This 50-piece Dining Set, consisting of Julia 24 Piece Dinner Set and Julia 26 Piece Breakfast Set, is made of stoneware and is 100% made in Turkey. Stoneware is a clay-based material used for making plates and dishes that is fired and baked in kilns at temperatures ranging from 1100-1300 degrees. It is much more durable and less porous than ceramics. Due to being fired at higher temperatures, it can be safely used in microwaves, ovens, and dishwashers for many years.
