Experimental rocket stove made with rice/hull clay adobes for insulation and traditional adobes.

“Two kinds of adobe: one regular old adobe mix and one that’s rice hull/clay. I wanted to try out the rice/hull clay thing as insulator.

I didn’t have very many rice hull bricks, so I put ‘em at the bottom of the heat riser, the hottest place.

Did they harden brick-like with the heat?
Yep, on one side. The regular adobe ones did.

With the rice hull/clay ones, the clay fired and the hulls cooked out leaving voids, char and fine ash. They stayed quite fragile, though (as I’ve said before) I don’t think that’s a problem as where they go best there will be little physical shock, that is banging around.”
