Can you melt lava rocks back into lava?
Can you melt lava rocks back into lava? Yes, at least partially. It is important to remember that a rock usually does not have a single melting point. It melts over an interval. Igneous (magmatic) rocks are made of combination of minerals (for example, quartz, olivine, pyroxene, feldspar) that each will melt at a different point.
