Is there anything on the surface of the earth that lava can't melt?

Hi Ben, Robby, and John:
Sure there things that lava can't melt. For example, stainless steel,
concrete, already-cooled lava. The temperature of flowing basalt is
usually around 1170 degrees C or less. Anything that you find that has a
melting point above that will be able to withstand melting by lava. I'm
sure there are many more examples than I have given you.
