Trim around the leaf using a craft knife or pin tool, then gently peel off the leaf for your second earring or use a new leaf if you wish. Then allow to dry and fire according to the clay you are using.
Fire, brush with a brass brush (careful with the wires) work harden the wires and polish.
Unfortunately the firing of my Copprclay was an "Epic Fail" (to coin the latest phrase that my two boys have been using). Arrggh! I have good luck and bad luck with CopprClay, not sure what went wrong in this case. I will try again and refire it when I have some new carbon. I love the texture of the Copprclay but its reliability is not there for me, PHOOEY.
Above is a photo of the failure. Metal clay doesn't fire properly it has a "feel" to it. It may sound like metal and can even be burnished but it won't hold up. The photo shows one example, the copper came out with a dark colour and as you can see it is brittle. Sometimes refiring it will work. I will let you know what happens with these pieces.
