approximation by this model for a wide temperature range. The basis of the
scaling description is an original temperature scale. Within this scaling
description we obtain the transformed Angell plot, in which the area separating
"fragile" and "strong" glass-formers emerges. The proposed scaling procedure
make it possible to reconsider belonging some liquids to the type of "fragile"
glass-formers. The obtained results form basis for development of a generalized
scaling description of crystallization kinetics in supercooled liquids and
glasses.
