I have access to the bricks from a discarded electric kiln used to fire ceramics. I am wondering if these would work for a rocket stove riser or better used in some other part of a mass heater project.
Hi Philip;
Welcome to Permies!
A good score on finding kiln bricks to use in an RMH!
Although you could use those as a riser, they might be better used becoming the core of your RMH.
Morgan super wool creates a top-of-the-line riser in 5 minutes or less.
If you do use them as a riser, then you would want to use an insulating wrap around the outside.
For all your Montana Masonry Heater parts (also known as) Rocket Mass heater parts.

Bricks from an electric kiln will be highly insulating and not need a wrapper, as long as they are laid tight and there are no gaps. Kilns typically get up to over 2000F for several hours, with the outside more or less safe to touch.
