It's All Done With Mirrors
In case you've ever wondered how long it takes a mirror to lose its silvering (reflective backing), there's now a short paper reporting an experiment on the subject, on TIGHAR's Ameliawiki (or Ameliapedia) at http://tighar.org/wiki/Deterioration_of_a_Mirror%27s_Silvering. The wiki is the vehicle we're using to develop, organize, and present a wide range of data pertinent to the Earhart project, including archaeological site reports, artifact and other analyses, historical data, environmental data, etc. etc. The mirror study was occasioned by finding (in 2001 and 2007 on the Seven Site) pieces of what we're pretty sure was the mirror from a woman's compact from the 1930s.
