Why do oil paintings have to use colored oil and colored oil? There are many kinds, so pay attention to them.

Because "color oil" is the medium oil of oil painting, it is mainly used to dilute oil painting pigments.

When used in painting, it can increase the gloss of color, control the drying speed of color, and use its fluidity to achieve the required painting effect. There are common color oil with average drying speed, quick-drying oil with faster drying speed and linseed oil with slower color drying, which are used according to different performance processes.

Oils used as color media can be divided into two categories: one is volatile oil, such as turpentine, lavender oil and refined gasoline. Second, drying oil, such as poppy oil, linseed oil, walnut oil, safflower oil and sunflower oil. Different oils have different functions. To master oil painting techniques, we must know how to use color media.

Common color oils:

1 turpentine

Turpentine is a volatile colorless transparent liquid extracted by distillation of turpentine, also known as resin turpentine. In painting, it can be used as a diluent for pigments and toners, and also as a solvent for resins.

High-quality turpentine will not leave residue after rapid volatilization. Domestic painters mostly use medical turpentine, which is available in pharmacies. It is the best diluent for undercoating large color blocks. Venetian turpentine has nothing to do with resin turpentine. This is a very dense amber liquid. When added to oil paints and colored oils, it can produce a firm and gem-like conjunctiva. Therefore, it is often used as a glazing medium.

2. Linseed oil

Linseed oil, also known as linseed oil, is extracted from the seeds of flax plants and is the main medium of oil painting pigments. Cold pressed linseed oil: This is the purest form of linseed oil. Its basic use is as a mixture of oil painting pigments.

3. Walnut oil (walnut oil)

/kloc-this oil was used by European painters before the 0/8th century, and was later replaced by linseed oil. Good fluidity, but slow drying. Contemporary painters use it as a blending agent for classical oil paintings. There are two kinds of walnut oil on the market: cold pressing and cooked cold pressing.

Cold pressed pure raw walnut oil: it is one of the best color oils. You can use this oil and turpentine to make a draft, or you can make your own three-in-one oil or color it directly. Solidified cold-pressed walnut oil: it is made by heating cold-pressed walnut oil without air isolation, which contains lead oxide for self-made toner. Drying speed is faster.

4, safflower oil and poppy oil

Safflower oil: the color lasts well and will not turn yellow with time. It is a high quality oil for producing white and other light-colored pigments. It is mostly used by famous pigment manufacturers to produce white oil painting pigments. Poppy oil: extracted from opium seeds, mainly used to make white and light pigments. Slow drying, weak conjunctiva. Sunlight thickened poppy oil is the best color oil.

5. Emulsion matte toner (matte oil)

Contains cellulose and dammar resin. By adding to the color, the colored layer can produce a matte effect. Alternately used with triple heavy oil, suitable for classical transparent painting. The drying speed is fast.

6. Sanhe color oil

It is a shiny colored oil used for painting or polishing. It is made by mixing 1 part linseed oil, 1 part dama resin varnish and 1-3 parts turpentine. The dryness is moderate.

7, oil painting color paste

Toner paste is a thick medium. It can change the color of opaque oil painting into transparent color, which is most suitable for transparent thin dye painting and has a fast drying speed. If you use it to color and dye, you can draw in different colors immediately.

8. Alkyd resin medium

It belongs to a new material, which may replace the traditional toner. There are many brands abroad, which have obvious advantages: it can speed up the drying time in harmony with the color of oil painting; Can increase transparency; Make the color layer more shiny; Make the color more saturated; The colored layer is also more durable.

9. Mineral alcohol

Mineral alcohol is a by-product of petroleum. As a thinner for oil painting, it has the same function as turpentine. As pure as water, it is the most volatile, but slightly less soluble.
