I'm sure there's someone out there with Bellcore "listening". How do 
     we get this paper??

Folks:
     
Sometime ago, Bellcore published a study on copper oxidation: "The Surface 
Composition of Copper with Indoor Exposures Ranging from 3 to 49 Years" 
Schubert and D'Egidio, Corrosion Science 1990. They found that the copper 
corrosion is similar to aluminum, to first order it passivates. After about 40 
years the oxide thickness is only about 0.4 mils. Although the an indoor 
environment was used, it was none the less, very aggressive!
