Description
A hard wax-based stick usually wrapped in a protective paper, used for drawing. Crayons are often sold in sets of colors, but as an artists' material it is often black. The popular Crayola® brand crayons were introduced in 1903 by Binney & Smith. Marketed for children, these first crayons contained Paraffin wax, Stearic acid, oil, and pigments. Today, many different quality wax crayons are produced for children as well as for artists. The base for the crayons is a wax (such as paraffin, Beeswax, carnauba, or Polyethylene) mixed with a colorant (pigment or dye). Some soft crayons have small amounts of an oil and/or fat (Stearic acid, Tallow) while some hard crayons have a filler (Kaolin, Talc). A few brands produce a water-soluble type crayon that contains an emulsified wax and Polyethylene glycol (Ellis and Yeh 1997).
