Then consider how many earth benders have any understanding if geo-physics, the four layers of a life sustaining planet, or that minerals can be more than rock, sand, dirt or crystal.
On that note, the only generally speaking the only liquid to solid phase changes most people have seen is water crystalizing into ice or melted metal cooling into a solid (something not achieved through bending) and occasionally lava into earth.
It took a blind girl with seismic abilities to recognize metal as a refined form of earth even though metal objects were common place to everyone around the world.
The key to bending lava is understanding it at its basic principal
