This cute 2 piece egg poacher works in your microwave. Spray bowl with oil (butter). Crack egg into bowl and pierce yolk with a knife to release steam during cooking. Lid comes with vent hole. Just 30 seconds, and voila! This is a trippy glaze. Shades of blues and green with hints of purple on a dark brown base color. This round was made with our speckled clay. As always, use care when handling hot objects. Glaze design may vary slightly from the one in the picture.
