ERNST serving dish in glazed stoneware is a decorative dish that is available in two sizes. The series also includes bowls. Sometimes stains of coffee and tea occur, to remove these mix bicarbonate, baking soda or washing-up liquid in hot water and let it stand for a couple of hours, then wash them out and rinse thoroughly. All our stoneware can be used in all types of ovens, including microwave ovens. If a plate/bowl has been in the fridge, it should not be put in the microwave directly.
