I’ve been looking into brick oven design, and the dome shape is motivated for two reasons: (1) “Retains heat efficiently,” and (2) “Reflects heat evenly”.
I’m confused about both of these things, since I’d expect the bricks (not air) to be primarily “storing” the heat, and because I have no idea what it means to “reflect heat,” let alone evenly. Any explanation would be really helpful.
A related question is basically, “why couldn’t a brick oven just be a short and wide rectangular prism?” More like a conventional oven. Why is the dome shape thought to be needed.
