Are you saying to put pots around the rim ???? I thought heat sinks
were used to pull heat away from an object. My thoughts are not to pull heat
away from the rim but to get the heavy bottom to cool faster. What i do is
space
the bottom from the shelf to promote air movement on the bottom surface. Since
i started doing this i have not lost any big forms. I hope i am
understanding you
correctly. Putting pots around the rim would act like a blanket and hold
the heat
around the rim so it would cool slower ... is that what you are
saying....Dude !!!!!!!
What about putting the pot upside down during the bisq. fire. Do you
think that would
have the same effect as the above mentioned... Thanks
