Also the effect of MnO is not clear-cut since the 18 slags of 93 mass% MnO-content could easily be reduced. The texture of the slags was classified into group 1 : fayalite of changing quantity, further A, B and C-type vitreous silicates and more or less FeO. The slags of types 1,2,6, 12,16 contained less fayalite, but they contained charcoal and ore remainders, too; in the slags marked 2, 9, 12, 16 were found greater MnO contents. A connection between the external characteristics and the test results could not be ascertained. References 1. A.
