摘要:
A method for making crayons is provided. The method employs an apparatus which includes a base that houses a heating component, a melt pan disposed to absorb heat from the heating component, a mold, and a cover. The melt pan receives crayon material and contains it as the heating component increases the temperature, causing the crayon material to liquefy. The liquefied crayon material can then be drained by the user of the device, into a mold with crayon-shaped cavities. A timer and a cover prevents access to the melt pan and the mold during particular operating conditions of the apparatus.
