As mentioned metal clay is a good option if you have a kiln. I think though you couldn't consider metal clay as a cold process ;) I get what youre after because it's something that has been on my mind too - I love the concept of cold connecting! LOVE the idea of a two part piece overlayed on the stone and riveted!! Must play with that one!
Anyway! There are a few methods of bezel setting for PMetalClay including the one mentioned (embedded bezel wire) - now I haven't done any of these yet but there are heaps of books out there with really good step by step advice - the outcome is pretty fantastic
You can also:
- rather than embed a bezel wire, simply attach ('contact') wire on with metal clay paste to the metal clay (syringe works best) (or if using an existing silver piece to attach your bezel wire to you should use oil PMC paste) and fire, set after firing
- press the fire resistant stone (check which stones, not all will fire and survive) into the clay so its surface just under the clay surface - fire. Will created a natural bezel 'lip' over the stone/glass as the clay shrinks but it must be so that the stones surface is below the clay surface enough to 'catch' when shrinking
- place your stone on the clay, syringe a lip over the edge of the stone making sure the paste is both covering where the bezel needs to be and touching the clay surface, fire
In all cases you need to let the piece cool off in the kiln, and don't quench as doing otherwise will most likely shatter or fracture the stone.
Let me know if you want me to recommend any books with certain methods as I have a fair few.
Hope you share your cold bezel results whatever you choose to do!
Good luck! Cynth :)
