High Temp Ring Mandrels - Size 3-13

Ring mandrels are shaped forms you build a polymer clay ring around and then bake it on, so the finished ring holds an accurate size and an even, round shape. This full set covers every US/CA size from 3 to 13.

Each mandrel is oven-safe up to 150°C (300°F), so the ring bakes right on it. You can also use them to shape metal clay rings, though they cannot be fired in a kiln. If you are not sure of a size, check a ring size conversion chart before you start.
