Crayon

A crayon (or wax pastel) is a stick of pigmented wax used for writing or drawing. Wax crayons differ from pastels, in which the pigment is mixed with a dry binder such as gum arabic, and from oil pastels, where the binder is a mixture of wax and oil.

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.

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.

The history of the crayon is not entirely clear. The French word crayon, originally meaning "chalk pencil", dates to around the 16th century, and is derived from the word craie (chalk), which comes from the Latin word creta (Earth). The meaning later changed to simply "pencil", which it still means in modern French.

The notion to combine a form of wax with pigment goes back thousands of years. Encaustic painting is a technique that uses hot beeswax combined with colored pigment to bind color into stone. A heat source was then used to "burn in" and fix the image in place. Pliny the Elder, a Roman scholar, was thought to describe the first techniques of wax crayon drawings.

This method, employed by the Egyptians, Romans, Greeks, and indigenous people in the Philippines, is still used today. However, the process was not used to make crayons into a form intended to be held and colored with and was therefore ineffective for use in a classroom or as crafts for children.

Contemporary crayons are purported to have originated in Europe, where some of the first cylinder shaped crayons were made with charcoal and oil. Pastels are an art medium sharing roots with the modern crayon and date back to Leonardo da Vinci in 1495. Conté crayons, out of Paris, are a hybrid between a pastel and a conventional crayon, used since the late 1790s as a drawing crayon for artists. Later, various hues of powdered pigment eventually replaced the primary charcoal ingredient found in most early 19th century products. References to crayons in literature appear as early as 1813 in Jane Austen's Pride and Prejudice. French lithographer Joseph Lemercier [fr] was also one of the inventors of the modern crayon. Through his Paris business circa 1828, he produced a variety of crayon and color related products. But even as those in Europe were discovering that substituting wax for the oil strengthened the crayon, various efforts in the United States were also developing.
