2700F melting/boiling point... interesting... but it is also 45% limestone, im guessing it would be great for the mass area. as far as the burn chamber and feed tube, and riser (flame path) i would like to see some testing done on it, because of the lime content...
it might work, but i only know one way to find out, test it...
it looks like very unhealthy stuff, many safety and health hazzards so be careful if you work with that stuff.
