Drinkware or Beverageware is a general term for the class of vessels from which people drink.
Glassware is a class of objects that include drinkware made from glass as well as other items.
Stemware is a subcategory of drinkware that stand on stems.
A glass is a drinking vessel made from glass. Glasses are often clear, but are sometimes coloured, or printed or etched with decorations. Compared with a cup which is defined as having a handle and hold exactly one cup of liquid, a glass stands taller without a handle and usually holds more liquid.
A beer stein or Steinkrug is a traditionally German beer tankard or beaker, made of pewter, silver, wood, porcelain, earthenware, stoneware or glass.
One variation is the double martini glass which is taller and wider at the opening than a standard martini glass.
Another variation is a Stub glass, which is identical to the martini glass, except that the base is attached directly to the bowl, removing the fragile stem. These glasses are used in situations where breakage and theft of regular martini glasses occurs frequently, such as a bar serving college students.
Note that the word "antiquing" may also refer to the art of making an object appear antique through distressing or applying an antique looking paint application.
