In part I of Conservation of Building and Decorative Stone the introduction to the complexities and background history of stone conservation is followed by the most comprehensive description yet produced of the building and decorative stones used in the British Isles. Whilst this section makes the book of particular importance to British practitioners, giving reference buildings for all stones, the detailed information on the origins and characteristics of rocks is of international interest and relevance. The nature of building and decorative stones in the context of weathering and decay is also explored in such a way that practitioners will be guided towards successful diagnosis and analysis of deterioration problems. A proper understanding of the nature and decay mechanisms of stones is essential for the correct specification and execution of conservation work.<BR>In part 2 practitioners involved in stone conservation describe ways in which major structural masonry problems, secondary building problems and different stone surface conditions may be treated. A variety of building types and environments has been used to ensure that the broad scope of common problems is covered, from the ruined site to the standing roofed building and from the museum 'controlled' site to the sculptured church monument. This second part of the volume will be of practical value to art historians, archaeologists, architects, surveyors and engineers, masonry contractors and sculpture conservators in solving problems and in learning to use each other's skills and experience.
