Fiesta makes this sixteen-ounce mug in Newell, West Virginia, from vitrified china that the company describes as lead safe, and the color is Lavender, the shade it chose for its ninetieth anniversary. The base is notched so that one mug sits neatly on another, and the mug measures 3 7/8 inches across and 3 7/8 inches high. It can go in the dishwasher, the oven and the microwave.
