Description

The relationship between archaeology and conservation has long been complex and, at times, challenging. Archaeologists are often seen as interested principally in excavation and research, while conservators are concerned mainly with stabilization and the prevention of deterioration. Yet it is often initial conservation in the field that determines the long-term survival and intelligibility of both moveable artifacts and fixed architectural features.

This user-friendly guide to conservation practices on archaeological excavations covers both structures and artifacts, starting from the moment when they are uncovered. Individual chapters discuss excavation and conservation, environmental and soil issues, deterioration, identification and condition assessment, detachment and removal, initial cleaning, coverings and shelters, packing, and documentation. There are also eight appendixes.

Geared primarily for professionals engaged in the physical practice of excavation, this book will also interest archaeologists, archaeological conservators, site managers, conservation scientists, museum curators, and students of archaeology and conservation.

About the Authors

Corrado Pedelì is a senior conservator-restorer employed since 1985 at the Department of Cultural Heritage of Aosta Valley (northwestern Italy), where he is primarily responsible for conservation projects and scientific direction of conservation sites, monuments, and objects. He specializes in first aid and emergency conservation techniques on archaeological sites. Since 2004 he has been a consultant for ICCROM (International Centre for the Study of the Preservation and Restoration of Cultural Property), teaching several courses in the Middle East, Asia, southeastern Europe, and Italy.

Stefano Pulga is a conservator in private practice. He started as a conservator trainee at the Laboratory of Ottorino Nonfarmale in Bologna, Italy, then at CREPHART laboratory of Theo Antoine Hemanès in Geneva, Switzerland. Pulga has been involved in numerous conservation campaigns for archaeological heritage and monuments throughout Europe. Under the direction of the Department of Cultural Heritage of Aosta Valley, he has undertaken or coordinated the conservation work on various castles in the region (Fenis, Clay, Ussel, Morgex, Quart, Issogne, Graines) and Roman monuments in Aosta (the Pretorian gate and the city fortification walls).
