While trying to make iron oxide (putting two nails on a battery and into a cup of saltwater) as an ingredient to make thermite, I produced a strange chemical in the mix.  It was dark green/blue and sunk to the bottom of the mixture.  Can anyone help me identify it? Thanks.

One of the electrode or part of the immersed conductors was copper? Then the blue/green is Cu(H₂O)₆⁺⁺ and CuCl⁺ (and other complexes of Cu⁺⁺ with Cl^-).

You might try this again using sodium bicarbonate instead of salt with replacement nails of the same type.
