The first thing I did when it had cooled enough was to unroll and flatten the copper with my fingers. It was a little uneven at spots, so I used a pair of pliers to help. Don't get too carried away, the copper will work-harden, and you'll have to anneal it again. Once the copper was flat, I used a file to get the edges clean and nice. Then I used 220 grit sandpaper to remove the oxide layer and shine it up some. For some projects, working up to a finer grade of sandpaper, then polishing could be used. I was using a piece of this as an electrical contact, I didn't worry too much about the finish, it was to be tinned with solder before use.

We're done now. Time for you to think of something made with copper!
