Types Of Crayons And Its Manufacturing Methods | Forum

Crayons are made of compressed chalk, pigment powder, and adhesive. The paintings created with these crayons are called colored crayon paintings. The traditional binding material is astragalus gum. When the binding material is linseed oil, the crayon is called oil pastel. Colored crayons are used for painting on brown paper, cardboard, or specially prepared canvas. Colored crayon drawings are easily damaged because they blur when touched. Color fixatives can protect the picture, but are not advisable because they can darken the color of the painting. The best way to protect colored crayon paintings is to frame them with glass.

With careful protection, colored crayon paintings stay fresh and colorful for longer than oil or watercolor paintings. They do not lose their color as oil paintings do, nor do they become damp as watercolors do. The beauty of colored crayon painting lies mainly in its soft velvety surface, which gives the painting a depth of color harmony and atmosphere that cannot be achieved by other methods. Colored crayons are particularly suitable for painting portraits, still lifes, and certain landscapes.
