Fourteen century limestone deterioration: Desalination and restoration criteria
This paper describes conservation-restoration works carried out on the limestone dating 14th century, depicting St. Simeon and Elizabeth of Bosnia. Due to long-term exposure to environment in the museum yard and one inadequate restoration work in the 1950s, the stone showed a wide range of decay forms such as: delami-nation, exfoliation, disintegration, splintering, and powdering. The thickness and the shape of the damaged layers of the stone were variable. Laboratory research has shown a high concentration of soluble salts (chlorides, sulphates and nitrates, dominantly halite and gypsum), which caused accelerated decay of the limestone ; therefore, the conservation- restoration process was focused on different desalina-tion methods. Water baths were chosen for the desalination method, followed by barium hydroxide treatment. Before and after the desalination treatment, stone was consolidated by nano-lime. After the treatment, the stone relief was stabilized and ready for return to stabile museum environment.
