Crayons are made up of pigment and paraffin wax. They are mixed together and heated to 190 degrees Fahrenheit until a liquid is formed. The liquid is then poured into a preheated crayon-shaped mold. A single mold can make 1,200 crayons at one time The mold is then cooled with water (55 F). Hydraulic pressure is used to eject the crayons from the mold. The crayons are then manually quality checked for imperfections and inspected for broken tips. The excess wax from the mold and any rejected crayons are recycled to be re-melted. 2.4 to 6.4 million crayons can be made in a day! A non-toxic cornstarch and water mixture is used for the glue that holds the label on the Crayola crayon. The crayon is wrapped twice to give it strength. Bare crayons are fed from one hopper while labels are fed from a separate hopper. Glue is added to the glue pot then the label machine is started. The glue transfers to a slot in a drum that a crayon goes into. The label is then fed onto the drum where a roller presses the label against the glue. The label is then tucked and wrapped around the crayon twice. The labels are in 11 languages and 18 different colors. Crayons are packed in boxes of various sizes from 2 - 96 crayons per box.
