A rapid and accurate determination of the ratio of lime and silica in basic slags was carried out by the spectrum method. In the present method, the powdered sample is placed in a concave of copper electrode without using any adhesive agent, and the emission is made against the same typed second electrode without any preliminary discharge. And the dry plate is treated with methanol after washing to shorten the analytical time. By this method it is possible to determine 2-4 of the ratio of lime and silica in basic slags within about one hour and with errors less than 10%.
