The processes of melting of various types of igneous rocks that make up gabbro-basalt raw materials are considered. The role of the main rock-forming elements in the formation of these melts for the production of mineral fibers and petrurgy products is shown. Particular attention is paid to their influence on the viscosity and crystallization ability of industrial melts, as well as iron - the only element present in two oxidation states Fe (II) and Fe (III), which can participate, respectively, in the isomorphism of Mg and Al. Information on the influence of the ratio of these oxides on the crystallization of mineral fibers of stone casting products is given.
