Doesn't Khalili fire some ceramic structures from the inside, build it with
unfired bricks and then build a hot fire inside to fire the bricks from the
inside.  Since this is a sweat lodge, you should have a fire hole in the
roof anyway.  Seems like this would be a good application for Khalili's
fired ceramic structures.
