• Resumen

  • The chemical composition and morphology of salts present in the San Jerónimo Monastery, lead us to establish two different associations and formation processes: a) massive and pulverulent subefflorescence made up of Mg, Na and K sulphates and also by Na carbonate, produced by percolating water through decayed ashlar; b) crystalline subefflorescences of NaCl originated by capillary rise of ground moisture,. Subefflorescences promote pression under wall painting and other decoratives constituents adjoined to the wall leading to their detachement, in some cases irreversible.
