öljyvärein

Öljyvärein is a Finnish term that translates to "oil paints" in English. It refers to a type of pigment suspended in a drying oil, typically linseed oil, but sometimes poppyseed oil, walnut oil, or safflower oil. Oil paints are known for their rich color, slow drying time, and versatility, allowing for a wide range of techniques from subtle glazes to thick impasto applications.

The history of oil painting dates back centuries, with its widespread use becoming prominent during the Renaissance. The slow drying time of oil paints allows artists to blend colors smoothly, create soft transitions, and rework areas of the painting over extended periods. This makes them ideal for achieving realism and depth. The pigments used in oil paints can be made from various sources, including minerals, plants, and synthetic compounds, offering a vast spectrum of colors.

When oil paints dry, they undergo a chemical process called oxidation, which polymerizes the oil and binds the pigment particles together, forming a durable film. This drying process can take anywhere from a few days to several months, depending on the thickness of the paint application, the type of oil used, and environmental conditions. Solvents such as turpentine or mineral spirits are commonly used to thin oil paints and clean brushes. Varnishes are often applied to finished oil paintings to protect the surface and enhance the colors.
