Much research has recently been undertaken into the cleaning and conservation of stone buildings, particularly those constructed of sandstone, and the debate concerning the best methods continues. This book brings together contributions from a wide range of specialisms, and offers new perspectives on the important issues surrounding this subject.
Much research has recently been undertaken into the cleaning and conservation of stone buildings, particularly those constructed of sandstone, and the debate concerning the best methods continues. This book brings together contributions from a wide range of specialisms, and offers new perspectives on the important issues surrounding this subject. The topics covered encompass not only theoretical and philosophical concerns, but also problems of weathering and microbiological damage. The practical case studies help to highlight the problems, and the laboratory experiments offer vital information that should provide a valuable contribution to the existing body of knowledge in this field. This book should be a reference for all building practitioners and academics who are interested, and actively involved, in conserving stone buildings and monuments.
