Will, You say your copper has been “sitting” for two days. What is
it “sitting” on? If your piece is lying on the bottom, you will
never get a decent etch. There are two things you need for a good
your piece needs to float image side down
the acid needs to agitate
Both can be solved quite easily. Take some double sided sticky tape
and tape the back of the piece to a piece of styrofoam. This will
act as a lovely little pontoon.
Get a cheap aquarium pump, and strap that puppy to the outside of
your plastic container. Plug it in and let it vibrate away. Now
the acid is gently agitating, taking away the little metal bits that
are etched by the copper.
I guarantee this will work.
