      (Italian: “gypsum,” or “chalk”), fluid, white coating composed of plaster of paris, chalk, gypsum, or other whiting mixed with glue, applied to smooth surfaces such as wood panels, plaster, stone, or canvas to provide the ground for tempera and oil painting or for gilding and painting carved furniture and picture frames. In Medieval and Renaissance tempera painting, the surface was covered first with a layer of gesso grosso (rough gesso) made with coarse, unslaked plaster, then with a series of layers of gesso sottile (finishing gesso) made with fine plaster slaked in water, which produced an opaque, white, reflective surface.

      In the 14th century, Giotto (Giotto di Bondone), the notable Italian painter, used a finishing gesso of parchment glue and slaked plaster of paris. In medieval tempera painting, background areas intended for gilding were built up into low relief with gesso duro (hard gesso), a less absorbent composition also used for frame moldings, with patterns often pressed into the gesso with small carved woodblocks. Modern gesso is made of chalk mixed with glue obtained from the skins of rabbits or calves.
