Abstract: The conditions for the vaporization of 2 nonconductors from the crater of the C electrode can be graphically expressed by the application of the relation of the integral intensity J of spectral lines of the known sample on the unknown sample. For the theoretical part, Lomakin's (CA 24, 2080) and Scheibe's (S. and Schnettler, CA 25, 2070) equations were used. Several examples with graphs are given. A typical case of fractional distn. is the vaporization of MgO and Al₂O₃ in the ratio 1:1. MgO is vaporized first. The mixt. of Na₂CO₃ and K₂CO₃ in the ratio 1:1 vaporizes equally and gives a straight line graph. The mixt. of Al₂O₃ and SiO₂ with kaolin and Li₂CO₃ also gives a straight line graph.
