Curing a Heat Riser on Rocket Mass heater

Darwin has designed a custom, rocket mass stove. He is pouring the heat riser, from his own unique mix. It is light weight, made from air crete using his foam mate. We let the mix sit for three day now we are heating it up. Do your own research and we do not take responsibility. Check out our shop http://www.etsy.com/shop/HoneyDoCarpe...
