Oiltopigment

Oiltopigment refers to a type of pigment that is formulated for use with oil-based mediums, such as oil paints. These pigments are typically ground into fine particles and then suspended in a drying oil, most commonly linseed oil. The choice of oil and the grinding process significantly influence the pigment's properties, including its color, opacity, transparency, lightfastness, and working consistency.

Historically, pigments were derived from natural sources, including minerals, plants, and animals. For instance, ochres are mineral pigments containing iron oxides, while lapis lazuli provided the vibrant ultramarine blue. As chemical advancements progressed, synthetic pigments became more prevalent, offering a wider range of colors, greater purity, and often improved stability.

The application of oiltopigments in oil painting allows for a rich depth of color and subtle blending capabilities. Artists choose pigments based on their desired effects, considering factors such as permanence, toxicity, and how the pigment interacts with other colors and mediums. The binder, the oil in this case, acts as a vehicle for the pigment and forms a protective film as it dries through oxidation. The quality and particle size of the pigment are crucial for achieving desired chromatic and textural effects on the canvas.
