      abstract     = {A modified Avramov equation is employed to describe the
                      viscosity of silicate melts in the SiO2-Al2O3-Na2O-K2O
                      system and its subsystems with associate species obtained
                      from thermodynamic description and used as structural units.
                      Two modifications to the Avramov equation are proposed: i) a
                      stronger dependence of viscosity input of each structural
                      unit on its concentration ii) the “fragility” parameter
                      dependent on the melt composition at a given point. The
                      model describes the viscosity reasonably well for most of
                      the experimental data in the wide compositional range and in
                      a temperature range from fully liquid to supercooled melts.
                      Approaches to further improve the model are discussed.},
