Hello, We have been using 1” perlite as insulation beneath a clay combustion chamber with very good results. Before using the perlite we had tried ash with good results also. We decided to try the insulation to prevent heat loss a few years ago when designing the prototype of a Rocket stove (the Isleña stove). The perlite is enclosed inside the stove body, around and below the combustion chamber. A removable metal grate for air flow under the fire is placed inside the clay combustion chamber.

Could anyone help me out with this - would an ash layer beneath a fire in an improved cookstove (as in the sketch attached) help insulate the fire and prevent heat loss into the body of the stove? The layer would be about an inch thick after compression, and is about half an inch below the base of the stove.
