I am curoius as to what color this is. I found it in the dirt and it is an old Brookfield. If you look at it at an angle, it makes a rainbow like it's covered with gas. Then if you look through it, it looks dark green. I can't find any acid around here, and I'm afraid to try and clean it any other way. This one brings the total to 25 that I have taken from the excavation piles. I need to really clean them, and then I will take a group shot. I have found several others that were chipped, but did not bring them home, as my wife already can't stand the complete ones.

Thanks Gene, for the reply. It was buried in a dump environment with a lot of rusty oily crap.
