I have learned, when doing my pet portraits, that oil paintings have a luster and glow that cannot be matched by other works of art. Place an oil painting next to, for instance, a painting done with something like acrylics, and this will become plain to see. Here are some things you should remember when using oil in paintings.
When creating an oil painting one should increase the amount of oil for each overlapping layer of paint. This is important because the lower layers of paint tend to 'suck' at the high layers of oil. Proper layering will decrease the chances of the oil cracking on the top layers of paint.
The drying time of oil is can be highly variable from one color to another color. Using a color like ivory black, for instance, will result in that particular oil drying slower than other colors. As silly as it sounds, one needs to actually 'watch the paint dry' to get an idea for this.
Linseed oil is a very valuable material if you want your painting to dry evenly. It is especially useful in the underlying layers of oil in your painting. Linseed oil has a tendency to to dry at the same, even rate.
You should know, however, that linseed oil is not good for all colors. It can cause certain lighter types of colors to 'yellow.' So you should avoid the use of linseed oil whenever you are using lighter colors.
You can hurry up the dry time of your creation by mixing in the proper 'ingredients.' Paints having such elements as lead, cobalt and manganese, for instance, will speed up drying time considerably. You can also mix these pigments with other types of colors if you need a particular oil to dry faster.
And here's a funny one that won't occur to many people, if you dry your painting in the dark, a thin sheen of oil may rise to the surface. This will cause your painting to take on a yellowish tint. So you must leave the lights on when the oil in your painting is drying.
There are other things you should be careful of when working with oil, so the beginning artist must do is 9or her) research before starting work. Is your painting wrinkly, yellowed, sticky after a week, or even two, or (horrors) even three? Simply do a little research, and then, like I do with my pet portraits, start work on another painting.
