I’ve been fooling around with colored porcelain components for a while, and usually make them into pendants or earrings. Here’s my first ring which might not be a practical application, but it was fun to try. The metal is bronze, my current favorite.
I decided to go with a prong setting in bronze. The basic diagram (not to scale) is above. I cut a piece of wire, soldered it closed with hard solder and shaped it with a round mandrel. Then I laid out the prongs in the 2, 4, 8, and 10 O’clock positions and soldered them on with hard solder. (The red dotted line is an estimate of the size of my ceramic focal so I could be sure that I cut the prongs long enough.) Then I cut, shaped and filed the shank and soldered it on with medium solder. Here’s a tutorial that shows something similar to what I did.
I now have a small kiln that fires to cone 6, so I expect to be making more ceramic components in the future.
