Funny that you would say that, as today I picked up a huge s/s metal halide lamp housing. It is a like a polished 30” food mixing bowl and fits on top just right, I also have a rotisserie motor that I want to try.
I made a five minute riser and exchanged it for my refactory riser, it did take me a little longer than five minutes as I built it up with two layers of 1” blanket and squeezed it into a 10” stainless pipe. The effect was a much faster warm up time, I managed to measure 500c in just one hour compared to the previous two hours, that would seem a huge improvement!
In fact I got to 547c in the dead centre but then the little piece of glass cracked in two and I destroyed my iPad while trying to film down the riser. What I did notice was the need to keep the fire really stoked and full of wood unless the temp would drop quite quickly.
With my old riser, once the plate reached 500c, would stay there with very little attention to the fire, I guess the 50kg of refactory was holding the temp in place. The other issue is the amount of fly ash that has already accumulated after only two fires, I did not really have any before?
I see there is a hardening product that can be applied to ceramic blanket but it requires 800c to really be effective. I don’t know if there are other products available because I would much rather see a smooth and hard inside to the riser.
I can only find one company in the U.K. selling ceramic blanket hardner www.creativeglassshop.co.uk/product/31306/colloidal-sillica-hardener-1ltr.html I spoke to them about the product but they just conformed the site info, it really needs 800c to set very hard although it will set to a lesser degree at lower temperature. I guess I will have to buy some and test it but I actually live on a small island and the postage cost for toxic liquid is very prohibitive. So I might have to wait until we next take the car to the mainland. In the mean time I have set up a decent vortex but simply jamming a bit of stainless at the end of the burn tunnel, I will be lighting the fire tonight so we will see how it goes this time....
We had a few friends around last night, we cooked steak and lobster (farmer and fisherman friends) it all went well, I was too occupied to take any video but the hot plate was 475c after one hour. We aslo cooked some chestnuts and as a finale we melted some mashmellows over the exposed heatriser, all good fun but at my age ... not so good this morning!
We did not vote as we are a independent jurisdiction, we have our own government although our passport is U.K. based ! Most street names, house names and many surnames are French but most people speak English, in fact our local patois is not even taught in schools anymore. I don’t know what effect Brexit will have but there is concern with the offshore banking (the islands main income )
Chimney is not connected but can be quite easily, I did have a rotating plate over the outlet so I could control the flow through the system, this is good in the summer. It is nice to show folk how the fire operates smoke free and the exposed chimney lets out cooking smells. The whole party house area is well vented as the structure is just made from fence panels.

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
