Roman heating worked like this: hot gases were vented into cav | UNITED STATES OF SECRETS 🇺🇸
Roman heating worked like this: hot gases were vented into cavities in the walls and floor, heating the dwelling, only then escaping through the chimney from the house. But this system consisted of fireclay bricks, found by archaeologists.
The problem is that fireclay bricks are fired at 1'300-1'500°C in rotary kilns.
No idea how an ancient Roman could get it if the wood produced a maximum of 900°C and the coal 1'200°C? Not enough temperature! And that kind of temperature became possible closer to the 15th century. The Romans just didn't know they didn't have the right technology. Well, either the dating is wrong by a thousand and a half years. Or history is deliberately "aged" and "ancient" Rome was in the 15th century.
