This publication contains papers from the BAPCR Conference held 7 October, 2016 at the Wallace Collection, London. Papers include talks on past issues and current problems. They examine approaches to restoration and the presentation of paintings in the nineteenth century as well as technical analysis and research into nineteenth-century artists' materials and working methods. The conference also examined the challenges faced by today's conservators when treating works from this period. The papers are illustrated with a large range of case studies.
