    Today hit the highest temp ever, over 803 deg F….

    It was a bright sunny day, I had replaced the wire with silicon covered wire..

    Also I removed some of the sand and I put a 12 inch long rail road rail in the dutch oven with some sand inside.

    I believe if I opened this up and put a pot on the top with water it would instantly boil……

    I am most curious how long this will take to cool off……

    The real questions I have now is how much mass can I add to this equation, as bricks or steel, and how does that affect the cool off time?

    Hitting this temp blew me away. Tomorrow is another sunny day, I imagine I will have some residual heat and the temp will get higher.
