A short review of works devoted to studying the effect of hydrogen-containing fragments of the structure (mainly H₂O and OH⁻-groups) on the physicochemical (mainly electrical) properties of oxide glass has been presented. It was noted that the conduction of alkali-free oxide glass is due to the migration of protons. When introducing alkali metal oxides in their composition in the region of low Me₂O concentrations, the electric current transport is due to the combined migration of protons and alkali metal ions; the conduction due to the migration of exclusively alkali ions is observed at concentrations of alkali metal ion oxides higher than 20 mol %. It was noted that in oxide glass containing ions of alkaline earth metals the conduction is also due to the migration of impurity protons. No participation of ions of alkaline earth metals in the electricity transport was observed.
