The shape of the Cup is usually close to the cylinder or to the truncated cone, but there are glasses of more complex shape. The main difference between the glass from other types of dishes is the absence of a handle. The glasses also come in faceted. The ratio of the height of the glass to the diameter of the base is about 2:1, and it is close to the size of a human palm. The volume of the glass is usually 200-250 cm3. Smaller glasses are often called cups, and very small ones are called stacks. In everyday life, it is believed that an ordinary faceted glass, poured to a smooth rim, holds 200 ml, poured vzylyan, that is, to the brim, - 250 ml. In the old Russian measures of volume of liquid bodies (mainly, state vodka) 12 glasses = 1/4 buckets, that is 3 l, from which the volume of a glass is 250 ml. Most often glasses are made of glass. This practice is reflected in the fact that in some languages, such as English, German, French, the words glass and glass are homonyms: glass, Glas, verre. Glasses are, however, also plastic, paper, ceramic and metal. There are glasses transparent (glass, plastic) and opaque (paper, plastic, metal), reusable and disposable (from paper or plastic), folding (from several rings).
