How Much Can Basalt Melt

Melting Rocks

Can molten rocklava be produced by heating igneous rock to 2021 degrees in a furnace Although this might seem like a simple question there are many variables that determine whether a rock will melt at a given temperature You did not specify C or F but I assume you mean F which would be about 1100 o C The type of rock is important If you were trying to melt Hawaiian basalt lava it would
