A cup is an open-top container used to hold liquids for pouring or drinking. Although mainly used for drinking, it also can be used to store solids for pouring (e.g., sugar, flour, grains, salt). Cups may be made of glass, metal, china, clay, wood, stone, polystyrene, plastic, aluminium or other materials, and are usually fixed with a stem, handles, or other adornments. Cups are used for quenching thirst across a wide range of cultures and social classes, and different styles of cups may be used for different liquids or in different situations. Cups of different styles may be used for different types of liquids or other foodstuffs (e.g. teacups and measuring cups), in different situations (e.g. at water stations or in ceremonies and rituals), or for decoration.
