Steps 14-16
14. Cover the back of the metal with duct tape. This prevents the etchant from attacking the back of the piece.

15. Mount the piece onto a piece of 1/2-inch plastic foam using double-stick carpet tape.

16. Pour the etchant (ferric chloride, in this case) into a glass dish on top of 1-2 fish tank pumps. The pumps keep the system vibrating, which eliminates the development of bubbles on the piece. Plug in the pumps.
