Details On Acrylic And Oil Painting
Oil paint is a slow-drying paint that contains particles of pigment suspended in a drying oil. Acrylic paint is a fast-drying paint that has pigment suspended in an acrylic polymer emulsion. Even though acrylic paints can be diluted with water, once they are dry, the resulting product is water resistant. A finished acrylic painting can have the appearance of a watercolor, an oil painting, or some other unique look, depending on the percentage of dilution with water, gels, or pastes.
The reason oil paint is called "oil based" and acrylic paint is called "water based," is because the main binding ingredient of oil paint is linseed oil and that of acrylic paint is water.
Acrylic paint and oil paint require different lengths of time to dry. Oils take relatively more time to dry, typically several weeks, depending on the ingredients used. This is because oils do not undergo the same process of evaporation that water does when exposed to air. Rather, oil paint oxidizes into a dry solid. This property causes oil paint to dry very slowly, giving the artist time to blend colors and adjust the final product.
Acrylic paint is a favorite of artists who want speedy results, as only a few hours are needed for it to dry. To suit a wider range of artists, Golden Artist Colors came out with a slower drying version of acrylic paint in 2008 that has the qualities of oil paint combined with the shorter drying time of acrylic paint; this paint remains wet for few more hours on the canvas under normal conditions.
When we use oil paint, we need a solvent such as turpentine to thin the paint and clean up the work space, which has its disadvantages because turpentine has toxic qualities. An additional step that is required is that the canvas must be thoroughly primed before being painted on, and afterward a removable protective layer of varnish should be applied to the finished product.
The appearance of the paint can become yellow and brittle over time, and, to avoid cracking, the principle of "fat over lean" must be adhered to; each layer of paint that is applied must have a higher oil to pigment ratio.
Acrylic is typically more versatile in nature to use for the average artist, although because of its faster drying time, the painter is not able to blend colors or use the wet-in-wet technique available to oil paint. Retarders can be added to acrylic paint to slow the drying process, allowing water to be added to make the paint more workable.
