Gustav Berger, internationally recognized as one of the most innovative thinkers in the field of painting conservation, offers the reader fresh insights into his deliberations over conservation problems and treatments. He is best known for his development of BEVA, an adhesive specifically formulated for use in conservation, and for his groundbreaking research in the cracking of paint. Included in this book are updated and revised descriptions of landmark investigations and approaches, as well as observations on how the results have fared. Anyone interested in the development of modern conservation practice will find this volume an invaluable reference and a fascinating read. 'The wealth of experience brought together in one volume and the striking contribution that Berger has made as an independent conservator make this book worth reading.'
