I've been doing versions of this shape in different materials over the years. This one is scrap components brazed in a green sand mold and ground smooth. I was casting around for ideas to present the shape sculpturally, frame or plinth for example were too intrusive, so I decided to give it a sort of nominal shelf.

I am trying to make a hollow-form ring (from silver sheet), but am having troubles with my solder seams popping open. :o( Initially, it seems that my solder joints have flowed pretty well, but when I spend a bit of time hollowing out the band they split.
