When the wax melts, it, rises through the wick and are vapourised during burning and form flames. Charcoal, on the other hand, does not vapourise and so does not produce a flame. Charcoal is a fuel which is used in home and it is combustible substance. The substance which vapourises during burning gives flame. For eg:- wax, petrol, kerosene.
