    So decided to wait with further curing until perlite and vent were in place.
    How is it coming along?

    It looks from the photos that you have already started curing.

    Are you concerned it will draw lots of heat out of the oven?
    Are you concerned it will heat and distort at a different rate to the bricks and cause problems down the track?
    The steel arch is there for a couple of reasons:

    - all commercial Neapolitan ovens have a steel arch/entry.
    - the previous oven I did had a cast vent (doing it in brick was beyond me..) and I wanted to do something more traditional.

    Re expansion, cracking etc: Like I said above, all Neapolitan ovens have a steel arch and have been built like that for many, many years (centuries). So if there was going to be an issue, they would have found out about it by now.

    I fitted a form made from some flashing steel and poured/shaped perlite concrete around the side and over the top. My vent has been fabricated, so if next weekend the weather is any good, I can fit it and do some curing.

    Wrapped the oven in some CalSil blanket and chicken wire/mesh.

    Next stage: make a form around the dome from some bendy plywood and pouring about 4 inches of perlcrete around the sides and over the top.

    Can't have enough insulation...

    That is correct. Although in truth, because the refractory mortar I used is really strong (by way of trial I tried to smash two pieces of brick that were bonded together with it. Rather than breaking the mortar, it broke the brick), I suspect it would be fine without the steel cable.

    But I'd rather be safe than sorry.

    No, just made it sufficiently damp/wet and that did the trick.

    Hey KP - That really is an amazing, no bs account of building an oven. How long did that take? You mentioned SS cable, where does that fit in?

    Cheers ........... Steve

    OK. This is where things are at as of now:

    Dome mortared and sand form removed.

    Stainless steel cable around the dome attached.

    Removed all the logs and most of the sand (there is still a bit to go as you can see in the last pic).

    The last shot shows the inside but unfortunately no picture of the dome brickwork. I decided to cover the sand form with damp newspaper because I didn't want any sand sticking to the mortar (it might drop onto a pizza later at some stage). And the newspaper will just burn off when I start firing / curing the oven.

    Now onto insulation and then curing..
