Difference and history of oil and acrylic paints

Acrylic paint was first made in the 1950’s and as it being a fast drying medium it became wildly popular. It uses synthetic resin as a binder instead of oil – the main reason for its quick drying time. Depending on how it is used it can look like watercolor, oil paint or like its own unique acrylic self. The artist, David Hockney was an early champion of acrylic paint using it shortly after it was introduced to the world.

Unlike acrylic paint oil paint uses oil (commonly linseed oil) to bind pigments and therefore is a slow drying medium. Oils are definitely the historical medium out of the two dating back to at least 12th century Europe where they were first used for simple decoration. It was not until the 15th century that oil paints were widely adopted. The Flemish painter Jan van Eyck did not invent oil painting but created novel effects with the medium that elevated painting to an entirely new level.

Oil Painting vs Acrylic color and drying time

In general oil paints tend to have richer color than acrylics, though oil paints do show that they fade over hundreds of years. Acrylic paints have not been around long enough for us to truly know, but it appears that acrylic paintings do not fade. Acrylics also might darken slightly as it dries while oil paint does not (in fact it sometimes does the opposite and lightens a little)

The biggest difference between acrylic paint and oil is drying time. Acrylic paint dries in under an hour if not minutes. Thus you have to be on top of it when it comes to washing your brushes right away and cleaning your palette. If you do not clean your brushes right after finishing your painting session – the paint will dry on your brushes and they will be ruined! Oil on the other hand dries within days (at the quickest) therefore there is not as much urgency required when it comes to brush cleaning!

Different properties when considering Oil Painting vs Acrylic

Texture of the paints

Oil paint has more of a smooth texture to it and appears more ‘luminous’ than acrylic. When comparing the two acrylic has a rough and porous texture to it and falls a little flat when comparing it to the ‘vibrant’ quality of oil. Acrylic paint shrinks sometimes while drying so brush effects are sometimes lost. The water that is lodged in it when applying the paint evaporates during drying time causing the shrinkage.

Weight of the paint

Oil paint is generally heavier than acrylic paint. The weight of oil paints vary as to which color you are referring to (as some contain heavy metals while others do not and are therefore lighter). Acrylic paints are light and for the most part are uniform in weight regardless of color.

That said, stiffer brushes (such as bristle) do not work as well on Acrylic paints because it is so light. the brush would broom the paint up instead of laying it across the canvas.

Solvent/ Water

One wonderfully easy thing about Acrylic paint is that it uses water to be diluted instead of solvent. This makes acrylic paint much easier to clean up when compared to oil paints and is perhaps a big reason why many choose acrylic paint over oil paints.

For clean up with oils you can use vegetable oil/ soap (olive oil soap works great actually!). Just be sure to never use solvents on your own hands/ arms – it is very bad for you!

Toxicity

It is not true that oil paint is more toxic than acrylic paint. It is the pigment that makes a paint toxic or not, both acrylic and oil paints contain the same pigments (or at least all good quality artist pigments are the same). The binding medium for oil paints – linseed oil – is even edible. The same cannot be said of acrylic paints which use synthetic resin binders and chemicals to make balanced paint.

As you can see oil and acrylic paints vary greatly in their properties. It is up to you and what your vision is for your work to decide which medium will serve that vision the best.
