Earth oven collapse
Well this sucks. After many days (and a few dollars) I finished my earth oven last friday. Two layers (thermal and insulation with straw mix). I didn't have time to cover it and it rained heavily today completely collapsing both layers of the top of the dome.
I had to buy fireclay and I don't want to have to do that again so reuse is crucial. . Anyone have ideas for rebuilding without refilling it with sand (which would basically be impossible, plus my sand is now gone that I used the first time)? I don't want to tear it all down because I think I'll lose too much clay and end up with straw mixed throughout.
If I have to tear it all down I may just rebuild with firebrick instead of earth.
Any help or sympathy?
