Our latest project is the construction of a hand-built, site constructed domed wood-fried pizza oven in New York City. The Oven has a 60″ diameter floor. The oven design is based on the impeccable work of Alex Chernov of Stovemaster.
The photo below shows the completed oven firebrick core with a stucco shell exterior. The oven is ready for the chimney exhaust connection as well as final external tile detailing. The opening in the block foundation will be used for wood storage when the kitchen work is complete and the restaurant is up and running.
The large working space and completed dome for the wood-fried pizza oven are shown below. The dome construction consists of all high temperature firebricks cut for very tight, strong joints. The oven floor is constructed of 12″ by 12″ firebrick tiles. The fire will be constructed on these tiles to heat the floor of the oven as well as the dome. The restaurant’s delicious pizzas will cook directly on these heated tiles.
Below is a photo of the start of the oven construction. The oven walls and first course of the dome have been set. The oven is constructed on top of load bearing, high temperature insulation. This insulation layer supports the weight of the oven while also isolating the heat of the oven, keeping the energy of the fire inside the cooking area.
The construction of the dome continues. All the brick courses are cut with a compound miter to ensure very tight, interlocking joints. Every brick acts like a keystone, locking every course in place.
The photo below shows the oven dome closing in.
Below is a photo of the same course as above, viewed from inside the dome.
Below, the dome brick coursing and chimney transition are completed.
The completed dome viewed from the inside.
Once the firebrick core is complete, the oven is wrapped in high temperature ceramic wool insulation and metal lathe wire. The ceramic wool insulation keeps the intense heat of the fire inside the oven dome, working on cooking the pizza.
Next the oven is covered with a rough stucco coat over the lathe and insulation.
The wood-fired pizza oven is then covered with a colored stucco coat. The oven is ready for the chimney connection and final tile detailing. A soapstone transition piece is set on the oven opening, ready to receive the new restaurant’s pizzas.
