Conservators at Liverpool’s world-renowned Conservation Centre (part of National Museums Liverpool) have been using a Lynton laser cleaning system in a successful conservation treatment of a Roman mosaic. The 4th-century AD mosaic discovered in Medbourne, Leicestershire, in the18th-century was thought to have been completely lost until recently when a piece of the mosaic was discovered in the storage area of the museum. The laser was used to gently clean dirt from the surfaces and vertical edges of the fragile white (limestone), red (terracotta) and blue (whinstone) tesserae, without disturbing the surrounding mortar.
