I am starting to think about the finish for my cob oven that I covered over in perlcrete. We've used it a few times and its down the typical thing; out the front it's sending burn marks up and the flue is got a lot of soot and general scorch marks around it too. I've seen a lot of pictures of dome ovens with that happening. I wondered if there was something I can do about it in the finish, or if I'll have to just embrace it and make it part of the architecture somehow.
No announcement yet.
Preventing scorch marks or making them cleanable
