Mixed media (oil, spackle, charred driftwood, glass, crushed graphite, and canvas collage on canvas etc, etc.) in visual art, refers to an artwork in the making of which more than one medium has been employed.
There is an important distinction between "mixed-media" artworks and "multimedia art". Mixed media tends to refer to a work of visual art that combines various traditionally distinct visual art media. For example, a work on canvas that combines paint, ink, and collage could properly be called a "mixed media" work - but not a work of "multimedia art." The term multimedia art implies a broader scope than mixed media, combining visual art with non-visual elements (such as recorded sound, for example) or with elements of the other arts (such as literature, drama, dance, motion graphics, music, or interactivity).
Many interesting effects can be achieved by using mixed media. Often, found objects are used in conjunction with traditional artist media, such as paints and graphite, to express a meaning in the everyday life. In this manner, many different elements of art become more flexible than with traditional artist media.
