Re: Starting my barrel vault
Another alternative is to use insulating fire brick to buttress the walls.

The only advantage a barrel vault has over a dome is its interior form which makes it more suitable for cooking large batches of bread.

This is the general rule for kiln building, where temperatures are much higher and expansion is greater. The expanding vault has a tendency to push the end walls out and steel bracing is required to hold them in for kilns built this way. It is a bit more tricky to build the end walls first and then the vault over the top, but the result is better. The same applies for ovens although the problem is less because the temps are lower and thermal expansion is smaller.

Re: Starting my barrel vault
Hi, I am building a barrel vault similar to yours. I notice you did not use any buttressing on your build. I am having a very hard time as i dont know how I would use it. Does your vault has any buttressing?

And the soot will return at the start of each firing.
