Stoneware serving plate designed with mottos from our Book Lovers collection. Stoneware is a clay-based material used in the making of plates and dishes, fired and baked at 1100-1300 degrees. It is much more durable than ceramics and absorbs less water compared to ceramics. Due to being baked at higher temperatures, it can be safely used in the microwave, oven, and dishwasher for many years.
