Elrond sees Bar as magic, but he also knows that skill and patience, among other things, may seem magic to the uninitiated. Which is which here isn't something he has delved into.

Clay is a simple fellow. He doesn't label it. IT just is the way it is, like the Forest.

Eric doesn't really care although the fact that he plays by the rules do suggest that he believes Bar is, at its heart, magical. You don't fuck with magic.

Unless it asks you nicely and bares its throat at the same time.
