The Mabel 24 Piece Dinner Set and Liana 26 Piece Breakfast Set are made of stoneware and are 100% Turkish made. Stoneware is a clay-based material used in the production of plates and bowls, fired in the kiln at 1100-1300 degrees. It is much stronger than ceramic and absorbs less water compared to ceramics. Being fired at a higher temperature, it can be safely used in the microwave, oven, and dishwasher for many years.
