I wanted to check if this is a bad idea or not. I wanted to bring forward the front entrance to my cob-like oven a little bit while I'm setting up all my perlcrete insulation. It will move something like 5 inches forward. I first thought I might plop down some more cob made from my sand/clay mix around a sand mold right in front. However, this region isn't really a cooking surface and I don't necessarily want it heating up either. So I thought instead I'd form up the sand support like I was doing cob, but instead lay some perlcrete. This would form a perlcrete entrance, and one that would be unsupported overhead for that ~5 inches of archway. Will that hold up okay?
No announcement yet.
