I tried using the hot dip method of torch firing on some stainless steel bead chain. My thought was the enamel would not go inside the beads and the chain would remain flexible.
For the most part it worked, but I need to get some different enamel, with the correct coefficient of expansion for stainless. As you can see in the photo, most of the enamel came off as it cooled. I think it looks cool anyway.
