Idea parabolic dome design/dimensions

[di11on]

Hi folks,

I've read before that the oven dome should have a parabolic cross section.

This seems to make sense as all heat rising upwards is reflected downwards to the focal point... the same principle as a satellite dish. So, where should the focal point of the oven be... where you're going to put your pizza/bread? If so, where is this exactly? Right on the oven surface in the centre, or slightly above or below?

I don't think it works quite like that. The heat transferred from the dome is mostly convective and it is not reflective or radiant heat.

Also, I would think you would want to avoid having a focal point
'hot spot" because you want even heat distribution throughout the oven.
