Does lava melt rock? The short answer is that while lava is hot, it’s not hot enough to melt the rocks on the side of or surrounding the volcano.

What rock Cannot be melted by lava? Tungsten(Wolfram) is a great example since it has a melting point above 3000 °C, chromium, niobium molybdenum, rhenium, titanium and tantalum are all good examples that don’t melt below titanium’s minimal temp of 1668 °C…
Would lava melt concrete? Not exactly. Concrete has a melting point at about 1,500 °C (2,700 °F). Even the hottest orange lava only reaches 871°C (1,600 °F). … If the magma were unable to penetrate the concrete, it would explode out of its sides.
Can lava rocks melt 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.
