Woodfire Oven first build

[billybob1]

Hello guys and girls, im in the process of gathering materials to start building my woodfire oven and where i'm located fire bricks are hard to come by. i was wondering if there is an alternative?
was thinking hebel? I apologise if any of this seems silly.

Hebel is not a suitable product for the main oven structure. It has been used by many Aussies for the base structure for the oven but not the oven itself. You can consider a refractory cast oven., DavidS is from Queensland and is our resident casting expert. It seems that Melbourne Fire Brick Company offered fire brick although costly.

Thanks for that. how do i go about filling the holes between the fire bricks for the base?
