I have seen that chap honeydew (or something like that) but I did not get how he was making it heat resistant?
It just seems a little bit null and void compared to the 5min riser concept?

Mart Hale wrote:What I have learned with my test setup,
A thin layer of aircrete does not hold up very well, I had 1/8th of an inch and it did not work.
Using cloth and concrete in the riser just does not hold up.
I have found extending the burn chamber with a chimney pipe increases the burn as the pipe heats up and warms the air entering the pipe.
I have learned much from my test setup, will build another and see if I get closer to my goal of having a rocket stove that burns long enough to cook without me having to watch it.

What ingredient are you missing? I may be able to help you source it as I have been gathering these things also.

It's commonly available at the Home Depot for around $20.00 for 50lbs.

I want to try it in other forms:
-Ferrocement with basalt reenforcement instead of steel.
-Hot face for rockwool or ceramic insulation.
-Aeroconcrete firebox ,riser maybe even bell.

This is true. However the only location that one can cook with it is at the barrel. I was thinking what if that barrel was put in the middle of a cob oven? would it not heat up the thermal mass of the oven to a high temp, and keep the smoke out of it like a standard cob oven?
I am not sure of this, but something I would like to test.

Actually you have additional options, for example Matt Walker built a RMH in a corner ( https://youtu.be/v20dCSxV5ow ) and has tried a heating plate as well as a door that gives access to a space just in front of the wood feed, away from the burn tunnel from what I could see. He's baked bread in it in one video, and I think mentioned cooking soup as well. Not a huge cooking area of course, and introducing points where heat is removed will lower the burn temps and efficiency of the burn.
While the barrel top is a convenient spot, those who are using brick or earthen bells instead seem like good candidates for including a recess or two near the top where you could remove a brick to expose a thinner surface that heats up quicker and gets hot enough for cooking.
