Thanks for all the suggestions - the solution is not olive at all. It
appears to be a clear, bright green. I would have called it "lime
green" but its not far from emerald. So it looks like I need to find
some concentrated H2O2. Anyone know a source in the Seattle area?
By the way, I think there was some etching going on - the surface of
the copper took on that characteristic flat texture you get when
etching first starts. Of course, this was after 45 minutes... sigh...
