[Star Wars] If I was a jedi and I stood on the side of a mountain with my lightsaber in the ground all day, churing it, could I make artificial lava pools?

Not very efficiently. Lightsabers are designed to contain as much heat as possible within the confines of the blade, as evidenced by the fact that you can cleanly vaporize the flesh and bone between someone’s hand and arm, without creating a horrific blood steam explosion (ooc: wonderful band name right there) and really stinking up the cantina. This means that heat can only be transferred from the blade into material by conduction and convection within the material itself. A certain Master Qui-Gon Jinn reportedly tried to slice through a durasteel bulkhead, and had much difficulty because the durasteel was re-solidifying nearly as fast as he could cut through. Durasteel is wonderful protection from blaster fire, because it is so good at conducting heat and spreading it evenly throughout its structure. Rock, of any variety, is far worse at conducting heat energy. Therefore, whatever amount of rock you manage to melt will probably just stay in one place without transferring much heat to the surrounding material, leaving you with a lightsaber-blade-shaped pool of lava. Worse still, if there are any gas pockets or hydrates in the rock you’re melting, you’d have a lightsaber-blade-shaped pool of lava spitting steam and bits of molten rock in your face at high velocities. Happy stirring!
