I bought a job lot of silver bits a while back, one of which was a Victorian brooch with some lovely engraving featuring cannabis-like leaves and a little bird. Unfortunately the pin had come off, leaving the C-clasp behind, plus a rough blob of solder where the pin had joined onto the back. I used a pair of pliers to curl the C-clasp and form a closed loop, and then bent the loop back so that it was near-parallel to the surface of the brooch. Then I added a jump ring. I used the file that had come with my new silver testing kit to smooth off the solder. So here is the result, front and back:

The back looks less than ideal but at least it’s reasonably smooth – and I made a pendant from something that would have ended up lying in a drawer or being sold for scrap.
