Day 10: Arch and Flue

The flue opening is the least well documented part of the Forno Bravo plans. I found some proportions of 2:1 of flue to flue opening and followed that. [later I would realize that my flue opening is much to small!]

The flue opening was formed by cutting out segments of the brick arch over the oven vent/landing. I decided on a metal flue, and mounted the flue pipe base directly on top of the flattened top of the flue opening. I spent the rest of the day covering as much of the dome exterior with mortar and filling large gaps with bits of brick. I got about a third of the dome covered before I had used up bucket number two of refractory mortar.
