Opis

Conservation practitioners seek predictable and successful procedures and treatments for controlling corrosion of heritage metals that conform to aesthetic and ethical boundaries set by prevailing cultural, historical, and archaeological contexts. Understanding metallic corrosion and its prevention is informed by scientific research provided by heritage scientists, conservators themselves and, to a lesser extent, corrosion scientists who may be in academia or industry.Bridging the Gap: Corrosion Science For Heritage Contexts explores the decision-making processes for preserving heritage metals and examines the collaborative, interdisciplinary relationships that underpin them.Through themed chapters, the book is designed to develop and strengthen collaboration between these three groups of professionals, creating a synergy that benefits research and practice for the preservation of heritage metals. It builds an overview of metals conservation across a broad range of heritage contexts, from indoor museum displays to fixed outdoor structures and moving objects. Researchers and practitioners provide critical insights into corrosion problems within heritage, current corrosion mitigation procedures and the evidence supporting best practice guidance.The book will be a valuable reference resource for corrosion and corrosion protection scientists; heritage preservation scientists; conservation practitioners and students studying preservation of cultural objects.
