I think what Dumbledore does in this scene is making the glass shards into glass dust, not sand. Like when it hits the shield it turns into smaller pieces.

Is it possible this spell be a Shield Charm which dissolved the glass shards and transformed them into glass dust? Andre G. Dias (talk) 20:51, April 8, 2014 (Brazil)
