3 inch Thick Firebrick ?

[Mistertoy]

I can get 3 inch thick firebricks instead of 2 1/2 inch. I have done a trial set out of the dome and it seems to be ok

I can get 2 1/2 inch thick firebricks as well but figure I will need less bricks if I use 3 inch and they are same price.

Does anyone have any experience with using 3 inch thick firebricks for a 36" diameter Pompeii oven or anyone have some advice ??

Thanks
Brett

No experience with 3' bricks here. BUT, the thicker bricks would be an advantage in that you may have about one less chain. Buy the cheapest one....

As you get to the top of your dome, three inch firebricks will leave bigger gaps, if you don't trim to fit. You may want to use the bigger ones on the lower courses, and switch to the smaller ones as you approach the top of your dome, if you can get both.

Here in the US, three inch firebricks are an expensive refractory specialty, so we don't use them much here.

Hi Brett,
Most firebricks in Australia are 75mm I used 230x115x75mm in my build and didn't have any problems.
Brett you posted on one of my album photos re; the entry arch angles I explained this on my build on post no 47.
