Art paints are made on the basis of pigments and binders plus special fillers. Pigments can be mineral (inorganic) and organic. They, in different ways, determine the value of art paints and affect their color, intensity, and light fastness.
According to composition, art paints are divided into several types:
Types and their features
Art paints are classified according to the binder type:
- Watercolor paints. Hey belong to the glue paints group. The masters of the Renaissance worked with them, creating sketches for frescoes and easel works. The main advantage is transparency, due to which the pictures look airy, light and bright. Watercolor paints are easy to load onto a brush and to put on paper. But the watercolor technique is one of the most difficult.
- Acrylic. On the basis, there is a polymeric substance that makes the coating strong and dense. Modern acrylic paints are simple, reliable, durable. They are easily put on paper and don’t require special preparation. The color spectrum is extensive and diverse. Acrylic paints are liquid or thick. They are suitable for working on textured surfaces. In addition, they dry quickly, don’t burn out, don’t rinse and don’t crack even on dynamic bases.
- Gouache. The gouache is an easy-to-use paint, suitable for any job and easily combined with other tools. The main difficulty in the work is reaching the necessary shade. The velvety texture is a special feature. Most gouache paints resemble opaque watercolor paints, but it requires different techniques to work with. The paints are bright and water-soluble.
- Oil. This is the main tool in painting since ancient times. The oil paints are suitable for realistic, vivid, bright pictures. You can work with them calmly and for a long time. The coating depends on the application technique and the layer thickness. Oil paints require special working skills, but allow implementing almost any technique. They are easily mixed. Also, they have an intense color and a thick consistency.
- Tempera. This is an excellent tool for painting, decor and design. It is suitable for work on different surfaces and with different techniques. Tempera colors dry quickly and retain their original quality for a long time. But sometimes they can lose brightness over time. Even thick layers remain durable and reliable. You can draw with the tempera on a paper, a canvas, a wood, a concrete, a glass, a plaster, etc.
What's the difference between the art paints?
Depending on the manufacturer, type, composition, and purposes, paints series differ in some properties:
- Pigment concentration. Concentrated paints last much longer.
- Variety of palettes. They are sold individually or in sets of different sizes and contents.
- Light fastness and pigment stability in general.
- Assortment. In one series there can be usual opaque, translucent and transparent paints.
There are also different kinds of packing:
- Cuvette (only for dry watercolors);
- Tubes (liquid watercolors, oil, tempera, acrylic);
- Banks (acrylic, sketch oil);
- Aerosol cans (acrylic).
Signs of poor-quality paint
There are several basic criteria that indicate the low quality of paints:
- Foreign impurities and particles in the composition.
- The paint lays on the surface unevenly. Strips, spots or stains are formed.
- The colors in one series don’t mix well with each other. The color of the pigment changes.
- The consistency is too thin or too thick.
- Paint dissipation during operation.
- Cracking a dried out picture.
Professional art paints are well-covering. They are easy loading onto the brush and are perfectly mixed. It’s easy and pleasant to work with. Also, high-quality paints are sparingly consumed and don’t crack even when the canvas is twisted.
