A round dome masonry oven styled for family gatherings in an Eastern Ontario backyard

The Gathering

The round dome. Pompeii's shape, unchanged.

From $18,800 plus HST

Why this shape

The dome hasn't meaningfully changed in two thousand years because it was already right. Heat comes off the curve and back down onto the food from every direction at once, while the floor cooks from below. That is why a pizza is done in ninety seconds and comes out even, instead of charred on the side that faced the fire.

It isn't actually round

A Pompeii dome is not a half-sphere, whatever the pictures suggest. On a good one the radius across the floor is greater than the height at the centre. The dome is deliberately flattened.

That correction exists because of the floor. Nearly all the heat cooking the underside of a pizza has come down off the ceiling and gone into the brick beneath it. Build the dome to a true hemisphere and that heat has further to fall than it should — the chamber runs hot, the top chars, the base stays pale.

So we step the courses in as they rise, bringing the ceiling down closer to the floor. It is slower to lay and it is invisible once the render goes on. It is also the whole reason the base of your pizza comes out crisp.
