Limited Space!

[Masako Morishita]

Because of the lack of space my my oven hearth measures 49" in width
x 59" in lenght so how small of a pompeii oven can i build or should it be better to go with a small vault type???

Hi Masako Morishita
If you build using the standard brick 9 x 4.5 x 3" cut in halves making your oven walls 4.5" thick with 1 or 2" thermal blanket and then 2 or 3" vermiculite cement and topped with say 1" stucco, then you need to allow at east 9" each side for the walls. If my maths still serve me, a 49" hearth will be reduced to 31" inside diameter.
You can increase this amount to a 34" internal diameter hearth if you turn your dome bricks to 3" thick with the same insulation. This will work fine, it will heat up and use less wood (which I think you claimed earlier as a rare or expensive resource) but will not have the thermal mass to hold the extra reserve of heat to cook numerous loads of breads etc but fine for pizzas and a couple loads of bread before cooling down more quickly. There will still be just enough (in my opinion) for a suitable chimney void at the oven entrance.

Re: limited space!

I agree with Neil - my oven is built with the bricks oriented as he suggested and it works great for Pizza and has sufficient heat retention to cook bread and we even cooked a turkey last november - after cooking pizza the night before with no added wood!

Have fun!
