Pastel Painting

Pastel painting is defined as a fine art medium in the form of a stick. It contains pure powdered dye and a binder. The coloring used in pastels includes all colored art media such as oil paints, binder etc. The binder is of a neutral shade and low diffusion.

The accurate composition and uniqueness of an individual stick which is used in pastel painting depends on the nature of pastel and the amount of binder used. It may vary by individual manufacturer. Gum Arabic and gum tragacanth are the binders which have been used traditionally for dry pastels. The binder Methyl cellulose was introduced in the twentieth century. It contains often a chalk or gypsum component in it. 

The dry pastel media may be sub divided as follows:

  • Soft pastels: This is the most extensively used form of pastel. The sticks used for soft pastels have a superior portion of pigment and less binder, ensuing in brighter colors.
  • Hard pastels: The hard pastels have an elevated piece of binder and less pigment, producing a sharp drawing objects that is useful for fine details.
  • Pastel pencils: The pastel pencils contain a pastel lead. They are used to add fine details of drawing.
Different approach to manufacture

  • Oil pastels : These oil pastels have a soft, buttery uniformity and strong colors. They do not need glue and are slightly more difficult to blend than soft pastel.
  • Water-soluble pastels : These are parallel to soft pastels, but have a water-soluble component in it such as glycol. This permits the colors to be thinned out using water wash.
