Crayons are primarily made from paraffin wax, which is a byproduct of oil refining, along with added pigments for color. The process transforms oil derivatives into a common art supply.
Crayon Manufacturing Process
Here's how crayons are made, incorporating the provided reference steps:
- Wax Arrival: Hot paraffin wax, derived from oil, arrives at the crayon-making plant. This is the main component of the crayon.
- Mixing: Heated machines combine the molten paraffin wax with pigments, which give the crayons their different colors.
- Molding: The hot, colored, waxy liquid mixture is then poured into crayon molds. These molds have the characteristic shape of crayons.
- Cooling: Cold water circulates through tubes in the molds. This cools the wax down and hardens it into solid crayons.
Oil to Crayon: The Transformation
The core of the crayon-making process is the use of paraffin wax, derived from crude oil. Here’s a breakdown:
- Crude Oil Refining: Crude oil is processed into various products, including paraffin wax, a byproduct.
- Paraffin Wax Extraction: Paraffin wax is separated and purified during the oil refining process.
- Crayon Formulation: This wax is then the main ingredient in crayons, mixed with colorants.

| Step | Description |
|---|---|
| 1. Wax Arrival | Hot paraffin wax arrives at the factory. |
| 2. Mixing | Wax is mixed with pigments using heated machines. |
| 3. Molding | The hot liquid is poured into molds. |
| 4. Cooling | Cold water cools the wax in the molds to form solid crayons. |
This simple yet precise process takes a byproduct of the oil industry and transforms it into a beloved art supply.
