Abstract
Abstract The removal of old repairs made using metal flake paint, commonly referred to as bronze paint, has often been difficult to achieve from gilded wood and especially from oil gilded surfaces with similar solubility parameters. Conservators at the National Trust's Knole Conservation Studio in the UK treated gilded picture frames from the Knole House collection using an energy-attenuated Fotona (Dualis XS) Erbium:YAG laser, with fluencies between 0.5 and 1.0J/cm2, pre-wetted with hydroxyl and non-hydroxyl group-containing solvents. Comparisons of the effects of cleaning using only solvents and with the laser were made, and cross-sectional and media composition analysis carried out using optical microscopy, scanning electron microscopy with energy dispersive X-ray (SEM-EDX), Raman and Fourier transform infrared (FTIR) spectroscopies.
期刊介绍:
The Journal of the Institute of Conservation is the peer reviewed publication of the Institute of Conservation (Icon). As such, its aims reflect those of Icon, to advance knowledge and education in conservation and achieve the long term preservation and conservation of moveable and immoveable cultural heritage. The Journal provides a collective identity for conservators; it promotes and supports both the profession and professionalism. With international contributions on all aspects of conservation, it is an invaluable resource for the heritage sector. The specific aims of the Journal are to: 1. promote research, knowledge and understanding of cultural heritage conservation through its history, practice and theory 2. provide an international forum to enable and disseminate advances in research, knowledge and understanding relating to conservation and heritage 3. champion and support professional standards of heritage conservation in the UK and internationally 4. provide a permanent record of issues relating to conservation and heritage 5. be financially and operationally sustainable. To achieve these aims, the Journal invites contributions from all those involved in the conservation of cultural heritage and related activities. Areas of interest include understanding cultural heritage materials and their degradation; subject reviews and histories of cultural heritage materials and conservation treatments; new, innovative or improved approaches to conservation and collections care theory, practice, communication, management and training; case studies demonstrating new, innovative or improved approaches; and conservation in its wider context. Submitters are encouraged to demonstrate how their work is of practical application to conservation. To maintain professional standards and promote academic rigour, submissions of articles and shorter notices are subject to an anonymous peer review process.
