Learn How to Art: What is Oil Paint?

Different types of paint can get confusing. How can you choose between oil paint, acrylic, watercolor, and whatever else might be out there?

I once did a goodbye painting for a coworker. I was leaving the country and wanted to leave a meaningful gift.

Once I gave a coworker a painting I’d done as a goodbye gift. She thanked me and then asked if it was oil.

Definitely not! I thought, thinking of how much of a hassle it would be to do oil paintings in the small room I lived in at the time. How many supplies I’d need to get. How I’d need to paint in a well-ventilated area. How much of a hassle cleaning up would be since I didn’t know where to dispose of toxic material in South Korea. But I limited my response to:

“Oh, no it’s acrylic.”

The complexities of oil paint are like a well-kept secret from people outside of the art world.

I’ve done art my entire life, but I had no idea how oil painting worked until I took a class in college.

Just about everyone has painted with tempera paints in elementary school or acrylic in middle and high school art classes. But all anyone seems to know about oil is that it’s a sophisticated paint used by the greats.

Maybe I now have you wondering,

  • What’s so special about oil painting?
  • What’s the difference between acrylic and oil paint?
  • What even is tempera?
  • Would it be easier to go with watercolor?

This post will be the first in a series on paints. By the end, you’ll understand the difference between acrylic vs. oil, know what tempera is made of, and learn how you can use salt with watercolors.

Today I’ll go into oil painting.

 

Why Use Oil Paint?

Oil paint, as we’ve established, is fancy. The most famous artists in the world have worked extensively in this media: da Vinci, Van Gogh, Vermeer, Manet, Monet, and Rembrandt are just a few artists who excel in oil.

Oil paint has a certain prestige, but when you’re just trying to decide what type of paint to use, that doesn’t matter. Let’s get into what does.

 

So. Much. Color.

Color is the greatest benefit of oil. Oil paints have a high concentration of pigment, which leads to fuller, richer colors than other paints.

Oil paintings also retain their original color. Let me explain. When acrylic paint dries, it usually darkens. A low-grade acrylic paint might change color significantly.

Consistency is Key

Oil paints don’t change color when they dry, and that’s reason enough for many artists to choose oil over acrylic. However, oils do change over time. Ever notice how old, famous paintings tend to have a golden sheen to them?

That’s because the binders in oil paint start to yellow with age. But this is over the course of decades or even centuries.

Lose Yourself in the Process

Oil paintings will often take up more of your time. These paints dry very slowly, so if you want to do any layering with distinct colors, you’ll need to wait. An oil painting can take days or even weeks to dry, depending on the thickness of your paint and humidity levels.

On the plus side, if blending colors is more your style, this is easy to do with oil. Your paints won’t dry out on your palette for days, leaving plenty of time for mixing colors. You can also blend right on the surface of your painting. Just don’t forget to keep that brush clean if you want to keep your original color.

 

Painting Surface

For oil, you need to use a prepared surface, like a canvas that’s bee coated in gesso. Oil paint is corrosive, so you can’t just paint on anything. You can prime the surface of a canvas or board yourself or purchase a pre-primed canvas in an art supplies store.

 

In Addition to Paint, You Need…

While many beginners use student grade acrylics straight from a tube, you shouldn’t do this with oil. Oil paints need a medium, like linseed oil or dammar varnish. Professional painters develop their own preferred mixtures and ratios of paint to medium. There are several “right” ways to mix your paints.

You’ll also need to take extra steps for cleanup.

Being oil based, you can’t simply wash your leftover paints down the drain. You need to use turpentine or mineral spirits to clean your brushes, palette, or any other surface. Use a rag or paper towels dipped in turpentine to clean surfaces.

Since these substances are toxic and flammable you need to dispose of them properly and store them in a safe area.

You should also paint in a well-ventilated area.

Oil paints are a little more costly than any other paint. But they contain a high concentration of pigment, making them stunning. Rest assured that if you decide to learn oil painting, you’ve chosen one of the artsiest of all art media.

  1. Thanks for helping me understand that it is important that the canvass is well prepared when using oil paint. Like you said, using this kind of paint can’t just be done in any surface. I will keep that in mind so that I will be able to create the design that I have been dreaming of. As of now, I am currently looking for painting workshops because I still have a lot to learn. I just started being interested with this activity due to being influenced by the videos I see online.

    • That’s wonderful! I hope you find some workshops you enjoy. The beginning is always difficult, but don’t be discouraged and keep trying!
