Annotation
A M$\stackrel{..}{o}$ssbauer study of Na$_2$O-CaO-SiO$_2$ glasses with low (up to 1%) content of iron enriched in the $^{57}$Fe isotope has been conducted. The structural and valence states of the Fe$^{2+}$ and Fe$^{3+}$ ions have been analyzed. A component with a characteristic magneto-relaxation shape observed in the spectra is indicative of the formation of ultrasmall Fe$^{3+}$ oxide clusters in glasses.
