Cement fire Bricks??? Help!!!!

[kriso]

Hi there
I am getting to the end of the second hand hunt for fire bricks, the first clay bricks I got I was informed were crap, then I had some old clay bricks that had holes but these are no good, not can some one help with this latest edition of bricks (I am going to own a brick yard soon), it came from a chimney so I am hoping it will be ok, however I noticed on two bricks had some pitting.....not sure how old they are but they are very heavy for a little brick. they are a concrete mix i am gathering.
Please see attached photo.
Looking forward to your responses

Yup, defo concrete and no good for a pizza oven, might be good to add mass, but a real no no where fire is concerned as they will spall and explode under high temps.

What area are you in.... cos there is a manufacturer in Auckland. I also have left over bricks...

I am in Rotorua. What kind of brick did you use? I would appreciate any assistance.

The company here in Auckland is Certec. They actually make an oven that they sell as a kit but I opted to buy some of their "Seconds" refractory bricks.
Welcome to Certec
I think I paid about $5 each. Then I picked up 80 fire bricks locally on trade me for a couple of bucks each.
I still have about 25 left so my dome (800mm ish across the base) must have only used about 60 bricks excluding the base.

Man I thought we had it tough getting the right gear/tools etc, but you guys over the ditch seem to be worse off for choices....

Yeh I know, things are tough here, well easy to source if you have the cash, but unfortunately I have a cap on my build. I have managed to source some second hand fire bricks for $4.00 each, however I have to drive about 2.5 hours each way to get them. the best locally is $6.50 each.
Will keep posted about the build.
Cheers
Kriso.
PS did you manage to have a look at the monier website for the Pompeii pavers?
