The four basic types of dust are apparently fire, ice, lightning, and wind. So the fire, ice, and lightning we've seen so far have not been combined dust.

Meanwhile, we've seen Blake use some kind of rock dust. There apparently exists "gravity" dust, as Monty has mentioned "gravity rounds" being a type of ammunition that Ruby uses. So, it can be assumed that Glynda regularly uses gravity dust for telekinesis.
