Attaching a kiln-resistant kanthal wire to a gold or copper

[tss_happens]

Hi guys, I started to make porcelain jewellery. Now I have a task to attach beautifully a porcelain piece to copper or golden base. I have this way in mind:
1. Object: Firing a porcelain piece with a loop of a kanthal wire inside;
2. Base: Taking the copper or gold base;
3. Junction: Melting a small piece of gold into a drop on the copper / gold base and dipping the loop of a kanthal wire in it; according to my plan it should cool down and stay like that.

As soon as I am zero in this topic: tell me where I fail?

edit: ok now I've read that copper is toxic?
