A plate is a broad, mainly flat vessel on which food can be served. A plate can also be used for ceremonial or decorative purposes. Most plates are circular, but they may be any shape, or made of any water-resistant material. Generally plates are raised round the edges, either by a curving up, or a wider lip or raised portion. Vessels with no lip, especially if they have a more rounded profile, are likely to be considered as bowls or dishes, as are very large vessels with a plate shape. Plates are dishware, and tableware. Plates in wood, pottery and metal go back into antiquity in many cultures. In Western culture and many other cultures, the plate is the typical form of vessel off which food is eaten, and on which it is served if not too liquid. The main rival is the bowl. The banana leaf predominates in some South Asian and Southeast Asian cultures. A plate is typically composed of: The well, the bottom of the plate, where food is placed. The lip, the flattish raised outer part of the plate (sometimes wrongly called the rim). Its width in proportion to the well can vary greatly. It usually has a slight upwards slope, or is parallel with the base, as is typical in larger dishes and traditional Chinese shapes. Not all plates have a distinct lip. The rim, the outer edge of the piece; often decorated, for example with gilding. The base, the underside. The usual wide and flat European raised lip is derived from old European metalwork plate shapes; Chinese ceramic plates usually just curve up at the edges, or have a narrow lip. A completely flat serving plate, only practical for dry foods, may be called a trencher, especially if in wood. Plates are commonly made from ceramic materials such as bone china, porcelain, earthenware, and stoneware, as well as other traditional materials like, glass, wood or metal; occasionally, stone has been used. Despite a range of plastics and other modern materials, ceramics and other traditional materials remain the most common, except for specialized uses such as plates for young children.
