Abstract

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: delamination, 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 desalination 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.
