Tips
On Oil Painting

To
show subtle changes or shifts in color do not thoroughly
mix the oil colors on your palette. It is a better practice to mute
the chroma on the palette, then apply the paint to the canvas and
mix in the adjacent colors. For example when painting trees it is
a good practice to show variegated greens resulting from intermixing
colors such as lemon yellow, yellow ochre, and burnt sienna. Some
of these colors intermixed should show in a given area.

Painting
with acrylics and oils - In Oil painting it is a traditional
technique to paint an underpainting or a rough sketch on the canvas
before finalizing your painting. Oils also take a considerable time
to dry, especially if the paint is thick or contain a large amount
of oily medium. This can be from weeks to months, depending on the
amount of the humidity in the atmosphere. The usual way to painting
an oil begins with the underpainting where the essential ideas and
designs are worked out in rough. Underpainting also has the additional
advantage of being visible through other glazed layers on top of
it and thereby influencing the finished painting. By using an acrylic
layer as an underpainting one has all the advantage of an oil underpainting
while also saving time.

Avoid
using linseed oil as a medium in whites and blues as it
has a marked tendency to yellow, which is most notable with light
colors. Poppy oil is recommended for light colors as it has the
least tendency to yellow (although it does dry slower).

The
Importance of Oils - The type of processing that oils undergo
determines their characteristics and how they interact with paint.
Stand oil is made by heating oil without contact with air. This
causes a molecular change--polymerization--that gives the oil a
syrupy quality. Stand linseed oil is particularly useful in painting
mediums. Thinned with turpentine or mineral spirits, it increases
the flow properties of oil paint. The resulting paint film will
resist yellowing, be tough and elastic, and retain its flexibility
as it ages. Because it is slow to dry, stand linseed oil is often
combined with damar varnish and a solvent to promote drying.

Oiling
out is the application of an oil medium to a painting which
has sunk (become dull), or lost its oil to the layer underneath.
The most common causes for this are an over- absorbent, cheap ground
or the use of too much solvent and insufficient or no medium. When
the color is dry, Artists Painting Medium should be sparingly rubbed
into any sunken areas with a clean cloth. Wipe off any residue and
leave to dry for a day or two. If smaller, dull areas remain, repeat
the process until the painting has regained an even sheen. Varnishes
should not be used for the purpose of recovering the lustre of a
dead painting. For a faster drying oiling out medium, use Thickened
Linseed Oil diluted with 50% white spirit (mineral spirits).

Drying
oil paints quickly - You can add driers like cobalt and
lead--something will be available at whatever art supply store there
is near you. If you are adding details on top of a color you could
also try using a thick gooey stand oil. If the longevity of the
piece is an issue, why not use hair driers? By pushing the piece
to dry so quickly you will cause it to die quickly as well. I'm
not fond of using acrylics but next time try those with some acrylic
mediums, and thinning with water. I've been seeing acrylic paintings
lately where the painter made better use of the acrylic paint than
a lot of oil painters make of oils, in that rich, vivid colors were
built up of several transparent layers. BUT IF YOU WANT YOUR
PIECE TO LAST DON"T FORCE IT TO DRY! It will crack up--not
immediately, but you will probably outlive it.

If
you are a beginning to intermediate painter, purchase the
most economical tubes available. Your first couple of years painting
you should concentrate on producing a lot of paintings. The more
you paint, the faster you will learn. Do not expect to create masterpieces,
just enjoy the process. Art quality comes after art quantity. In
other words, PAINT, PAINT, PAINT!

Alkyd Ivory Black and Titanium White - These oil-modified
synthetic resin colors are fast drying, which is an aid when you're
on a deadline. Alkyd paints can be purchased in a full line of colors
if you like their properties. I primarily use the white combined
with my other traditional linseed oil colors. When mixed with traditional
oils, they should be used throughout the painting in a fat-over-lean
approach by increasing the addition of resin (in the form of an
alkyd resin medium, like liquin, or other traditional linseed based
mediums). The paint film produced is more flexible than a normal
linseed oil paint layer, which may reduce cracking when painting
indirectly. Alkyd white therefore has the benefits of greater flexibility,
even than lead white, and has the opacity of titanium. Both features
of this paint should make it age well. Since white is the largest
part of any painting, the one you choose is an important element
in the structure and stability of your work of art. This has become
my primary white for everyday studio painting. But one should be
cautious when using it. I have found that overexposure to its fumes
causes extreme headaches and dizziness, so ventilate your studio
properly.
