The author investigated the rapid method of measuring slag basicity and decided the method with a reflex microscope in which the slag basicity could be measured in 5∿15 minutes. But this method was not yet applicable in some points to an electric furnace melting practice. Therefore, the author continued to investigate the method which was more applicable to the actual operation than the above-mentioned one. The results obtained were as follows : - The slag basicity could be measured with conditions of surface, fracture of slag pancake and colour of slag powder. The relations between lustre and crease of surface, porosity of fracture, colour of powder, basicity (CaO/SiO_2) and ΣFeO were decided. As the result of these experiments, basicity and ΣFeO could be measured in only 3 minutes after the slag pancake was taken. But this method was a little inferior to the method by reflex microscope in accuracy.
