This presentation presents an overview of polymer coatings for outdoor cultural heritage. The presentation defines cultural heritage, examines deterioration causes, discusses polymer usage for protecting bronze and stone monuments, and offers a look forward. The presentation was created for the Waterborne Symposium, New Orleans, La. March 1-4, 2011.
26. Biological Organisms Grow in an amazing variety of environments Micro-organisms can: produce corrosive compounds consume compounds that inhibit corrosion The presence of biological organisms almost always increases corrosion rates in metals and deterioration rates in stone.
57. “…the need to build broad based partnerships between conservation scientists and scientists from universities, national laboratories, industry and other institutions...”CHEMISTRY AND MATERIALSRESEARCH AT THE INTERFACEBETWEEN SCIENCE AND ARTReport of a Workshop Cosponsored by theNational Science Foundation and the Andrew W. Mellon Foundation, July 6-7, 2009
58. Engage interdisciplinary teams to apply new polymer systems that can help preserve cultural objects for future generations.
59. Create collaboration and outreach through conferences, publications, and social media to bring together new teams and unique approaches.
Cultural heritage is deteriorating from both natural and manmade causes.Mausoleum at La Ricoleta in Buenos Aires, Argentina. Here we see the results of water damage, stucco loss, and vegetation.
The National Center for Preservation Technology and Training is an office of the National Park Service.It was created by an act of Congress in 1994 to develop or transfer technologies into the field of historic preservation. We work in the fields of architecture, engineering, archeology, collections, materials conservation, and landscapes.
Nondestructive testing is a tool for preservationists to study cultural heritage.The surface loss on this stone balustrade is an example of problems that could be approached with nondestructive testing. What is the nature of the flaws in this stone? Are salts and moisture contributing to the damage? Can stone consolidants be used to prevent further loss?
Cultural heritage is defined as the material artifacts and intangible attributes of a people or a culture that are inherited from past generations.
Cultural heritage can take the form of historic buildings and structures.Historic structures may include fine architectural examples or places of historic significance.Above, Slave quarters at Magnolia PlantationBelow preservation of brick wall, part of NCPTT sponsored workshop on fortificiations.
Cultural heritage includes archeological sites. Here we see NCPTT student intern Fran Ritchie working at Magnolia Plantation, Louisiana, ground truthing a location that was recorded with ground penetrating radar.
Cultural heritage can include fine arts or other collections, like the ethnographic objects seen here. NCPTT has funded Dr. Timberly Roane at University of Colorado , Denver, to study use of micro-organisms for removal of mercury and arsenic once used as pesticides on these objects.
The way a culture interacts with the landscape may also be considered cultural heritage. Planned and maintained landscapes, such as a cemetery or an historic park are cultural heritage.
Natural decay cannot be properly treated without understanding of the chemical and physical causes.This grave marker has suffered surface loss likely due to rising damp and moisture issues.
