Question: How are crayons made and how did they get all the colors!?
Best Answer - Chosen by Asker:

The two basic ingredients for a crayon are:

* Pigment
* Paraffin wax, stored in heated 17,000 gallon tanks

The mixture is heated until it melts into a liquid!. Crayons melt at 105 degrees Fahrenheit (40 degrees Celsius)!. The mixture is heated to 190 F (82 C)!. The liquid is poured into a preheated mold full of hundreds of crayon-shaped holes!. Cool water (55 F, 13 C) is used to cool the mold, allowing the crayon to be made in 3 to 9 minutes!. A single mold makes 1,200 crayons at a time, weighing a total of about 40 pounds!. The operator uses hydraulic pressure to eject the crayons from the mold!. Earlier mold designs used a hand crank to push up the crayons!. The just-molded 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!. More than 120 crayon colors are possible!.Www@QuestionHome@Com
