		<description><![CDATA[In 2002, researchers from North Dakota State University received funding from the NCPTT to study protective coatings for outdoor bronze sculpture and ornamentation.  Previous research had shown that the most protective coatings tend to be impervious to conventional solvent removal techniques and that standard mechanical removal methods damage bronzes and their patinas.  This study evaluates new solvent removable coatings and compares their protection to the currently used systems.]]></description>

		<description><![CDATA[For conservators working with iron, rust is always a consideration.  In museum collections or in our homes, we easily encounter rusty fences, grates, car parts, artwork and collectibles.  Iron oxide (commonly called rust) results from the natural oxidation of iron by oxygen.  Some metals, like bronze, can form a protective layer of corrosion products called [...]]]></description>

		<description><![CDATA[In this episode, Jason Church speaks with Curtis Deselles, an intern with the Materials Research program at NCPTT, discusses the use of eddy currents and eddy current technology in conservation science. Mr. Deselles has built several eddy current analyzers, custom software, and presented on this topic at a non-destructive conference in St. Louis.<br /><br />
NCPTT has been using eddy current technology in preservation and will be bringing this tool to the iPhone platform in 2010. <a href="http://ncptt.nps.gov/Podcasts/archive/Preservation-Technology-Episode-8-Eddy-Currents.mp3">Download Episode 8 as an mp3</a> or <a href="http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=285727030">subscribe via iTunes</a>.]]></description>
