Julias 26-piece breakfast set is made of stoneware and is 100% Turkish-made. Stoneware is a clay-based material used in making plates and dishes, baked at 1100-1300 degrees to achieve durability. It is more resistant and less absorbent than ceramic. Due to being fired at a higher temperature, it can be safely used in the microwave, oven, and dishwasher for many years.
