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? link to the youtube video (absolutely no affliation or link to me!)

That is insteresting. I may do some trials with that. I could easily make some thin plates to line something cheap like cement board and easily make a burn chamber.

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.
