There is only one type of sculpey that dries on its own: Model Air. If you're using just regular sculpey, technically all polymer clay will go 'hard' if left on its own at room temperature, but it won't actually 'dry out' on its own. By default, sculpey is a pretty tough material to work with and needs to be conditioned (softened and warmed up) to work with and leaving it alone will just return it to its default state.
Basically, if you're using just regular sculpey it'll never actually harden up. If it's not baked, it will eventually break apart as dry, crumbly clay.
