Made with copper, this RingCore™ ring can be safely fired with your Copper Clays designs.
Your copper clay will sinter fully with the ring surface.
The textured surface offers a terrific grip for adding clay embellishments.
The ring size will stay consistent throughout the design, firing and finishing processes (without your having to calculate shrinkage and makes allowances for it),
and the smoothly finished interior of the ring will need almost no finishing--leaving you free to revel in the creative design of your ring.
