Repaired Rocks 2014-17


Return to Sender, Berwick Museum and Art Gallery 2014




Repaired Rocks are limestone rocks that were once part of the solid geological landmass of Lindisfarne. Dispersed and separated from their source through quarrying and processes of erosion these fragments are fractured, cracked, broken and split. The rocks have gone through a process of material reparation using quicklime produced from limestone collected from an abandoned quarry on the island.

Heating limestone above 800Âșc causes thermal decomposition into quicklime and carbon dioxide. The lime is then used to create the lime mortar used in the sculptures, this mortar sets by reabsorbing carbon dioxide from the atmosphere and transforming once again into limestone.
