From Wax to CrayonBook - 2003
How are crayons made? Clear wax is melted in a factory. Once it's melted, color is added to it, it is poured into crayon-shaped molds, cooled, and wrapped in a paper label. Sorted into sets, the brightly colored crayons are boxed and sent in trucks to stores to be sold to you.
