I'm looking for characteristics of different states of material, or
at least some of them, which are "most known", or "visual" to
people.

Exactly this I would to know.  Do you have ideas which data should
be stored in array?  I can think only about density, which can
determine, can object sink or surface, and, with big different of
densities, one object could broke another object.  Also color of
different state, which people can see when look at object.  Anybody
know other "visual" characteristics?

Thanks.
