This study examines the various processes and the methods of determining urban stone decay. The contributions include coverage of: spatial variability of dissolution on a limestone surface; ageing of consolidated stone; and techniques for making contemporary copies of stone antiquities.

This volume offers valuable insights into the nature of decay processes and the factors that control them. It presents several studies on the impact of pollution on stonework in urban environments. Important methodological contributions cover: the mapping of facades to explain rates of decay associated with conservation actions; the laboratory simulation of corrosion in polluted atmospheres; the quantification of colour change through a study of the artificial ageing of building stone. The effectiveness of stone treatments within the laboratory is also considered.
