Given that tiles are fired to temps above that found in the cooking stove, I wondered about the feasibility of using tile (either glazed or unglazed, clay, stone, or ceramic) as a lining in the heat riser.
Depends on the tile. Heat shock is the major problem to overcome.. Strangely enough, firebrick with a higher fire tends to crumble more than the stuff at lower fire. They are formulated to handle higher temperatures in applications with longer and fewer heat up and cool down cycles. I've noticed that (for instance) soft, red brick tends to last longer than fire brick even though the red brick isn't really meant for the job. I have heard that clay pipe doesn't work well. Heat shock wipes em out fast.
As to your tile, you just have to try it and find out.
Here's where cast refractories will come in nice. I've seen things as simple as the clay/sawust bricks built up, with a chunk of fire-brick at the back of the fueling zone to take the sticks being pushed in.
I've been meaning to look at fireplace suppply stores to see about fire-brick in thin slabs, instead of the regular bricks. Especially for smaller models, we don't need the mass of the full fire-bricks stacked.
We need to move up to castable perlite/pumice and something more durable than clay. Maybe an inner lining of thin layer of a more durable concrete-like refractory, then the filling of insulator, and the outer body. Definitely have to look at the different curing/pre-firing needs of the different layers. Probably cast sections of the needed shapes to be assembled, instead of a full casting of the inner guts, then cast the insulation layer around that.
I'm wondering if the short-lived first iteration model could be used to fire the bricks of the final model?

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?
