Some minerals won't glow at all. WebDuring the rock cycle, the most volatile components tend towards the felsic rocks. Water and fluxes generally reduce the melting point. And felsic rocks usually have alkalis compared to Fe/Mg in mafic rocks. Alkalis are more reactive and volatile. If you partially melt mafic rocks, the most reactive and volatile components are in the first melt.
