The surface morphology of double-phase magnetic alkali borosilicate glasses of four types obtained by induction melting is studied by the methods of atomic-force and scanning electron microscopy. The distribution of elements over the surface and the elemental composition of the glasses are determined. It is shown that a dendritic system of interrelated channels required for formation of porous matrixes with controlled mean pore diameter may be obtained in these objects depending on the heat treatment mode.
