XL Egg...Is this safe?

This is not quite the same as a paver. Bobby-Q from BGE may have some input on this.

With this setup you will still have RADIANT heat hitting the wood where there is no fire-brick (remember the three kinds of heat transfer.. conductive, convective, and radiant). I'm not sure how well this might do at high heat. Basic laws of thermodynamics say it WON'T provide the kind of thermal isolation that a paver which is at least as large as the bottom of the BGE would provide.

Just my two cents.

I would feel safer using a large paver.
At the least I would add a BBQ mat under your 3 pavers.
Home Depot in our area have them on sale now for about $25. It could be cut to cover the entire bottom shelf and it's only about 1/4" thick so it will not push your egg any higher in your table. This will also help prevent a large spark of lump causing issues on your wood bottom shelf. Would also give you a safer place to put hot racks and platesetter.

IMO no.

I would trade-in the 3 individual bricks for one much larger one (like the stepping stones) to cover the entire bottom and provide better stability.

WPB,

There is induction and some others also but they do not apply in this case.

WPB,

I guess you are right. The heat is caused by induced electrical current. I wasn't talking specifically about cooktops but that is the process. You could say the same anout convection though couldn't you?

Steve

So conduction would be the only transfer that does not require another medium. :laugh:

Steve

Next time you make pizza, wait until the egg is stablized, then take your thumb and stick it down on the plate-setter :woohoo: ...that third degree burn you just got was a result of conduction (and required no medium such as a gypsy fortune teller).

Oh, and I'd go with PhilsGrill solution. Several firebricks arranged to provide a uniform, stable, and heat resistant surface. I'll probably go this route with my new table.

I am only cooking on a large in a table, not an XL. We have the firebrick lined up next to each other. I think we have 6 under it, it's dark out so I can't go count.

We cover the whole bottom area under the egg with firebrick, not that couple just to raise it up set up in the picture.

I use 3 terra cot pot feet under mine. You can get them at Home Depot or Lowes for about $2 each and you'll get circulation and keep your eggfeet for under the dome use.

I am not sure why they do not recommend using feet for the XL. It probably has to do with the stresses formed from the higher weight of the XL and that larger flat bottom. Your bricks give a lot more support than three feet, but I do not know if you are still at risk of breaking the bottom and how that would impact your warranty.

Assuming you have enough support, I would put down a paver or just a ceramic tile and then put the bricks on top of that.

As it is, you still have bare wood exposed to the heat of the bottom of the Egg. They are probably thicker than the feet (more air space) but why take the chance?
