Cryokinesis is the power that can cause things to become brittle enough for her to break, such as an electronic lock. She can freeze an entire person and put them into stasis lock or render them immobile by freezing only their wet suits. Mixed with Cleo’s power, Emma can create ice sculptures or ice-orbs, but it would eventually melt or shatter. At first, it implies that she could only freeze things with water over it. But several times in season one, Emma was able to freeze, cool, and lock objects with her powers without the aids of water. This could imply that she can freeze the small water molecules around those dry objects. When in the moon pool it was upgraded from Cryokinesis.
