This dinnerware is inspired by authentic diner pieces. It was originally made by the Buffalo China company of New York, founded in 1901 to produce china items offered as premiums by a soap manufacturer. Extremely durable, the stoneware dinnerware became popular at roadside diners along the new U.S. highways and has since become a classic. Ours is inspired by a pattern that dates from the 1940s. The creamy white is the natural color of the clay. Oven, microwave and dishwasher safe.
