I'm pretty sure the shards she shot at Ruby weren't the glass that they talked about. Those might have been ice.

The glass they talked about was the black glass swords that Cinder made. Obsidian is black glass that forms after a volcanic eruption, so my theory is that orange Dust is lava Dust, and Cinder used her Aura to choose what shape the lava Dust would flow into, then had it quickly cool into sword-shaped chunks of obsidian. Obsidian is actually very practical for cutting because it has a smoother edge than even the finest steel scalpel.
