2 good thoughts, thanks. I'm using an old Mr. Coffee to keep things warm....it's the price I pay for living in Montana in the winter. Anyway, last night, when I pulled a piece out, I noticed that the etching was copper where the piece was in contact with the bottom of the pot, and brass where the piece was away from the bottom. I also heard that putting steel wool in the solution will help "absorb" (for lack of a better term) the excess copper ions?? I'm going at it again today and will keep you posted. ITMT, if anybody has any other answers, I'd appreciate it. Thanks
