Can you store Breath in metal without the [Ninth] Heightening? Just put it there without Awakening, just to hide the Breath.
Brandon Sanderson

Can you hide Breath in-- Yes you can hide Breath in things.
Chris King

Metal in particular, without the [Ninth] Heightening could you put it into metal. Without the purpose of Awakening it, just storing it there.
Brandon Sanderson

Oh without the [Ninth] Heightening-- I would say yes you could.
