Lynton’s conservation specialist, Dr Martin Cooper, and chairman, Dr Andrew Charlton, were invited to take part in the ‘Laser Cleaning Workshop for Art and Architecture’ which was held last October in Philadelphia at the School of Design, University of Pennsylvania. The workshop was attended by over 80 conservators, collection managers, architects, masonry contractors, and construction managers who had the chance to try out our Compact Phoenix system and learn about the current state of laser cleaning technology and its applications within the heritage field.
