Holloware (hollowware, or hollow-ware ) is metal tableware such as sugar bowls, creamers, coffee pots, teapots, soup tureens, hot food covers, water jugs, platters, butter pat plates, and other items that accompany dishware on a table. It does not include cutlery or other metal utensils. Holloware is constructed for durability. It differs from some other silverplated items, with thicker walls and more layers of silverplate.
Dining car holloware is a type of railroad collectible (railroadiana). The relative value of pieces depends on their scarcity, age and condition, and the popularity of the trains on which the items were used.
