Fire Works Masonry working with friends at Iron Hammer Stoneworks recently completed a large, custom wood-fired commercial pizza oven in Hudson, MA. The picture below shows the completed oven firebrick core.
The oven begins with an insulated base pad, followed by the start of the firebrick core. The large oven floor measures 9ft wide by 5ft deep.
The oven floor is built using 12″x12″ firebrick tiles. The photo below shows the floor tiles cut to size before installation inside the oven core.
The base firebrick course and oven floor are completed.
The oven walls continue as the vault closes in. Temporary wood forms are inserted to support the vaulted ceiling during construction.
A stainless steel angle iron spans the wide door opening.
The vaulted ceiling approaches the closing final course.
The vaulted ceiling is completed.
The chimney transition is completed. The chimney will transition to a double wall, metal pipe chimney as it exits the restaurants ceiling.
A steel harness is constructed around the oven to resist the outward thrust of the vaulted ceiling.
Once the steel harness is completed, the wooden forms are removed from inside the oven. Below is a view into the spacious oven from the door opening.
The picture below shows the large oven floor space, shot from one end of the oven. The door opening and chimney throat can be seen on the right.
The firebrick core is tightly wrapped with 4″ of ceramic wool insulation. The insulation retains the heat of the fire within the oven core. The ceramic wool blanket is wrapped with metal lathe and then a rough coat of stucco is applied.
Below, the oven core and rough shell are ready for the final facing work.
