Hi

I was wondering if anyone knows how to solder a joint on a pendant very quickly, I want to solder a small piece of tubing on the back of a pendant but must keep the heat transferred to the pendant at a minimum. This is because the pendant has a fine layer of gold foil fused to it and any heat transferred to it will diminish the gold into the silver.

Looking around the only option seems to be some form of welding but this seems quite expensive, does anyone have any suggestions?

Thanks for any help.

ah, tried to upload a photo but I am unable as I haven't reached 5 posts yet.
