I've gone through a lot of jewelry phases. First [besides the plastic beads] was 'junk jewelry' or repurposing cans and bottles caps and things like that. I'd take apart calculators and computer chips and odd looking industrial things and make bracelets and earrings and necklaces out of them. Then I briefly transitioned into a glass soldering phase, which is what this post is about. I don't have any steps pictures, but they really are easy-peasy to make.
Supplies: Soldering gun, solder, flux, microscope slide/half marble, copper tape, jump ring, cord or chain, art for backing
1. Cut the piece of art you want to show through the marble to fit.
2. Secure art to marble by backing with copper tape, the more you smooth it down the less bumpy the back will be and the more secured it will be. Make sure it covers sides as well!
3. Smear flux on tape, cover the tape with solder, attach jump ring [ also smear flux on jump ring]
4. Attach to cord or chain.
5. Work it girl!

this older post.
[note: not all metals will adhere with the solder, so be sure to check that your jump ring will]
