      abstract     = {The viscosity model recently developed for the fully liquid
                      system SiO2–Al2O3–CaO–MgO–Na2O–K2O is further
                      extended to describe the viscosity of the iron oxide
                      containing low order systems in the Newtonian range. The
                      different structural roles of Fe2 + and Fe3 + to the
                      viscosity are captured by the associate species. Using the
                      monomeric associate species in combination with some
                      specific larger structrual units, the model is capable of
                      describing the viscosity of the melts FeO, FeO–SiO2,
                      FeO–Al2O3, Fe2O3–CaO, Fe2O3–MgO, Fe2O3–Na2O, and
                      Fe2O3–K2O over the whole range of compositions as well as
                      a wide range of temperatures and oxygen partial pressures
                      using only one set of model parameters. A new mechanism is
                      proposed to describe the local viscosity maximum around the
                      fayalite composition in the FeO–SiO2 melt. The model shows
                      that the presence of the local viscosity maximum is
                      dependent on the temperature and oxygen partial pressure.
                      Moreover, the viscosity maximum caused by Al3 +- or Fe3
                      +-induced charge compensation is presented and a good
                      agreement between the calculated viscosities and
                      experimental data is demonstrated.},
