Photographic fixer works by removing the light-sensitive silver from the paper, so the silver compound remains in the fixer bath. If you use fixer, you will discover that one of your terminals (the anode, I think) will turn silver colored. You can actually peel off the flakes of silver that form on the terminal.

I'm taking a photography class - I'm not sure how much fixer I can "borrow", but I'll try it. -- _ /| When you link up to a VAX or UNIX without a "shell", you're linking \'o.O' with every other VAX or UNIX that the admin has been with! =(___)= Stoplights timed for 35 MPH are also timed for 1,244,740 MPH!!!!

Apparantly, they can recover enough of the silver to make it worthwhile salvaging. You have also demonstrated a simple electroplating principle with your experiment.
