I have been on the hunt for Ferric Chloride to etch some jewelry pieces. Radio Shack used to carry it. Can anyone tell me where to find some?? Or what else works as well? I was told to use Muric acid, but that is a highly toxic chemical and although I have it, I haven't opened it.

This mobile has over 140 butterflies. I was so tired of cutting out butterflies. It hangs from an electric gear motor that spins it slowly in someones home now.
