Has anyone here tried coating the inside of the burn tube with a thin starlite type intumescent mix made from household materials?
I watched a YouTube video by NightHawkInLight (1.67M subscribers as of just now) today that gave ingredients and instructions for making which seemed trivial using very simple household ingredients. Given the aim is to have the burn tube as hot as possible, this would seem a pretty neat not to mention cheap way to achieve this, even if it had to be recoated every so often.
Possibly one could get away with standard house bricks if one insulated them like this,but presumably cob would last a lot longer too if protected.
Any thoughts? Maybe someone with an existing rocket stove would be interested in adding a thin coating to see?

It's funny you bring thus up. I actually made a very small, 2", batch box a while back from cardboard and NightHawkInLight's DIY starlite. The riser was made from tin cans and was insulated with starlite. Not an ideal rocket by any means. It didn't run very well I think because the starlite was still moist. It did char and protect the cardboard from the flames at first, but eventually the starlite gave way and the whole thing burned up. It was a fun experiment, but I don't think the material would be good for long term insulation. The carbon foam is very soft, so you'd probably have to repack your stove regularly. I'll see if I can dig up any photos.

Found 'em! I even had a little p-tube made from aluminum foil...little did I know p-tubes are unnecessary on open systems...woops. Sadly I didn't take any pictures of it going. It wasn't much to see though to be honest. Lots of smoke

deadstarsstillburn: Hi there. I was directed this way by folks on the Permies.com website and am hoping I can get some information on how a total newbie can get started designing, siting, building, and not-dying-in-a-horrible-house-fire with a new RMH in a 160-year old home

deadstarsstillburn: The people over there recommended either a 6" batchbox or an 8" J-tube. I don't know what those are but am going to try to figure that out. What I need is a blueprint that I can scale to fit the need for my house. I have something likne 5000 square feet

deadstarsstillburn: but I do not need to heat all of it by any means. probably only need to heat half of that, maybe less.

deadstarsstillburn: moreover, the house has 3 storeys (large attic) so I assume if I get very efficient heating on the ground floor, that will go a long way toward heating the upstairs as well, no?
