This handmade and hand-painted pottery is fired at temperatures up to 3,000 degrees Fahrenheit, making it not only durable but impervious to abrasives and resistant to cracks and chips. All pottery is intended for everyday use and is lead/cadmium free... safe to use for food or drink. All pieces are safe for the refrigerator, oven, microwave and dishwasher - always allow them to come to room temperature when going from the extreme of the refrigerator/freezer to oven. Maximum suggested temperature is 450°. Easy to clean – the glaze provides excellent food cleaning properties. Great as gifts and will have value for years to come. Enjoy!
