Hi. Hope I have this in the correct forum.

Is there a relationship between melting / flash point?  More specifically, will the substance melting point effectively be lowered if the substance has a lower flash point than its melting point? 
For example: flash point: 175C, melting point 225C.

Will the substance appear to melt between the two figures?? ~200C

This was communicated to me as fact, and I didnt believe.

Many thanks

Even independently from the substance's behaviour, I don't grasp the logic of a melting point below the melting point.

As for materials: most have their flash point between the melting and boiling point, but there are exceptions. For instance hexamine (hexamethylene tetramine) catches fire before melting. Useful in a stove, to keep the fire contained.
