IF YOU CLOSE OFF THE PATH FOR THE AIR TO ESCAPE THEN THE HOT AIR WILL "SPILL OUT" FROM UNDER THE POTSKIRT

SO WHATS THE PROBLEM, WHY NOT JUST HAVE A STRATIFICATION BELL OVER THE POT
WELL ITS THE THERMAL GRADIENT
YOU WANT THE HOT AIR TO STICK AROUND THE BOTTOM OF THE VESSEL AS LONG AS POSSIBLE, AND SOAK THE HEAT IN THROUGH CONDUCTION, NOT SIT ABOVE THE WATER AND MAYBE GIVE A TINY TRICKLE OF HEAT THROUGH RADIATION
