subject: Pet Portraits Painter Learns The Subtle Tricks Of Oil Painting [print this page] I have learned, from painting my pet portraits, that oil paintings have a luster and glow that cannot be matched by other works of art. Hang an oil painting next to, for instance, an acrylic painting, and this will become plain to see. Here are some tips you should consider when using oil in paintings.
When creating an oil painting one should increase the proportion of oil for each successive layer of paint that one lays down. The reason this is important is because the earlier layers of paint tend to leech the oil. Proper layering will decrease this leeching effect and will decrease the chances of the oil cracking on the top layers.
The drying time of oil is can change greatly from one color to another color. Using a color like ivory black, to use one example, will result in that particular oil drying slower than other oil colors. As silly as it sounds, one needs to actually 'watch the paint dry' a few times to understand how this effects your work.
Linseed oil is very valuable if you want your painting to dry evenly. It is especially useful in the bottom layers of oil in your work. Linseed oil has a tendency to to dry at an even pace.
You should know, however, that linseed oil is good for all oils. It can cause certain types of paint to turn a bit 'yellow.' So you should stay away from linseed oil if you are using lighter shades of colors.
You can speed up the drying time of your painting by mixing in the proper 'ingredients.' Pigments containing such elements as lead, cobalt and manganese, for instance, will speed up drying time considerably. You can also mix these pigments with various colors if you want a particular oil to dry faster.
And here's a funny one that not many people think of, if you dry your painting in the dark, a thin sheen of oil may rise to the surface. This will cause your painting to turn yellow. So you must leave the lights on when 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.
