Again, depends on what theory you subscribe to. If its the broader definition of earth, which I used to exclusively support, then yea all that should be bendable. For the narrower silicon dependent theory, which is starting to grow on me, then things get a bit messy. Chances are, like the vast majority of earthen substances, the crystals bent in Ba Sing Se were rich in silicon, while salt is basically just NaCl. Diamonds tend to lack silicon as well, being pretty much pure carbon. Coal, on the other hand, tends to have a good chunk of silicon in its makeup,</i></div>
<p>I think earthbenders can bend anything made up out of minerals. I get the idea it's more the state of the matter that determines if someone can bend it rather than what atoms it contains. I wonder if waterbenders could bend non-water liquids like mercury too.
