This manual offers a detailed introduction to computer graphics for restorers, and places special emphasis on electronic survey techniques. Guidelines are given for the production of digital photographic material and complex designs, the inclusion of the latter in the final report, and finally the printing process. Three of the currently most popular computer graphics programs are demonstrated, both for the Windows and a Macintosh environment. All examples are drawn from practical experiences in restoration training.

This book was created from the growing need among restorers and art historians to understand the actual potential of scientific disciplines in the study of polychrome works of art. In a language that is clear and accessible, but still scientifically rigorous, the authors give an overview of the relevant analytical processes and techniques used in the study of works of art and in restoration work. Without wanting to raise false expectations as to how restoration can benefit from science, the authors point out the costs and the real possibilities of the methodologies described, at the same time emphasising the importance of analysis for the preservation of the artistic heritage.

Lorenzo Appolonia works for the Ministry for Monuments and Artistic Treasures (Valle D'Aosta branch); he also coordinates the GL3-Chimici (UNI-NORMAL Beni Culturali) working group. He is the author of many publications on art conservation.
Stefano Volpin is a restorer-chemist with a special interest in the conservation of paintings and has published a number of articles on the subject. He teaches and collaborates with various laboratories in the public and private sector in the field of analysis of polychrome works. He is also a member of the GL3-Chimici (UNI-NORMAL Beni Culturali) working group.

This volume is addressed to all those who work in the field of restoration, and in particular to those who often handle dangerously toxic substances. A knowledge of the composition of the materials used in restoration, of the physical and chemical interaction between varnishes and solvents, and a knowledge of their toxicity is necessary for those who come into contact with these substances, not only for health and safety reasons, but also as a matter of professional competence.

Rita Marchi Meneguzzi is a physician specialising in respiratory tract diseases.
Franca Ottogalli Perrino is a physician specialising in occupational medicine.

Enzymes are biological catalysts that accelerate chemical reactions on the macromolecular substrate, and can be effectively used in the field of conservation and restoration, especially for the cleaning of paintings and other objects. In many cases, the enzymes' selective action and their water-based medium are less potentially hazardous both for the health of the handler and for the integrity of the object, especially in comparison with less selective methods such as organic solvents and alkaline substances.
These techniques, have matured over the years, now becoming an integral part of the methodologies available to restorers, as has been demonstrated by experience at an international level in recent years.

Paolo Cremonesi is a chemist-restorer; he is the Scientific Co-ordinator for CESMAR7 (Center for the Study of Materials for Restoration); he teaches chemistry for restoration at En.A.I.P. in Padua and collaborates with the Opificio delle Pietre Dure in Florence; he carries out instruction and applied research with various entities, institutions and private laboratories.

Low pressure tables have now been around for several years, but while there exists great curiosity about them, still few in the restoration industry know much about their use, their potential and real capabilities. This volume outlines the basic principles of suction tables, offers instructions on how to build them and make correct use of them. Practical examples of a variety of techniques that can be carried out using this tool are also given.
