I'm trying to decide ring vs no-ring in a wood burning firepit. The ring is supposed to keep the fire/heat off the block and prevent them from cracking. But I'm worried that the ring will rust and not look good after a year or two.
If I go no-ring, do I risk bursting a block? I would like to glue or mortar everything together. I don't want a middle block to burst and have to disassemble to replace.
Or maybe I line the inside of the ring with another layer of concrete block or brick that can be replaced....
