The next time you’re preparing to glaze teapots, stop by your local hardware store on your way to the studio and pick up some foam earplugs. Before dipping your teapot in the exterior glaze, plug the tip of the spout with a deflated earplug to prevent it from filling with glaze. Simply roll the earplug between your fingers to compress the foam, and then insert it into the spout (1). The earplug will expand and snugly fill the opening. Dip your teapot as usual (2). After the glaze has dried, remove the earplug, and you will have a perfectly glazed teapot spout (3).
