The basic ingredients contained in Crayola Crayons are paraffin wax and color pigment. The ingredients are the same for all Crayola Crayon colors, with some modifications in special effects crayons. We manufacture almost 3 billion crayons each year. The paraffin wax is melted and mixed together with pre-measured amounts of color pigments. We purchase the powder pigments and either use individual colors or mix the pigments to produce the many colors of Crayola Crayons. The hot wax mixture is poured into molding machines. In about four to seven minutes, the crayons cool and become solid. The crayon manufacturing process can be viewed by clicking here.
There is a book available titled "Crayons From Start To Finish". The book offers a behind-the-scenes look at the whole manufacturing process. To obtain this book, please visit your local library. As a further reference, the ISBN is 1-56711-390-7 and the author of the book is Samuel G. Woods.
