This metal stick can be used to round a ring when it has lost its round shape. Silver clay is still very soft after firing and can often be pinched around by hand. A rubber or wooden hammer can also be used to give a ring its shape back.
Without size indication.
NOTE: If the silver is hammered with a rubber mallet, the ring will slowly increase. You can use a metal hammer to make the ring bigger (fast) and harder. You will then get a hammered structure that you can leave the way it is or u need to sand and polish.
