(not a volcanologist or rock fag) Mafic and Felsic rocks are called rocks...so while you can melt granite and produce a melted pool of some sort of silica based liquid rock, it is simply a transformed rock.
I'm not aware of any rocks having some sort of immutable status.
All that said however, it is an interesting discussion. Upvotes pending.
Glass isnt rock
And gasoline isn't crude oil. Lava is not pure glass.
Lava is man made...and not that hot
And its not from melting rocks its from trannies playing Disneyland games
