Oil Painting
- What Is It?
Oil painting
is done on surfaces with pigments that are ground and mixed into a medium
of oil — especially in early modern Europe, linseed oil. Other
oils occasionally used include poppyseed oil, walnut oil, and safflower
oil. These oils give various properties to the oil paint, such as less
yellowing or different drying times. Certain differences are also visible
in the sheen of the paints depending on the oil. Painters often use
different oils in the same painting depending on specific pigments and
effects desired. The paints themselves also develop a particular feel
depending on the mediums. A basic rule of oil paint application is 'fat
over lean.' This means that each additional layer of paint should be
a bit oilier than the layer below. Traditional oil painting techniques
often begin with paint mixed with turpentine. As a painting gets additional
layers, the paint must get oilier (leaner to fatter) or the final painting
will crack and peel. There are many other painting mediums that can
by used in oil painting, including cold wax, resins, and varnishes.
These additional mediums can aid the painter in adjusting the translucency
of the paint, the sheen of the paint, the density or 'body' of the paint,
and the ability of the paint to hold or conceal the brushstroke. These
variable are closely related to the expressive capacity of oil paint.
When looking at original oil paintings, the various traits of oil paint
allow one to sense the choices the artist made as they applied the paint.
For the viewer, the paint is still, but for the artist, the oil paint
is a liquid or semi-liquid and must be moved 'onto' the painting surface.
