(1) Fayalite, Tephroite, and artificial slag were electrolysed in molten states by D. C. 12 volts. (2) Electrolytic effects were analysed by improved potentiometry, (3) Ionic mobility of F^<++> is relatively large and this is suggested by the fact that the molten slags containing FeO are high electric conductivity. (4) The electric conductivities of MnO-SiO_2 system were measured at several temperatures and chemical compositions. It was revealed that the specific electric conductivity was proportional to reciprocal of absolute temperature. Moreover the energy of activation was calculated that was so much useful in considering the structure of slags. (5) The difference between MnO-CaO-SiO_2 and FeO-CaO-SiO_2 in electric conductivity was shown. This is attributed to the difference between the behabiours of MnO and FeO. (6) The specific gravity of CaO-SiO_2-Al_2O_3 system was measured.
