What Is the difference between Chalk and Pastel?
Chalk is a term used by many people as a synonym for pastel. Chalks contain a great deal of binders, fillers and little pure pigment. Blackboard chalk is a good example. Chalks tend to be brittle and hard. Pastels are made from a high percentage of pigment and a small amount of binder. Artists pigments are expensive so a quality pastel is of a much higher expense and quality.
