Los 20 artículos y 19 resúmenes extendidos presentados en la conferencia se incluyen en esta publicación, agrupados en cuatro categorías: ética, estética, formación y documentación; medios tradicionales: Tempera de huevo y aceite; Pinturas modernas; y Sistemas de limpieza. Dentro de cada categoría, los artículos y los resúmenes están agrupados por el tema específico que tratan. Todos los artículos y resúmenes incluidos en esta publicación han sido revisados. El objetivo de La conferencia consistió en proporcionar un foro de intercambio de conocimientos y producir una publicación que reúna las últimas investigaciones. En los diversos estudios se abordan los problemas que afectan a las pinturas. Estos van desde la suciedad normal hasta la eliminación de barnices envejecidos, desde el efecto de los disolventes sobre las pinturas hasta los cambios posteriores en su comportamiento mecánico. La limpieza de pinturas sin barnizar es uno de los temas más críticos que se discutió. Finalmente, diferentes técnicas de limpieza, tales como geles, jabones, enzimas, líquidos iónicos y espumas, así como varios métodos secos y láseres, se analizan en diversos documentos y resúmenes extendidos.

Before the 1970s, most information concerning the conservation and restoration of paintings, wood, and archaeological artefacts were focused on the history of the artefacts, previous attempts of conservation, and the future use of these artefacts. The technical methods of how the restoration and conservation were made were dealt with only very briefly. Today, sophisticated methods of scientific analysis such as DNA are common place, and this encourages conservators and scientists to work together to work out the development of new methods for analysis and conservation of artefacts. This book focuses on the chemicals used for conservation and restoration of various artefacts in artwork and archaeology, as well as special applications of these materials. Also the methods used, both methods for cleaning, conservation and restoration, as well as methods for the analysis of the state of the respective artefacts. Topics include oil paintings, paper conservation, textiles and dyes for them, archaeological wood, fossils, stones, metals and metallic coins, and glasses, including church windows.

This volume represents 27 peer-reviewed papers presented at the ICOP 2013 symposium which will help conservators and curators recognise problems and interpret visual changes on paintings, which in turn give a more solid basis for decisions on the treatment of these paintings. The subject matter ranges from developments of paint technology, working methods of individual artists, through characterisation of paints and paint surfaces, paint degradation vs. long time stability, to observations of issues in collections, cleaning and other treatment issues as well as new conservation approaches.

This volume explains four different methods for examining paint surfaces. It adopts several examination tools to compare untreated and treated surfaces of oil and acrylic paints, such as scanning electron microscopy (SEM), computer-aided laser profilometry, environmental scanning electron microscopy (ESEM) and 3D-measurement technology. Samples of historic oil paints, contemporary oil paints, and modern acrylic paints, are examined within, using subjective and objective measurements, to reveal ideal surface cleaning systems and methods for painting surfaces. The book presents tests of several surface active materials on oil paints and acrylic paint surfaces, including latex sponges and demineralized water, saliva, cellulose ethers, anionic and nonionic detergents, and microporous sponges.
