Does any one have, or has anyone used vitrified clay pipe as a riser? It would be insulated with rock wool. The pipe is supposed to be able to take over 2300 degrees f.
Clay tile/pipe can stand high temperatures, but it cannot handle fast temperature changes like you get in a RMH core. People who have tried it have found that the tile cracks, sometimes badly.
They gave me pumpkin ice cream. It was not pumpkin pie ice cream. Wiping my tongue on this tiny ad:
Quit your workee-job and live, year round, for free-ish in Montana
