These ceramic ring cores are ideal for controlling the shrinkage of metal clay and for firing your ring in to a perfect round shape - no need for hammering!

The shrinkage of rings will depend on the firing method and temperature but these cores will help keep the shape of the finished ring. Simply mould your ring (on average a couple of sizes larger than needed but this will depend on the clay used). When ready for firing place some ceramic firing tape around the core and place in your kiln. Do not quench in water, allow to air cool and then the ring will simply come off perfectly round! Unsure what size to choose, stuck between sizes - go for a smaller size rather than a larger as its easier to make the ring bigger after firing if its a little tight!
