Crayola offers many craft ideas on our sites, including some where crayons are melted. We do have a warning note in these techniques that states care should be exercised when melting Crayola Crayons and that irritating fumes can be released if heated at a high temperature. Our crayons have a melting point between 128-147 degrees Fahrenheit and they will begin to soften at about 105 degrees Fahrenheit. For more information, please visit
