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.
Overview: stone cleaning, for better or worse? - an overview, Ingval Maxwell. Part 1 The broad issues: a brief history of grime - accumulation and removal of soot deposits on buildings since the 17th century, Peter Brimblecombe; towards an aesthetic theory of building soiling, Chris Andrew; stone cleaning - a professional view, James Simpson; sources of building soiling and a review of the stone cleaning industry 1991, Trudie Mansfield. Part 2 Case studies and experimental investigation: to clean or not to clean buildings within Edinburgh, Alastair Milligan; Scott Monument - a brief study report, Hurd Rolland Partnership, John Dixon; the cleaning of the Palace of Westminster, Chris Tucker; a conservator's approach to architectural stonework, Jane Porter; the composition and weathering of sandstone with relation to cleaning, Brian Bluck; abrasive cleaning of sandstone buildings and monuments and experimental investigation, Maureen Young and Dennis Urquhart; research on cleaning methods applied to historical stone monuments, Martin Werner and Claudia Neuwald; experience with cleaning and consolidating stone facades in Hungary, Mihaly Zador. Part 3 The cleaning of carbonate stone: stone cleaning by the inversion of gypsum back into calcium carbonate, Theodor Skoulikidis and Paraskevi Papakonstantinou; removal of sulphated-crust from marble using sulphate reducing bacteria, K. lal Gauri et al; geochemical considerations in the cleaning of carbonate stone, Richard Livingstone. Part 4 Urban conservation issues: "acid rain" - the cleaning and conservation of stonework in Bath, David McLaughlin; conservation and planning considerations in stone cleaning, Chris Andrew and Emma Crawford; stone cleaning in urban conservation, Dennis Rodwell; building cleaning - process or procedure, an industry view, Craig Liddle. Part 5 Chemical and microbiological studies: chemical cleaning of sandstone - comparative laboratory studies, John MacDonald et al; effects of particulate air pollutants on materials - investigation of surface crust formation, Brian Whalley et al; the impact of stone cleaning on micro-organisms and microbially influenced corrosion, Markus Wilimzig et al; microbial interactions with building stones, with special reference to various cleaning, conservation and restoration techniques, Wolfgang Krunbein et al; microbiological damage to building stone - analysis and intervention, Robert Palmer Jr. Part 6 Stone decay, weathering and future prospects.
