Fold-forming a Spiral

I mentioned in my last post that if you hammer on an edge or on fold the metal will move in that direction.  It is a really cool process to see the metal move and bend.  It can also take a long time to hammer.  You have to anneal the metal frequently.

Here are some shots of making a spiral from copper.  I first sawed out a rough shape that was approximately 6 inches by 3/4 of an inch wide.

 I then unfolded the metal.

 I also enameled it in clear enamel on both sides.  The repeated heating brings out the gold highlights in the copper.
