The pellet is made from a special material that does not shrink or burn during firing. As the metal clay sinters, it shrinks tightly around the pellet so the ring is the exact diameter of the pellet after firing. After cooling, the ring is put into water to dissolve the pellet. \u003c\/span\u003e\u003cdiv\u003e\u003cspan style=\"font-family: 'trebuchet ms', geneva; font-size: small;\"\u003e \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\u003cspan style=\"font-family: 'trebuchet ms', geneva; font-size: small;\"\u003eWith this mould you can cast your own Ring Sizers as and when needed.
