Crayons are available in a range of prices, and are easy to work with. They are less messy than most paints and markers, blunt (removing the risk of sharp points present when using a pencil or pen), typically non-toxic, and available in a wide variety of colors. These characteristics make them particularly good instruments for teaching small children to draw in addition to being used widely by student and professional artists.

Composition

In the modern English-speaking world, the term crayon is commonly associated with the standard wax crayon, such as those widely available for use by children. Such crayons are usually approximately 3.5 inches (89 mm) in length and made mostly of paraffin wax. Paraffin wax is heated and cooled to achieve the correct temperature, at which a usable wax substance can be dyed, manufactured and then shipped for use around the world. Paraffin waxes are used for cosmetics, candles, for the preparation of printing ink, fruit preserving, in the pharmaceutical industry, for lubricating purposes, and for manufacturing crayons.

Colin Snedeker, a chemist for Binney & Smith (the then-parent company of Crayola), developed the first washable crayons in response to consumer complaints regarding stained fabrics and walls. A patent for the washable solid marking composition utilized in the washable crayons was awarded to Snedeker in 1990.
