This study used a combined viscosity approach to determine theoretical fibre drawing points for glasses in the series: xP2O5, 24MgO, 16CaO, (60-x)Na2O (x = 0,45,50,55) and yP2O5, 24MgO, 16CaO, (55-y)Na2O, 5Fe2O3 (y = 40,45,50,55). The points cannot be measured directly since the glasses are only kinetically stable at these points and would crystall
