It can certainly be disconcerting when that really big pottery piece you thought you made emerges from the glaze kiln, especially if the clay body has a high shrink rate, like porcelain!

Use our Clay Shrink Calculator to help determine how large to make your pottery piece so that its final size (after bisque and glaze firing) is close to your expectations.
