Ring sizer, Redy Pellets, ceramic and plastic, white, 22.5x17mm, size 6. Sold per pkg of 3.

Make perfectly sized, metal clay rings every time with the handy Redy Pellets ring sizer system. Form your ring, place the Redy Pellets sizer in the ring and fire as usual using a kiln or torch. As the metal clay sinters, it shrinks around the pellet, ensuring the ring forms to the exact diameter of a US size 6 ring. This revolutionary pellet doesn't shrink or burn during firing and is easily dissolved by placing the fired piece in water.

Precautionary Note: Do not empty water with dissolved Redy Pellets down a drain, as mixture will harden and lead to clogged drains. Pour most of the water onto the ground and allow remainder to evaporate. When dry, knock dried material out of the container into a trash can.

Sizing Note: Rings cannot be formed directly on the Redy Pellets since there will not be enough room for the 2-3% metal clay shrinkage. It is recommended to add 1-1/2 sizes when first forming to allow for shrinkage. Refer to manufacturer's instructions for additional information.
