Fixative (drawing) in the context of "Egg white"

Oil pastel is a type of pastel (an art medium that consists of powdered pigment and a binder) that uses mixture of non-drying oil and wax as binder. It differs from other pastels which are made with a gum or methyl cellulose binder, and from wax crayons which are made without oil. The surface of an oil pastel painting is less powdery than one made from other pastels, but more difficult to protect with a fixative. The colors of oil pastels are highly saturated and bright. They can be blended easily but they can break easily too.

Artists' charcoal is charcoal used as a dry art medium. Both compressed charcoal (held together by a gum or wax binder) and charcoal sticks (wooden sticks burned in a kiln without air) are used. The marks it leaves behind on paper are much less permanent than with other media such as graphite, and so lines can easily be erased and blended. Charcoal can produce lines that are very light or intensely black. The dry medium can be applied to almost any surface from smooth to very coarse. Fixatives are used with charcoal drawings to solidify the position to prevent erasing or rubbing off of charcoal dusts.

The method used to create artists' charcoal is similar to that employed in other fields, such as producing gunpowder and cooking fuel. The type of wood material and preparation method allow a variety of charcoal types and textures to be produced.
