This text brings together papers by scientists, conservators and building surveyors active in stone decay and conservation research with in the United Kingdom. It addresses issues of weathering, mechanisms, and rates, the effects of urban pollution, cleaning methods, and the role of the conservator within research. The concepts regarding the value of stone heritage are also discussed as an important aspect towards retaining our diverse building heritage.
