The Oven is Taking Shape!

Here's the latest in-progress photo from Forno Bravo about the oven they are building for me. The guts of it are taking shape. That looks like wood framing that's used to pour concrete or something for the chimney that curves from the front of the oven back to the top for the center chimney.

This is the cross section design of the oven (via this PDF):

Knowing that the inner dome has to be solid for heat and flame reflection, I always wondered how these ovens have a central vent. This is how... the air goes out the front and gets routed up across the top of the inner dome to the chimney.

Awesome!
