With the advise you get there and here on the forum you will be cooking in no time. Where abouts in Sydney are you from?
Good call, Leigh and Alan @ FFR can look after you really well.

You post the photos as you go Tony and you will get all the help you need from the forum. If you are unsure of what to do, ask the question first, get lots of answers and then go on with your build. There are many posts here that have made mistakes because they asked the question too late.

Hi
I also live in Sydney and have followed your build , I have come to a stage where you may be able to help me with. ( See Pic ) I have a free floating slab the same as yours. My question is the second slab that you have placed on the first , is it concrete or Insulating concrete?.
When you embedded the insulating brick into sencond slab does it make contact with the first slab and have you had any problems with heat transfer.?
The piece of marble is just sitting on the shelf , just to get an idea how it will look.

Hi there Grunt, the first slab is 100mm reinforced concrete and all i did was sit the insulation bricks on it and form up the edges before pouring the concrete around them.
I don't get any heat transfer now but when the oven was new and the insulation bricks were damp it got up to 65 degrees C. If i were to do it again i would sit the bricks on their edge which would give me 10mm more thickness and a little more insulation effect.
I can cook pizzas in the night, close the thin plywood door with no insulation and still have enough residual heat to cook bread the next morning and a roast after that for dinner. Where are you getting your bricks and mortar from?
Good luck and if you need more info feel free to ask.

Hi
Thanks for the prompt reply and info , I will be using a lighter color brick to yours but not fire brick to build the dome
Field Furnace at Wetherill Park for the Insulation Brick + Floor Tiles and the Mortar, unless you know of any other place in Sydney

No, they are the best! I would be interested in seeing what type of brick you are using and where they came from. you do not want to use commons as I know they WILL break up after a couple of pizza nights. Pay attention to the warnings on this forum about bricks that crumble when hit with a bolster or hammer, you need your bricks to crack or break into stable pieces. I have seen an oven built in Sydney from common bricks that is crumbling to the touch now after no more than 20 cycles.
Where about in Sydney are you?

HI
I have a pallet approx of these bricks , they are what is used in our house . approx 20 plus years old , some have rounded frogs and some are rectangular .
the rounded ones are a lot lighter in colour , whereas the rectangular ones are darker and have like glaze marks ,
I think they are pressed bricks and are very hard .
the first pic shows a complete brick .
the second a brick i cut in half using bolster and brickies hammer ,
the third is half a brick that I had to hit about 10-15 times with brickies hammer to break.let me know what you think
I am in Ambarvale , near Campbelltown,
Thanks again for the info
Best Grant

I can't see how hitting a brick with a hammer can predict its ability to withstand thermal shock. If you take an insulating firebrick, which has excellent refractory properties and good for 1500 C +, strike it with a hammer and it will crumble. Also, it is the materials the bricks are made from that give it the refractory properties not the temp they have been fired to. Anyone know where this hammer theory comes from, or is it one of those old wives tales?
