This is such a good reminder of just how hot parts of a rocket stove can get and how important it is to inspect things carefully, and design things so they *can* be inspected carefully, particularly when you're experimenting! I've been gradually collecting the things I'll need to do an outdoor one for learning on, but I'm totally cool with learning from other's mistakes! Thanks for the great pictures, Gerry.
Long story short, I don't think this is ceramic fiber blanket, superwool or whatever else you would like to call it. It may be a high heat insulation suitable for oven temperatures but certainly not what will work for the extreme temperatures of a heat riser. Sigh!
It looks like your stove manufacturer used a lower grade insulation. I'm not surprised that there are variations on the construction across different models, but it's the first I've heard of it.
You can find superwool online at Amazon for reasonable pricing. If you are unsure or not willing to experiment then that's likely a better source for you.
Sure, you are welcome to share my thoughts, thank you for asking. Thanks for your continued support as well, I greatly appreciate you and the gang over there and all the support over the years. Let me know if there's more I can do to help.

I have had one for a few months but not actually fitted it yet......

Jay Angler wrote:Being able to lift it to clean under it sounds like a good plan to me. Hubby has some sort of heat-tolerant silicon goop that he's used on our wood stove - would a small bead of that to seal and support but not "glue" in do that? I will keep watching this thread to see where you go with this!
That said - the ultimate question is: if someone dramatically boils over a pot, where will the mess end up?
True story time: Years ago we bought a glass-topped convection oven from a reputable brand. I specifically wanted the element dials on the front like a gas stove so I don't have to reach over hot pots to turn them off. The only one we found that fit the bill had the new electronic system for oven control, and this was also mounted on the front. It had a lock on it, and no small kids here, so I figured I could live with that (the element knobs just pull off to make it safe for young children). We were asked to host a couple of Japanese school girls for a week, and they were instructed by their teachers to "cook us a Japanese meal". They managed to boil over the pasta, and the manufacturer had failed to put a proper seal between the front of the glass and the front of the stove, so the pasta water dribble down all over the electronic module. Luckily, hubby is a consummate fixer and electronics engineer, so he took the front of the stove apart, cleaned the electronics as best possible, and got things working. I insisted we call the company because there's no way I was going to put up with a stove-top that couldn't tolerated spills! Now that some sort of gasket has been installed, we've not had any more problems and the stove is now about 10 years old.
Looking at the design of the cooktop in Allerton Abbey, it looks like there is a rounded wall around the entire perimeter of the glass top. I'm assuming a boil over would then stay contained like a swimming pool. It would not be good to have liquids dripping onto the hot bricks inside the stove which could crack from the thermal shock.
If the glass was made removable without a silicone seal, this could happen. Always a catch to consider isn't there?
Yes, I can picture something like that. You'd have to push it to the hole or else have the cook top on a very slight slope which is not ideal if cooking things like omelet in a fry pan, but would be fine for many other dishes, so again, decisions and compromises!
Gerry Parent wrote:Jay, I remember at our cottage we had propane grill which at the back middle was an oblong drain hole where all the bacon grease or whatever 'shlop' you wanted to get rid of got pushed to which then was channeled into a pan below for removal. All the sides were slightly raised so it was kind of like a really shallow tub where things had to go down the drain instead of over the sides. Perhaps something like this could be incorporated into the design?

Jay Angler wrote:The insulation isn't good enough for inside a RMH, but are there other places where it would cope? For example, we have a collapsible metal camping oven. I had hoped to be able to use it on top of our regular wood stove (Pacific Energy) but it looses too much heat through its top and sides to actually be useful in that location. I've always wondered if there would be some way to insulate it enough to actually work?

Re-use isn't quite as good, but it's still a big improvement over the landfill.
