Dried out it might replace perlite mixed with clay slip in the insulating layers of a clay oven. I doubt it would be more effective,( maybe mix with perlite) but I would like the idea of having my spent grains in there when I bake bread and pizzas. Here's a slide show we made when we made our clay oven a few years ago. Might not work on some mobile devices. : http://www.slideboom.com/presentations/218324/Building-a-wood-fired-earth-oven
