Fixative – A solution, usually of shellac and alcohol, sprayed onto drawings of pencil, chalk and pastels, to prevent their smudging or crumbling off the support.
Foreshortening – The diminishing of certain dimensions of an object or figure in order to depict it in a correct spatial relationship. In realistic depiction, foreshortening is necessary because although lines and planes that are perpendicular to the observer’s line of vision (central visual ray), and the extremities of which are equidistant from the eye, will be seen at their full size, when they are revolved away from the observer they will seem increasingly shorter. Thus for example, a figure’s arm outstretched toward the observer must be foreshortened–the dimension of lines, contours and angles adjusted–in order that it not appear hugely out of proportion. The term foreshortening is applied to the depiction of a single object, figure or part of an object or figure, whereas the term perspective refers to the depiction of an entire scene.
Fresco – The art of painting on freshly spread plaster before it dries, or in any manner.

There are licensing agents who specialize in negotiating deals with makers of porcelain, giftware, stationery etc. Artists should be aware of the difference between selling a license and selling their copyright in a work.
Linear Perspective – A method of depicting three-dimensional depth on a flat or two-dimensional surface. Linear perspective has two main precepts: 1. Forms that are meant to be perceived as far away from the viewer are made smaller than those meant to be seen as close 2. Parallel lines receding into the distance converge at a point on the horizon line known as the vanishing point.
Mannerism – A deliberate simulation or exaggerated display.
Medium – Used to describe either the material used to create a work of art (such as oil, acrylic, pencil, water-colour, charcoal, stone, cloth or other material); the liquid with which pigment or an existing oil paint is mixed to create or modify the paint, or an expressive art form.
