Holloware (hollowware, or hollow-ware ) is tableware such as sugar bowls, creamers, coffee pots, teapots, soup tureens, hot food covers, water jugs, platters, butter pat plates, and other metal items that go with the dishware on a table. It does not include flatware. Holloware is constructed to last a long time. It differs from some other silverplated items in being made 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 the items were used on.
