That depends on how thick the cob is and if you cover the cracks on time. In this case mine have already started to burn but the stove remains standing though not for long as I still not cover the cracks.
I'm building a new one because this model was pretty failed, soon I'll share the new project.
Thanks!
I would like to see the details of the new project here
I'll give you an exclusive preview 😉
I'll tag you later when I upload the post
Okay, thank you. It looks good
