Hi. Do you think the fire bricks shown in the photos are suitable?
The thickness is 50mm.
The bricks are more than 10 years old and have been sitting in the weather. Location is Perth, Australia.
I would say half the bricks show cracks as seen in the photos and the rest are just waiting to crack I think. They spall quite easily and if you run your hand on the spalled portion it feels like hardened sand which is easy enough to degrade. Is this common with fire bricks? These seem so much softer compared to clay pavers.
The person mentioned his oven takes 3-4 hours to heat up properly with the same type of brick (built over 10 years ago).
Comments appreciated on any of the 3 issues (thickness, strength, heating time).
