^while i agree that there must be other ways to manipulate dust, you gotta take into account that cinder already had half of the fall maiden's powers at the time, i honestly think she used maiden powah for the heat/fire, and her dress simply had a particular kind of material that could be made into super-hard glass, maybe something similar to silicon carbide.

also you gotta take into account that when they showed the fight with amber she already could make sharp glass shards from molten sand, she just needed an external heat source, so i'm guessing cinder's semblance is glass manipulation.

just sayin'
