       Chemical omlet

       haha this one is pretty interesting. We all know what will
       happen if you sprinkle some sulfur in molten potassium nitrate.
       A couple of weeks back, I tested the same with all nitrates I
       have. Each nitrate had reacted almost differently with sulfur.
       Usually, if you heat something with sulfur, sulfur sticks to the
       walls of the test tube and it is bit difficult to scrub it off.
       Normally, I wash it off with warm sodium hydroxide solution and
       it will come off like flakes. But, I did notice a peculiar thing
       when I heated with Aluminium nitrate. Yes, it became a one
       collective mass like an egg omlet. Wow! look at this pic :-)

       Interesting...did you try further heating of the 'omlet'...?

       oh yes, well it is may be because of the formation of Aluminium
       oxide. Unlike alkali & alkaline earth metal nitrates, Aluminium
       nitrate oxidizes sulfur to sulfur dioxide and itself reduced to
       Nitrogen dioxide and Aluminium oxide. The same with some
       transition metal nitrates such as Ferric nitrate, copper nitrate
       etc.... So, by using this method, you can prepare cupric oxide
       quite easily.
       Thanks,
       Shiva

       most likely a smuggy mix of unreacted sulfur and Al2O3

       Of course, Aluminium oxide is very fine and free flowing and
       that may make the sulfur non sticky.
