Join APT DC for a presentation on methods of cleaning historic masonry. This lecture, hosted by SGH, is being presented by Elena Charola, a research scientist for the Smithsonian Institute’s Museum Conservation Institute and a scientific consultant for the World Monuments Fund. She is also a professor at the University of Pennsylvania School of Design. Ms. Charola’s projects have spanned the globe and she has lectured extensively for various organizations and universities.

The presentation covers cleaning of historic masonry. Cleaning is one of the most traditional and unquestioned conservation interventions to which historic masonry is subjected. Since the historic center of Paris was sandblasted in the 1950s, various methods have been devised, becoming fashionable, and subsequently rejected, The presentation discusses these methods, such as grit blasting, water washing, application of chemical poultices, and lasers among others, as well as the changes and improvements that all of them underwent over the past sixty years. Most importantly, the rationale that should guide our choice when selecting a cleaning approach is considered.

Doors open at 6:30. The nearest Metro Station is Farragut North (Red: L Street Exit). Metered parking is available beginning at 6:30. The presentation will begin at 7. 1 LU/HSW/PDH has been requested for this lecture. Please select the appropriate registration to receive credit. Light refreshments will be served.
