[Stoves] Briquette stove in cob

[Richard Stanley]

Rok, 
Good to hear from you! Thanks as ever for your work on finding practical ways to extend the life of ceramic liners . Its an issue which has promised alot of folks as much -in terms of thermal insulation and resulting thermal efficiency as it frustrates-in terms of your mentioned issue of low structural durability. 
Do you find it easier to use a cubic shape for the clay sand exterior? I wonder because , it seems that a simple cylindrical form would be easier to shape and use less material and still be  as effective as a thermal ‘ cushion given the cylindrical shape of the rocket stove itself .

Dear stovers,

it's been a long time since I've written in the list, but we recently organized a Building with Earth workshop and one detail in the cob table was an integrated cooking stove - a ceramic liner, using biomass briquettes, same type as from Richard Stanley. 

It showed up as a great update to the holey Roket stove https://briquettestoves.com/ as durability is a big issue as ceramic liners tend to crack and break pretty easily due to temperature shocks, but the cob here is making it last for a long time. 

I have mixed local found clay and a lot of fine sawdust in the liner and it doesn't make any smoke, only when you push in a new briquette, there is black fumes for a few seconds, until a new one ignites.

If you happen to know any projects this principle would be good to integrate, even for other types of wood, I would be happy to share my experiences and possibly collaborate on redesigning existing stoves with this alternative solution. 

Happy and healthy cooking!
Rok
