I'm no thaumaturge, but I did make up some books for theorizing how aether works. The short of it is that a user's aether is manipulated to mimic the material components of actual elements: magical fire isn't real fire, but it emulates ignition and burning. Similarly, magical ice isn't real ice but looks like frozen water, etc.
Ever since they dropped the Astral/Umbral side of things, I've had no idea what the ACTUAL rules were.
