Historic Portuguese ceramic tiles on walls at the Museum of Sacred Art in Salvador, Bahia, Brazil. Damage to the tiles is the result of salt coming up from groundwater through the building structure and out between seams in the tiles. Loss to the tile glazing is caused by salt crystallization pressures. At the Museum of Sacred Art, environmental management strategies were developed that integrated the conservation needs of both the historic structure and the collection. Photo: James Druzik.
