Hello to all
I am at the stage of the insulating hearth for my 42" Pompeii, and planning next stages.
The Australian firebrick suppliers I have contacted have 9"x4.5"x3" bricks(230x115x75). I would use these on the oven floor and for dome.
An alternative floor brick is a 12"x12"x2" tile(300x300x50) (I may also be able to get a 12"x12"x3" tile, but currently N.A.)
Given I will have good hearth insulation, would the 2" tile be ok, or is the greater thermal mass in the 3" brick important?
Secondly, I can also get 3 different angle arch bricks at the same price as straight bricks.
- 75mm/51mm
- 75mm/63mm
- 75mm/69mm
Is it worth checking the angles of above, and considering building the entire dome out of arch bricks? (= less gaps to mortar?) I guess it would depend on the angle being just right, or you would need to shim anyway?
I look forward to any comments. I will get organised soon and post some photos I have taken so far.
All the best, Andrew
