A bowl is a round, open-top container used in many cultures to serve food, and is also used for drinking and storing other items. They are typically small and shallow, although some, such as punch bowls and salad bowls, are larger and often intended to serve many people.Bowls have existed for thousands of years. Very early bowls have been found in China, Ancient Greece, Crete and in certain Native American cultures. Modern bowls can be made of ceramic, metal, wood, plastic, and other materials. Their appearance can range from very simple designs of a single color to sophisticated artwork.
