What should I know about oil painting?
The oil color is a mixture of color (pigment) and oil (medium). Colors are usually mixed by an artist for each particular project. Mixing the pigment with the medium is the basis of successful oil painting. The oil painting includes the application of oil paints in layers on canvas or other surfaces.
commonly used media are linen, walnuts and poppy oil. The media have different qualities. Linen oil oil dries most thickening, so it is often used on the lower layers of oil images. Linseed oil tends to yellow, so it is difficult to use with lighter pigments. The poppy oil is the least yellowing of the media and is also slower to dry. It is often used in white and lighter colors, as in the upper layers of oil paintings. Stronger colors will produce more textures, sometimes revealing brushes. Thinner colors are more transparent to enable the creation of color variations. For this process is essential layering of oil paint.
The primary principle of oil painting is the rule "fat above slim". Top colors, colors mixed with less oil, must be applied under thicker colors, pigments mixed with larger oil. Top colors must go under thicker colors because it dries faster than those with more medium. The lower oil painting layers must contain less oil because they absorb some of the layered color media. Colors with smaller oil dry faster than fat colors. If the upper layers of dry painting in front of the lower layers, the color bursts.
The oil paint does not dry as evaporation like most colors. The oil paint dries oxidation, which is a much slower drying process. For about two weeks, the touch will be dry. It will be sufficiently dry for toinish with a paint for about six to twelve months. The oil painting will not be considered completed until 60 to 80 years.
Because oil colors remain wet for such a long time, it is possible for an artist to change colors and textUry while working on the picture. The whole layer of paint can be removed from the unfinished work with a rag and turpentine or alcohol. Once the color has begun to dry out, the removal of the color may require scratching.
The origin of the oil painting dates back to ancient times. The shields decorated with oil -based paint were considered more resistant than those without.
