gesso

gesso
   Plaster or a fine plaster-like material made of gypsum, which is also called whiting, used for sculptures. An especially versatile medium in reliefs, gesso can be either a material cast in a mold or a material of a mold, a material to be modeled, or carved, or attached to something else. When used for molds into which molten metal is poured, it must be hardened with sand as a grog. Gesso may also refer to such a gypsum material mixed with an animal-hide glue and used as a ground for painting. For this latter use, it is usually applied to the surface of a wood panel or sculpture to become the surface on which an artist paints. It was used by Gothic and Renaissance panel painters, and is still used today. Oxgall (or another wetting agent) can be employed to eliminate pin-holes in gesso surfaces by mixing it into the gesso before the gesso is applied. Like all other dusts, airborne gesso is hazardous to breathe — every user should wear an appropriate dust mask. Also see slip and stucco. (pr. JES-soh)
