Pigment is the material directly reflecting the effect of the work in the painting material, which is made by adding oil to pigment powder and mixing and grinding with glue. Most of the products sold in the market are tubular or self-made.
Oil painting pigment is a kind of substance substance formed by mixing and grinding of mineral, plant, animal and chemical color powder and blending agent flax oil or walnut oil. Its characteristic is that it can dye to other materials or adhere to a certain material to form a certain paint layer. This paint layer has a certain plasticity. It can form all kinds of shape marks and texture that artists want to achieve according to the use of tools.
The hues of oil paints are determined by the hue of the toner. Oil can make the hue of the toner darker and more saturated. Oil painting pigments play an important role in the family of painting pigments. The earliest oil painting pigments were born in the early Renaissance, usually by the painter himself or his assistant according to the needs of the direct grinding and preparation, and then gradually there is a special custom-made paint workshop, after the 17th century, the situation of the painter’s own hand-made paint has been increasingly reduced.
In the 18th century, oil paintings were sold in bags made of animal bladder. The mouth was tied tightly with thread. When using them, an eye was pricked with a needle to extrude the paint. This may be the prototype of lead tin tube paint later. In the 1830s, there were oil paints installed in metal and glass injection tubes, but this inconvenient invention was soon replaced by more scientific lead tin tube pigments before it was popularized.
