Here are my results:
The top ornament was made with the COPPRclay (it was under-fired), and bottom was made with Art Clay Copper.  You can see the pitting that occurred when I tried to polish the COPPRclay with a wire brush (both ornaments were polished using only a wire brush).  The COPPRclay did shrink more than the Art Clay Copper too:
Here is another photo of the wire-brushed ornament made with Art Clay Copper: 
 And now for fun with adding a patina (part of the reason I wanted to work with copper clay so badly)!!!  This patina was created using only vinegar and salt.  I put some salt on the ornament and placed a vinegar soaked cotton pad on it.  The patina will wash off, so you might want to add a sealer to protect your desired finish.

Well, I was excited to share my finished results with you!  Hope to have more copper pieces to share soon!  Thanks for stopping by:)
P.S.  While doing some of my research, I found there are lots of different copper clays out there....you can even make your own!  Also, check out the work of this amazing metal clay artist!
