Well, it's never actually been stated that ice magic is limited to snow and ice. Elsa's magic is limited to these things, but Ingrid's powers are far more advanced. We've seen her use teleportation and levitation, trigger the spell of shattered sight, release Sidney from the mirror (off-screen) and cast the protection spell on the town (also off-screen). Personally, I always thought this magic was part of Ingrid's ice powers, and not witchcraft. Also, when Emma touches the barrier in "Heroes and Villains", I think it looks kind of "frosty" (see this pic).

However, I admit that this may be a tricky one, so if you want to start a discussion about it, feel free to do it. Perhaps we should hear what other people think.
