bricks for experiments

can you use regular red bricks for testing out a rocket? or can you use cob for the feed and burn tunnel? Not for thw final stove...just to test outside.

Yes. I got a deal on some red bricks from a 100 year old schoolhouse that was being torn down. They work great and I have been experimenting piling them up in different arrangements and seeing how the rocket stoves work.

thanks. also thinking about stacking them in my fire place to rumfordize it, kind of like Ernie did in the first fire DVD.

Just thinking about it? Get to it, man. The other day when we had that hard freeze, I was pushing lots of wood into the stack I have in my fireplace.

Yes. Done it.

I wouldn't use the bricks for a final build. Red bricks are great to play around with but they absorb the heat.
