Hello Erica and Ernie

My cast core is 3 inches away from the lid. But I don't want the flame to lick on the lid all the time to wear out the lid. So I get 3 firebricks and motar them together to with two legs which is also firebrick. The thickness of the firebrick is 1.25 inches and it is also the high of the space between the cast core and celling. I put it on top of the cast core (like a hat) so the flame will lick on it rather than the lid to spare the lid for longer life. This will take longer to heat up because the lid will not heat up that quick. But my concern is would 1.25 inches is too little space between the core and celling? Would that cause explosion? Especially I have the two legs which pretty much cover to side of the 4 side of the core (my core is firebrick)?
