A picture frame is a container for a picture, such as a painting or photograph, intended to enhance it, make it easier to display, or protect it. Picture frames have traditionally been made of wood, which is still the most common and most prestigious material, although other materials are also used, including aluminum, plastics or polystyrene, even sea shells. A picture frame may be of any colour or texture, but gilding is common, especially on older frames. Some picture frames have elaborate mouldings which may relate to the subject matter. Complicated older frames are often made of moulded and gilded plaster over a plain wood base. The picture frame may contain a pane of glass or a plastic glass substitute such as Plexiglas, to protect the picture. In some instances where the art in the frame is dispensable or durable, no protection may be necessary. Glass is common over watercolours, rare over oil paintings, except very valuable ones in some museums. Glass may be treated with coatings, the most common being UV filters.
