The altered glass forms a hydrated solid phase bearing about 10 wt% of H 2 O in the form of Si-OH groups and molecular water. No alkali depletion was observed after ageing tests. Structural results from 1 H, 23 Na and 29 Si MAS NMR point out the close proximity of Si-OH, H 2 O and Na + species. This study gives new insight into the mechanisms of the atmospheric alteration, essential to conservation strategies in industry and cultural heritage. %G English %L cea-01510271 %U https://cea.hal.science/cea-01510271 %~ CEA %~ ENSCP %~ CNRS %~ ENSC-PARIS %~ PARISTECH %~ PUBNIMBE %~ INC-CNRS %~ IRAMIS-NIMBE %~ CEA-UPSAY %~ PSL %~ UNIV-PARIS-SACLAY %~ CEA-UPSAY-SACLAY %~ TEST-HALCNRS %~ ENSCP-PSL %~ GS-ENGINEERING %~ IRAMIS %~ GS-CHIMIE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ TEST2-HALCNRS
