The bowl, a common open-top vessel in
many cultures, is used to serve food, and is sometimes
also used for drinking and storing other items. They
are generally small and shallow, although some, such
as punch bowls and salad bowls, are larger and are sometimes
intended to serve many people at once. Bowls have existed
for thousands of years. Modern bowls can be made of
ceramic, metal, steel, wood, plastic, and other materials.
Their appearance can range from very simple designs
of a single color to sophisticated artwork.
