Pumice should be relatively easy to get. Pardon the ignorance, but would you crush the pumice to mix it up in the concrete for the hearth? Or would you the stones? I guess it depends on the size of the pumice stones.

I'd be really interested to hear what you think. At this point, finding vermiculite is one of my materials issues.
