Loud cracking sounds coming from inside the egg

I was getting our LGBE up to temp last night for pizza, same protocol as in the past, fill it to the base of the fire ring, light it up, wait for the coals to have a good glow, put in the ceramics/grid/fire bricks/pizza stone then close and walk away to let it warm. At around 150C there were some really loud cracking sounds from the egg base. I carefully opened the egg, and the cracking stopped. Put the lid down again, same thing happen a couple of minutes later at around 200C. Opened the egg again, nothing untoward, closed the lid and kept heating. No repeated experiences even at 400C.

Opened the egg this evening after everything was cool, cleaned out the egg, no damage to ceramics. Only thing I can think of was lump splitting in two and pinging off the side walls of the egg.

Anyone else experienced this phenomenom?

    Or a rock in the lump exploding. As long as everything looks good, keep egging!

    if it is a higher pitched 'tink' sound, it's actually the lump

    other than that, no idea

    Just a possibility, but were you using a cast iron grid? Those often crack, quite audibly. Sometimes a piece actually breaks off and falls into the lump. Other times, it just cracks in one place (hairline) and it's harder to notice.

    Speaking of CI, did you check the fire grate? I've never heard mine, but it's definitely cracked and I suppose it could have made noises when it did.

    I hate it when I go to the kitchen for food and all I find are ingredients!

    The sound was akin to that of a stone hitting a window, not high pitched. So that's good to know as I didn't know that lump could have rocks in it. That would explain the occasional piece of fossilised detritrus that I find at the bottom of the egg when cleaning it out.

    Fire ring and grate all in tact.

    Thanks folks.

    Good thing it didn't break...the right member comes along they would have figured out a way to twist it around so that your methods were the reason it cracked...just saying...

    Yeah, because this OP comes on the forum everyday with a new "issue" that "happened out of no where".  

    You'd give Time magazine a run for the money on number of issues.

    Probably just the lump if you saw no damage.  See if it happens again.  When mine cracked, it sounded like someone shot a .22 in my back yard

    Yeah seems like you have had a run of bad luck that would turn goat piss into gasoline. And no real help from here. IDK. Keep on keeping on Doug. WTF else could I say?
