>"** The tarnish that forms on silver is "silver sulphide" - an insulator. "   
      
   So if you got acid rain your silver is brown ? lol   
      
   I read about it being sulpher and not oxygen but where does it get the sulphur   
   ? In a metropolitan area I can see where (almost literally) but in normal   
   places fit for human habitation, there is probably not much sulphur in the air.   
      
   I thought the major source of SO2 in the air was burning of shitty fossil   
   fuels like cheap coal.
