48" Dome Pizza Oven with Pat Manley and Marty Pearson

The base is in place.

The half dome is started with a 48" circle to mark out the inside oven floor.
Half firebricks (bats) 4.5" x 4.5" are used.
The mortar is 3-4 parts sand plus 1 part Redart clay.
The joints are wedge shaped.

The firebrick floor is installed onto a bed of mortar. There are dry joints between the firebricks.

There is a holed drilled at the centre of the circle on the floor. The wooden guide stick visible at the right top of the
bucket, is used to maintain the hemishphere shape.

Some of the firebricks are wet, and don't have enough suction to dry out the clay for an initial set.
Bricks and sticks are used as temporary props.

Continuing work after supper. Fog has rolled in on the mountain.

Getting close. This is the hardest part.
There is a temporary support underneath, with mud built up to get the right height.
Once the final brick is in place, the support can be removed.
