Modern synthetic paint that combines some of the properties of oils and watercolour. Most are water-based, although some are oil compatible, using turpentine as a thinner. When it became available to artists in America around 1936 it was the first new painting medium in centuries and has become a serious rival to oil paint because of its versatility. Acrylic paints can be used on nearly any surface. The water-based nature of acrylic paint allows for easy application and rapid drying time: acrylic paint dries in a matter of minutes, as opposed to the many months required for oil-based paints. Once the paint has been applied to a surface, the water evaporates, leaving behind the synthetic resin (and pigment), which is no longer water-soluble. Visually, acrylic-based paints can appear to be very similar to oil-based paints, but they cannot rival the rich, translucent nature of oils.

The arrangement of elements or details in an artefact or a work of art.

Refers to either the material used to create a work of art, craft or design, i.e. oil, bronze, earthenware, silk; or the technique employed i.e. collage, etching, carving. In painting the medium refers to the binder for the pigment, e.g. oil, egg, acrylic dispersion. The plural form is media.

A medium in which ground pigments are mixed to produce a paste or liquid that can be applied to a surface by a brush or other tool; the most common oil used by artists is linseed, this can be thinned with turpentine spirit to produce a thinner and more fluid paint. The oil dries with a hard film, and the brightness of the colour is protected. Oil paints are usually opaque and traditionally used on canvas.

A drawing medium of dried paste made of ground pigments and a water-based binder that is manufactured in crayon form. The term also refers to a picture or sketch drawn with this type of crayon.
