This is the burn test of my Rocket Mass Heater. So far I'm pretty happy with it. The cast core is made with Portland cement and I am told that it is not a long term material. Fireclay should be used instead and I am guessing straw also for strength to prevent large cracks.

NOTE: The highest temp my flue reached (at about 7 feet off the floor on its way towards the chimney) during this entire test was 150 degrees F.
