How are those shards obsidian? Obsidian is a black glass-like structure. Those are transparent crystals.

Also, I mis-typed earlier. I didn't mean to write that the glyphs appeared under Glynda's feet, I meant the glyphs appear around Cinder's body when she uses that huge burst of fire to incinerate all of Glynda's projectiles surrounding the airship.
