A quick, 8-page guide to our favorite alternatives for this critical part of clean-burning Rocket Mass Heaters and Rocket Cookstoves.
There are not a lot of materials that perform optimally at temperatures above 1000 F. This "cookbook" gives you pros and cons of some popular materials, and ways to build either campfire cookstoves, or permanent installations for rocket mass heaters using the appropriate materials.
This cookbook is not intended to provide complete building instructions for rocket stoves, just alternative ways to build the heat riser that powers the whole works.
It will be most useful to people who have already read the Rocket Mass Heater Builders Guide, taken a workshop from an experienced builder, or otherwise gotten familiar with the basics of rocket stove design.
