How does a crayon melt?

Answer:
The large molecules of paraffin (and there are several different ones) "cling" to each other electromagnetically, similar to butter. They all form a solid at temperatures below about 117°F or so. Above that temperature to about 147°F, the paraffin molecules "unhook" from each other and become a liquid during the melting process.

Note that there is a temperature range for the melting point of paraffin because of the different molecules in this substance. The pigments don't really affect the melting point under normal circumstances. If the crayon is absorbing radiant heat to melt, however, the darker colors, particularly black, will facilitate that process. A link can be found below for more information.
