The oven is taking form. It has been a bit intense around here for the past two weeks, to say the least. The weather has been chilly and wet-ish, so I guess we aren’t missing much. When I last posted, Tim was preparing the ground behind the bakery in preparation for the concrete footing. Now he’s out there fiddling with the last two rows of bricks that form the oven’s arch. (Needless to say, I am inside today baking cookies and writing blog posts). There were several steps in between pouring concrete and laying arch bricks: I’ll let the photos do the showing.
The concrete footing is poured – thanks to Dominique and Heather for the use of their mighty orange cement mixer!
Tim and the first few layers of the concrete block plinth. Is he working or just drinking tea?
What is he DOING in there…… ?
Making the form (or “shuttering” as Tim keeps insisting it is called) for the upper concrete pad – the one on top of which the oven will sit.

Pouring concrete! Luckily it didn’t rain on us that day, although just as we finished a big hail storm swept over and pitted the top of the concrete with little holes!
The weather forecast – let’s get a roof built over the oven area SOON.
View (from inside the bakery) of the hearth bricks being laid. The ash slot is visible in front of the bricks. All is dry under the new roof.
The second layer of hearth bricks. Two layers of hearth bricks will increase the thermal mass of the oven. The hearth bricks are laid with fireclay between the layers, but no mortar between the bricks.
The oven walls finished, with the door frame in place as well.
Tim, getting ready to start the arch. Anyone who stops by for a visit gets a demonstration of the counter-weighted door in action!
The structure viewed from the outside. The layers are, from the bottom up: concrete blocks, cement pad, foam glass insulation, cement backer board, bricks.

Ta da! It stays up! Those Romans, eh? The arch bricks have no mortar between them on the inside edges.

The arch bricks as they come down to meet the doorway – each brick is custom fit – no mortar!
