Tea leaf ironstone dishes are named for their decorations. There was a superstition that it was lucky if a whole tea leaf unfolded at the bottom of your cup. This idea was translated into the pattern of dishes known as tea leaf. By 1850 at least twelve English factories were making this pattern, and by the 1870s it was a popular pattern in many countries. The tea leaf was always a luster glaze on early wares, although now some pieces are made with a brown tea leaf. There are many variations of tea leaf designs, such as Teaberry, Pepper Leaf, and Gold Leaf. The designs were used on many different white ironstone shapes, such as Bamboo, Lily of the Valley, Empress, and Cumbow. The tea leaf pattern pictured a luster tea leaf on a white dish.
